Total QoS training course contents

  • What is QoS
  • QoS and CoS, throwing bandwidth at the problem, Best effort services, Differentiated services, Integrated services, guarantees, the need for QoS, IETF working groups.

  • Application issues
  • Video, Voice, other applications, Jitter, delay, packet loss. Flows, per flow and per aggregate QoS, Stateful vs. stateless QoS, applications vs. network QoS.

  • “Traditional” IP QoS
  • The TOS field and precedence, the obsolete OSPF use of the TOS field, TCP congestion avoidance.

  • Queuing
  • Where to use queuing, FIFO, Priority queuing, Custom queuing, Weighted Fair Queuing, CBWFQ, PQWFQ, LLQ, RED and WRED.

  • DiffServ
  • Architecture, DSCP, CU, packet classification and marking, meters and conditioners, Bandwidth brokers and COPS, Per Hop Behaviours, best effort PHB, Assured Forwarding PHB, Expedited forwarding PHB, Network Based Application Recognition (NBAR).

  • Layer 2 issues
  • Fragmentation and interleaving, compression (codecs, MPEG formats, header compression…), 802.1p, Subnet bandwidth management, Bandwidth allocators and requestor modules, the use of MPLS, traffic engineering, traffic shaping.

  • RSVP
  • What is RSVP? architectures, paths, path messages, reservations, traffic specifications, tear downs, guaranteed and controlled load, token buckets, Call Admission Control in voice networks, gatekeepers.

  • Other issues
  • Policy based routing, the Resource Allocation Protocol, QoS management tools, baselining networks, design issues, QoS in IPv6, QoS and multicasts.
