Abstract
A method of handling data in a memory of a network device is disclosed. The method includes the steps of storing portions of a datagram, being handled by a network device, in a memory, where the memory comprises two logic memory blocks, storing at least two pointers with the portions of the datagram in the memory, where one of the at least two pointers points to a next portion of the memory to be accessed, retrieving the portions of the datagram and the at least two pointers when the network device is ready to act on the datagram, polling a register to determine which of the at least two pointers actually points to the next portion, retrieving the next portion, when necessary and acting on the datagram based on the processing of the datagram by the network device.
