OpenDaylight Summit 2016

The emergence of multi-table pipelining as a key feature of next-generation SDN datapath models requires tools to automate the usage of this feature, and the objective of Magellan is to achieve the goal: automate the usage of multi-table datapath from datapath-oblivious algorithmic SDN policies. Magellan introduces two modules: a table designer to automatically generate a pipeline specification, and a table populater to populate the tables, during both static analysis and at runtime. We will discuss the issues that we have encountered when implementing Magellan in OpenDaylight, in particular the issue of how to proactively explore a program to generate its full content. We will also discuss additional issues and seek feedback and collaboration from the community.
