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
compressionâ¦), 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.
