ALCATEL-LUCENT SPECIFIC OVERVIEW
The following features are supported:
• Supports QoS on Frame-Relay Interface/Sub-Interface (PVC based)
• QoS marking based on the FR fields (FECN, BECN, DE)
• Strict priority queuing within PVC
• Classification based on the DLCI
• Frame-Relay fragmentation (See “LFI Configuration on FR” section in Link
Fragmentation and Interleaving chapter for more details on link fragmentation and
interleaving on FR)
• Three levels of QoS policy can be configured on the FR interface/sub-interface in
the egress direction. In the ingress direction, four levels of QoS policies can be
configured.
• The QoS policy attached to tunnel interface (going through the FR interface), will
have the restriction of two levels of hierarchical queuing. Because, in physical
interface, maximum four levels HQ is possible (including DLCI class). Whenever
the tunnel policy will be added to the physical interface policy, it will add another
two levels (i.e. one for DLCI class, another for tunnel class).
