On Ethernet networks, MAC addresses are used to identify.The switch builds the MAC address table by examining the source MAC address of incoming frames. This outgoing interface could be that of the originating node, or of an intermediate router between the originating node and the destination node.ASSISTED WIRELESS TRANSMIT/RECEIVE UNIT PAGING AND CALL SESSION ROUTINGThis IP address will get the packet to the network location of the destination device. The source MAC address will be the MAC address of the outgoing interface which sent the frame. Ethernet relies on a destination MAC address for frame delivery.The MAC address of the outgoing interface should be the new source MAC address for the Ethernet frame. Ethernet frame is encapsulated in IP + UDP + VXLAN headers.SUBSCRIBER INFORMATION MANAGEMENT SYSTEM AND METHOD FOR MOBILE COMMUNICATION SERVICE SYSTEMThis address should be the new destination MAC address for the Ethernet frame. Do not use any agent stuff. This function learns the MAC address of the device and set init. If a switch has no entries in the MAC address table or if the destination MAC address is not in the switch table, the switch will forward the frame out all ports.The method of claim 1, wherein the OAM frame further comprises an indication of the type of OAM function to be performed.3. A method of implementing Ethernet OAM at an intermediate node in a Provider Bridged Transport (PBT) network, the method comprising the steps of: receiving by an intermediate network element on a PBT trunk in an Ethernet network a OAM frame addressed to an endpoint of the PBT trunk but containing an indicia that the OAM frame is intended to be used to perform an intermediate node OAM function and generating a reply message by the intermediate node based on information contained within the OAM frame.2.

The method of claim 1, wherein the intermediate node maintains correlation information between the PBT trunk and a reverse PBT trunk, wherein reply message is a reply OAM frame, and wherein the method further comprises the step of transmitting the reply OAM frame over the reverse PBT trunk.9. The method of claim 6, wherein the reverse trunk information comprises a VLAN ID of the reverse PBT trunk, wherein reply message is a reply OAM frame, and wherein the method further comprises the step of transmitting the reply OAM frame over the reverse PBT trunk.8. The method of claim 1, wherein the intermediate node doesn't maintain correlation information between the PBT trunk and a reverse PBT trunk, and wherein the OAM frame contains reverse trunk information to enable the intermediate node to generate the reply message for transmission over the reverse PBT trunk.7. The method of claim 4, wherein the step of determining comprises evaluating a target destination address field of the OAM frame to determine if the OAM frame contains a MAC address of the intermediate node in the target destination address field.6. The method of claim 1, further comprising the step of determining, by the intermediate node, whether a response is required to the OAM frame, and wherein the step of generating a reply message is performed if a response is required.5.
![]() ![]() 31, 2006, entitled “OAM For Differential Forwarding in Address Based Networks,” the content of which is hereby incorporated herein by reference. Provisional Application No. The Ethernet frame of claim 19, further comprising a plurality of fields that may be used to generate the reply message, the plurality of fields comprise at least a first field containing a destination MAC address of a reply PBT trunk and a second field containing a reverse VLAN ID associated with the reply PBT trunk.This application is related to and claims the benefit of U.S. An Ethernet frame, comprising: an Ethernet header containing a destination MAC address (DA) and a VLAN Identifier (VID) configured to enable the Ethernet frame to be transported along a Provider Bridged Transport (PBT) trunk through an Ethernet network, the PBT trunk being defined by installing forwarding state associated with the DA/VID in network elements on the Ethernet network along a path through the Ethernet network and at least one of: an Ethertype value indicating that the Ethernet frame is an OAM frame an OpCode value or a combination of an organization specific OpCode value and one or more sub-field values indicating that the Ethernet frame is an OAM frame and a TLV value or a combination of an organization specific TLV value and one or more sub-field values indicating that the Ethernet frame is an OAM frame.20. Mac windows emulator dns issueChanges in the Ethernet standard have enabled Ethernet to evolve to the point where Ethernet is now being considered for larger networks such as metropolitan area and wide area networks. Originally Ethernet was used on local area networks, such as enterprise networks in businesses and on college campuses. Different protocols are used to govern different aspects of communications on a network, such as how signals should be formed for transmission between network elements, various aspects of what the protocol data units should look like, how packets should be handled or routed through the network by the network elements, and how information associated with routing information should be exchanged between the network elements.Ethernet is a well known networking protocol that has been defined by the Institute of Electrical and Electronics Engineers (IEEE) as standard 802. A particular Protocol Data Unit (PDU) may be handled by multiple network elements and cross multiple communication links as it travels across the network.The various network elements on the communication network communicate with each other using predefined sets of rules, referred to herein as protocols. These devices will be referred to herein as “network elements.” Data is communicated through the data communication network by passing protocol data units, such as Internet Protocol (IP) packets, Ethernet Frames, data cells, segments, or other logical associations of bits/bytes of data, between the network elements by utilizing one or more communication links between the devices.
