The performance metrics typically needed are the traffic, delay and loss-rate between two access-points. In many cases, the network provider needs to have the network operate within specific performance expectations, such as those specified within a Service Level Agreement (SLA) contract. A continuous measurement of the performance metrics is needed to ensure compliance with the SLA. However, traditional IP performance approaches typically include snap-shots of network performance at one single point, and do not offer much support for network performance between two customer access points. The main difficulty associated with the measurement is that neither of the access-points are the source or destination of an IP packet. In this paper, we present a scheme for network performance monitoring that can be used to monitor the IP performance problem between two access-points, and to verify that a specific SLA contract is being satisfied %U http://www.ee.columbia.edu/dvmm/publications/99/mandis_spects99.pdf %8 July %D 1999
