Terminology for Benchmarking Link-State IGP Data-Plane Route Convergence

“…To enable collecting statistics of Out-of-Order Packets per flow (see [Th00], Section 3), the Offered Load SHOULD consist of multiple Streams [Po06], and each Stream SHOULD consist of a single flow . If sending multiple Streams, the measured traffic statistics for all Streams MUST be added together.…”

“…A lost packet, a packet with a Forwarding Delay exceeding the Forwarding Delay Threshold, a corrupted packet, a Duplicate Packet [Po06], and an Out-of-Order Packet [Po06] are Impaired Packets.…”

Traffic Management Benchmarking

“…However, [RFC4737] and [RFC4689] provide recommendations for sequence tracking, along with definitions of in-sequence and out-of-order packets.…”

“…[RFC4689] defines the general function of sequence tracking, as well as definitions for in-sequence and out-of-order packets. Out-of-order packets will be counted per [RFC4737].…”

Methodology for Benchmarking MPLS Traffic Engineered (MPLS-TE) Fast Reroute Protection

“…In addition, this methodology considers the packets in error and duplicate packets [RFC4689] that could have been generated during the failover process. The methodologies consider lost, out-of-order [RFC4689], and duplicate packets to be impaired packets that contribute to the failover time.…”
