CSMA/CARP is similar in nature to the CSMA/CD Channel access method used in Ethernet networks, but CSMA/CARP provides no detection of network collisions. Instead of detecting network collisions, CSMA/CARP attempts to avoid collisions by using a system of transmission priorities. When a station wants to transmit on a CSMA/CARP network it first listens for network traffic and if the medium is clear instead of immediately transmitting as a station would in CSMA/CD it waits a predefined amount of time. This waiting period is called the interframe spacing (IFS) and it varies by the type of data being transmitted. High priority data will transmit almost immediately whereas lower priority data such as polling will have a longer IFS. This system allows CSMA/CARP to avoid many collisions that would occur if it was not used. In addition to having a different IFS per priority, a station in a CSMA/CARP network will add a "random backoff" to its waiting period, to reduce the collision probability between stations that have to transmit packets in the same priority. == Applications == * The IEEE 802.11 standard uses CSMA/CARP * The ITU-T G.hn standard, which provides high-speed local area networking over existing home wiring (power lines, phone lines and coaxial cables) includes support for CSMA/CARP, although only during certain periods of time called "Shared Transmission Opportunities" (STXOP). During the rest of the time, G.hn uses a time division multiple access channel access method to ensure quality of service. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Carrier sense multiple access with collision avoidance and resolution using priorities」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
