What is dcb association?

DCB (Dynamic Circuit-Based) Association is a method used in computer networking to provide Quality of Service (QoS) for traffic streams over IP networks. This technology enables the creation of a virtual circuit between two endpoints in the network, which can guarantee a particular amount of bandwidth and a specific Quality of Service for a particular data flow.

DCB Association works by allocating different priorities to different types of data flows based on requirements like latency, throughput, and data loss. By prioritizing traffic, DCB Association can improve network performance, reduce congestion, and improve the reliability of data transfers, particularly for real-time applications like video conferencing and live streaming.

DCB Association builds upon the IEEE Data Center Bridging (DCB) standard, which specifies a set of enhancements to Ethernet for supporting converged data center traffic such as storage, data, and video. It is typically used in data center networks and is supported by the majority of data center switch vendors.
