METHOD FOR THE PROTECTION SWITCHING OF TRANSMISSION DEVICES IN MPLS NETWORKS

摘要

In prior art, one of the problems of equivalent switching MPLS packets is th at the transmission of MPLS packets is defined unidirectionally. The inventive method provides a solution to the problem in the form of a configuration whi ch allows for bidirectional and 1:n unidirectional transmission (requiring a reverse LAN channel). Equivalent switching operations in the case of an erro r occurring when a working entity fails are administered in an efficient manne r according to priority criteria and MPLS link information
