摘要： Delay times are modified in full-duplex Ethernet network devices by calculating in each network station a delay interval based on a size of a transmitted data packet and a desired transmission rate. The network station waits the calculated delay time before transmitting another data packet, ensuring that the overall output transmission rate of the network station corresponds to the assigned desired transmission rate. The desired transmission rate is received as a media access control (MAC) control frame from a network management entity, such as a switched hub. Hence, each station operates at the desired transmission rate, minimizing the occurrence of congestion and eliminating the necessity of PAUSE frames.

摘要： Delay times are modified in Ethernet network devices by adding an integer multiple of a delay interval to the minimum interpacket gap (IPG) interval, and decrementing the integer in each network station in response to detected activity on the media. Each station has a unique integer value from the range of zero to the number of stations (N) minus one. The unique integer value ensures that each station has a different delay interval in accessing the media after sensing deassertion of the receive carrier. The station having a zero integer value will have its integer counter reset to (N-1) after a station transmits a data packet on the network, and the stations having nonzero integer values decrement their respective integer counters. Each network station also includes a deferral timer that counts the maximum delay interval of (N-1) delay intervals plus the minimum IPG value, and thus establishes a bounded access latency for a half-duplex shared network.

摘要： Delay times are modified in Ethernet network devices by adding an integer multiple of a delay interval to the minimum interpacket gap (IPG) interval, and decrementing a deferral counter storing the integer in each network station in response to detected activity on the media. Each station independently determines the number of stations active on the network media by counting the number of successful packet receptions following a corresponding detected collision. Once the number of detected collisions equals the number of stations (N) minus one, each station independently establishes a unique integer value from the range of zero to the number of detected collisions, i.e., up to the number of stations (N) minus one, by resetting the deferral counter to (N-1) after a successful transmission, and by decrementing the deferral counter upon detection of a successful transmission without collision by another station. The unique integer value ensures that each station has a different delay interval in accessing the media after sensing deassertion of the receive carrier. Each network station also includes a deferral timer that counts the maximum delay interval of (N-1) delay intervals plus the minimum IPG value, and thus establishes a bounded access latency for a half-duplex shared network.

摘要： A network includes a combination of carrier-sense stations and Universal Multiple Access (UMA) stations using a time slot multiple access protocol. The network is configured to include assigned time slots for the respective UMA stations and unassigned time slots reserved for the carrier-sense stations to access the shared network media. Each of the UMA stations is provided with a corresponding assigned time slot and the total number of time slots. Since the UMA stations access the media only during the assigned time slot, the carrier-sense stations can contend for access to the media after waiting a minimum interpacket gap (IPG) after sensing deassertion of the receive carrier on the media. The UMA stations may also be modified to attempt access of the media using Ethernet-compliant, carrier-sense multiple-access with collision detection (CSMA/CD) protocol when a current time slot corresponds to a mixed-use time slot.

摘要： Collision delay intervals are modified in Ethernet network devices transmitting priority data requiring a guaranteed latency by multiplying an integer multiple number of slot times with a fractional coefficient. A network device having priority data for transmission uses the conventional Truncated Binary Exponential Backoff (TBEB) algorithm during the first access attempt to calculate a collision delay interval from a randomly selected integer multiple of slot times. If the network device encounters another collision, the next randomly selected integer multiple of slot times is multiplied by the fractional coefficient. Use of the fractional coefficient during collision mediation on a half-duplex Ethernet network provides a bounded access latency for real-time and multimedia applications by granting the network device a higher probability of successfully accessing the network media.

摘要： A network switch having switch ports for full-duplex communication of data packets with respective network nodes according to IEEE 802.3 protocol dynamically allocates bandwidth between the switch ports based upon detected activity from the network nodes. The network switch generates an assigned bandwidth value for each active switch port based upon the switch capacity and the number of active switch ports. Each active switch port forwards the assigned bandwidth value to the corresponding network node as an IEEE 802.3x[2] compliant media access control (MAC) control frame, enabling the corresponding network node to calculate its programmed interpacket gap interval following a packet transmission based upon the size of the transmitted packet and the assigned bandwidth. Each active switch port also calculates the programmed interpacket gap to determine if reception of another data packet has begun by the end of the programmed interpacket gap interval. If no data packet is received by the corresponding port after the programmed interpacket gap interval, the network switch considers that switch port as non-active, recalculates, and reassigns the unused bandwidth to the remaining active ports. The dynamic bandwidth allocation by the network switch enables the input buffer size to be optimized without requiring an excessive switch bandwidth.

摘要： Apparatus and method for more precise controlling of congestion on a network, provides for remote controlling of a remote station on the network by a local station to configure the remote station into a remote loopback configuration. With the remote station thus configured, the local station is then able to determine the link latency of the link, during auto-negotiation, for example. Provided with the link latency, a congestion control algorithm in the local station may be adjusted to account for the link latency to better control the input data streams by controlling when the congestion relieving control signal, such as a PAUSE frame, is transmitted to the remote station to inhibit transmission and relieve congestion.
