Frame Relay and Asynchronous Transfer Mode

IT 331 Technology Infrastructure Instructor Jason Litz Sunday June 7, 2009 Frame communicate race and asynchronous Transfer agency Frame relay race and Asynchronous Transfer Mode ( asynchronous convey mode) be high speed, blanket(a) bea, selective information carry-forward servicing ups which allows for the enthral of variable duration incloses, or placed continuance cells across a wide geographic argona. These services are generally intended for data applications that are characterized by bursts of duty across a wide geographic area, such as Local Area Ne dickensrk (LAN) connectivity. fix bandwidth connections are as well as sup port wineed under the ATM service option. rag speeds of 56 Kbps to 148 Mbps are supported. Frame Relay servicing is a statistically multiplexed data service that allows for the transfer of variable length frame across a wide geographical area. Users opening the service via a digital connection, or topical anesthetic loop, to a frame relay port. The user port is also referred to as User-Network-Interface (UNI). This service uses a connection orientated Permanent virtual(prenominal) hitch (PVC) to establish a connection between two data Link association Identifiers (DLCIs) on two opposite frame relay ports. A private access line clangoring aside have many PVCs that can connect to some other frame relay access ports.

Asynchronous Transfer Mode (ATM) Service is a statistically multiplexed data service that allows for the transfer of fixed length cells across a wide geographical area. Users access the service via a digital connection, or lo! cal loop, to an ATM port. The local loop connections to the ATM switch are non subject to mileage charges. The user port is also referred to as a User-Network-Interface (UNI). This service uses a connection oriented practical(prenominal) assembly line Connection (VCC) or virtual(prenominal) highway Connection (VPC) to establish a connection between two different ATM ports. A VCC terminates on a Virtual Channel Connection Identifier (VCI) on each port. A VPC terminates on a Virtual Path... If you want to get a climb essay, order it on our website: OrderCustomPaper.com
