Method and system for pre-reservation timer adaptation in PCE based networks
First Claim
1. A method for Pre-Reservation timer adaptation in Path Computation Element (PCE) based networks, the method comprising:
- updating a status of a network using a protocol of a control plane of the network and in response to a path request from at least a path computation client (PCC) pre-reserving during a reserved period of time (Tres), by at least one path computation element (PCE), a plurality of network resources in at least one traffic engineering database (TED) of the at least one PCE,wherein the method further comprises dynamically modifying by a timer policy the reserved period of time (Tres) by at least using information data regarding a delay of the control plane.

Abstract
The method updating the status of a network by means of a protocol of the control plane of said network and in response to a path request from at least a path computation client (PCC) pre-reserving during a reserved period of time (Tres), by at least one path computation element (PCE), a plurality of network resources in at least one traffic engineering database (TED) of the at least one PCE. The method dynamically modifying by a timer policy said reserved period of time (Tres) by at least using information data regarding the delay of said control plane.
The system of the invention is adapted to implement the method of the invention.

12. A system for Pre-Reservation timer adaptation in Path Computation Element (PCE) based networks, the system comprising:
-
an updater configured to update a status of a network; at least one path computation element (PCE) configured to pre-reserve during a reserved period of time (Tres), in response to a path request from at least a path computation client (PCC), a plurality of network resources in at least one traffic engineering database (TED) of the at least one PCE; and a module including a PCE Communication Protocol (PCEP) decoder, a delay monitor, and an Internal NNI (I-NNI) decoder, wherein the module further comprises; a stolen lambda correlator module configured to detect if there are stolen lambda blocks; and a reserved period detector module configured to measure the reserved period of time, wherein the module is configured to provide a timer policy configured to dynamically modify the reserved period of time (Tres) by at least using information data regarding a delay of the control plane. - View Dependent Claims (13, 14, 15, 16, 17, 18)
