摘要： A name mapper, name servers, and multimedia servers are connected to a multimedia manager. Each client has the name of a multimedia server, i.e., a virtual host name, from which it can obtain multimedia service. The name server stores associations of server host names to layer-3 addresses. When a client initiates a multimedia session, it requests the layer-3 address of the server that corresponds to its server's name. The name server sends the layer-3 address of the one of the multimedia servers that is currently designated as corresponding to that name. The multimedia client stores the name-to-layer-3 address binding in it's cache. The multimedia client then establishes communications with the multimedia server at that layer-3 address and clears its cache. The dynamic name-to-layer-3 address binding in the name server is managed by the name mapper, which may be collocated with the multimedia manager or may be located on a separate server. The multimedia server manager collects real-time status information so that it knows the availability of the multimedia servers in the network. If a multimedia server, whose layer-3 address is presently mapped to from a virtual host name, becomes unable to serve additional clients, the multimedia server manager sends a message to the name mapper to modify the name to layer-3 address binding. The modification specifies an available server's layer-3 address to be bound in place of that of the server that became unable to serve additional clients.
摘要翻译：名称映射器，名称服务器和多媒体服务器连接到多媒体管理器。每个客户端具有多媒体服务器的名称，即虚拟主机名称，从中可以获得多媒体服务。名称服务器将服务器主机名的关联存储到第3层地址。当客户端启动多媒体会话时，它会请求与其服务器名称对应的服务器的第3层地址。名称服务器发送当前指定为与该名称对应的多媒体服务器之一的第3层地址。多媒体客户端将名称到第3层地址绑定到其缓存中。然后多媒体客户端在第3层地址建立与多媒体服务器的通信，并清除其高速缓存。名称服务器中的动态名称到层3地址绑定由名称映射器管理，名称映射器可以与多媒体管理器并置，或者可以位于单独的服务器上。多媒体服务器管理器收集实时状态信息，以便它知道网络中多媒体服务器的可用性。如果多层服务器的第3层地址目前从虚拟主机名映射，则无法为其他客户端提供服务，多媒体服务器管理器会向名称映射器发送消息，将名称修改为第3层地址绑定。修改指定要绑定的可用服务器的第3层地址，而不是无法为其他客户端提供服务的服务器地址。

摘要： A pool of multimedia servers, which may be geographically diverse, are available to be allocated to serve one of at least two ELANs served by an ELAN contronect network. These multimedia servers are a) connected to, b) dynamically allocated to sub-ELANs, and c) managed by, a multimedia server manager, which is included as part of the ELAN contronect network. In particular, each of the multimedia servers is capable of having its addresses dynamically reconfigured in response to commands from the multimedia server manager to match that of an ELAN to which it is being made available, so that the multimedia server becomes a part of that ELAN. The multimedia server manager obtains a layer-3 address from address server 427 of the ELAN contronect network which it then assigns to the multimedia server so that the multimedia server appears to be a part of the ELAN to which it is assigned to serve. The multimedia server manager also supplies to the multimedia server the LES and BUS address of a sub-ELAN of the ELAN to which it is assigned to serve. The multimedia server can then join with the LES and BUS as a LEC in that sub-ELAN.

摘要： A method is provided for establishing a communication session over a path supported at least in part by a telephony network and an ATM network. The telephony network includes ingress and egress telephony switches and the ATM network includes ingress and egress ATM switches. A first call setup request is received at the ingress telephony switch from an originating node and the ingress telephony switch selects a first available trunk from the ingress telephony switch to the ingress ATM switch. A communications path is established over the available trunk to the ingress telephony switch. A second call setup request is transmitted from the ingress telephony switch to the egress telephony switch and the egress telephony switch selects a second available trunk from the egress telephony switch to the egress ATM switch. A third party set up command is transmitted from one of the telephony switches to one of the ATM switches requesting establishment of a virtual connection between the ingress and egress ATM switches over the ATM network. A virtual connection is established between the ingress and egress ATM switches. The egress telephony switch connects the second available trunk to a third trunk in communication with a destination node such that the destination node is informed of a request to establish a communication session with the originating node.

摘要： A telecommunications network is provided for establishing communication between at least one originating station and at least one destination station. The network includes a plurality of IP switches for addressing and routing data in accordance with an Internet protocol and an ATM protocol. A server, which is coupled to at least one of the IP switches, receives at least one service attribute requested by the originating station in communication with the IP switch. A network control point (NCP) is employed to provide data, in response to a request from the server, pertaining to the service attribute. At least one address database is associated with each of the IP switches. The address database includes a subset of the data available in the NCP.

摘要： A new type of data transport service which uses a frame relay layer 2 data link connection identifier (DLCI) to select among various service types, feature sets, and/or closed user groups (CUGs). A layer 3 address may be extracted from a layer 2 frame, and the layer 3 address information may be used to route a data packet over a packet-switched network according to the service classes, feature sets, and/or CUGs selected. At the destination, the layer 3 data packet may again be enclosed in a layer 2 frame with a DLCI indicating the service classes, features sets, and/or CUGs. Because the use of conventional permanent virtual circuits (PVCs) is not required in aspects of the invention, new methods of measuring and managing network traffic are presented.
