摘要: A method for buffer management and a controller of the same are disclosed. In the buffer management method, a first control mode is performed, and a plurality of bits are used to control a bit mask region of a memory. A second control mode is performed, and a plurality of unused addresses in a link region of the memory is cached. A third control mode is performed, to control a plurality of second unused addresses in the link region by a linked list. The controller comprises a plurality of bits for controlling a bit mask region; a plurality of address cache units for caching a plurality of first unused address of a linked list in a link region; and a pointer for always pointing to a head of the linked list in the link region, wherein the linked list links a plurality of second unused addresses.

摘要: An Ethernet switch with rate control and associated method is provided. Each port in the switch has individual settings of egress/ingress) rate control, which are stored in a register and configured based on required rates. The switch uses data volume that a port can output/input within each unit time to control egress/ingress rate of the port. Further, the egress rate can be precisely controlled by using uniform random numbers provided by an random number generator of the switch, and the ingress rate can be advantageously controlled by combining a proper kind of congestion control, which is performed according to the capability of a device connected to the port, such as full-duplex or half-duplex, and flow control.

摘要: A method of early release of buffers and a related media access control chip are disclosed, wherein the method includes the steps of: receiving an Ethernet packet from a port, allocating a buffer area having a plurality of buffers stitched sequentially for storing the Ethernet packet, transmitting the Ethernet packet from the destination port, and releasing the buffers when the transmission starts if the destination port is full-duplex transmission mode, or releasing the buffers after at least 128 bytes of the packet is transmitted if the destination port is half-duplex transmission mode. The Ethernet packet can be either uni-cast, multi-cast or broadcast.
