Software Defined Networking (SDN)

SDN is an approach to networking that enables the programmatic control of a network. Such an approach is more congruent with cloud computing than traditional rigid networking.

One of the drivers behind SDN is a desire to create a more flexible approach. When implementing SDN in practice, automation and flexibility are key concepts.

What are the main reasons companies invest in Software-Defined Networking solutions? First of all, networks that use SDN are more flexible, allowing updates and changes to be made faster. Moreover, the number of errors and downtime are reduced, as automation in many cases eliminates the human factor. Because network operators have full topology visibility, SDN also allows for more efficient network traffic routing, especially when traffic is peaking. Last but not least, SDN creates an important technological advantage in networking. Introducing a new functionality in networks is extremely time-consuming and prohibitively expensive. Time-to-market is even worse, if there are multiple vendors in a network. But if a company can introduce its innovations faster, it will gain considerable competitive advantage. This is precisely why tech giants including Google, Amazon or Facebook have adopted SDN in their production environments.

Data Center Acceleration (DC)

Like all networking domains, a data center’s networks also evolve. L2-based data centers are evolving to IP fabrics, while standard protocols like STP are being replaced by BGP, EVPN, VXLAN or MPLS. The new approach to building a data center allows for greater robustness, better scalability and resource usage optimization.

The adoption of new technologies within a DC domain poses challenges that are common for the entire networking domain. How should an existing solution be migrated to a new one? What equipment would be the most appropriate to fit the purpose? Can some of the legacy devices be used in a new solution? How can two or more locations be connected to build a resilient infrastructure?

Automation is yet another challenge in building a next generation DC. For older DCs, resource planning (like VLAN numbering), configuration and maintenance is often done manually. With IP-fabrics, a certain level of automation is desirable, at least for configuring the devices and connecting the workloads including bare metal servers, virtual machines and containers. BMSs require proper switch(es) configuration, but for VMs and containers the most common approach would be to use a software router or adopt an SDN

Last but not least, every data center needs a good monitoring system which can show the health of both the infrastructure and virtual entities.

Wide Area Network (WAN)

Wide Area Network is a broad subject. From our point of view, it encompasses all of the kinds of networking telecommunication operators or Internet Service Providers have. WAN is usually a mix of different types of technologies: from the old ones like ATM to new ones like SD-WAN. This mix of technologies is a natural result of these networks evolving, with new solutions and services constantly being added, while legacy ones had to be supported no less as they widely were used by loyal customers.

A telco network is a single organism but with well-defined and distinct domains: wireline access or radio access, aggregation, IP/MPLS core and edge, mobile packet core and others. Each of these domains serves a different purpose and uses different networks protocols (at least to some extent). Thickening the complexity, new solutions are constantly being added on top of these, including: cloud connectivity (both private and public) and SD-WANs.

The never-ending evolution means some of these domains are ready to be migrated to new technologies, but some are not. The most common and widely adopted approach is Network Function Virtualization (NFV). This allows for the use of virtual entities like Virtual Machines to serve network functions (for example, a firewall) that were previously realized by dedicated hardware devices. NFV introduces new connectivity challenges, the need for using either proprietary DCs or public clouds, and SDNs and monitoring challenges.

Software-Defined Wide Area Network (SD-WAN)

Software-Defined Wide Area Network (SD-WAN) is the implementation of SDN into WAN topology.

SD-WAN architecture allows enterprises to use different uplinks (MPLS, LTE etc.) across different branch offices. A centralized control plane, meanwhile, enables administrators to configure devices remotely. Administrators can also configure more advanced algorithms to manage network traffic.

SD-WAN can considerably enhance a traditional WAN architecture, offering such benefits as:

Reduced costs
Increased application performance
More intelligent directing of traffic across the WAN
Faster deployment

Wireless Local Area Network (WLAN)

Wireless local-area network (WLAN) operates in the 2.4 GHz, 5 GHz, and 6 GHz bands. The deployment of Wi-Fi is expected to cater to all market segments and extend support for emerging segments that require a high level of user interactivity, immersion, and reliability, such as augmented reality (AR), virtual reality (VR), and extended reality (XR).

The principal target markets are environments that demand high performance in terms of peak throughput, high network and link efficiency, increased reliability, and low latency in both commercial and consumer market segments represented by a variety of use cases, including:

Streaming ultra-high definition video
Multi-user AR/VR/XR
Automotive
Hybrid work and rich telepresence
Immersive gaming and entertainment
Emergency Preparedness Communication Services
Industrial Internet of Things
Immersive 3-D training
