Abstract: A method and apparatus are provided for discarding a priority fair share of traffic of network connections. In one example, the method receives traffic of at least a particular network connection. A portion of a fixed buffer allocation space is filled with traffic of the particular network connection, wherein a buffer in the fixed buffer allocation space is associated with a fixed buffer allocation queue identification. A portion of a prioritized fair share buffer space is filled with traffic of the particular network connection, wherein a buffer in the prioritized fair share buffer space is associated with a priority fair share queue identification. A portion of the lowest priority traffic of the network connections is discarded.

Abstract: A method and apparatus are provided for caching free cell pointers pointing to memory buffers configured to store data traffic of network connections. In one example, the method stores free cell pointers into a pointer random access memory (RAM). At least one free cell pointer is temporarily stored into internal cache configured to assist in lowering a frequency of reads from and writes to the pointer RAM. A request is received from an external integrated circuit for free cell pointers. Free cell pointers are sent to queues of the external integrated circuit, wherein each free cell pointer in a queue is configured to become a write cell pointer. At least one write cell pointer and a corresponding cell descriptor is received from the external integrated circuit. Free cell pointer counter values are then calculated in order to keep track of the free cell pointers.

Abstract: An apparatus and method are provided for transmitting data using synchronous dynamic random access memory (SDRAM). In example, the method includes writes data using a first set of SDRAM banks. Data is written using a second set of SDRAM banks, wherein the first set of SDRAM banks and the second set of SDRAM banks write interleaved. Data is read using a third set of SDRAM banks. Data is read using a fourth set of SDRAM banks, wherein the fourth set of SDRAM banks and the third set of SDRAM banks read interleaved.
