Claims:WE CLAIM
1. A method for modifying per hop behavior of one or more Expedited Forwarding (EF) packets for a session in a communication network, the method comprising:
determining, by an escalated expedited forwarding system, at least one of latency, jitter and average jitter associated with the one or more EF packets for the session;
marking, by the escalated expedited forwarding system, one or more EF packets based on the at least one of latency, jitter and average jitter; and
modifying, by the escalated expedited forwarding system, the per hop behavior of the one or more marked EF packets.
2. The method of claim 1 wherein determining at least one of latency, jitter and average jitter associated with the one or more EF packets is based on monitoring of round trip time (RTT) associated with the one or more EF packets for the session for a pre-configured time interval;

3. The method of claim 1, wherein latency is determined based on comparison of average of the monitored RTT and a preconfigured latency threshold.

4. The method of claim 1, wherein jitter is determined based on comparison of difference of maximum monitored RTT and minimum monitored RTT with a preconfigured jitter threshold.

5. The method of claim 1, wherein the average jitter is determined based on comparison of difference between current RTT average and previous RTT average with a preconfigured average-jitter threshold.

6. The method of claim 1 wherein marking the one or more EF packets further comprises changing IP header type of service of the one or more EF packets.

7. The method of claim 1 wherein the modifying the per hop behavior of the one or more marked EF packets further comprises :
sequencing the one or more marked EF packets of the session to increase speed, throughput and reliability of the one or more marked-EF packets; and
erasing the one or more marked EF packets, if ingress queue for the one or more marked EF packets exceed a pre-defined value.

8. An escalated expedited forwarding system, for modifying per hop behavior of one or more Expedited Forwarding (EF) packets for a session in a communication network , the system comprising:

a memory;
a processor coupled to the memory storing processor executable instructions which when executed by the processor causes the processor to perform operations comprising:
determining at least one of latency, jitter and average jitter associated with the one or more EF packets for the session ;
marking one or more EF packets in response to detecting the congestion ; and
modifying the per hop behavior of the one or more EF packets based on the marking.
9. The system of claim 8 wherein determining at least one of latency, jitter and average jitter associated with the one or more EF packets is based on monitoring of round trip time (RTT) associated with the one or more EF packets for the session for a pre-configured time interval.

10. The system of claim 8, wherein latency is determined based on comparison of of the monitored RTT-average and a preconfigured latency threshold RTT.

11. The system of claim 8, wherein jitter is determined based on comparison of difference of maximum monitored RTT and minimum monitored RTT with a preconfigured jitter threshold.

12. The system of claim 8, wherein the average jitter is determined based on comparison of difference between current RTT average and previous RTT average with a preconfigured average jitter threshold.

13. The system of claim 8 wherein marking the one or more EF packets further comprises changing IP header type of service of the one or more EF packets.

14. The system of claim 8 wherein modifying the per hop behavior of the one or more EF packets further comprises:
sequencing the marked one or more EF packets of the session to increase speed, throughput and reliability of the one or more marked-EF packets; and
erasing the marked one or more EP packets, if ingress queue for the marked one or more EP packets exceed a pre-defined value.
