Sample text

With the MPLS enhancement and the new pseudowire-based VPN service, the service provider can now deploy different types of services for many customers in a single converged backbone network using IP/MPLS technology. The IP/MPLS VPN network has the following advantages: • Cost Efficiency — It eliminates the requirement for service providers to build separate networks for different types of services. All services are shared in the same backbone infrastructure. Using an IP/MPLS network with Gigabit Ethernet or 10 Gigabit Ethernet Layer 2 infrastructure significantly reduces the cost compared to the legacy technologies like ATM and FR.

These innovations allow service providers to meet the evolving needs of their customers by providing multiple services using a single converged network. CHAPTER 1 ■ BU I LDI NG C ON V E RGED SE RV IC E N E T WOR K S W I T H IP/ M PL S V PN T E C H NO LO GY 17 IP/MPLS VPN Multi-Service Network Overview 2 An IP/MPLS VPN multi-service network provides the capability of building a converged reliable network supporting many different types of services to many different customers. The network uses MPLS pseudowires to connect Virtual Private Network (VPN) member routers in the core network.

The IP/MPLS VPN-based multi-service network fulfills all the requirements above, and therefore many service providers and enterprises worldwide select it as the networking technology of choice. 2 IP/MPLS Layer 2 VPN Services The previous chapter introduced the challenge for service providers to provide multiple types of services to customers with a converged high-performance and cost-efficient network. IP/MPLS pseudowire-based VPN provides a solution for these service providers. CHAPTER 2 ■ I P/ M PL S V PN M U LT I-S E RV IC E N E T WO R K OV E RV I E W 21 A service provider can offer two choices for VPN services: the Layer 2 approach or the Layer 3 approach.
