Title: Packet age control in computer networks
Inventor: BRYANT STEWART F
IPC: H04L12/54
Filed: 1991-06-04
Abstract: A packet forwarding node for a computer network comprises at least one receiving module and at least one output module including package list means (21) for maintaining a list of packets to be transmitted therefrom. The time for which a packet remains in the node is determined by grouping the packets into groups or "buckets" which are created at regular intervals, each bucket containing packets arriving within the same time interval, and keeping track of the age of each bucket. A bucket counter (33) counts the total number of buckets in existence, so indicating the age of the oldest packet. This counter is incremented by 1 at regular intervals and decremented by 1 each time the oldest bucket is emptied (or found to be empty). A bucket list shift register (30) has its contents shifted at each change of time interval, its bottom stage accumulates the number of packets arriving in a time interval, and an overflow accumulator (31) accumulates counts shifted out of its top end. The bucket list shift register may comprise a plurality of sections each of which is shifted at an exact submultiple of the rate of shifting of the previous section, the bottom stage of each section accumulating counts shifted out of the previous section. In an alternative embodiment, bucket boundary markers are inserted into the packet list means at each change of time interval. <IMAGE>

Title: Message routing in a multiprocessor computer system
Inventor: NUGENT STEVEN F
IPC: H04L12/56
Filed: 1991-08-29
Abstract: A parallel processing computer system as in GB 2227341 has an improved architecture for communication of information between nodes. The computer system comprises at least three nodes, each comprising means for processing information and a routing means for routing information between nodes. The routing means allow reservation of a route through the network of nodes. Messages may then be transmitted from an origin node to a destination node over the reserved route. Use of a route reservation system reduces requirements for buffering of information at intermediate nodes on a route, improves message passing latency and increases node-to-node bandwidth. The present invention teaches communication of messages between nodes in a synchronous manner using a common strobe (clock) signal, which is modified by regenerating alternate edges of the signal, in order to eliminate pulse shrinkage of the strobe signal. <IMAGE>

Title: Strain measuring device
Inventor: GIBBS STEPHEN
IPC: F16K37/00
Filed: 1993-02-02
Abstract: In an assembly comprising a (rotary) actuator (16) mounted on a body (12), e.g. of a valve fitted in a pipeline (14), and having a drive shaft (20) to actuate the valve or other driven element within the body, the actuator is mounted on the body (12) by means of a member (18), e.g. a cylindrical mounting stool, which is provided with strain gauges (28) to measure the reaction force acting on the mounting member (18) in response to the output force applied by the actuator. The assembly thus allows the direct derivation of the output torque or thrust of the actuator (16), which is equal and opposite to the reaction force measured by the strain measuring devices (28). The dimensions of the mounting member (18) may be chosen to give the same strain therein as in the drive shaft (20). The strain gauge output signal is damped to remove transients, but the undamped signal may also be used as a measure of vibration in the assembly. <IMAGE>

Title: ATM cell switch
Inventor: JONES TREVOR
IPC: H04L49/111
Filed: 1995-03-16
Abstract: An ATM cell switch comprises a leaky bucket processor arranged to calculate the resultant bucket level for a pair of buckets simultaneously. Each resultant level is measured by calculating the time interval between the reception of two consecutive cells on the same connection. From this measured interval and a predetermined regular bucket increment, the resultant level in the bucket is determined. It is then compared with a predetermined maximum level. If the maximum level will be exceeded, the current cell will either be discarded, or have its Cell Loss Priority changed. The cell switch also has means for processing header data for each incoming cell to determine how it should be handled in the switch.
