A method of optimising a service rate of a buffer in a computer system having memory stores of first and second type is described. The method selectively services the buffer by routing data to each of the memory store of the first type and the second type based on read/write capacity of the memory store of the first type.

Method and system for accelerating storage of data in write-intensive computer applications

A method and system for determining short-timescale traffic rates from time stamped packet data is described. The method and system provides for the calculation of traffic rates, or bandwidths, in bits-per-second or packets-per-second over short time windows, using time-stamped packet records as input.

Method and system for determining short-timescale traffic rates from time-stamped packet data

Embodiments of the invention relates to bandwidth requirements within a packet data network. A method and system for analysing traffic is described herein. The method may utilises an estimation of a concave hull function of the arrived traffic within the buffer. The use of such a concave hull representation may allows for more efficient data processing and for a direct measurement of desired service rates for differing predetermined control parameters.

Method and apparatus for calculating bandwidth requirements

A methodology and network tool for evaluating one-way directional delays in a packet network is described. The invention provides for a discrimination of the directional components of the delay experienced by packets travelling between nodes in a network. This identification of the directional delay component assists in an understanding of network behaviour and can be represented on a graphical user interface. Such methodologies are achieved without requiring clock synchronisation between clocks at each of the nodes.

Delay measurements in network traffic

The invention relates to a method and apparatus for measuring and recording traffic at nodes in a data transmission network. In particular the invention provides a method of accurately counting individual activities of traffic at individual nodes. The invention is carried out in hardware by using a counter or number of counters which count individual activities of traffic on a preset activity condition being sensed at a node. The invention has the advantage that accurate measurement of traffic at a node is achieved. The invention is also easy to implement in hardware and overcomes the problems inherent in present software solutions.
