摘要： In a data communication internetwork including a source station, an end station, and a default router for the source station, a default communication path including the default router is defined between the source station and the destination station. During operation of the data communication internetwork, a shortcut data communication path by passing the default router is established between the source station and the destination station, such that data packets transmitted by the source station are not received by the default router. After the shortcut communication path has been established, a control frame containing source-route information regarding the source station is transmitted to the router, and the source-route information is stored at the router. In this manner, the default router can efficiently direct data packets to the source station and facilitate the establishment of shortcut communication paths terminating at the source station even though the default router is bypassed by a shortcut communication path.

摘要： Packets are encapsulated and sent from a service node to one or more application nodes for applying one or more Layer-4 to Layer-7 services to the packets. Before which for a packet, the service node performs a lookup operation based on a destination address of the packet in a routing data structure derived from a exterior network protocol, such as, but not limited to Border Gateway Protocol (BGP). This lookup operation results in the identification of a next hop packet switching device to which the packet would be sent from the service node. The service node includes this identification of the next hop address in the request packet sent to the application node(s). After the service(s) are applied to the packet, an application node will send the services-applied packet to this next hop address. In this manner, application nodes do not need to run an exterior network protocol. Although, they typically will run an Interior Gateway Protocol for identifying how to forward packets to the next hop address.
摘要翻译：分组被封装并从服务节点发送到一个或多个应用节点，以将一个或多个第4层到第7层服务应用于分组。在分组之前，服务节点基于来自外部网络协议（例如但不限于边界网关协议（BGP））的路由数据结构中的分组的目的地地址来执行查找操作。该查找操作导致从服务节点发送分组的下一跳分组交换设备的标识。服务节点包括发送到应用节点的请求分组中的下一跳地址的标识。应用程序节点将该服务应用于数据包后，将将应用服务的数据包发送到下一跳地址。以这种方式，应用节点不需要运行外部网络协议。虽然，它们通常将运行内部网关协议，用于识别如何将数据包转发到下一跳地址。

摘要： A method is implemented to enable networks employing source-route bridging to participate in route switched, Asynchronous Transfer Mode (ATM), networks. Such source-routed networks, for example, Token-Ring LANs, incorporate an end-to-end route description in the data packets transmitted by the source station. The end-to-end route description is contained in a Route Information Field (RIF). The method implemented herein associates an RIF with the ATM address corresponding to a destination station. This permits the source-route bridged network to exploit the efficiencies of layer-2 connections and the high-speed switching characteristics of the ATM network.

摘要： An ATM communications network with several ELANs allows steady-state data to be passed between ATM attached devices which bypasses intermediate LECs and bridges. Connected to the ATM communications network is a bridge unit which includes a bridge and associated LECs. Also, an origination ATM attached device and a destination ATM attached device are attached to the ATM communications network via a first by a first ELAN and a second ELAN, respectively. The origination ATM attached device sends a request for an ATM address associated with the destination ATM attached device to the bridge, via the first ELAN. After some processing, the bridge returns the ATM address associated with the destination ATM attached device to the origination ATM attached device. This allows the origination ATM attached device to establish a shortcut VCC with the destination ATM attached device using the ATM address associated with the destination ATM attached device, thereby bypassing intermediate bridges and LECs.

摘要： A method and system for providing enhanced peer redundancy in an ATM emulated local area network (ELAN) served by a primary LAN emulation server (LES), a peer LAN emulation server, a broadcast and unknown server (BUS), and a LAN emulation configuration server (LECS). An enhanced peer redundancy virtual channel connection (VCC) is established between the primary LES/BUS and the peer LES/BUS. The primary LES/BUS and the peer LES/BUS exchange status messages every two seconds indicating the number of assigned LECs. If the primary has fewer LECs than the peer, the primary yields to the peer as the active LES/BUS. If an enhanced redundancy VCC was not established, the backup LES/BUS provides ELAN services while waiting for the primary to call to establish an enhanced redundancy VCC. If an enhanced peer redundancy VCC cannot be established, the primary attempts to establish a redundancy VCC with the peer in which the peer LES/BUS is kept in a dormant mode as long as the redundancy VCC is present. If the redundancy VCC is absent, the peer LES/BUS is activated to service the ELAN.

摘要： A method and system are disclosed for balanced transmitting of data across a link aggregation of k links in a network, where k is not a power of 2, where data is specified by frames each having a source address and a destination address. N bits of the source address and N bits of the destination address are determined to be XORed together where N is greater than 2. An index table with 2N entry positions is created where each of the entry positions is assigned an index number between 0 and 2N−1. The entry positions of the index table are filled with one link of the k links in each entry position by repetitively entering each of the k links until all of the entry positions are filled. The frames of data with identical source address and destination addresses as other frames of data are grouped into a flow. N bits of the source address are XORed together with N bits of the destination address for each flow to obtain an N bit index number for each flow. The index table is accessed with the N bit index number to identify a particular link within the index table. The flow is transmitted across the particular link.

摘要： When multi-destination traffic is distributed through a host or switch, the decision to distribute each frame is performed by each egress port and not the ingress port. Within a link aggregation group, the multi-destination frame is sent to each of the egress ports within the link aggregation group. Each of such ports will then determine whether it should re-transmit the frame. If not, the frame is discarded.

摘要： A method for providing interoperability between multiple versions of LUNI within a mixed Asynchronous Transfer Mode emulated LAN is disclosed. The mixed ATM emulated LAN includes multiple LAN emulated clients (LE clients) having different versions of LAN Emulation User Network Interface (LUNI), such as a first version LUNI and a second version LUNI. The mixed ATM emulated LAN is served by a LAN Emulation Server (LES), a Broadcast and Unknown Server (BUS), and a LAN Emulation Configuration Server (LECS). When an LE Control Frame is being sent by an LE client having a second version LUNI, a determination is made as to whether or not the LE Control Frame will be received by an LE client having a first version LUNI. In response to a determination that the LE Control Frame sent by the LE client having a second version LUNI will be received by an LE client having a first version LUNI, the LE Control Frame is copied, and the copied LE Control Frame is converted to an LE Control Frame with a format that is readable by the LE client having a first version LUNI.
