Training Course Description:
Carriers have offered connectivity services based on traditional TDM,
Frame Relay and ATM for many years. However, the cost of operating
separate networks to provide each of these services, as well as the
need to sell higher bandwidth services than can be offered with these
traditional networks, is forcing them to move to newer, more cost
effective technologies, namely Ethernet, IP and MPLS. Ethernet and IP
have allowed networks to deliver high bandwidth and new services with
greater flexibility, while MPLS has allowed these new services to
become more "carrier-class", offering the connection-oriented
behaviour, quality of service, and reliability normally associated
with traditional technologies. Recently, there has been increased
interest in Layer 2 MPLS based services, which support LAN and legacy
traffic, and are lower cost and simpler to manage. Virtual Private LAN
Service (VPLS) is a fast growing Layer 2 MPLS based service that
offers multi-point connectivity; making enterprise LANs in multiple
sites appear as if they are on the same LAN.
This course provides a fast overview of VPLS, how it works, how it can
be deployed within a carrier network and what benefits to carrier and
user that it provides.
When you have completed this course you will be able to
- Describe how VPLS functions and
its major benefits
- Describe how it can be deployed
using Ethernet and MPLS
- Compare its operation to
alternatives
- Examine example deployments for
delivery of next generation services
