faucet.faucet module

OSKenApp shim between Ryu and Valve.

class faucet.faucet.EventFaucetAdvertise[source]

Bases: EventBase

Event used to trigger periodic network advertisements (eg IPv6 RAs).

class faucet.faucet.EventFaucetEventSockHeartbeat[source]

Bases: EventBase

Event used to trigger periodic events on event sock, causing it to raise an exception if conn is broken.

class faucet.faucet.EventFaucetFastAdvertise[source]

Bases: EventBase

Event used to trigger periodic fast network advertisements (eg LACP).

class faucet.faucet.EventFaucetFastStateExpire[source]

Bases: EventBase

Event used to trigger fast expiration of state in controller.

class faucet.faucet.EventFaucetMaintainStackRoot[source]

Bases: EventBase

Event used to maintain stack root.

class faucet.faucet.EventFaucetMetricUpdate[source]

Bases: EventBase

Event used to trigger update of metrics.

class faucet.faucet.EventFaucetResolveGateways[source]

Bases: EventBase

Event used to trigger gateway re/resolution.

class faucet.faucet.EventFaucetStateExpire[source]

Bases: EventBase

Event used to trigger expiration of state in controller.

class faucet.faucet.Faucet(*args, **kwargs)[source]

Bases: OSKenAppBase

A OSKenApp that implements an L2/L3 learning VLAN switch.

Valve provides the switch implementation; this is a shim for the Ryu event handling framework to interface with Valve.
