摘要： A so-called "ELAN contronect network" is employed to interconnect sub-ELANs to form an ELAN. More specifically, the "ELAN contronect network" is a separate network for interconnecting the servers of the sub-ELANs, where a sub-ELAN is a part of an ELAN having its own LES and BUS that may also be configured as a stand-alone ELAN. Each of the sub-ELANs is connected to the ELAN contronect network via a point-to-point connection-oriented connection, e.g., an asynchronous transfer mode (ATM) connection and the ELAN contronect network is configured to present itself to each of the servers of the sub-ELANs as clients thereof. In a particular embodiment of the invention, the ELAN contronect network includes an address server, a broadcast/route server, a configuration server, multimedia servers, and at least one LAN hub interconnected over a high-speed backbone. The address server contains an address data base for performing address resolution between the at least two addresses of each ELAN end-point in response to requests for such translations. The broadcast/route server receives data packets for broadcast to a different sub-ELAN from which the packets originated and broadcasts the received data packets to at least one other sub-ELAN. The broadcast/route server also recognizes that a packet which is a broadcast packet at layer 2 is actually a request for an address resolution at layer 3. If so, the broadcast/route server collaborates with the address server to perform the necessary address resolution and insures that a response is sent only to the client originating the request.

摘要翻译： 使用所谓的“ELAN contronect网络”来互连子ELAN以形成ELAN。 更具体地说，“ELAN contronect网络”是用于互连子ELAN的服务器的单独网络，其中sub-ELAN是具有其自己的LES和BUS的ELAN的一部分，其也可以被配置为独立的 ELAN。 每个子ELAN通过点对点连接取向连接（例如，异步传输模式（ATM））连接连接到ELAN互斥网络，并且ELAN对抗网络被配置为向自己呈现每个服务器 的子ELAN作为其客户。 在本发明的特定实施例中，ELAN对抗网络包括地址服务器，广播/路由服务器，配置服务器，多媒体服务器以及通过高速骨干网互连的至少一个LAN集线器。 地址服务器包含地址数据库，用于响应于对这种翻译的请求，在每个ELAN终点的至少两个地址之间执行地址解析。 广播/路由服务器接收用于广播的数据分组到发起分组的不同子ELAN，并将接收到的数据分组广播到至少一个其他子-ELAN。 广播/路由服务器还认识到，在层2处作为广播分组的分组实际上是在层3处的地址解析请求。如果是，则广播/路由服务器与地址服务器协作以执行必要的地址解析和 确保响应仅发送给发起请求的客户端。
