Shaping and Queuing Per-Session Traffic on LNS
The Per Session Shaping and Queuing on LNS feature provides the ability to shape (for example, transmit
or drop) or queue (for transmission later) the traffic from an Internet service provider (ISP) to an ISP
subscriber over a Layer 2 Tunneling Protocol (L2TP) Network Server (LNS). The outgoing traffic is shaped
or queued on a per-session basis.
Shaping and queueing traffic on a per-session basis:
• Helps to avoid traffic congestion and allows the ISP to adhere to the Service Level Agreement (SLA)
established for managing traffic.
• Provides a high degree of granularity for managing traffic on the network. Figure 17-2 is a sample
topology for per-session shaping and queuing on an LNS.
