摘要： A method for sending a frame of data from a first channel to a second channel comprises reserving q of n available buffers of m total buffers to the first channel. A frame that is received from the first channel in i of the q buffers is stored and the status is changed to unavailable. The frame is selectively assigned to the second channel based on a number of the buffers j assigned to the second channel and a number of the buffers h neither reserved nor assigned to any channel, wherein i+j≦m and h+q≦n. The i buffers storing the frame are assigned to the second channel if the frame is assigned to the second channel. The status of the i buffers is changed to available if the frame is subsequently sent over the second channel.

摘要： A network device for transferring data from a first network to a second network comprises a switch comprising a first port adapted to receive a frame of the data from the first network and a second port adapted to transmit the frame to the second network. The frame comprises a plurality of words including a first word comprising a first portion of an internet protocol address and a second word comprising a second portion of the internet protocol address. The switch adds one or more bits to the frame so that the first and second portions of the internet protocol address appear within a single word of the frame. A processor receives the frame from the switch, and to modify the internet protocol address in the frame. The switch receives the frame from the processor, and removes the one or more bits from the frame before the second port transmits the frame to the second network.

摘要： Embodiments of the present invention provide techniques for both ends of a link suffering from duplex mismatch to correct the duplex mismatch. According to some embodiments, the half-duplex end of the link can detect that the other end of the link is in full-duplex mode by detecting late and/or very late collisions, and can correct the duplex mismatch by changing to full-duplex mode. According to some embodiments, the full-duplex end of the link can detect that the other end of the link is in half-duplex mode by one or more techniques including detecting cyclic redundancy check (CRC) errors and frame fragments, and can correct the duplex mismatch by changing to half-duplex mode.

摘要： An integrated circuit (IC) within an IC package, where the IC includes a memory control module and a timing module. The memory control module is configured to control read/write operations of a memory IC via N pins of the IC package, where N is an integer greater than 1. The memory IC is external to the IC package. The timing module is configured to control on/off timing of (N*M) light emitting diodes (LEDs) arranged in N columns and M rows connected to the N pins and M pins of the IC, respectively, where M is an integer greater than 1. The read/write operations utilize the N pins during a first period. The N*M LEDs receive data from the M pins and refresh signals from the N pins during a second period that is different than the first period.

摘要： Apparatuses, methods, systems, and circuits for controlling a network connection status indicator (such as a light-emitting diode) are disclosed. In one embodiment, a method of controlling a status indicator includes receiving a data unit of fixed or predetermined length in a device coupled to the network, detecting whether the received data unit is a protocol control unit (e.g., a timing protocol frame), restricting activity of the status indicator in response to the received data unit being detected as the protocol control unit, and allowing the activity of the status indicator in response to the received data unit being detected as a unit type other than the protocol control unit.
