Resilient Packet Ring

Global growth in IP-based traffic has placed a tremendous load on networks and service providers are seeking solutions to streamline and optimize network traffic. Service providers are looking for new “transport” solutions that will enable them to deliver efficient and cost-effective service.

UTStarcom’s NetRing® TN715 product provides the much needed RPR functionality in the Optical network.

The key applications enabled by TN715 include:

Data transport for Core network
The TN715 enables the data transport ring in the core network. Each core router or switch requires either one interface (GE/XGE) or dual interfaces (for protection) to connect each other. The RPR ring supports data transport, protection, traffics distribution and management among the core routers or switches.

Traffic aggregation from broadband access node to the core
More and more subscribers connect to the network via different broadband access technologies like xDSL, xPON and Ethernet. Broadband access network provides provide high bandwidth today with sample ranges from 100Mbit/s for residential customer to 1000Mbit/s for enterprises. Legacy data networks are ineffective in transporting this level of traffic back to the core in a simple, fast & cost effective manner. RPR based data transport solution provides a preferred solution to aggregate traffic from broadband access node to core.

Private data network for IPTV/3G/NGN
High bandwidth services like IPTV, video conference, video phone, IP Surveillance, etc require high quality data networks as provided by the NetRing T715 product., Since the data traffic from these high bandwidth applications have a fixed origination and destination in many cases, these applications can work in a closed data network - the Metro Private Data Network. Legacy metro data networks are not suitable for these new services.

Metro Ethernet Network for enterprise E-Line and E-LAN service
Metro Ethernet Network (MEN) is generally defined as the network that bridges or connects geographically separated enterprise LANs while also connecting across the WAN or backbone network that generally owned by service providers. In enterprise networks, Ethernet enables connectivity to the public Internet and connectivity between geographically separate corporate sites by LAN extension. Ethernet Line (E-Line) and Ethernet LAN (E-LAN) are two of the services enabled. E-Line provides a point-to-point Ethernet Virtual Connection (EVC) between two User-Network Interfaces (UNIs, Subscribers). E-LAN provides a multipoint-multipoint EVC between two or more UNIs. Subscriber data sent from one UNI can be received at one or more of the other UNIs.

RPR is a key technology to provide Metro Ethernet service. In addition to the investment protection advantage, RPR has optimized QoS guarantees within RPR rings.
