L2 RDMA over Converged Ethernet (RoCE) Profile for Wireshark
RDMA over Converged Ethernet (RoCE) is a network protocol that enables Remote Direct Memory Access (RDMA) over Ethernet networks. RDMA is a technology that allows data to be transferred directly from the memory of one computer to another without involving the operating system or CPU, which reduces latency and increases throughput. RoCE enables this capability over standard Ethernet infrastructure, making it possible to achieve high-performance data transfers similar to those found in InfiniBand networks, but with the widespread use and familiarity of Ethernet. This makes RoCE particularly attractive for data centers, cloud services, and high-performance computing environments where low latency and high throughput are crucial.
The "converged Ethernet" aspect of RoCE refers to its ability to run on Ethernet networks that support both traditional network traffic and storage or data transfers using RDMA. This convergence allows organizations to use the same Ethernet infrastructure for multiple types of traffic, reducing the need for specialized hardware and simplifying network management. RoCE is commonly used in applications that require high-speed data movement, such as storage area networks (SANs), large-scale databases, and virtualized environments, where it helps improve efficiency by offloading data transfer tasks from the CPU.
This profile helps Wireshark users to focus on these protocols.
