6.3.3 The “Traffic Contract” index card
This index card defines the channel traffic contract parameters. The possible entries depend on
the selected traffic type. The index card contains the following sections:
Fig. O-30 The “Traffic Contract” index card (Channel Editor)
The index card contains the following sections:
Section Meaning
Conformance Definition: Radio button for selecting the conformance definition
None
1
- No conformance definition
CBR.1, VBR.1 ... - Conformance definition, selection depends on traffic type
Info - Information window for conformance definition
Use MBS Activates / deactivates entry of maximum burst size parameter (in
cells) instead of burst tolerance.
Forward/Backward Traffic Des. Contract parameters for forward / backward direction
Peak Cell Rate - Peak cell rate
CDVT peak - Cell delay variation tolerance, referred to the peak cell rate
Sustainable Cell Rate
2
- Sustainable cell rate
Burst Tolerance
2
- Burst-tolerance
Maximum Burst Size
3
CDVT sustained
2
- Cell delay variation tolerance, referred to the sustainable cell rate
Additional action buttons for bi-directional asymmetric channels
4
Forward => Backward Copies the forward parameters to the backward direction
Forward <= Backward Copies the backward parameters to the forward direction
Forward<> Backward Exchanges the forward and backward direction parameters
1 For PVC only (SVC always require conformance definition)
2 Not always available, depends on traffic type
3 This box is only available instead of “Burst Tolerance” if “Use MBS” is activated.
4 See “General” index card; the buttons only affect the relevant index card.
