摘要： A method for communicating packets in a network environment is provided that includes receiving a packet at a network element and identifying a sequence number included in the packet that correlates to awareness information associated with one or more adjacent network elements. A table included in the network element may be updated in order to account for the awareness information included within the packet that has not been accounted for by the network element. In cases where the awareness information included in the packet has already been accounted for, the packet may be ignored.

摘要： An invention is disclosed that optimizes resource management within a Packet Data Serving Node PDSN. This is accomplished through the modification of a Authentication, Authorisation and Accounting (AAA) server. Specifically, when a node (e.g., mobile node) is authenticated by a AAA server in response to a request by a target PDSN to which the node has roamed, the AAA server may send a disconnect request message to a source PDSN indicating that the node has moved from the source PDSN. In this manner, the source PDSN is notified that it should terminate its session with the node and release resources associated with the session (e.g., Point-to-Point Protocol session). The source PDSN may then send a message to the AAA server indicating whether the session was successfully terminated and whether the resources associated with that session were released).
摘要翻译：公开了一种优化分组数据服务节点PDSN内的资源管理的发明。这通过修改认证，授权和计费（AAA）服务器来实现。具体地说，当节点（例如移动节点）由AAA服务器响应于节点所漫游的目标PDSN的请求进行认证时，AAA服务器可以向源PDSN发送断开请求消息，指示该节点已经从源PDSN移动。以这种方式，通知源PDSN应该终止与节点的会话并释放与会话相关联的资源（例如，点到点协议会话）。源PDSN然后可以向AAA服务器发送消息，指示会话是否被成功终止以及与该会话相关联的资源是否被释放）。

摘要： An apparatus for communicating packets in a network environment is provided that includes a first network element that includes a first neighbor list, the first network element being coupled to a second network element and a third network element. The first network element is operable to receive a second neighbor list from the second network element and a third neighbor list from the third network element. The first network element is further operable to determine one or more overlaps provided by the second and third neighbor lists when compared to the first neighbor list, the first network element relaying an update that it receives based on the one or more overlaps.

摘要： The present invention provides methods and apparatus for managing an IP address assigned to a Mobile Node. In one embodiment, the Mobile Node appends an extension to the registration request that is sent to its Home Agent, which indicates that the Mobile Node requests use of the IP address previously assigned to the Mobile Node for an additional period of time. When the Home Agent receives the registration request, it indicates whether a lease on the IP address previously assigned to the Mobile Node has been granted by the Home Agent for an additional period of time. In another embodiment, the Home Agent sends a first control message to determine whether the Mobile Node continues to use the IP address. The Home Agent then determines whether a second control message has been received in order to ascertain whether the Mobile Node continues to use the IP address previously assigned to the Mobile Node. The present invention is preferably performed when a Mobile Node returns to its home network, thereby enabling the Mobile Node to retain the IP address assigned to it.
摘要翻译：本发明提供了用于管理分配给移动节点的IP地址的方法和装置。在一个实施例中，移动节点将附加到发送到其归属代理的注册请求的扩展，其指示移动节点请求使用先前分配给移动节点的IP地址一段时间。当归属代理接收到注册请求时，它指示先前分配给移动节点的IP地址上的租约是否已由归属代理许可一段时间。在另一个实施例中，归属代理发送第一控制消息以确定移动节点是否继续使用IP地址。归属代理然后确定是否已经接收到第二控制消息以便确定移动节点是否继续使用先前分配给移动节点的IP地址。本发明优选地在移动节点返回到其归属网络时进行，从而使得移动节点能够保留分配给它的IP地址。
