Abstract:
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
(delay), Latency-Variation (jitter) and Packet loss as properties.
[OSPF-TE-EXPRESS] and [ISIS-TE-EXPRESS] describes mechanisms with
which network performance information is distributed via OSPF and
ISIS respectively. This document describes the extension to PCEP to
carry Latency, Latency-Variation and Loss as constraints for end to
end path computation.
