Lossless Network

A lossless network is one where the devices comprising the network fabric are configured to prevent packet loss by using DCB Data Center Bridging. DCB is a collection of standards developed by IEEE for creating a converged data center network using Ethernet. protocols. One of the primary objectives of designing network solutions that incorporate RoCE is to deploy a lossless fabric. Even though the RoCE standards do not demand lossless networks, RoCE performance can suffer when a lossless network is not provided. With that as a premise, it is recommended that a lossless fabric be considered as requirement for RoCE implementations. Lossless fabrics can be built on Ethernet Ethernet is a network protocol for data transmission over LAN. fabrics by leveraging DCB protocols.
