Pathetic: Path Frenetic

Pathetic is a language for SDN forwarding policies specified at the path-level. For example, a policy can require that all SSH traffic traverses a specific IDS box:

TcpDstPort = 22 => [*.IDS.*]

For more details, see the FatTire paper, which builds upon Pathetic: http://www.cs.cornell.edu/~reitblatt/papers/fault-tolerance-hotsdn13.pdf
