IProtocolLayer

module interface

This module interface is implemented by all protocol layer modules that connect to a higher and to a lower protocol layer, both of which is optional.

Inheritance diagram

The following diagram shows inheritance relationships for this type. Unresolved types are missing from the diagram.

Implemented by

Name	Type	Description
BridgingLayer	compound module	This module provides various layer 2 services such as packet forwarding, interface selection, virtual LAN handling, stream handling.
DirectionReverserLayer	compound module	This module provides a layer that combines the decision for local delivery with the service of reversing the direction of an incoming packet to outgoing for packet forwarding.
Ieee8021dRelay	simple module	This modul forwards frames (EtherFrame) based on their destination MAC addresses to appropriate ports.
Ieee8021qLayer	compound module	(no description)
Ieee8021qProtocol	compound module	This module implements the IEEE 802.1Q protocol encapsulation/decapsulation. It also provides socket support so applications can use the protocol directly.
Ieee8021rLayer	compound module	(no description)
Ieee8021rProtocol	compound module	This module implements the IEEE 802.1r protocol encapsulation/decapsulation.
InterfaceRelayLayer	compound module	This module combines the interface MAC address learning from incoming packets with the outgoing interface selection for outgoing packets into a single layer.
MacRelayUnit	simple module	(no description)
Mpls	simple module	Implements the MPLS protocol.
OmittedProtocolLayer	compound module	This module implements the module given interface and can be used as an omitted optional module that removes itself from the module hierarchy during initialize.
StreamCoderLayer	compound module	This module combines a stream decoder and a stream encoder into a layer. For incoming packets the stream decoder determines the stream of the packet. For outgoing packets the stream encoder determines the VLAN id, etc. of the packet.
StreamFilterLayer	compound module	This module combines two packet filters into a protocol layer so that it can be used in a layered compound module. There are separate submodules for ingress and egress traffic, but in most cases only the ingress filter is used.
StreamIdentifierLayer	compound module	This module wraps a stream identifier into a protocol layer so that it can be used in a layered compound module.
StreamPolicyLayer	compound module	(no description)
StreamRelayLayer	compound module	This module combines a stream merger and a stream splitter module into a stream relay layer. For incoming packets the identified streams are merged by the stream merger. For outgoing packets the requested streams are split by the stream splitter.
VlanPolicyLayer	compound module	(no description)
