In case of a failure in a high speed packet switching network, the failure information provided by the multiplicity of resources is registered in the access nodes of the network. The failure information can be retrieved by the network management on request for fault correlation. A plurality of alarms flooding the network management when a failure occurs is thus avoided.

Fault correlation system and method in packet switching networks

In a packet switching network, voice packets are made to include an EC field whose contents indicates whether the corresponding packet is eligible for clipping if required in a node queue within the network. Should clipping of a non eligible packet be required, then another bit field would be set in the following packet on same link to limit any possible clipping of successive packets on same link.
