Multi-Protocol Label Switching (MPLS) in 21st Century Telecommunications Networks
Book Now - 3 Delivery Methods Available:Scheduled Online Onsite
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
