Abstract:
Network congestion in the current Internet usually causes packet loss and prolonged packet delivery latency due to retransmission. Qualitative Communication as one of the major features in New IP reduces the network layer operation from the packet level to much smaller granularity, namely packet wash. This paper illustrates such possibility by using Constrained Application Protocol (CoAP) as an example, which would be of wide usage owing to the thriving of Internet of Things (IoT) applications. The paper proposes two aspects of packet wash actions to CoAP packet: (1) header compression facilitated by cross-layer design; (2) partial packet dropping empowered by payload chunkification and New IP metadata. The paper elaborates on the detailed mechanisms, which provide many benefits with very slim overhead.
