Session establishment method and the label switch node in label switch network

摘要

The contiguity label switch node (11) the particular node (11) adding the information of the session identification which identifies the session which it should establish between to the message which is sent and received in between, the label switch network of MPLS and the like in, with label distribution protocol (1), it does sending and receiving the message, the particular node (11), the identical contiguity label switch node (11) it establishes the plural sessions which are used in the identical label space between respectively, on the basis of the information of the above-mentioned session identification. Because of this, label switch network (1) you can expect the improvement of simplification, pliability improvement and conservative/operational/management efficiency etc of the design.
