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.

Why Choose Us

SNT trainers score an average of over 90% on the three main areas of:
  • Ability to teach
  • Technical knowledge
  • Answering questions
“Excellently presented by a very knowledgeable and enthusiastic trainer.” P.D. General Dynamics

We limit our maximum class size to 8 delegates; often we have less than this. This ensures optimal interactivity between delegates and instructor.
"Excellent course. The small class size was a great benefit…" M.B. IBM

We write our own courses; courseware does not just consist of slides and our slides are diagrams not bullet point text. A typical chapter provides clearly defined objectives with a chapter overview, slides with text underneath, a quiz at the end to check the learning of the students. Hands on exercises are at the end and are used to reinforce the theory.
