Abstract
Various exemplary embodiments relate to a method and related network node including one or more of the following: maintaining a line card activity number at each line card in the node; receiving a first packet belonging to a flow; storing, at each line card, a flow record in a line card context identifier storage, wherein the flow record contains a flow activity number being initially set equal to a current value of the line card activity number; detecting, by the second line card, a change in designation to active and changing the value of the line card activity number maintained by the second line card; receiving a second packet belonging to the flow; and transmitting, to the decompressor node, an update packet including the flow context identifier and the flow identifying information, upon determining that the flow activity number is not equal to the updated line card activity number.
