Abstract:
1. A method of reducing delays associated with communication packets conveyed in a packetized network, comprising: providing a plurality of data frames belonging to different communication sessions conveyed along respective communication channels; providing protection data for protecting at least one of said plurality of data frames; and multiplexing one or more of said plurality of data frames into a second communication packet, wherein said second communication packet comprises protection data for protecting at least one first data frame that had already been transmitted in a first communication packet which transmission preceded a transmission of the second communication packet, the at least one first data frame belonging to a first communication session, wherein said protection data comprised in the second communication packet is attached to a second data frame, being at least one of the data frames multiplexed into the second communication packet, the second data frame belonging to a second communication session and having a second frame header that identifies the second communication session to which the second data frame belongs, wherein the protection data is operative to protect the at least one first data frame being at least one data frame transmitted in the first communication packet, the protection data being attached to the second data frame with a first frame header that identifies the first communication session to which the at least one first data frame belongs, and wherein the first communication session to which the at least one first data frame belongs is different from the second communication session to which the second data frame carrying the protection data for the at least one first data frame belongs.
