Embedded tools for network delay measurement

Requirements on end-to-end latency and jitter are becoming more and more important due to new real-time services 'delay sensitive' to be transported. Capability to support measurements of end-to-end latency and jitter is essential in particular for Carrier Ethernet products [1]. This paper addresses a concrete example of measurement of the end-to-end latency and jitter in a Carrier Ethernet network exploiting Ethernet OAM tools. In particular this paper addresses the extension of usage of ITU-T Y.1731 [2] tools to multipoint-to-multipoint applications over MPLS-TP network. Results of the implementation over a real optical packet platform are also presented.
