Example for Configuring Single-ended SLM in VLL Networking
This section provides an example for configuring single-ended synthetic loss measurement
(SLM) in virtual leased line (VLL) networking.
Networking Requirements
As networks rapidly develop and applications diversify, various value-added services, such as
Internet Protocol television (IPTV), video conferencing, and voice over Internet Protocol (VoIP),
are more widely used than ever before. Any link connectivity fault or network performance
deterioration directly affects service quality on a live network, making performance monitoring
on the pipes that transmit these services absolutely essential.
On the point-to-multipoint network shown in
performance statistics about LM on the link between PE1 and PE3. To monitor network
performance in real time, the carrier can configure single-ended SLM on the VLL network. This
configuration allows the carrier to immediately adjust the network in case of voice quality
deterioration.
