End-User Traffic Rising, More Traffic Migrating to Private Networks

October 15, 2018Business, Technology 12,837

What’s on the horizon for the global internet? We have a few ideas.

International internet bandwidth and traffic growth has gradually slowed in recent years, but remains brisk. And IP transit price declines continue globally, but significant regional differences in prices persist around the world.

The combined effects of new internet-enabled devices, growing broadband penetration in developing markets, higher broadband access rates, and bandwidth-intensive applications will continue to fuel strong internet traffic growth.

While end-user traffic requirements will continue to rise, not all of this demand will translate directly into the need for new long-haul capacity.

Aggregate international internet capacity and traffic growth rates are slowing as the global internet matures and more traffic migrates to private networks. A variety of factors shape how the global internet will develop in coming years.

Transit Costs and Prices

Not only does the transit market exhibit both robust volume growth and sharp price decline, but the escalating bandwidth use actually lowers unit costs and enables the price decline, ensured by stiff competition.

The transit market is in the early stages of 100 Gbps port adoption but is poised to ramp up considerably in 2019, driving unit prices down further. Equipment costs for routers populated with 100 Gbps ports has reached parity with 10 Gbps on a unit basis. Once 10 Gbps inventory begins to clear, few incentives remain to invest in 10 Gbps platforms where scale warrants 100 Gbps.

Not only does the transit market exhibit both robust volume growth and sharp price decline, but the escalating bandwidth utilization actually lowers unit costs and enables the price decline, ensured by stiff competition.

Transit lags the transport market where 100 Gbps is well entrenched in the backbone and network operators are actively exploring higher line rates and next-generation optical transmission schemes. While single GigE sales have declined considerably from the heyday 10 years ago, 10 Gbps sales pervaded for years, suggesting that the next port size will not quickly displace the global market for 100 Gbps—despite brisk traffic growth.

Content Delivery Networks and Caching

The increased reliance on direct connections to content providers and the use of caching will continue to have a localizing effect on traffic patterns and dampen international internet traffic growth. As demand for content and applications grows in new locations, CDN nodes and caches will be deployed into these areas.

While the increase in broadband users and access rates will continue to drive traffic growth in access networks, much of this growth may be managed locally within a network and may not lead to proportional increases in traffic on international links.

The Rise of Content Provider Networks

The largest content providers’ private networks are having a major impact on the growth of internet capacity requirements. The focus of backbone providers has started to facilitate interconnection with handful of large content providers who account for the majority of traffic.

As the content providers extend their networks into new locations, backbone operators will continue to optimize their topologies in response.

As the content providers extend their networks into new locations, backbone operators will continue to optimize their topologies in response. In some cases, backbone operators may reduce capacity or shift capacity to new locations. Additional companies, including Akamai, Dropbox, and Oracle, are in the process building global networks, which will shift additional traffic away from the public internet. As a result, the pace of international internet capacity and traffic growth appears likely to continue a pattern of broad deceleration.

VPLS vs MPLS: What’s the Difference?

October 15, 2018Business 20,108

The Internet has undergone tremendous changes and broken the barriers from the impossibilities to the possibilities. To seamlessly and securely get access to the Internet or Web is what we’re seeking along the way. VPLS and MPLS are two competing technologies to direct network traffic, letting you have speedy data transfer and communication. What is a VPLS or MPLS network? What’s the difference between VPLS vs MPLS? We’re gonna to elaborate them one by one.

What Is MPLS?

MPLS (Multiprotocol Label Switching) is a type of communication that enables a service provider to provision cost effective and flexible “Virtual Private Networks” across a shared core network infrastructure. MPLS is used to send data and network traffic along the most efficient routes, which may be predetermined and are communicated using labels. Packets are carried on predetermined routes along point-to-point connections through label switch routers (LSRs) until they arrive at their destination. In MPLS network, the MPLS switch (eg. FS S5800-48F4S SFP switch) transfers data by popping off its label and sending the packet to the next switch label in the sequence. MPLS perfectly integrates the performance and traffic management capabilities of Layer 2 switching with the scalability and flexibility of Layer 3 routing.

MPLS Network

What Is VPLS?

VPLS (Virtual Private LAN Service) is a service that uses MPLS and VPN (Virtual Private Networking) to securely and seamlessly connect multiple LANs over the Internet, making them appear as if they were all on the same LAN. VPLS enables a service provider to extend a Layer 2 network across geographically dispersed sites using a shared core network infrastructure. VPLS works by creating a virtualized Ethernet switch at the provider’s edge to link remote sites. VPLS happens at Layer 2, and the carrier builds out the network, but the customer can do their own routing if they wish. This approach is ideal for corporations that have multiple data center footprints and office or remote locations that require low-latency connections between sites.

VPLS Network

VPLS vs MPLS: Factors to Consider When Choosing Them

When deciding over VPLS vs MPLS for connectivity between remote locations, there are multiple factors to consider. We’ll look into them one by one.

Switching Layer

One of the main benefits of VPLS over MPLS are the levels of security offered. As aforementioned, VPLS extend a Layer 2 network across geographically dispersed sites using a shared core network infrastructure. While MPLS perfectly integrates the performance and traffic management capabilities of Layer 2 switching with the scalability and flexibility of Layer 3 routing. VPLS does not share layer 3 routing tables with the service provider, while MPLS may do so, means that VPLS is generally the better solution for highly-sensitive data.

Network Size & Traffic

Generally, MPLS can deliver a wider type of network traffic than VPLS. VPLS is typically used for fewer locations that need very high speeds, very simple networks with high performance and high security. Thus, if you desire to connect entities such as data centers across the long-haul network backbone, VPLS is preferable as an Ethernet-based connection strategy. If a customer had hundreds of locations across the country who needs voice, data and video traffic to be carried to all locations, MPLS might make more sense because it is protocol-agnostic and can handle multiple types of traffic. MPLS may be an even clearer choice where large numbers of branches are involved.

Levels of Scalability

Another key difference between MPLS and VPLS is the inherent level of scalability. Due to the manner in which these two technologies interact with your network, MPLS is considered to be far more scalable. Using a backbone of MPLS for maximum network access and scalability, together with VPLS connections for more sensitive data often represents the best possible compromise, you would make the most of both protocols and substantially increase network efficiency.

Conclusion

Although MPLS and VPLS are different technologies, they are not mutually exclusive. Many businesses deploy both MPLS and VPLS protocols within their network in order to get the best of both worlds. FS provides gigabit ethernet switch and 10gbe switch which support both MPLS and VPLS. All these switches comes with rich L2/L3 business processing ability for core switching networks.

MPLS vs Ethernet for WAN Connectivity

October 15, 2018Technology 14,156

A WAN (Wide Area Network) is a communications network that spans geographically dispersed areas such as across cities, states or countries. A business may have a WAN comprised of cloud services, its headquarters and smaller branch offices, so the WAN is used to connect all sites together. The two most popular WAN connectivity options are MPLS ((Multiprotocol Label Switching) and Ethernet. To help subscribers analyze the differences between MPLS and Ethernet, this side-by-side MPLS vs Ethernet comparison provides a quick overview of the pros and cons of each WAN connectivity option.

MPLS vs Ethernet

What is MPLS?

MPLS is a protocol for efficient network traffic flow between multiple locations. MPLS operates similarly on a data switch and router, sitting between layers 2 and layer 3 network. MPLS uses labels for fast packets forwarding and routing within a network. In MPLS network, the MPLS switch (typically Gigabit Ethernet switch and 10GbE switch) transfers data by popping off its label and sending the packet to the next switch label in the sequence. The main benefits of MPLS network service are listed as below.

Reliability: MPLS is most widely used way to interconnect data centers with remote offices and branches to other branches since MPLS does require an entire block of IPs.
Service: With MPLS, there is a higher service level agreement that include delivery guarantees for speed and class of service (COS), unlike consumer broadband.
Labor Cost: MPLS allows businesses to leave WAN routing to the service provider and keep fewer WAN engineers on staff.

What is Ethernet?

Ethernet is a network protocol that controls how data is transmitted over a LAN (Local Area Network), such as those in a room, office, building or campus. As a point-to-point system, an Ethernet network uses Ethernet cables to connect PCs, switches or routers. Most desktop and laptop computers come with integrated an Ethernet card so that it’s easy to connect. Although the functionality of Ethernet is not as high-performing as that of an MPLS network, there are still some merits making it appealing.

Affordability: Although the scalability of Ethernet is smaller than that of MPLS, Ethernet is more affordable than MPLS, thus becoming the optimal choice for small and medium sized businesses.
Simplicity: Ethernet is best for connecting one data center to another, including using metro Ethernet to connect corporate sites dispersed geographically.
Professional Resources: Ethernet gives in-house WAN engineers control and responsibility over routing.
Disaster Recovery: Ethernet offers low latency and high output, which is ideal for disaster recovery.
Availability: Ethernet exchanges have made Ethernet WAN services available in more locations.

MPLS vs Ethernet for the WAN

Take a closer look at the subtle difference between MPLS vs Ethernet for the WAN connectivity from the chart below.

Parameter	MPLS	Ethernet
Scalability	Scale to over thousands of sites	Scale to up to hundreds of sites
Application	Interconnect data centers with branch offices and branches to other branches	Interconnect data centers
WAN routing	Leave WAN routing to the service provider and keep fewer WAN engineers on staff	Give WAN engineers control and responsibility over routing
WAN protocol behavior	Handle any-to-any connectivity, including voice and video	Offer low-latency and high-throughput, which is ideal for disaster recovery.
Quality of service (QoS)	QoS options to enable preferential treatment of latency-sensitive traffic like VoIP	Network engineers can bypass QoS complexity by hooking switches directly to Ethernet pipes
WAN management	Complex	Simple
Cost	High	Low

Summary

When weighing the pros and cons of MPLS vs Ethernet, make sure to examine your business needs and understand the resources available within the network, as well as what options exist in your geographic area. Most ISPs nowadays also offer an ISP-managed MPLS service, so they can manage the equipment, and basically get an Ethernet handoff to a switch, which is the so called “MPLS over Ethernet”. No matter which solution you would prefer, your network selection will influence the quality, reliability, service and cost of your WAN connectivity.

Cloud Computing vs Big Data: What Is the Relationship?

October 15, 2018Technology 14,370

Cloud computing and big data are two of the most trending terms in the ever-lasting IT sector nowadays. You may think that they both do the same thing but actually, both of them have their own ways to work to perform. Cloud computing vs big data, what are they? What is the relationship between them?

cloud computing vs big data

Cloud Computing Tutorial

Cloud computing is a technology used to store data and information on a remote server rather than on a physical hard drive. It uses the servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer. It means accessing resources of organization from any remote location in the world. In simple term accessing RAM, HDD, Processor of organization’s server from laptop, desktop from any of the location where Internet is available.

what is cloud computing with example

As shown in the figure above, cloud computing is collection of different services, providing services to end user via the Internet. Services like storage, virtual desktop applications, Web/App hosting process power from servers. In the following architecture, the infrastructure built to provide services is called cloud computing. This infrastructure from where the services gets accessible is front end.

Big Data Wiki

The term big data is very popular nowadays, representing huge sets of data that can be further processed to extract information. Big data carries hidden patterns and algorithms which are unlocked by using various tools available in the market. These data sets are further analyzed to provide business insights. Big data is all about storing and processing of data that is exponentially growing these days. Giants like Google, Facebook are having their own data centers to keep track and to secure their users’ data. That’s also why many big companies are equipped with reliable network equipment (including the server, router or fiber switch) for data storage or traffic forwarding in their data centers. For high performance and cost-effective enterprise routers, Gigabit Ethernet switch and 10gbe switch, FS is a case in point.

what is big data technology

Big data requires a large amount of storage space. While the price of storage continued to decline, the resources required to leverage big data can still pose financial difficulties for SMBs (small to medium sized businesses). A typical big data storage and analysis infrastructure will be based on clustered network-attached storage (NAS). Clustered NAS infrastructure requires configuration of several NAS pods with each NAS pod comprised of several storage devices connected to an NAS device. The series of NAS devices are then interconnected to allow massive sharing and searching of data.

Key Comparisons Over Cloud Computing vs Big Data

The cloud computing works in a consolidated manner, while the big data comes under the technology of cloud computing. The crucial difference between cloud computing vs big data is that cloud computing is used to handle the huge storage capacity to provide various flexible and techniques to tackle a magnificent amount of the data. While big data is the information processed with cloud computing platform. The following chart gives a more detailed comparison over cloud computing vs big data.

	Cloud Computing	Big Data
Basic	On-demand services are provided by using integrated computer resources and systems.	Extensive set of structured, unstructured, complex data forbidding the traditional processing technique to work on it.
Purpose	Enable the data to be stored and processed on the remote server and accessed from any place.	Organization of the large volume of data and information to the extract hidden valuable knowledge.
Working Mode	Distributed computing is used to analyse the data and produce more useful data.	Internet is used to provide the cloud-based services.
Benefits	Low maintenance expense, centralized platform, provision for backup and recovery.	Cost effective parallelism, scalable, robust.
Challenges	Availability, transformation, security, charging model.	Data variety, data storage, data integration, data processing, and resource management.

Cloud Computing vs Big Data: They Work Hand in Hand

Both cloud computing and big data are good at their marks. Cloud computing vs big data: they differ from each other but work hand in hand. They are the perfect combination for data storage and processing. The cloud computing has been a precursor and facilitator to the emergence of big data. If big data is the content, then cloud computing is the infrastructure.

FIBRE AND THE INTERNET: A REASSURING CONSTANT IN A CHANGING WORLD

October 15, 2018Business, Technology 15,028

Twenty-five years ago last week, British scientist Sir Tim Berners-Lee and his team published, for free, the protocols that would create the public Internet. A quarter of a century seems like barely a blink of the eye, but what Berners-Lee unleashed that day has had a profound impact on our lives. Just look at the first ever Internet page to see how far we’ve come.

The world is now on the brink of the Internet of things (IoT) and a big data revolution, which means more data is being created in an Internet minute than ever before. Bandwidth has never been more in demand.

zayo_stopwatch Twenty-five years ago, a minute may have been the loading time for a single web page. Now, according to a report by Excelacom, there are 150 million emails sent, 2.4 million Google search queries and 20.8 million WhatsApp messages sent every minute in 2016. We know that artificial intelligence, virtual reality and driverless cars are just over the horizon. But in reality we have no idea what the world will look like in 25 years – the pace of change is too fast.

This is a phenomenal amount of data. It would not be possible without a scalable network infrastructure. The question is, how do we ensure that we are deploying the right infrastructure today to cope with data demands today and the Internet of tomorrow? The answer comes in a reassuringly familiar form: fibre.

Fibre optic cables work by having a single glass core via which information travels. It wasn’t until research conducted by Dutch and American scientists in 2014 in multi-core technology (the practice of having several glass cores for information to travel down in a cable rather than just one) that we understood fibre’s true potential.

The scientists were able to achieve a top speed of 255 terabits per second – equivalent to 32 terabytes of information a second. To put this into perspective, this equates to downloading a 1GB film in 0.03 seconds. Astonishingly, as a result of this research, it was realised that a single fibre cable could theoretically carry the entire world’s Internet traffic.

This modern technology and its almost limitless bandwidth will be essential to our increasingly digital world. Communication is now instantaneous, with text, audio and video messages travelling at light speed. Data centres store terabytes of information that is critical to businesses and their customers, with this information available instantaneously as and when required. Video content can be watched on-demand using devices that were created under a decade ago.

Fibre optic networks and their capabilities have allowed the world and its data to move forward in such a way that would have been inconceivable 25 years ago.

So what does the next 25 years have in store for the Internet? The amount of data consumed will only increase with time, and technology like driverless cars and smart cities will require an almost limitless amount of bandwidth to run effectively.

The one truth that we do know is that without a scalable, high-capacity fibre network all of these concepts would be nothing more than science fiction.
