Why is Lossless Ethernet important?

C1b3rWall Academy Module 1 on networks and architectures covers the fundamentals needed to understand the new technologies that are being developed in the area of Data Center networking.

“Lossless Ethernet in High Performance Converged Networks” is the title of the lecture that belongs to Module 1 of C1b3rWall Academy 2021: “Networks and architectures”, which is being taught by Victor Jimenez Ramos, IP CTO of Huawei Enterprise Spain who has more than 20 years of experience in the area of IP Networking and is a specialist in the design and the practical application of networking solutions in Campus and Data Center networks.

Ethernet is a fairly old technology (its first uses date back to the 80s) which has been gradually gaining popularity on a global scale. Its latest version was created in 2017, offering effective transmission rates of 400Gbps and running at a speed of over 1Tbp. This technology is known for its simple protocol and for being low-cost, easy to use and scalable.

What is the reason for Ethernet’s success?

Ethernet has succeeded because of the characteristics described above (low cost, protocol simplicity…), but it is important to point out what it does not do and what its weak points are: reliability, efficiency and non-deterministic origin, without an exact pattern of when data are sent or how they arrive. For this reason, in the late 2000s, there was renewed interest in finding an alternative that would prevent the loss of frames or packets, so that Ethernet could be used for networking across Data Centres.

The availability of efficient but at the same time low-cost network systems can help make the most of the compute and storage infrastructure, while keeping the cost and complexity of the learning curve to a minimum. You can read the full article on News-365.
