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.
