The Credit Based Shaper (CBS) was developed in 2009 by the IEEE 802.1 working group for the TSN Audio/Video Bridging (AVB) predecessor technology. The shaper assigns send credits to data streams.

Credit-based fair queuing is a computationally efficient alternative to fair queueing. Credit is accumulated to queues as they wait for service. Credit is spent by queues while they are being serviced. Queues with positive credit are eligible for service. The rate of credit accumulation and release can be adjusted on a queue-by-queue basis to produce a weighted queuing behavior. Credit-based queuing is used in Resilient Packet Ring networks and in the IEEE 802.1Qav compo… WebA credit-based shaping algorithm is available on the two highest priority queues and is defined in the standard 802.1Qav: Forwarding and Queuing Enhancements for Time …
