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 are
becoming key requirements for path computation along with other
constraints and metrics. These metrics are associated with the
Service Level Agreement (SLA) between customers and service
providers. The Link Bandwidth Utilization (the total bandwidth of a
link in current use for the forwarding) is another important factor
to consider during path computation.
IGP Traffic Engineering (TE) Metric extensions describes mechanisms
with which network performance information is distributed via OSPF
and IS-IS respectively. The Path Computation Element Communication
Protocol (PCEP) provides mechanisms for Path Computation Elements
(PCEs) to perform path computations in response to Path Computation
Clients (PCCs) requests. This document describes the extension to
PCEP to carry Latency, Latency Variation, Packet Loss, and Link
Bandwidth Utilization as constraints for end to end path computation.
