Evolution of management protocols for network devices

Connecting and powering network devices (be it in the form of physical hardware or virtualized/containerized functions) is not enough to make them operational - the devices have to be configured before using them to forward / filter / load balance, etc. the traffic.

Linux network troubleshooting — commands and examples

Linux is a popular and powerful operating system that is widely used in both personal and professional settings. One of the key features of Linux is its robust networking capabilities, which make it an excellent choice for a wide range of networking tasks. The Linux network stack has grown significantly throughout the years and currently supports not only basic functionalities but also advanced and complex features (e.g. network namespaces allowing the creation of different and isolated network stack instances).

SONiC adaptation for custom functionality — the PoC reveal

In the previous part, we introduced both the higher and the lower level concepts necessary for understanding the use case scenario as well as a proposed solution, starting from its prerequisites through to the design and finally the implementation. In this concluding article of the series, we want to eventually answer the initially-posed question: can we adapt a SONiC switch to be able to deliver a custom functionality? In our case, a load balancing feature for GTP-U. In order to conduct this PoC we needed to:

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

Is Network Service Mesh a service mesh?

Service mesh solutions are increasingly becoming an important element of modern applications built on the basis of microservices architecture. But here and there, you can also hear about a project called Network Service Mesh. Is it another variation on the service mesh theme or something completely different? A service mesh is a kind of “network” that connects all microservices within a given application. In fact, it is extra software that acts as an intermediary layer between services and provides a wide range of functions in the fields of security, observability, and traffic management, as well as reliability and resilience.
