Logger; Service Manager - Alcatel-Lucent 7450 Manual

Logger

LDP uses the logger interface to generate debug information relating to session setup and
teardown, LDP events, label exchanges, and packet dumps. Per-session tracing can be performed.

Service Manager

All interaction occurs between LDP and the service manager, since LDP is used primarily to
exchange labels for Layer 2 services. In this context, the service manager informs LDP when an
LDP session is to be set up or torn down, and when labels are to be exchanged or withdrawn. In
turn, LDP informs service manager of relevant LDP events, such as connection setups and
failures, timeouts, labels signaled/withdrawn.
