Claim Text:
1. A method of determining a reordering timer in a wireless communication network, comprising: receiving a data flow that includes a plurality of Radio Link Control (RLC) data packets at a network node during a waiting period; detecting, at an upper layer of a protocol stack, that at least one expected RLC data packet is not received during the waiting period; performing deep packet inspection of the data flow via a packet inspection node at the upper layer of the protocol stack to determine a reordering severity associated with the plurality of RLC data packets, wherein the reordering severity is estimated based on a reordering delay and a reordering block size associated with one or more out of sequence RLC data packets; estimating a reordering timer value based on the determined reordering severity and an application requirement of the data flow, wherein the application requirement comprises a maximum allowed data delay and a minimum allowed throughput; and instructing an access node to update a waiting period value to the estimated reordering timer value.
