Quality of Service and Bandwidth Management

Integrated Session Border Controller (SBC) for the Cisco ASR 1000 Series Routers provides Quality of Service (QoS) and bandwidth management features to assure quality end-to-end connection for real-time voice, video, and multimedia traffic. The packet marked for higher priority is delivered faster than non-prioritized packets. The Cisco ASR 1000 Series Aggregation Services Routers support QoS functions such as Low Latency Queueing (LLQ), Class-Based Weighted Fair Queueing (CBWFQ), and shaping at the subinterface level.

At the SBC level, the data border element (DBE) has different packages to enhance QoS and these packages are described in this chapter. For a complete description of commands used in this chapter, refer to the Cisco IOS Integrated Session Border Controller Command Reference.

H.248 Traffic Management Package Support

The DBE supports the sustained data rate (tman/sdr), maximum burst size (tman/mbs), and policing (tman/pol) properties of the ETSI TS 102 333 Traffic Management (Tman) package.1 Support of these tman properties allows additional pinhole programming in the Tman package to inform the DBE how to police media and signaling flows. These tman properties can be assigned to both media and signaling flows.

The DBE performs asymmetric policing. Asymmetric policing allows the MGC to impose different flow policing on traffic traveling in each direction on the same stream. For example, traffic traveling from the subscriber side to the DBE can be policed independently of traffic from the network core to the DBE.

Asymmetric policing is accomplished by allowing the tman/pol property to be specified separately for the two sides of a gate, which typically might be the access (subscriber) side and the back bone side. The tman/pol property can be specified as ON, OFF, or Absent on either the access side or the back bone side
