SNT Network Service Group Definitions (NETGROUP)

The
MICS Network Analyzer
supports the data element NETGROUP in each of the six files available for accounting:
rm
  • SNTNAC - NCP Network Accounting File
  • SNTNSS -
    NetSpy
    Terminal File
  • SNTPSU - NPM User Activity File
  • NVSNSA - NLDM Session Accounting File
  • NVSNSC - NLDM Session Connectivity File
  • NVSRTM - NLDM Response Time File
NETGROUP is used to classify a network session according to its service requirements or its configuration characteristics. The classifications permit differential billing that is based on service requirements or configuration. For example, an enterprise may want to charge a premium for sessions which receive a high transmission priority. Sessions with a transmission priority greater than 0 could be charged at the rate of 125% of the normal charge for character traffic. All other sessions would be charged at the standard billable rate (that is, 100%).
Defining network service groups is a two-step process. First, each network group is identified by a network group number (an identifying number in the range 1-256), a service factor (a value that identifies the rate at which session charges will be assessed), and a description. This information is recorded in prefix.MICS.PARMS(NETGROUP), described in the Network Service Group Definition (NETGROUP) section. Then a routine is coded to set NETGROUP in the appropriate files so it can be used for network accounting. This routine, called NETGPRT (also a member of prefix.MICS.PARMS), is discussed in the Network Service Group Exit Routine (NETGPRT) section.
