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： 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： Embodiments of the present invention relate to a method and system for providing resource admission control (RAC) of digital media streams between a media server and terminals in a customer premises network. According to an embodiment of the present invention, the method includes receiving from a terminal, a resource request comprising a resource requirement pertaining to a unicast digital media stream request, determining if transmission resources are available for the requested unicast digital media stream based on the resource request, and if so, transmitting a resource availability message pertaining to the unicast digital media stream request to the media server in order for the media server to begin streaming the requested unicast media stream towards the terminal. Embodiments of the present invention further relate to an access node, a terminal and a media server.

摘要： A method of operating an Access Node (AN) includes polling a client by periodically causing a query message to be sent to each client that has established a communication link with the AN, and listening for a response message from the client. In one aspect, if the response contains a valid link-local address as the source address of the client, but for which the AN has no record of the Media Access Control (MAC)-Internet Protocol (IP) address-relation, then the AN performs a Duplicate Address Detection (DAD) operation towards the IP network. If no collision is detected enforces the MAC-IP address relation for the link-local address of the client. In another aspect, if the client does not respond, and the AN has a record of an existing removable MAC-IP address-relation for the client, the AN removes that existing removable address-relation.
摘要翻译：操作接入节点（AN）的方法包括通过周期性地使查询消息被发送到已经建立与AN的通信链路的每个客户端并且从客户端收听响应消息来轮询客户端。在一个方面，如果响应包含有效的链路本地地址作为客户端的源地址，但是AN没有媒体访问控制（MAC） - 互联网协议（IP）地址关系的记录，则 AN对IP网络执行重复地址检测（DAD）操作。如果没有检测到冲突，则强制执行客户端链路本地地址的MAC-IP地址关系。在另一方面，如果客户端没有响应，并且AN具有用于客户端的现有可移动MAC-IP地址关系的记录，则AN去除该现有的可移动地址关系。
