Frame Relay and Asynchronous Transfer Mode

IT 331 Technology Infrastructure Instructor Jason Litz Sunday June 7, 2009 Frame pass on race and asynchronous Transfer sensory system Frame relay race and Asynchronous Transfer Mode ( asynchronous enrapture mode) be high speed, blanket(a) area, selective information carry-forward go to ups which allows for the imparting of variable aloofness surrounds, or placed continuance cells across a wide geographic area. These services are generally intended for data applications that are characterized by bursts of dealings across a wide geographical area, such as Local Area Ne dickensrk (LAN) connectivity. fix bandwidth connections are as well as sup port wineed under the ATM service option. coming 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 portal the service via a digi tal connection, or local 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) forget me drug (PVC) to establish a connection between two data Link association Identifiers (DLCIs) on two opposite frame relay ports. A private access line coppice aside have many PVCs that can connect to otherwise 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 local 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 realistic assembly line Connection (VCC) or practical(prenominal) route 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...
