Detailed Description

Flow Table of active flows.

This class stores all active flows created on a given datapath element. Class cflowentry defines the container for an active flow. Class cflowtable defines two groups of methods:

Static methods on CRUD operations for instances of class cflowtable
Methods on CRUD operations for instances of class cflowentry in a cflowtable instance

Member Function Documentation

cflowentry& rofl::examples::ethswctld::cflowtable::add_flow_entry	(	const rofl::caddress_ll &	src,
		const rofl::caddress_ll &	dst,
		uint32_t	portno
	)

inline

Returns reference to empty cflowentry instance for given hardware address.

Creates a new cflowentry instance or resets an already existing one for the given identifier.

Parameters

src	ethernet hardware address for source station of flow
dst	ethernet hardware address for destination station of flow
portno	outgoing port for this flow

Exceptions

eFlowInval hardware address validation failed

static cflowtable& rofl::examples::ethswctld::cflowtable::add_flowtable ( const rofl::cdptid & dptid )

inlinestatic

Returns reference to new or existing and resetted cflowtable instance.

This method creates a new or resets an existing instance of class cflowtable for the given datapath handle.

Parameters

dptid rofl-common's internal handle for datapath element

void rofl::examples::ethswctld::cflowtable::drop_flow_entry	(	const rofl::caddress_ll &	src,
		const rofl::caddress_ll &	dst
	)

inline

Removes an existing cflowentry for given source and destination hardware address.

Parameters

src	ethernet hardware address for source station of flow
dst	ethernet hardware address for destination station of flow

static void rofl::examples::ethswctld::cflowtable::drop_flowtable ( const rofl::cdptid & dptid )

inlinestatic

Removes an existing cflowtable instance.

Parameters

dptid rofl-common's internal handle for datapath element

const cflowentry& rofl::examples::ethswctld::cflowtable::get_flow_entry	(	const rofl::caddress_ll &	src,
		const rofl::caddress_ll &	dst
	)		const

inline

Returns const reference to existing cflowentry instance for given hardware address.

Returns reference to existing cflowentry for given identifier or throw exception, if none exists.

Parameters

src	ethernet hardware address for source station of flow
dst	ethernet hardware address for destination station of flow

Exceptions

eFlowInval	hardware address validation failed
eFlowNotFound	flow destination address not found

static const cflowtable& rofl::examples::ethswctld::cflowtable::get_flowtable ( const rofl::cdptid & dptid )

inlinestatic

Returns const reference to existing cflowtable instance or throws exception.

This method returns a const reference to an existing cflowtable instance. If no instance for the given identifier is found, an exception of type eFibNotFound is thrown.

Parameters

dptid rofl-common's internal handle for datapath element

Exceptions

eFibNotFound

bool rofl::examples::ethswctld::cflowtable::has_flow_entry	(	const rofl::caddress_ll &	src,
		const rofl::caddress_ll &	dst
	)		const

inline

Checks whether a cflowentry exists for given source and destination hardware address.

Parameters

src	ethernet hardware address for source station of flow
dst	ethernet hardware address for destination station of flow

static bool rofl::examples::ethswctld::cflowtable::has_flowtable ( const rofl::cdptid & dptid )

inlinestatic

Checks existence of cflowtable for given identifier.

Parameters

dptid rofl-common's internal handle for datapath element

cflowentry& rofl::examples::ethswctld::cflowtable::set_flow_entry	(	const rofl::caddress_ll &	src,
		const rofl::caddress_ll &	dst,
		uint32_t	portno
	)

inline

Returns reference to existing cflowentry instance for given hardware address.

Returns reference to existing cflowentry for given identifier or creates new one if non exists yet.

Parameters

src	ethernet hardware address for source station of flow
dst	ethernet hardware address for destination station of flow
portno	outgoing port for this flow

Exceptions

eFlowInval hardware address validation failed

cflowentry& rofl::examples::ethswctld::cflowtable::set_flow_entry	(	const rofl::caddress_ll &	src,
		const rofl::caddress_ll &	dst
	)

inline

Returns reference to existing cflowentry instance for given hardware address.

Returns reference to existing cflowentry for given identifier or throw exception, if none exists.

Parameters

src	ethernet hardware address for source station of flow
dst	ethernet hardware address for destination station of flow

Exceptions

eFlowInval	hardware address validation failed
eFlowNotFound	flow destination address not found

static cflowtable& rofl::examples::ethswctld::cflowtable::set_flowtable ( const rofl::cdptid & dptid )

inlinestatic

Returns reference to existing cflowtable instance or creates a new empty one.

This method returns a reference to an existing cflowtable instance. If no instance for the given identifier is found, a new instance is created.

Parameters

dptid rofl-common's internal handle for datapath element
