摘要： The rate-based scheduling for a network application is used to control the bandwidth available to a flow while scheduling the transmission of the flow. The rate-based scheduling uses rate credits to represent the amount of data a flow is permitted to transmit and only permits a flow to transmit if the flow has rate credit available. A flow is permitted to transmit only if the peak packet rate for the scheduler has not been exceeded.

摘要： Memory access efficiency for packet applications may be improved by transferring full partitions of data. The number of full partitions written to external memory may be increased by temporarily storing packets using on-chip memory that is on a chip with the processor. Before writing packets to external memory, packets of length smaller than the external memory partition size may be temporarily stored in the on-chip memory until an amount corresponding to a full or nearly full partition has been collected, at which point the data can be efficiently written to an external memory partition.

摘要： A memory is divided into a number of partitions. The partitions are grouped into a first group of partitions and a second group of partitions. When required by a port, a partition is assigned to the port from a pool of un-assigned partitions. The pool of un-assigned partitions comprises of un-assigned partitions from the first group of partitions and un-assigned partitions from the second group of partitions. The un-assigned partitions from the first group of partitions are assigned to the port until a first threshold is reached. The un-assigned partitions from the second group of partitions are assigned to the port after the first threshold is reached. A second threshold is used to limit a total number of partitions assigned to the port.

摘要： A method and apparatus for providing a virtual output queue (VoQ) from a received set of data packets in a multi-service system. Each packet is divided into at least one partition, including a last partition that includes packet information, such as error status and packet length. The system receives the packet from a flow, parses the packet into partitions, including a first partition and the last partition, places each last partition into a linked list based on a time when the last partition was received, links the last partition to the first partition, and employs the linked list as the output queue. This system allows for rapid compilation and transmission of different sized packets, and obviates the need for the receiving processor to wait for the last partition to discard a bad packet.

摘要： A rate policing algorithm for packet flows is based on counters and threshold checking. The rate policing algorithm utilizes a state machine having four links: (1) compliant state to compliant state; (2) transition from compliant state to non-compliant state; (3) non-compliant state to non-compliant state; and (4) transition from non-compliant state to compliant state. Depending on the values obtained from the counters and utilizing the threshold values, it is determined whether a flow rate for packets is compliant or non-compliant.

摘要： In a communication system that uses virtually concatenated payloads, techniques to determine when to declare and when to clear alarm indication signal (AIS) for a group. The declaration of AIS for a group may occur based on when declaration of AIS for a member of a group occurs. The clearing of group AIS may occur based on when clearing of AIS by a last member of a group to clear AIS occurs.

摘要： A method and apparatus for transferring data traffic, such as in a SONET/SDH environment, is provided. Two designs are presented, each utilizing a dual device design, where one device performs GFP Framing and the other device performs GFP-T adaptation. The method and apparatus include a first device having a first device FIFO, the first device configured to receive data and assemble data into packets and transfer data across a packet interface when the first device FIFO contains more than N bytes. A second device comprises a second device FIFO, the second device configured to receive data packets from the packet interface and utilize a plurality of thresholds to maintain a quantity of data in the second device FIFO within a predetermined range. Depending on the design employed, control codes, such as 65B_PAD control codes, may be added in the first device under certain conditions to facilitate data transfer.
