摘要： A loop network hub port with an automatic bypass feature. The automatic bypass feature causes the hub port to enter a bypass mode upon detection of a specified loop failure initialization sequence from a node port attached to the hub port. The hub port does not propagate loop failure initialization data generated by the attached node port upon the failure of a data channel from the hub port to the node port. The hub port replaces loop failure initialization data received from the node port with buffer data and conceals the node port failure from the remainder of the loop. Upon detection of the loop failure initialization sequence received from the attached node port, the hub port enters a bypass mode and maintains that bypass mode until a recovery sequence is received from the node port. At that point, the hub port reinserts the node port into the loop.

摘要： A hub port which maintains a constant phase in a datastream and reduces jitter transfer to an attached node port. The hub port includes circuitry for maintaining constant bit boundaries for all data transmitted along the hub loop from that hub port using an internal clock. In addition, the internal clock is used to reduce jitter transfer.

摘要： A hub port in a hub which preferably eliminates the transfer of jitter in the signal transmitted to an attached node port. In one implementation, jitter transfer is preferably eliminated by transmitting data to an attached node port using a local clock internal to the hub rather than a clock signal recovered from the datastream. The hub port includes smoothing circuits to synchronize data received from the attached node port to the local clock.

摘要： A scalable hub divided into a plurality of internal hubs. Each internal hub is connected to a subsequent internal hub in a loop topology. The connection point for each internal hub to the interhub loop is a port which either bypasses that internal hub, isolating the disconnected internal hub, or connects that internal hub to the interhub loop, such that data flows between that internal hub and the interhub loop. In addition the preferred embodiment provides graceful degradation when an internal hub connected to the interhub loop fails.

摘要： In a loop network system, a method and apparatus for automatic bypass of a node port associated with a hub port when the node port generates a number of errors beyond a threshold level. In one aspect, a programmable error control circuit provides this automatic bypass. The tolerance level is set through programmable parameters including a number of errors as well as a time interval to evaluate the number of errors detected. After a node port has been bypassed by the error control circuit, the error control circuit continues to monitor the error generation of the node port. When that error generation has reached an acceptable tolerance level, the error control circuit automatically reinserts the node port into the loop. The error control circuit provides statistical reporting on the number of errors as well as the number of bypasses generated at a particular hub port.

摘要： A loop network hub including a hub port with a loop initialization insertion mechanism. The loop initialization insertion mechanism causes a hub port which detects a new node port connection to automatically begin generating loop initialization data. A hub port continues to generate loop initialization data until that hub port receives a loop initialization sequence. The loop initialization data propagates around the loop of the hub, halting ordinary processing. In this way, the entire loop is cleared. Upon receiving a loop initialization sequence, the hub port originating the loop initialization data inserts the new node port into the loop. At this point, loop initialization begins and each node port in the loop network obtains a unique loop network address.

摘要： A hub port in a Fibre Channel loop for detecting and bypassing attached node ports in an OLD-PORT state is disclosed. The hub port includes a hub data source, a detect circuits, and an output control circuit. The hub data source supplies data to the hub port from a Fibre Channel loop. The detect circuit is configured to detect a valid non-Arbitrated Loop sequence from an attached node port indicating that the node port is in an OLD-PORT state. The output control circuit operates to bypass the node port from the loop when the valid non-Arbitrated Loop sequence is detected.

摘要： A multi-port hybrid-based cancellation network may include a first and second hybrid coupler, and a first and second two-port network. The second hybrid coupler may be distinct from the first hybrid coupler. The first two-port network may include a first filter connected between the first and the second hybrid couplers. The second two-port network may include a second filter that is distinct from but essentially the same as the first filter connected between the first and the second hybrid couplers. Other circuitry components may be connected to one of the ports of multi-port hybrid-based cancellation network. These other circuitry components may have a configuration that increases or maximizes signal isolation between at least two of the ports of the multi-port hybrid-based cancellation network.
