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： 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： 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： 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.
