ATM Option 1.2.8 Service Categories - ESI: End System Identifier. A globally unique identifier that is similar to a MAC address. - SEL: Selector. A one-byte field that can be used by the end system to discriminate between different services. This field is not used for ATM routing purposes. ILMI Address Registration AESA addresses are not completely predefined. Part of each address is defined by the network manager, and part of it comes from the switch. The complete address is built using ILMI address registration. NOTE: This address registration process is not used for E.164 addresses. When the end system connects to the switch, the 13-byte prefix from the switch is concatenated to a 7-byte user part defined on the end system. The prefix is composed of the AFI, DCC/ICD and HO-DSP fields, while the user part contains the ESI and SEL. The called and calling party numbers (or information elements) that are used during call setup may be in either native E.164 or AESA address format. • With E.164 native, the phone-number like address is encoded using IA5 characters, where (as for ASCII) digit 0 = 30, digit 1 = 31, digit 2 = 32, and so on. For example, the address 18005551000 would be encoded as: 3138303035353531303030 • As mentioned earlier, E.164 addresses can also be imbedded in an AESA address. In this case the called/calling party information element indicates that the address type is AESA and not E.164. The AESA address contains the E.164 address in its prefix. The following shows how the previous example would be encoded in an imbedded E.164 AESA address: Field AFI E.164 HO-DSP ESI SEL Value 45 000018005551000F 00000000 000000000000 00 Table 1-1: Example of an imbedded E.164 AESA address Service Categories are a means of characterizing the way ATM traffic should flow through the network in order to meet bandwidth requirements specific to the type of ATM application used. Each service category is based on a combination of cell rate pacing, Quality of Service (QoS) and traffic priority characteristics. 1-10 Memotec Inc.
NOTE: Service categories can be defined on the SDM-9230 only. Product Overview Four service categories have been defined in the ATM networking standard: • Constant Bit Rate (CBR), described in the next section • Unspecified Bit Rate (UBR), on See “Unspecified Bit Rate (UBR)” on page 12. • Real-Time Variable Bit Rate (RT-VBR), on See “Real-time Variable Bit Rate (RT- VBR)” on page 12. • Non-Real-Time Variable Bit Rate (NRT-VBR), on See “Non-real-time Variable Bit Rate (NRT-VBR)” on page 12.. NOTE: Service categories govern the transmission of traffic from the NetPerformer to the ATM switch. They do not pertain to the NetPerformer transmitting via PVCR, ATM or other transport method to another NetPerformer. Constant Bit Rate (CBR) Figure 1-2: The Service Category Environment • A service for connections that require a static amount of bandwidth that is continuously available during the entire duration of the connection. • Should be selected for real-time applications that cannot work properly if there are large variations in the transmission delay, e.g. voice, video and circuit emulation. • The required amount of bandwidth is defined by the Peak cell rate parameter on the logical connection (PVC or SVC). • Once the connection is established, the network ensures the negotiated ATM layer QoS to all cells. This means that the source unit is able to transmit cells at the PCR at any time and for any duration, with QoS commitments fully maintained. Memotec Inc. 1-11
