1. A method for setting a timing interval between attempts to establish a label switched path (LSP) between an ingress node and an egress node of a communication network, comprising:
- a) defining a unique identification (LSP ID) for said LSP and establishing a signalling link between said ingress and egress nodes;
b) at said ingress node, monitoring said signalling link to detect a message indicating that said LSP has been established;
c) initiating from said ingress node a new attempt to establish said LSP after a retry time interval from a previous attempt, if said ingress node did not receive said message indicating that said LSP has been established from said signalling link; and
, d) repeating step c) after a different retry time interval, said different retry time interval being greater than said retry time interval.

Abstract
A method of timing an attempt to establish a connection path between a first and second node in a communications network is provided. The method initiates the attempt to establish a connection path after a period of time has elapsed wherein the period of time is greater than another period of time which had previously elapsed between two previous attempts, if any, to establish the connection.

9. A method for establishing label switched paths (LSPs) across a communication network, comprising:
-
i) maintaining at a first node of said communication network a list of records including all said LSPs to be established from said first node;
ii) selecting from said list of records a first record for a particular LSP of said LSPs to be established, and establishing a first signalling link between said first node and an egress node for said particular LSP;
iii) monitoring at said first node for messages indicating that said particular LSP has been established; and
,iv) if said particular LSP has been established, marking said first record as being successful. - View Dependent Claims (10, 11, 12, 13)
