Abstract
Software-Defined Networking (SDN) promises to enable vigorous innovation, through separation of the control plane from the data plane, and to enable novel forms of network management, through a controller that uses a global view to make globally-valid decisions. The design of SDN controllers creates novel challenges; much previous work has focussed on making them scalable, reliable, and efficient.
We argue that, to control a realistic network, we do not want one monolithic SDN controller. Instead, we want to compose the effects of many controller modules managing different aspects of the network, which may be competing for resources. Each module will try to optimize one or more objectives; we address the challenge of how to coordinate between these modules to optimize an overall objective function. Our framework design, Corybantic, focusses on achieving both modular decomposition and maximizing the overall value delivered by the controller's decisions.
Biography
Jeff Mogul is a Fellow at HP Labs, doing research primarily on computer networks and operating systems issues for enterprise and cloud computer systems; previously, he worked at the DEC/Compaq Western Research Lab. He received his PhD from Stanford in 1979, and is an ACM Fellow. Jeff is the author or co-author of several Internet Standards; he contributed extensively to the HTTP/1.1 specification. He was an associate editor of Internetworking: Research and Experience, and has been the chair or co-chair of a variety of conferences and workshops, including SIGCOMM, OSDI, and ANCS. He is currently co-chairing NSDI 2013.
