| 摘要 |
The invention relates to a low-effort method for monitoring the availability of connections in MPLS networks, according to which specially configured MPLS-OAM packets are defined and are periodically inserted into the traffic flow of user data packets at the source of a connection or a partial section of a connection, said specially configured MPLS-OAM packets being distinguishable from other MPLS-OAM packets and the MPLS packets carrying user data by means of a special mark or identifier. The specially configured MPLS-OAM packets are periodically checked for arrival thereof at the acceptor of the connection or the partial section of the connection. The connection is declared unavailable if none of said packets have been received within a predefined period of time. |
