This paper is providing a new application level reliability mechanisms for time sensitive lightweight signaling between nodes at the edge of an access network. Such signaling may carry sub payloads with varying degree of reliability and hence cannot easily employ a traditional reliable transport protocol such as TCP. The reliability mechanism described in this paper, provides a large degree of flexibility in the degree of reliability. Correct sub payloads can be extracted from the packet, while allowing retransmission requests (the number of retransmissions can be pre-determined for each sub payload type). Also in cases the originally retransmitted data is no longer valid, updates can be requested as well.
