摘要： Aspects disclosed herein address the need in the art for memory management for high speed media access control. A packet buffer may store packets with a first data structure, comprising the packet length, sequence number, and a pointer to a second data structure. Packet data may be stored in a linked list of one or more second data structures. Transmit and receive queues may be formed using linked lists or arrays of the first data structures. Memory locations for storing first and second data structures may be kept in lists indicating free locations for the respective data structure types. A flexible memory architecture is disclosed in which two configurations may be selected. In a first configuration, a first memory comprises per-flow parameters for multiple flows, and a second memory comprises a packet buffer.; In a second configuration, the first memory comprises per-flow pointers to per-flow parameters in the second memory. The packet buffer resides in a third memory. Various other aspects are also presented.

摘要： The present invention discloses a method for encapsulating data stream. In this method, preset a buffer area, and set a low value in it. When there is a require to encapsulate the data stream, judge whether the length of the data in the buffer reach the low value. If reach, divide the data in the buffer according to the preset length which less than or equal to the low value, and add the header to the divided data. Otherwise, don’t divide the data in the buffer. Using the present invention, the data steam can be encapsulated with dividing the received data stream and adding the header and end to it. Because it need’t distinguish data character or control character, so the executive process can be completed more simply and more efficiently.

摘要： A process of handling packet data in a packet buffer is disclosed. Free pointers are stored in a plurality of free pointer queues, with each of the plurality free pointer queues in a form of a linked list and the free pointers are retrieved from each of the plurality of free pointer queues and storing in a prefetch memory to provide a throughput of one free pointer per clock cycle. When an initial portion of a data packet is received, two free pointers are retrieved from the prefetch memory. One of the two free pointers is stored in a start pointer register connoting a start of the data packet and one free pointer is supplied for data elements of the data packet. One free pointer per middle data element is supplied, while no new pointer is needed for the end of packet data element. The start of the data packet is linked with an end of packet portion of a previously received packet in an output queue memory and a data element is read out of the data packet from the output queue memory when selected by a transmission scheduler and releasing a pointer of the data element to one of the plurality of free pointer queues in a way that balances the lengths of all free pointer queues. Additionally, all pointers of a packet are released to one of the plurality of free pointer queues within one cycle when the packet is dropped.

摘要： A dispatch mechanism is provided for dispatching data units, (e.g. datagrams or packets) divided into one or more fragments, via a telecommunications network. The dispatch mechanism includes a queue for queuing fragments for transmission. It further includes a queue controller operable when a fill level of the queue exceeds a threshold value to discard fragments of data units for which a fragment has not already been queued and to add to the queue fragments of data units for which a fragment has already been queued. The dispatch mechanism maintains a record of data units which are to be transmitted (that is when one fragment of the data unit has already been passed for despatch) and a record of data units which are to be dropped (that is data units for which a fragment has already been dropped). The dispatch mechanism enables more effective use of network capacity by reducing the possibility of incomplete data units being transmitted over the network. In other words, where one data unit fragment is dropped, a mechanism ensures that all remaining fragments of that data unit are dropped. Also, where one data unit fragment has been sent, the mechanism ensures that all other fragments for that data unit are sent, irrespective of the fill level of the output queue when a data fragment for transmission is processed.

摘要： A method and arrangement for reclaiming buffers used to store frames, following the transmission of a frame, checks to determine whether the transmission of a frame is the last copy of that frame to be transmitted. If it is the last copy, or the only copy, the buffers storing that frame are reclaimed for reuse after the contents of each buffer are transmitted. If the frame is not the last copy, or it cannot be determined whether it is the last copy, then the frame is transmitted and a count of the number of transmitted copies of that frame is decremented. Once all of the copies have been transmitted, the buffer reclaiming process is initiated.
