摘要： A method and apparatus for managing memory for time division multiplexed high speed data traffic is provided. The method and apparatus utilize an interleaving approach in association with multiple memory banks, such as within SDRAM, to perform highly efficient data reading and writing. The design issues a first command or access command, such as a read command or write command to one memory bank, followed by an active command to a second memory bank, enabling efficient reading and writing in a multiple data flow environment, such as a SONET/SDH virtual concatenation environment using differential delay compensation.

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： 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 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.
