Known subclasses

Name	Type	Description
DispatchProtocolInd	class	This indication specifies the sending protocol of the message or packet when it's sent from one protocol module to another using the MessageDispatcher.
DispatchProtocolReq	class	This request determines the destination protocol of the message or packet when it's sent from one protocol module to another using the MessageDispatcher.
MacProtocolInd	class	This indication specifies the mac protocol that was used to receive the packet. It may be present from the mac protocol to the application.
MacProtocolReq	class	This request determines the mac protocol that should be used to send the packet. It may be present from the application to the mac protocol and from the mac protocol to the physical layer.
NetworkProtocolInd	class	This indication specifies the network protocol that was used to receive the packet. It may be present from the network protocol to the application.
NetworkProtocolReq	class	This request determines the network protocol that should be used to send the packet. It may be present from the application to the network protocol and from the network protocol to the physical layer.
PacketProtocolTag	class	This tag specifies the protocol of the packet.
TransportProtocolInd	class	This indication specifies the transport protocol that was used to receive the packet. It may be present from the transport protocol to the application and from the transport protocol to the physical layer.
TransportProtocolReq	class	This request determines the transport protocol that should be used to send the packet. It may be present from the application to the transport protocol.
