Why Signal QOS In current implementations, QOS parameters are manually configured at the PE devices. This restricts configurations where QOS parameters are dynamically determined for some Attachment Circuits – ex. ATM SVCs As the number of PWs grow, setting consistent QOS parameters at PE devices becomes cumbersome With the use of auto-discovery of PW endpoints, admitting PW connections based on available resources is key In Multi-segment PWs, each switching PE must know what the QOS requirements are in order to determine its eligibility as a suitable PW switching node Need for QOS signaling for PW is undisputable |
