1. Performance Monitoring Analysis for L3VPN
Publication: IETF Individual Draft
Publication History: 2014-07
Publication URL: https://tools.ietf.org/html/draft-zheng-l3vpn-pm-analysis-03
Description:
To perform the measurement of packet loss, delay and other metrics on a particular VPN flow, the egress PE need to tell to which specific ingress VRF a packet belongs to. But for L3VPN, multipoint-to-point network model applies, flow identifying is a challenge. This document summarizes the current performance monitoring mechanisms for L3VPN in MPLS networks, and analyzes various solutions and challenges for measuring performance metrics within these networks. This document also identifies various key points which needs to be taken in consideration when designing L3VPN performance monitoring mechanisms. Performance measurements within non-MPLS L3VPN networks is not within the scope of the document.
2. A Framework for L3VPN Performance Monitoring
Publication: IETF Individual Draft
Publication History: 2014-10
Publication URL: https://tools.ietf.org/html/draft-dong-l3vpn-pm-framework-03
Description:
The capability of BGP/MPLS IP Virtual Private Networks (L3VPN) performance monitoring (PM) is important to meet the Service Level Agreement(SLA) for the service beared. Since multipoint-to-point or multipoint-to-multipoint (MP2MP) network model applies, flow identifying is a big challenge for L3VPN PM. This document specifies the framework and mechanisms for the application of L3VPN PM.
3. BGP Extension For L3VPN Performance Monitoring
