Miercom was engaged by Cisco Systems to independently assess Catalyst switch support for Audio Video Bridging (AVB), as specified in the IEEE's 802.1BA standard and subordinate specifications. AVB support enables the transmission over Ethernet of time-sensitive audio and video streams that had traditionally required their own dedicated network and cabling.
Testing was conducted in a well-equipped lab using the latest IxNetwork AVB test system from Ixia, running software that fully exercises all the protocols and functionality of the IEEE AVB standard. Testing employed six Cisco Catalyst 9300 and 3850 switches connected in series, comprising a full seven-hop network—the IEEE-specified configuration for measuring AVB performance.
