Scalable Services on an MX Series Router Overview


Service providers are increasingly evaluating products to offer their customers value-added services such as network-based security, carrier grade NAT (CGN), and deep packet inspection (DPI). With MX Series 3D Universal Edge Routers, service providers can offer integrated value-added services for their subscriber base beyond basic Broadband Network Gateway functions in traditional deployments. Example: Deploying Value-Added Subscriber Services with MX Series Routers covers the versatile Broadband Network Gateway functionality on the MX Series router. The example does not test the MX Series router to its limits, but it describes multiple services such as Point-to-Point Protocol over Ethernet (PPPoE) subscribers, CGN with dual-stack lite (DS-Lite) subscribers, and dynamic application awareness with DPI deployed on a single router. Service providers benefit from the MX Series routers’ versatile architecture, which enables value-added services on the Broadband Network Gateway router, reducing the need for external appliances and realizing savings in operational expenses and capital expenses. MX Series routers deliver large-scale performance using the Modular Port Concentrator (MPC) and the MultiService-Dense Port Concentrator (MS-DPC).

In residential broadband networks, triple-play networks provide residential voice and Internet data services that deliver an experience based on a converged IP infrastructure. New subscribers must be provisioned on a daily basis, while existing subscribers can make changes to their service subscriptions. There is a significant amount of subscriber management activity on a daily basis. Subscribers are provisioned with PPPoE or Dynamic Host Configuration Protocol (DHCP) models. A Broadband Network Gateway solution must support all the aspects of subscriber configuration and provisioning in a simple and scalable manner with support for automation and minimal manual configuration. Subscriber characteristics are defined based on service subscription and network resources such as bandwidth and quality of service (QoS) and are provisioned based on the service type.
