Hop-by-hop TCP communication as a network function - A proof-of-concept implementation
MetadataVis full innførsel
Techniques for enabling resilient network communication over less-than-optimal communication links were studied. A testbed for low-level networkbehavior and link characteristic emulation was created using QEMU-virtualized GNU/Linux nodes, TAP devices and the netem Linux trafficcontrol facilities. A proof-of-concept implementation, of configurationless,transparent hop-by-hop TCP communication as a network function was developedin C, using the Data Plane Development Kit (DPDK) in combinationwith the Transport Layer Development Kit (TLDK). Experiments wereperformed to analyze the behaviour, efficiency and benefit of the proof-of-concept implementation.
