Detailed Description

Interface for L2 mesh routing protocol and mesh point communication.

Every mesh routing protocol must implement this interface. Each mesh point (MeshPointDevice) is supposed to know single L2RoutingProtocol to work with, see MeshPointDevice::SetRoutingProtocol ().

This interface is similar to ipv4 routing protocol base class.

Member Typedef Documentation

◆ RouteReplyCallback

typedef Callback<void, bool, Ptr<Packet>, Mac48Address, Mac48Address, uint16_t, uint32_t > ns3::MeshL2RoutingProtocol::RouteReplyCallback

Callback to be invoked when route discovery procedure is completed.

Parameters

flag	indicating whether a route was actually found and all needed information is added to the packet successfully
packet	for which the route was resolved. All routing information for MAC layer must be stored in proper tags (like in case of HWMP, when WifiMacHeader needs address of next hop), or must be added as a packet header (if MAC does not need any additional information). So, the packet is returned back to MeshPointDevice looks like a pure packet with ethernet header (i.e data + src +dst + protocol). The only special information addressed to MeshPointDevice is an outcoming interface ID.
src	source address of the packet
dst	destination address of the packet
protocol	ethernet 'Protocol' field, needed to form a proper MAC-layer header
uint32_t	outcoming interface to use or 0xffffffff if packet should be sent by ALL interfaces

◆ GetMeshPoint()

Ptr< MeshPointDevice > ns3::MeshL2RoutingProtocol::GetMeshPoint ( ) const

Each mesh protocol must be installed on the mesh point to work.

Returns: the mesh point device

◆ GetTypeId()

TypeId ns3::MeshL2RoutingProtocol::GetTypeId ( )

static

Get the type ID.

Returns: the object TypeId

Here is the call graph for this function:

◆ RemoveRoutingStuff()

virtual bool ns3::MeshL2RoutingProtocol::RemoveRoutingStuff	(	uint32_t	fromIface,
		const Mac48Address	source,
		const Mac48Address	destination,
		Ptr< Packet >	packet,
		uint16_t &	protocolType )

pure virtual

When packet is ready to go to upper layer, protocol must remove all its information: tags, header, etc.

So, MeshPointDevice must call this method when passing a packet to upper layer.

Returns: true if packet shall not be dropped, false otherwise.

Parameters

fromIface	the incoming interface of the packet
source	source address
destination	destination address
packet	the packet to be handled
protocolType	protocol ID, needed to form a proper MAC-layer header

Attention: protocol type is passed by reference, because may be changed

Implemented in ns3::dot11s::HwmpProtocol, and ns3::flame::FlameProtocol.

◆ RequestRoute()

virtual bool ns3::MeshL2RoutingProtocol::RequestRoute	(	uint32_t	sourceIface,
		const Mac48Address	source,
		const Mac48Address	destination,
		Ptr< const Packet >	packet,
		uint16_t	protocolType,
		RouteReplyCallback	routeReply )

pure virtual

Request routing information, all packets must go through this request.

Note that route discovery works async. – RequestRoute returns immediately, while reply callback will be called when routing information will be available.

Returns: true if valid route is already known

Parameters

sourceIface	the incoming interface of the packet
source	source address
destination	destination address
packet	the packet to be resolved (needed the whole packet, because routing information is added as tags or headers). The packet will be returned to reply callback.
protocolType	protocol ID, needed to form a proper MAC-layer header
routeReply	callback to be invoked after route discovery procedure, supposed to really send packet using routing information.

Implemented in ns3::dot11s::HwmpProtocol, and ns3::flame::FlameProtocol.

◆ SetMeshPoint()

void ns3::MeshL2RoutingProtocol::SetMeshPoint ( Ptr< MeshPointDevice > mp )

Set host mesh point, analog of SetNode (...) methods for upper layer protocols.

Parameters

mp	the mesh point device
