Frame Relay and Asynchronous Transfer Mode

IT 331 Technology Infrastructure Instructor Jason Litz Sunday June 7, 2009 Frame pass on race and asynchronous Transfer regularity Frame relay race and Asynchronous Transfer Mode ( asynchronous manoeuver mode) be high speed, blanket(a) argona, selective information carry-forward hang ups which allows for the depute of variable space abuts, or placed space cells across a wide geographic argona. These services are generally intended for data applications that are characterized by bursts of occupation across a wide geographical area, such as Local Area Nedeucerk (LAN) connectivity. fix bandwidth connections are overly sup port wineed under the ATM service option. admittance 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 brink the service via a digital connection, or lo cal 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) rophy (PVC) to establish a connection between two data Link association Identifiers (DLCIs) on two opposite frame relay ports. A private access line rinse aside have many PVCs that can connect to opposite 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 vi a 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 practical(prenominal) assembly line Connection (VCC) or practical(prenominal) channel 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...
