In certain networks like financial information network (stock/
commodity trading) and enterprises using cloud based applications,
Latency (delay), Latency-Variation (jitter) and Packet loss is
becoming a key requirement for path computation along with other
constraints and metrics. Latency, Latency-Variation and Packet Loss
is associated with the Service Level Agreement (SLA) between
customers and service providers.
[MPLS-DELAY-FWK] describes MPLS architecture to allow latency, loss
and jittering as properties. [OSPF-TE-EXPRESS] and [ISIS-TE-EXPRESS]
describes mechanisms with which network performance information is
distributed via OSPF and ISIS respectivily. This document describes
the extension to PCEP to carry Latency, Latency-Variation and Loss as
constraints for end to end path computation.
