The Fibre-Channel flow control mechanism is augmented to facilitate efficient data exchange between Fibre-Channel ports over extended distances. A supplemental buffer mechanism may be maintained as part of an interface to a transport network used to carry Fibre-Channel traffic. The transport network interface makes a remote Fibre-Channel port aware of the augmented local receiver buffer capacity by intercepting certain frames used in link establishment and substituting an enhanced buffer capacity for the local Fibre-Channel port's internal buffer capacity. This technique provides improved throughput and readily accommodates large distances and large frame sizes.

A packet switching system and method are disclosed. The system includes a plurality of input and output ports and an input buffer at each of the input ports. The system further includes an input scheduler associated with each of the input buffers and a centralized memory shared by the output ports. An output buffer is located at each of the output ports and an output scheduler is associated with each of the output ports. Each of the input buffers comprises a plurality of virtual output queues configured to store a plurality of packets in a packed arrangement.

A method of mapping coded data for communication within a network is disclosed. The method includes receiving an 8/10source protocol data stream and converting the data stream into a plurality of 33-bit code groups. Each of the 33-bit code groups contains four bytes of data and one control bit. The method further includes forming a 33-byte block comprising eight of the 33-bit code groups.

A generalized axiomatic definition of information-theoretic similarity is provided for taxonomies that are structured as directed acyclic graph form which multiple terns may be used to describe an object. The definition is adaptable in the presence of ambiguity, as introduced by an evolving taxonomy or classifiers with imperfect knowledge, and two new similarity measures are introduced based on the definitions. A pragmatic implementation is also provided for similarity measures that arc tightly integrated with an object-relational database and scales to large taxonomies and large datasets.

Fiber-Channel links are carried over transport networks such as optical transport networks. In certain embodiments, available transport network capacity is over-subscribed by Fiber-Channel links. This may be accomplished by buffering Fiber-Channel traffic at the ingress of the transport network and selecting frames to inject into the transport network from the buffers. Transport network efficiency can therefore be greatly increased by use of statistical multiplexing. Ready signals from the receiving Fiber-Channel ports may be delayed before being relayed to the transmitting Fiber-Channel ports.

The disclosed embodiments relate to a system and method of applying policies. The method may include identifying a first entity and a first relationship, the first relationship defining an attribute related to the first entity. Additionally, the method may include identifying a policy associated with the first entity and the first relationship and applying semantics to determine a degree of relatedness between the first entity and a second entity. Further, the method may include applying the policy to a second relationship that defines an attribute related to the second entity if the degree of relatedness between the entity and the second entity is within a range of values.
