摘要： A system and method provides a rate limiting technique in which user traffic is not thrown away and which provides improved performance over conventional techniques. A method of rate limiting in a Local Area Network/Wide Area Network interface comprises the steps of receiving data from the Local Area Network, storing the received data in a first buffer, transmitting the received data from the first buffer to the Wide Area Network, transmitting a PAUSE frame to the Local Area Network to cause the Local Area Network to stop transmitting data, if the first buffer fills to an upper threshold, and transmitting a PAUSE frame with PAUSE=0 to the Local Area Network to cause the Local Area Network to start transmitting data, if the first buffer empties to an lower threshold.

摘要： RPR traffic management concepts are extended to individual client flows while adhering to the station level traffic management functions by using a two tiered shaper approach. The first tier manages the client level SLAs and feeds the second tier which provides the aggregate station level traffic management functions. This approach allows sharing of a single RPR station without the compromises and side affects associated with the other techniques. Apparatus for Resilient Packet Ring traffic management comprises a stage queue selection block operable to hold client and control traffic for transmission, a queue level traffic shaper operable to control an add rate of client data add traffic and to provide queue specific send indications to the stage queue selection block, and a ringlet level traffic shaper operable to control traffic flow for a Resilient Packet Ring ringlet and to provide aggregate send indications to the stage queue selection block.

摘要： The capability to handle the 100 μs RPR interrupt and similar interrupts is provided by servicing selected interrupts outside of the operating system. This drastically reduces the latency and overhead associated with servicing the interrupt. A method of handling an interrupt in a computer system comprises receiving the interrupt at the computer system, determining whether the interrupt is a selected interrupt, and performing interrupt processing not involving an operating system of the computer system, if the interrupt is a selected interrupt.

摘要： A method and system for communicating traffic on an emulated subnetwork of a telecommunications ring having a plurality of nodes interconnected by a transmission media includes obtaining traffic at a node on the telecommunications ring. The traffic is segmented into a plurality of discrete segments. A set of broadcast cells is generated by adding an address header to each segment. The address header identifies a virtual channel dedicated to the node on the subnetwork in the telecommunications ring. The set of broadcast cells are transmitted in the virtual channel of the subnetwork and within a frame of the telecommunications ring. At each remaining node on the telecommunications ring, in response to receiving the set of broadcast cells in the virtual channel, both retransmitting and processing the broadcast cells.

摘要： A method may include receiving a stream of datagrams, the datagrams having a first bit length. The method may also include selecting a block of bits from consecutively-received datagrams, the block having a second bit length greater than the first bit length. The method may additionally include determining whether a particular data field is present at a particular bit position within the block. The method may further include outputting the block as a valid block in response to determining that the particular data field is present at the particular bit position. The method may additionally include, in response to determining that the particular data field is not present at the particular bit position: discarding a received datagram from the stream of datagrams; and repeating the receiving, selecting, determining, and discarding steps until a determination is made that the particular data field is present at the particular bit position.
