details

Network infrastructure comprises the hardware and software components that enable communication and data transfer. It includes (physical and virtual elements like) routers and switches, servers as well as protocols, and security measures, forming the backbone of modern connectivity for businesses and individuals.

Enhancing SONiC — the process of developing custom network functionality

In the previous article, we introduced our reasons for exploring SONiC’s potential in terms of building new network functionalities, presented a use case, and described how we approached the task on the logical level. In this part, we want to share the experience we have gained through the development process. Note: please do not treat this as a comprehensive developer’s guide. What we explain here is our process and the key takeaways from it, which we believe might come in handy for other SONiC developers.

Developing custom network functionality using SONiC

Market analyses claim that in the future, networking will shift more and more towards so-called Open Networking. Open Networking relies mainly on hardware and software disaggregation, i.e. with open standard bare-metal equipment and a choice of independent NOS (Network Operating System). Such an approach fits with the main industry trends, like Software-Defined Networking, virtualization, containerization and of course, cloud computing.\Other benefits of open networking include: Flexible architecture

The Catalyst 9300 platform by Cisco — what it is and how you can use it

Network infrastructure has to handle ever-increasing amounts of data. It enables data exchange between employees’ devices as well as communication with the internet. However, companies should be aware of possible external and internal attacks that can infiltrate a network infrastructure and cause security breaches. Therefore, the creation of network infrastructure has to be both efficient and secure. In this article you will learn how you can use Cisco’s Catalyst 9300 platform to mitigate these risks.

What is a SDN controller? SDN controllers in networks

A Software-Defined Networking (SDN) controller is a central component of SDN architecture. It provides control over the network elements (in the managed domain).

Managing data center physical infrastructure with Tungsten Fabric

A data center’s physical infrastructure can consist of multiple devices including switches and routers. Managing them can be a time-consuming and error-riddled process. Adding an SDN solution to your legacy data center network makes the entire problem even more complex. Tungsten Fabric, an open-source SDN controller, may be the answer. Read on to know more. Modern data centers are built as flat two/three layers of deeply interconnected devices known as a fabric. This leaf-spine architecture is robust and easy to scale out by adding new devices instead of replacing older devices with more powerful ones.

The modern, interoperable DC — Part 3: Seamless and secure connectivity for edge computing and hybrid clouds (video)

In the third part of our “Modern DC” webinar series we focus on connectivity with resources located beyond the local data center, somewhere in the Internet. This includes extending Layer 2 and Layer 3 tunnels to public clouds (such as AWS, Azure and GCP), branch offices, Edge Computing servers and IoT devices based on single-board computers.
