Achieving Optimal Timestamp Accuracy on 7150 Platforms
Background The launch of the Arista 7150S in 2012 delivered the industry’s first product to offer high speed networking with high granularity packet time stamping in an Ethernet switch/router platform. This article will review how time stamping has evolved since. Arista first conceived of the capability to leverage the 7150S to intersect with an emerging network monitoring market requirement that would improve the ability to capture the proper order of traffic captured by network analysis tools over the out of band (OOB) tap aggregation (aka network packet broker) infrastructure. Applying timestamps to packets at the network ingress ports of the...
