    摘要： Apparatus and method for storing network frame data which is to be modified. A plurality of buffers stores the network data which is arranged in a data structure identified by a frame control block and buffer control block. A plurality of buffer control blocks associated with each buffer storing the frame data establishes a sequence of the buffers. Each buffer control block has data for identifying a subsequent buffer within the sequence. The first buffer is identified by a field of a frame control block as well as the beginning and ending address of the frame data. The frame data can be modified without rewriting the data to memory by altering the buffer control block and/or frame control block contents without having to copy or rewrite the data in order to modify it.

    摘要： According to the present invention there is provided to a method and system for efficiently routing IP fragments (i.e., datagrams) at layer 3 through layer 7 of the OSI model without reassembling the fragments. Time-consuming reassembly of fragments of a datagram at higher layers that would be required via conventional methods is avoided, thereby improving processing speed of fragments and utilizing fewer resources for processing fragments of a datagram than would be required during reassembly of the fragments via conventional methods. The method and system route a datagram that has been fragmented into a plurality of fragments utilizing content-based routing information included in one or more fragments of the plurality of fragments, comprising: generating a context for the datagram associated with routing the plurality of fragments of the datagram and setting the context for the datagram to passive until content-based routing information included in the one or more fragments is received; caching received fragments while the context is set to passive; determining a destination for routing the plurality of fragments when content-based routing information included in the one or more fragments is received and setting the context for the datagram to active; and routing any cached fragments and subsequently received fragments of the datagram to the determined destination while the context is active without reassembling the plurality of fragments into the datagram. Additionally, a router and server load balancer incorporating the present invention are provided.

    摘要： A technique for permitting continued use of IP (Internet Protocol) routing protocols in an Asynchronous Transfer Mode (ATM) network is implemented in each ATM system having route-computing responsibilities. When a call setup request is received, the routing system determines, from the ATM address of the target system, whether a routing protocol must be implemented. If a routing protocol must be implemented, data in an ACN (ATM Cluster Number) field and an HN (Host Number) field in the target ATM address is read and is imported into an IP-format address. This IP-format address is used in implementing the IP routing protocol.

    摘要： The invention includes a bridge having n ports (n>1), each port being connected to a Token-Ring physical segment, each physical segment having one native Token-Ring workstation attached. The bridge to the workstations a single Token-Ring logical segment with a single Active Monitor and a single Ring Number. The invention includes a centralized medium access control (MAC) function inside a centralized processor instead of a MAC function implemented at each port of the bridge; the frame handling function, due to the fixed and limited configuration (same bridge Active Monitor seen by all connected stations), does not require a multi-port bridge function, but a simpler switch function between ports. Bridge clocking is also simplified, and a cost effective unshield twisted pair (UTP) retiming solution is presented.

    摘要： A distributed switch may include a hierarchy with one or more levels of surrogate sub-switches (and surrogate bridge elements) that enable the distributed switch to scale bandwidth based on the size of the membership of a multicast group. Moreover, each surrogate may optimize the hierarchy according to one or more optimization criteria. For example, each surrogate in the hierarchy may have the necessary information to ensure that if the next surrogate in the hierarchy is unavailable, the data may be routed to a backup surrogate. The selected hierarchy may be further optimized by skipping surrogates (or a surrogate level) such that the data intended for a skipped surrogate is sent to a surrogate in a lower-level of the hierarchy. This may better utilize the connection interfaces in the transmitting sub-switches and eliminate any unnecessary surrogate-to-surrogate transfers.
