摘要： An access node (e.g., DSLAM) and method for optimizing the distribution of a multicast stream within a hybrid PPPoE/IPoE broadband assess network are described herein. In the preferred embodiment, the DSLAM snoops upstream IGMP messages encapsulated within PPPoE frames, and forwards them transparently towards a BRAS (located in an Ethernet aggregation network). In addition, the DSLAM duplicates the IGMP message and sends the duplicated IGMP message encapsulated within IPoE frames towards the standard Ethernet switches (located in the Ethernet aggregation network). The IPoE encapsulated IGMP message can be snooped by the standard Ethernet switches. This functionality of the DSLAM ensures the optimal multicast distribution by the Ethernet aggregation network.
摘要翻译： 本文描述了用于优化混合PPPoE / IPoE宽带接入网络内的多播流的分布的接入节点（例如，DSLAM）和方法。 在优选实施例中，DSLAM监听封装在PPPoE帧内的上游IGMP消息，并向BRAS（位于以太网聚合网络中）透明地转发。 此外，DSLAM复制IGMP消息，并将封装在IPoE帧内的复制IGMP消息发送到标准以太网交换机（位于以太网聚合网络中）。 IPoE封装的IGMP消息可以被标准的以太网交换机窥探。 DSLAM的这种功能确保了以太网聚合网络的最佳组播分配。

摘要： A method and Access Network Node for handling dissimilar protocols when a Host accesses a Broadband Network. The Access Network Node includes a protocol converter for interworking between the Neighbor Discovery (ND) protocol and the Dynamic Host Configuration Protocol (DHCP). When an ND Router Solicitation message is received from a Host that does not support DHCP, the converter converts the ND message to a DHCP Solicit message and forwards it to a Broadband Network Gateway (BNG) together with a port ID. When the Access Network Node receives a DHCP Reply message from the BNG destined for the same Host, the converter converts the DHCP Reply message to an ND Router Advertisement message before sending it to the Host.

摘要： A broadband access node and method for controlling access by end users to services over communication channels. A resource admission control mechanism includes a first memory for storing information about a currently available transmission capacity on an uplink channel, a second memory for storing information about a currently available transmission capacity on a downlink subscriber line; and a third memory for storing information about a currently available maximum performance of the access node. A fourth memory stores service-related information regarding the capacity and performance service requirements of respective services. A processor calculates whether the service requirements of a requested service fulfill given conditions in relation to currently available uplink/downlink capacity and currently available performance capability of the access node. Requests that fulfill the given conditions are granted while requests that do not fulfill the conditions are rejected.

摘要： A system and method for mapping original Media Access Control (MAC) addresses to unique locally administered virtual MAC addresses in an Ethernet network. A first field of the address may include a domain for the address, and a second field may indicate that the address is a locally administered MAC address. A third field of the address may include an index indicating a number of virtual MAC addresses for each user. Fourth and fifth fields of the address may include a Network Element ID (NE ID) for uniquely identifying a given access node in a given domain, and a Port ID for uniquely identifying an end-user port at the given access node. The system may be implemented in an access node or in a network emulator, which generates unique locally administered MAC addresses for all of the nodes in the Ethernet network for performing emulations of the network.

摘要： An access node connected to end-users, routers, and a DHCP-server. The end-user defines desired services provided via the routers. A purpose is to automatically provide simultaneous access to services via two or more of the routers, although the end-user simultaneously handles only one router. The connections are secure. The end-user requests one of the services. The access node identifies the end-user and sends a corresponding request to the DHCP-server, which dynamically allocates addresses to the end-user and to all the routers for the desired services. The access node snoops the addresses in a DHCP option message from the DHCP-server, resolves the router addresses, stores IP router addresses and IP MAC addresses in a memory and sets MAC addresses in MAC filters. An option reply with one router is sent to the end-user, which after request for one service, reaches all the services stored in the memory.
