Detailed Description

Structure describing an ATM traffic contract for a Virtual Connection (VC).

Structure is used to specify the requested traffic contract for a VC to the IxAtmSch component using the ixAtmSchVcModelSetup interface.

These parameters are defined by the ATM forum working group (http://www.atmforum.com).

Note:
Typical values for a voice channel 64 Kbit/s
  • atmService IX_ATM_RTVBR
  • pcr 400 (include IP overhead, and AAL5 trailer)
  • cdvt 5000000 (5 ms)
  • scr = pcr

Typical values for a data channel 800 Kbit/s

  • atmService IX_ATM_UBR
  • pcr 1962 (include IP overhead, and AAL5 trailer)
  • cdvt 5000000 (5 ms)
