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.
