Introduction

introduction ietf diffserv architecture rfc 2475
Introduction –IETF DiffServ Architecture (RFC-2475)
  • The idea: different service levels for packets
  • The service: some significant characteristics of packet transmission in one direction across the network

Examples: bandwidth and latency

a new paradigm for automating the delivery of network quality of service
A New Paradigm for Automating the Delivery of Network Quality of Service
  • Key Takeaways:
    • Simpler QoS deployments – Reduces operator errors
    • Cheaper QoS deployments – Up to 2/3rds reduction in cost
    • Faster QoS deployments – Up to 2/3rds reduction in deployment time
  • Cisco AutoQoS initial focus: QoS for Voice over IP
    • IP Telephony is here!
    • IP Telephony requires QoS
    • QoS deployment can be challenging
    • Cisco AutoQoS makes VoIP deployments simpler, cheaper, and faster
  • Cisco AutoQoS retains 100% customer control over configuration

Cisco AutoQoS - VoIP FrameworkDiffServ Functions Automated
  • Automation and simplification of the existing user interface to expedite deployment of QoS features for VoIP
  • Fine-tuning of AutoQoS generated parameters by user, if desired

Cisco AutoQoS Framework –Network Based Application Recognition

What Applications are running through my network?

  • Benefits
    • Identifies Layer 4 to Layer 7 applications and protocols
      • Stateful & deep packet inspection
    • Protocol Discovery analyzes application traffic patterns in real time and identifies traffic is running on the network
  • Platform Support
    • Cisco 1700, 2600, 3600, 7100, 7200, FlexWan Series Routers
    • Switches: MSFC support on Sup 1a & Sup 2 introduced in Release 12.1(13)E
cisco autoqos framework nbar rtp payload type classification
Cisco AutoQoS Framework –nBAR RTP Payload Type Classification
  • Eases classification of voice and video traffic
    • VoIP, streaming / real time video, audio / video conferencing, Fax Over IP
  • Distinguishes betweenRTP packets based on payload type and CODECS
  • Removes dependencies on UDP Port Range & DSCP markings
cisco autoqos framework percentage based policies
Cisco AutoQoS Framework –Percentage Based Policies
  • Problems
    • Fixed CIR imposes scalability issues
    • Service policies differ by interface, with a wide range of interface bandwidths
  • Solution
    • Configure policies as a percentage of available bandwidth
  • Advantage
    • Increased Scalability & Manageability

Same Policy Map can be applied on multiple interfaces and on interfaces with varying bandwidth

Build Once, Apply Many Policies
