A method for word synchronization can be applied to asynchronous devices including SERDES devices connected across serial lines. A state transition methodology characterizes the state of the device based on control characters received consistently across the serial lines and channels the system to a state of word synchronization. Loss of synchronization and transmission errors lead to a re-establishment of synchronization.

Method of link word synchronization

A method for managing data traffic in nodes in a fabric network, each node having internally-coupled ports, follows the steps of establishing a managed queuing system comprising one or more queues associated with each port, for managing incoming data traffic; and accepting or discarding data directed to a queue according to the quantity of data in the queue relative to queue capacity. In one preferred embodiment the managed system accepts all data directed to a queue less than full, and discards all data directed to a queue that is full. In some alternative embodiments the queue manager monitors quantity of data in a queue relative to queue capacity, and begins to discard data at a predetermined rate when the quantity of queued data reaches the threshold. In other cases the queue manager increases the rate of discarding as the quantity of queued data increases above the preset threshold, discarding all data traffic when the queue is full.
