    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： In a multicast capable IP network implemented over an ATM network, each client terminal on a multimedia conference, for each media type it transmits, is assigned a multicast IP address and a port number (together known as a socket) on which to transmit packets, wherein each assigned multicast IP address is unique and different than the multicast IP address assigned to any other client for any media type. Each client terminal then selects, for each media type, which clients on the conference it wants to receive packets from. Only packets that are in fact requested by a client are routed over the multicast IP network to the requesting client. A single special purpose Multicast Address Resolution System (MARS) server is associated with the conference when the conference is established. Each client terminal uses that MARS server, whether on the same or different IP sub-networks, but on a common ATM network, for purposes of mapping the multicast IP addresses used in the conference into a set of unicast ATM endpoint addresses used by the ATM-connected client terminals. Similarly, when a specific conference uses a Multicast Server, a single special purpose Multicast Server is used for all clients on the conference, whether on the same or different IP sub-networks, for purposes of establishing point-to-multipoint ATM connections to the conference endpoints.

    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： In a multicast capable IP network, each client terminal on a multimedia conference, for each media type it transmits, is assigned a multicast IP address and a port number (together known as a socket) on which to transmit packets, wherein each assigned multicast IP address is unique and different than the multicast IP address assigned to any other client for any media type. Each client terminal then selects, for each media type, which clients on the conference it wants to receive packets from. Only packets that are in fact requested by a client are routed over the multicast IP network to the requesting client. When a conference originator establishes the conference, a number of multicast IP addresses are allocated for later assignment to the clients during the conference. As each client joins the conference, it is assigned a multicast IP address from the allocated group for each media type it will transmit. Those assigned addresses are then marked as unavailable for assignment to any other client that subsequently joins the conference. When the original client later exits the conference, its assigned multicast IP address(es) is (are) marked as available for assignment to a later joining client. At the conclusion of the conference, all multicast IP addresses allocated to the conference are marked as available for use in another conference.

    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。
