Managing network forwarding configurations using algorithmic policies

摘要

Techniques for managing forwarding configurations in a data communications network include accessing, at the at least one controller, an algorithmic policy defined by a user comprising one or more programs written in a general-purpose programming language other than a language of data forwarding element forwarding rules, which algorithmic policy in particular defines a packet-processing function specifying how data packets are to be processed through the data communications network via the at least one controller. A forwarding configuration for at least one data forwarding element in the data communications network may be derived from the user-defined packet-processing policy, and may be applied to the at least one data forwarding element.
