摘要： Enhanced performance of a WAN is achieved by allowing devices to move from LAN to LAN and have the move be transparent to end user applications. This is accomplished by allowing devices to move, with no action being taken in response to a move. Instead, notice is taken of the LANE Emulation Client (LEC) address at which a device can be reached when the device that moved chooses to communicate with some other device. In such a device initiates communication, a table is updated in a LAN Emulation Server (LES), which is an entity maintained by the WAN that interconnects a number of LECs. A similar table is maintained in each LEC, and the table of each LEC is updated whenever a connection is made between one of its devices and some other device. At times, of course, a LEC would have an incorrect address of a sought destination device. In such a case, the LEC sends a query to the LES, and the LES provides what the LES believes to be the correct LEC address. When the LES cannot resolve an address, a message is broadcast to the LES entities of other “emulated LANs,” or ELANs, which contains their own LES entities, and those LES entities have an opportunity to provide the correct address.
摘要翻译：通过允许设备从LAN移动到LAN并使终端用户应用程序的移动变得透明，可以实现WAN的增强性能。这是通过允许设备移动来实现的，而不采取动作来响应移动。取而代之的是，当移动设备选择与其他设备通信时，会注意到LANE仿真客户端（LEC）地址可以到达设备。在这种设备中启动通信时，在LAN仿真服务器（LES）中更新一个表，该仿真服务器是连接多个LEC的由WAN维护的实体。在每个LEC中保持类似的表，并且每当在其设备和其他设备之间进行连接时，更新每个LEC的表。有时候，LEC会有一个不正确的寻址目标设备的地址。在这种情况下，LEC向LES发送查询，LES提供LES认为是正确的LEC地址。当LES无法解析地址时，会向其他“仿真LAN”的LES实体或包含其自己的LES实体的ELAN广播消息，并且这些LES实体有机会提供正确的地址。

摘要： Cross-service connectivity between use of the telephone network and use of an e-mail data network is provided by enabling a recipient of an e-mail message to receive e-mail messages through an alias e-mail address which is directly associated with the recipient's telephone number. Thus, the alias e-mail address consists of the recipient's telephone number as the recipient name at a well-known and publicized common domain name server. A sender therefore addresses an e-mail message to the recipient to that alias e-mail address using the recipient's alias telephone number name. A message addressed to the alias e-mail address is sent to a translation server at that known domain name, where the alias telephone number-recipient name is translated to the actual e-mail address comprising the recipient's actual name and associated domain name server, and the message is then forwarded to that recipient at that actual e-mail address. Such aliasing capabilities are effected through a registration process in which the recipient registers for such a service and provides to the translation server his or her actual e-mail address and associated telephone number to which senders of messages to that recipient can use to address e-mail messages.

摘要： Real time delivery of multimedia information accessed either through the Internet, or otherwise, simultaneously, or sequentially time delayed to one more users, is enabled by delivering the multimedia information over a switched network via a multipoint control unit. A client establishes a connection with a server, or other remote location where desired multimedia information is resident, identifies the desired multimedia information and provides client information identifying the locations of the users. The client information may include the telephone numbers or other access numbers of each of the multiple users. The multimedia information is then delivered by a multimedia server to a bridging apparatus through a switched network guaranteeing high quality of service, secure connection and billing control. Connecting one or more users to a live agent is also made possible by providing the telephone numbers of the users and the live agent directly to the multipoint control unit. The delivery of the multimedia information can be secured by comparing the client information to a segmented "to call" list to determine whether the client is authorized to receive the requested multimedia information. Alternatively, or in addition, security can be implemented by mounting a video camera at the client's endpoint and connecting a database running face recognition software to the multimedia server. The multimedia server's call to the user triggers the camera to take a picture of the user. The selected content is restricted to authorized users by comparing the picture to pictures of authorized faces stored in the database.

摘要： A multimedia telecommunications network provides telephone service which may involve one or more of audio, video, and data communications. In one example of the invention, the multimedia telecommunications network contains a virtual meeting services complex which provides multimedia telecommunications service to subscribers of the network. Multimedia telephone calls can be completed automatically by the virtual meeting services complex in a manner similar to that now used to complete conventional audio telephone calls. The multimedia telecommunications network containing this virtual meeting services complex is able to connect together users having diverse equipment and is able to handle integrated and nonintegrated network access mechanisms.

摘要： A mobility support technique provides home agents and foreign agents in mobility aware access networks. Participating mobile hosts are assigned a home address that is used by other hosts as the mobile host's address. The home address actually addresses the home agent provided in the mobility aware access network. The home address provides additional privacy to the mobile host because it does not identify the mobile host's home premises network where the mobile host resides permanently absent any mobility of the mobile host. By providing home agents and foreign agents in a mobility aware access network, the agents may cooperatively establish optimal routing paths for data transmitted to a mobile host. The agents may identify a pseudo home agent, an agent in a mobility aware access network located near to a transmitting mobile host, that acts as the home agent of a destination mobile host. The pseudo home agent tunnels data directly to the destination mobile host without requiring the data to be routed first to the true home agent. In this regard, the pseudo home agent establishes a more direct routing path between the transmitting and destination mobile hosts.

摘要： Real-time multimedia services are transmitted over a hybrid network including a nonguaranteed quality of service packet switched local area network and a circuit switched ISDN wide area network having a centralized multimedia bridge located within the wide area network. The local area networks and multimedia bridge are interconnected via ISDN routers. An algorithm executed by the multimedia bridge receives signals from the packet switched network and detects the absence of properties needed for real-time audio visual services. The data signals are processed to compensate for the absence of the properties and then are transmitted over the wide area network to enable real-time audio visual services.

摘要： We have realized that for a connection over a large data network, such as an Internet connection that couples a web access device to a terminal server connected to an applications server, delays associated with the process of downloading large data files over such a connection, occur primarily in the leg of the connection that couples the applications server to a terminal server while little congestion is typically observed in the leg of the connection that couples the Internet access device to the terminal server. The aforementioned delay is reduced by establishing a separate connection from the applications server to the Point Of Presence server outside or independently of the backbone of the large data network thereby allowing users to receive enhanced grade of service for file transfer operations.
摘要翻译：我们已经意识到，对于通过将网络访问设备耦合到连接到应用服务器的终端服务器的大型数据网络的连接，发生与通过这样的连接下载大数据文件的过程相关的延迟主要是在将应用服务器耦合到终端服务器的连接中，通常在将因特网接入设备耦合到终端服务器的连接中通常观察到拥塞很少。通过在大数据网络的骨干网之外建立与应用服务器到存在点服务点的单独连接，可以减少上述延迟，从而允许用户接收文件传输操作的增强等级的服务。
