Tesseract: a 4D network control plane

摘要: We present Tesseract, an experimental system that enables the direct control of a computer network is under single administrative domain. Tesseract's design based on 4D architecture, which advocates decomposition plane into decision, dissemination, discovery, and data planes. Tesseract provides two primary abstract services to enable control: dissemination service carries opaque information fromthe decision element nodes in network, node configuration interface for command carry out desired policies. Tesseract designed easy innovation. The neighbor services, are agnostic policies, only distributed functions implemented switch nodes. A variety policies can be outside without need introducing new protocols. also minimizes manual configurations reduce human errors. evaluate responsiveness robustness when applied backbone enterprise topologies Emulab environment. find resilient component failures. Its intra-domain routing sufficiently scalable handle thousand Moreover, we demonstrate flexibility by showing its application joint packet forwarding policy filtering IP networks, link-cost driven Ethernet forwarding.
