Introduction to MPLS
Course Overview
This course provides a basic understanding of the
configuration, communications, and management of TCP/IP and
its associated protocols.
This course introduces students to the main concepts of OSPF
and BGP. The growth of internetworks has put them beyond
the scability limits of distance vector routing protocols
such as RIP and IGRP to the extent that only link state
routing protocols such as OSPF and IS-IS will suffice. Link
state protocols are more scalable, more reliable, and offer
faster convergence. All of these features are becoming
essential for the scalable multimedia networks of today.
The course introduces policy-based QoS architecture which
supports infrastructure for delivering QoS based
applications and the emerging trends in IP QoS. It explains
the techniques, principles and technology associated with
implementing IP Quality of Service (QoS). The IETF`s
Integrated Services standard and accompanying protocols such
as RSVP, RTP and RTCP are described, and how RSVP is used as
a QoS signalling protocol to request a certain QoS is
covered. This course describes the IETF`s Differentiated
Services standard and how it can be used to provide QoS on a
per-hop basis, and explains how IntServ and DiffServ are
used to provide IP QoS support in routers.
Key Benefits
Students will gain a solid understanding of TCP/IP with
emphasis on use within the telecommunications environment.
Course Pre-Requisites
Students should have a basic understanding of TCP/IP and IP
Networking.
Who Should Attend?
This course is designed to address the needs of the
telecommunications industry by introducing its Engineers
with the TCP/IP protocol and the elements within it that
will be utilised within the telecommunications networks
deploying VoIP, IMS, 3GPP, MPLS, and other
telecommunications technologies that is employing the IP
protocols.
