In configuration management, a baseline is an agreed description of the attributes of a product, at a point in time, which serves as a basis for defining change. [1] A change is a movement from this baseline state to a next state. The identification of significant changes from the baseline state is the central purpose of baseline identification ...
Baselining is a method for analyzing computer network performance. The method is marked by comparing current performance to a "baseline" derived from past performance. If the performance of a network switch or other network components is measured over a period of time, that performance figure can be used as a comparative baseline for configuration changes.
In data networking and transmission, 64b/66b is a line code that transforms 64-bit data to 66-bit line code to provide enough state changes to allow reasonable clock recovery and alignment of the data stream at the receiver.
The binary signal is encoded using rectangular pulse-amplitude modulation with polar NRZ(L), or polar non-return-to-zero-level code. In telecommunications, a non-return-to-zero (NRZ) line code is a binary code in which ones are represented by one significant condition, usually a positive voltage, while zeros are represented by some other significant condition, usually a negative voltage, with ...
Network calculus is "a set of mathematical results which give insights into man-made systems such as concurrent programs, digital circuits and communication networks." [1] Network calculus gives a theoretical framework for analysing performance guarantees in computer networks.
Quality of service (QoS) is the description or measurement of the overall performance of a service, such as a telephony or computer network, or a cloud computing service, particularly the performance seen by the users of the network.
In the context of computer networks, packet jitter or packet delay variation (PDV) is the variation in latency as measured in the variability over time of the end-to-end delay across a network. A network with constant delay has no packet jitter. [11] Packet jitter is expressed as an average of the deviation from the network mean delay. [12]
Perceived baseline versus historical baseline of an organism. A shifting baseline (also known as a sliding baseline) is a type of change to how a system is measured, usually against previous reference points (baselines), which themselves may represent significant changes from an even earlier state of the system that fails to be considered or remembered.
