摘要： A network comprises a plurality of interconnected switches that implement a topology database synchronization technique in which each switch determines whether its topology database has already been transmitted to a neighboring switch when a new link is formed to the neighboring switch. When a new electrical connection is detected, the local switch determines whether any of its other ports have already been connected to the same neighboring switch. If no other port on the local switch has been connected to the neighboring switch, the local switch transmits its topology database to the neighboring switch. If the local switch determines that it has already been connected to the neighboring switch via another one of its ports, the local switch does not yet again copy of the database to the neighboring switch. Also, link state record updates are propagated via only one inter-switch link to a neighboring switch, not all possible links.
摘要翻译：网络包括实现拓扑数据库同步技术的多个互连交换机，其中当新邻接交换机形成新链路时，每个交换机确定其拓扑数据库是否已被发送到相邻交换机。当检测到新的电气连接时，本地交换机确定其他任何端口是否已经连接到相邻的交换机。如果本地交换机没有其他端口连接到相邻交换机，则本地交换机将其拓扑数据库发送到相邻交换机。如果本地交换机确定已经通过其他端口连接到相邻交换机，则本地交换机不再将数据库复制到相邻交换机。此外，链路状态记录更新仅通过一个交换机间链路传播到相邻交换机，而不是所有可能的链路。

摘要： A Voice over Internet Protocol (VoIP) gateway is provided which upon an extension call between VoIP terminals, optimizes transfer routes of data between the terminals. In setting a session for the extension call, the VoIP gateway converts IP addresses and ports of the originator's and recipient's terminals included in an invite message for session connection transmitted from one terminal of an internal private network of the VoIP gateway into internal IP addresses and internal ports to enable media data of the originator's and recipient's terminals to be directly transmitted without by way of a wide area network (WAN) module and a media server of the VoIP gateway, thereby effectively managing resources of the network system.
摘要翻译：提供了一种基于互联网协议语音（VoIP）网关，其在VoIP终端之间进行分机呼叫时优化终端之间的数据传输路由。在设置分机呼叫的会话期间，VoIP网关将VoIP呼叫的内部专用网络的一个终端发送的用于会话连接的邀请消息中包含的发起者和接收者终端的IP地址和端口转换为内部IP地址和内部IP地址端口，使得发起者和接收者的终端的媒体数据能够直接发送，而无需通过广域网（WAN）模块和VoIP网关的媒体服务器，从而有效地管理网络系统的资源。

摘要： A control network for home appliances comprises a module for interfacing an appliance to the network. The module adopts the identity of the appliance when the module and the appliance are being interconnected. The appliance comprises a tag, e.g., in its power plug, with identifying information that gets read by the module and transferred to a controller. The module itself can have a location dependent identifier to enable topology dependent software applications.

摘要： A method and a device in a communication apparatus for maintaining an established connection between said apparatus and a network node. The connection is established by a mobility management unit for providing a mobility management procedure. An acceptance message is issued by the node in response to a request relating to a first mobility management procedure. If any request relating to a second mobility management procedure issued by an upper layer is received by the mobility management unit after the request relating to the first procedure is transmitted and before the acceptance message is received, a maintaining request to maintain the connection is transmitted to the node in response to the acceptance message.

摘要： An automatic service discovery approach allows a network management system to discover service managed objects from the network, eliminating the need for a user or other management application to provide such information. As a result, a network management system can automatically perform network-level or services level discovery of objects and services for which network components have no understanding. Embodiments are applicable, for example, in the context of management of packet voice (VoIP, VoATM) and metro Ethernet (TLS service) domains, as well as other domains.

摘要： A protocol for wireless data exchange may be used in conjunction with two or more portable computer systems. One of the portable computer systems may be a personal digital assistant (PDA) having an internal or an external wireless communication unit. The protocol can be used by a sending application residing on the portable computer system to transparently send a wireless message to a receiving computer system. The packet is then automatically routed to the proper destination application residing on the receiver utilizing a data type identifier. The data type identifier is used by the receiver, in conjunction with an application registry, to determine the proper destination application.

摘要： A method and apparatus for operating a local server computer of a client-server network includes a technique to receive a request from a client computer of the client-server network. A determination is made whether the request requires dynamically generated information from a servlet object of the client-server network. If so, a specified servlet object corresponding to the request may be uploaded from a remote server computer of the client-server network. The specified servlet object is then executed to obtain dynamically generated information corresponding to the request.

摘要： Peer devices register with a resource locator service so that the peer devices can be uniquely identified in a networking environment. An addressing scheme addresses a peer resource in the networking environment based on the unique identifier of a peer device that is a master publisher of the resource. Based on the addressing scheme, the resource locator service can track the location of the master publisher of the resource as well as additional locations of peer devices that have cached the resource and made it available. In various embodiments, the resource locator service can service requests for peer resources by providing a list of locations where the resource is expected to be available or, in the case of non-compatible requester, provide access to the resource itself.
