摘要： A Resource Reservation System includes a Token Generation Unit (TGU) which generates and circulates among nodes of a communications system a Slotted Token (SLT) message having sub-fields to carry identification number for each input port in a node and the resource available for each input port. On receiving the message the Resource Control Unit (RCU) in each node can write port identification number, available resource in appropriate sub-fields of the SLT message, and reserve resources in other nodes by adjusting information in the sub-field associated with the other nodes.

摘要： The transport protocol for communicating between general purpose processors acting as contact points and network processors in a packet processing environment such as Ethernet is provided. In such an environment, there is at least one single control point processor (CP) and a plurality of network processors (NP), sometimes referred to as blades. A typical system could contain two to sixteen network processors, and each network processor connects to a plurality of devices which communicate with each other over a network transport, such as Ethernet. The CP typically controls the functionality and the functioning of the network processors to function in a way that connects one end user with another, whether or not the end user is on the same network processor or a different network processor. There are three types of communication provided; first, there is communication generally referred to as control services and normally there will be only one pico processor which operates as a GCH (guided cell handler) and only one that operates as a guided tree handler (GTH). A path is provided for the controls to the GCH and the GTH commands, and a separate path is provided for the data frames between the GDH's (general data handler) and the CP.

摘要： A method and system are disclosed for allocating data input bandwidth from a source link to a plurality of N data queues each having a variable occupancy value, Qi(t), and a constant decrement rate, Di, where i designated the ith queue among the N queues. First, a threshold occupancy value, T, is designated for the N queues. During each time step of a repeating time interval, &Dgr;t, the occupancy value, Qi, is compared with T. In response to each and every of said N data queues having occupancy values exceeding T, pausing data transmission from the source link to the N data queues, such that overflow within the data queues is minimized. In response to at least one of the N data queues having an occupancy value less than or equal to T, selecting one among the N data queues to be incremented, and incrementing the selected data queue, such that underflow of the selected queue is minimized. In the context of scheduling one cell per time step, the value of T is one. Furthermore, the method of the present invention guarantees that output port occupancy shall never, in that context, exceed two cells.

摘要： Computers are caused to provide a hash table wherein each entry is associated with a binary key and indexed by a selected portion of a hash value of the associated key, and points to a data structure location for storing non-selected portions of, or the entire hash value of, the binary key, and action data corresponding to the value of the binary key. Content addressable memory entries store a binary key, or a value unique to it, and an association to a corresponding action. Pointers to the data structure use selected portions of binary key hash values as an index when not selected portions of hash values of other binary keys, and associations are established between CAM entry and associated data structure locations when selected portions of the hash values of the binary keys are the same as selected portions of hash values of one or more other binary keys.

摘要： An instruction memory system is shared by a plurality of processors and the system utilizes an increased bandwidth to support the combined number of processors. The total instruction address space is divided into code segments according to the disjoint tasks to be performed. The instruction codes of each processor are consolidated into one copy for control instructions and duplicate copies for other disjoint tasks such as inbound requests and outbound requests that have greater processor contention. Interleaving of the memory arrays for certain disjoint tasks serves to provide a larger number of instructions for these tasks. The system utilizes arbiters to receive all disjoint tasks and to control multiplexors that send addresses to memory arrays.

摘要： A structure and technique for preventing collisions using a hash table in conjunction with a CAM to identify and prevent collision of binary keys. A portion of the hash value of a binary key, which does not collide with a portion of the hash value of any other reference binary key, is used as an entry in the hash table. If two or more binary keys have identical values of the portions of the hash values, each of these binary keys are stored in their entirety, in the CAM. The key in the CAM provides a pointer to a data structure where the action associated with that binary key is stored. If the binary key is not found in the CAM, the binary key is hashed, and a specific entry in the hash table is selected using a portion of this hash value.
