Info

ATM Option • The source unit can transmit cells at a rate less than the negotiated PCR if required, or stop transmitting cells for short periods of time. • Associated ITU QoS class: 1. Unspecified Bit Rate (UBR) • A “best effort” service for use in applications where the traffic flow can be regulated by a network with flexible resource requirements. • Should be selected for applications that do not need to operate under controlled delay and delay variation conditions, e.g. file transfer, email, banking transactions and Telnet. • Performance parameter objectives are determined internally by the application, and do not need to be constant during the duration of the connection. • PCR definition is optional, but the Peak cell rate parameter is available for information purposes. • Does not ensure a specific level of traffic service, Cell Loss Ratio (CLR) or Cell Transfer Delay (CTD). If congestion control is required, it is handled at a higher network layer. • Associated ITU QoS class: U or 0 (Unspecified). Real-time Variable Bit Rate (RT-VBR) • A service for real-time applications that are highly sensitive to delays and delay variation, but where traffic is bursty and must be transmitted at a varying rate, e.g. voice and video. • Should be selected for any real-time application that could benefit from variable rate transmissions, and tolerate or recover from a small Cell Loss Ratio. • Can support statistical multiplexing of traffic from multiple sources in real time. • Bandwidth needs are defined using the Peak cell rate, Sustainable cell rate (SCR) and Maximum burst size (MBS) in cells parameters. • Associated ITU QoS class: 1. Non-real-time Variable Bit Rate (NRT-VBR) • A service for applications with bursty traffic that do not operate in real time and cannot tolerate a high Cell Loss Ratio, e.g. Frame Relay interworking, airline reservations. • Can support statistical multiplexing of traffic from multiple sources. • Delays and delay variations are not critical to this category. • Bandwidth needs are defined using the Peak cell rate, Sustainable cell rate (SCR) and Maximum burst size (MBS) in cells parameters. • Associated ITU QoS class: 2 or 3. 1-12 Memotec Inc.
1.3 ATM Support on the NetPerformer Product Overview The ATM option is sold under special license only, and requires installation of an ATM product key on every NetPerformer unit in the ATM application. The ATM option can be installed on the following NetPerformer products only: • SDM-9360, SDM-9380 or SDM-9585: Must be running NetPerformer V9.0.0 or higher and NetPerformer Signaling Engine version 4.0.8 or higher. These products support both ATM AAL1 and AAL5. Refer to “ATM Protocols and AAL Service Classes” on page 1-4. • SDM-9230: Must be running NetPerformer V10.1 or higher. This product supports ATM AAL5 only. With the ATM option, a customer can access different network services via ATM from a single unit using a T1/E1 card installed on that unit. Figure 1-3 illustrates the many ways that the NetPerformer can provide ATM access.
