Training Course Outline
Course Duration:
2 day
Training Course Description:
This course provides an understanding of how MPLS works, its
advantages and limitations and how it can be deployed to provide
effective services over a 21st Century converged network. It will
provide a detailed understanding for implementers, designers, managers
and infrastructure engineers that need to plan, implement and use the
new generation of networks and services.
The next generation of telecommunications networks will deliver
broadband data and multimedia services to users. The Ethernet
interface is becoming the interface of preference for user computers,
IP Phones, Digital IP Television and network servers within the
network itself. The network infrastructure will deliver these high
performance IP services over Switched infrastructures deployed using
Multi-Protocol Label Switching (MPLS).
MPLS is a radically new approach to delivering IP services and must be
built on an IP routed infrastructure. However by deploying switching
hardware it becomes possible to deliver quality of service by
bypassing queues in routing functions and switching essentially in OSI
layer 2. Once constructed MPLS networks can be used to deliver
emulation services to provide customers with more traditional circuits
provisioned over interfaces such as E1, Frame Relay, ATM and STM1
which in reality are provided emulated over MPLS running over Gigabit
Ethernet infrastructures.
When you have completed this course you will be able to:
- Describe the basic function of
MPLS
- Select the appropriate options and
mechanisms for Label Distribution
- Compare the efficiency of routed
and MPLS switched options for QoS networks
- Build infrastructures using MPLS
over different physical infrastructures
- Provide reliability by deploying
the re-routing options in the event of failures
- Deliver high bandwidth MPLS
services for OSPF and BGP4 routed networks
- Engineer Traffic on MPLS services
- Provide Emulated services over
MPLS infrastructures
Prerequisites:
Delegates should have a solid understanding of IP and WAN
technologies.
