Index Generic cell rate algorithm

The generic cell rate algorithm (GCRA) is a leaky bucket-type scheduling algorithm for the network scheduler that is used in Asynchronous Transfer Mode (ATM) networks. [1]

Asynchronous transfer mode

Asynchronous transfer mode (ATM) is, according to the ATM Forum, "a telecommunications concept defined by ANSI and ITU (formerly CCITT) standards for carriage of a complete range of user traffic, including voice, data, and video signals".

ATM Forum

The ATM Forum was founded in 1991 to be the industry consortium to promote Asynchronous Transfer Mode technology used in telecommunication networks; the founding president and chairman was Fred Sammartino of Sun Microsystems.

Field-programmable gate array

A field-programmable gate array (FPGA) is an integrated circuit designed to be configured by a customer or a designer after manufacturing hence "field-programmable".

ITU-T

The ITU Telecommunication Standardization Sector (ITU-T) is one of the three sectors (divisions or units) of the International Telecommunication Union (ITU); it coordinates standards for telecommunications.

Jitter

In electronics and telecommunications, jitter is the deviation from true periodicity of a presumably periodic signal, often in relation to a reference clock signal.

Leaky bucket

The leaky bucket is an algorithm based on an analogy of how a bucket with a leak will overflow if either the average rate at which water is poured in exceeds the rate at which the bucket leaks or if more water than the capacity of the bucket is poured in all at once, and how the water leaks from the bucket at an (almost) constant rate.

Network interface controller

A network interface controller (NIC, also known as a network interface card, network adapter, LAN adapter or physical network interface, and by similar terms) is a computer hardware component that connects a computer to a computer network.

Network scheduler

A network scheduler, also called packet scheduler, queueing discipline, qdisc or queueing algorithm, is an arbiter on a node in packet switching communication network.

Network-to-network interface

In telecommunications, a network-to-network interface (NNI) is an interface that specifies signaling and management functions between two networks.

Scheduling (computing)

In computing, scheduling is the method by which work specified by some means is assigned to resources that complete the work.

Token bucket

The token bucket is an algorithm used in packet switched computer networks and telecommunications networks.

Traffic contract

If a service (or application) wishes to use a broadband network (an ATM network in particular) to transport a particular kind of traffic, it must first inform the network about what kind of traffic is to be transported, and the performance requirements of that traffic.

Traffic policing (communications)

In communications, traffic policing is the process of monitoring network traffic for compliance with a traffic contract and taking steps to enforce that contract.

Traffic shaping

Traffic shaping is a bandwidth management technique used on computer networks which delays some or all datagrams to bring them into compliance with a desired traffic profile.

UPC and NPC

Usage Parameter Control (UPC) and Network Parameter Control (NPC) are functions that may be performed in a computer network.

User–network interface

In telecommunications, a User Network Interface (UNI) is a demarcation point between the responsibility of the service provider and the responsibility of the subscriber.

Virtual circuit

A virtual circuit (VC) is a means of transporting data over a packet switched computer network in such a way that it appears as though there is a dedicated physical layer link between the source and destination end systems of this data.
