What is Wi-Fi 6 (802.11ax), and why do we need it?

Wi-Fi has become an indispensable technology in enterprise networks, supporting enough bandwidth and individual channels to make all-wireless LANs feasible, thanks in large part to 802.11ax, the standard more commonly called Wi-Fi 6.What is 802.11ax (Wi-Fi 6)? Wi-Fi 6 was officially certified in 2020 and has quickly become the de facto standard for wireless LAN technology (WLAN), superseding Wi-Fi 5 (802.11ac). Wi-Fi 6 delivers improved performance, extended coverage and longer battery life compared to Wi-Fi 5.Wi-Fi 6 was originally designed to address bandwidth problems associated with dense, high-traffic environments such as airports, stadiums, trains and offices. However, the explosion of IoT devices that need to connect wirelessly to edge devices, and the ever-increasing bandwidth needs of new data-thirsty applications has rendered Wi-Fi 6 not exactly obsolete on arrival, but certainly not sufficient for some use cases.To read this article in full, please click here

Exium expands SASE, 5G-based security for midsize enterprise networks

California-based secure networking company Exium is adding a new, on-premises SASE ( secure access service edge) node to its cloud-based network management and security platform, bringing that system's capabilities directly to end users' data centers.SASE is a Gartner-defined model that combines SD-WAN with cloud services. It aims to provide a single, cloud-based service that can dramatically simplify the deployment of modern, identity-based security technology. Gartner's definition of SASE mandates the use of five specific security technologies, including secure web gateways, SD-WAN, firewall-as-a-service, a zero-trust network access model and a cloud access security broker to keep data in cloud systems secure.To read this article in full, please click here

What is NFV – Network Function Virtualization

Network Functions Virtualization (NFV) was founded by the European Telecommunication Standard Institute (ETSI) with Industry Specification Group (ISG) which contains seven of the world’s leading telecom network operators.

A challenge of large-scale telecom networks is increasing the variety of proprietary hardware and launching new services that may demand the installation of new hardware. This challenge requires additional floor space, power, cooling, and more maintenance. With evolving virtualization technologies in this decade, NFV focuses on addressing the telecom problems by implementing network functions into software that can run on server hardware or hypervisors.

Furthermore, by using NFV, installing new equipment is eliminated and it will be related to the health of underlay servers and the result is lower CAPEX and OPEX.

There are many benefits when operators use NFV in today’s networks. One of them is Reducing time-to-market to deploy new services to support changing business requirements and market opportunities for new services.

Decoupling physical network equipment from the functions that run on them will help telecom companies to consolidate network equipment types onto servers, storage, and switches that are in data centers. In NFV architecture, the responsibility for handling specific network functions (e.g. IPSEC/SSL VPN) that run in one Continue reading

Bilateral Peering and Multilateral Peering

Bilateral Peering is when two networks negotiate with each other and establish a direct BGP peering session. In one of the previous posts, Settlement Free Peering was explained, in this post, both Bilateral and Multilateral Peering will be explained and both are deployment modes of Settlement Free Peering.

This is generally done when there is a large amount of traffic between two networks. Tier 1 Operators just do Bilateral Peering as they don’t want to peer with anyone, other than other Tier 1 Operators. The rest of the companies are their potential customers, not their peers.

Multilateral Peering

As mentioned above, Bilateral Peering offers the most control, but some networks with very open peering policies may wish to simplify the process, and simply “connect with everyone”. To help facilitate this, many Exchange Points offer “multilateral peering exchanges”, or an “MLPE”.

An MLPE is typically an exchange point that offers a “route-server”, allowing a member to establish a single BGP session and receive routes from every other member connected to the MLPE.
Effectively, connecting to the MLPE is the same as agreeing to automatically peer with everyone else connected to the MLPE, without requiring the configuration of a BGP session Continue reading

What is CDN – Content Delivery Networks?

Content Delivery Network companies replicate content caches close to a large user population. They don’t provide Internet access or transit service to the customers or ISPs but distribute the content of the content providers. Today, many Internet Service Providers started their own CDN businesses as well. An example is Level 3. Level 3 provides its CDN services from its POP locations which are spread all over the World.

Content distribution networks reduce latency and increase service resilience (Content is replicated to more than one location). More popular contents are cached locally and the least popular ones can be served from the origin

Why CDN – Content Delivery Networks are necessary?

Before CDNs, the contents were served from the source locations which increased latency, thus reducing throughput. Contents were delivered from the central site. User requests were reaching the central site where the source was located.

CDN - Content Delivery Networks

Figure 1 – Before CDN

With CDN Technology, the Contents are distributed to the local sites.

Amazon, Akamai, Limelight, Fastly, and Cloudflare are the largest CDN providers which provide services to different content providers all over the world. Also, some major content providers such Continue reading

Simplify and Standardize Mantra Encounters Reality

I’m usually telling networking engineers seriously considering whether to automate their networks to cleanup their design and simplify the network services first.

The only reasonable way forward is to simplify your processes – get rid of all corner cases, all special deals that are probably costing you more than you earned on them, all one-off kludges to support badly-designed applications – and once you get that done, you might realize you don’t need a magic platform anymore, because you can run your simpler network using traditional tools.

While seasoned automation practitioners agree with me, a lot of enterprise engineers face a different reality. Straight from a source that wished to remain anonymous…
