Product Brief Unique Interworking Capabilities Ring/mesh interworking allows for enhanced interoperability between the SN 16000 and other network elements, full restoration of working traffic with no loss of ring capacity, and higher network resiliency. Sophisticated circuit management capabilities simplify configuration and management in ring and mesh-based networks, and support both automated and manual provisioning in all topologies. This means that the SN 16000 delivers all the cost savings, operational efficiencies, and competitive benefits of intelligent optical switching without any disruption to existing networks, services, or revenue streams. Service providers can selectively add bandwidth or enable automated features – at a pace dictated by market demand and their own business requirements. Scalability for IP and Multiservice Networks An extremely robust optical layer supports high-density aggregation of new and existing data traffic (ATM, Frame Relay, Ethernet, IP) and simplifies the process of extending high-speed Ethernet services over SONET/SDH networks. SN 16000 modular service interfaces include flexiblerate GigE and 10 GigE, with Ethernet Packet Intelligence (intelligent policing and packet-to-circuit mapping, using Layer 2 VLAN tags and MPLS label information), support for MEF service classes, and unique implementations of ITU-T Ethernet standards (VCAT, LCAS, GFP) to enhance network efficiency and manageability. Multiservice aggregation increases the resiliency of data services, improves capacity utilization, and supports high-bandwidth applications.

BroadLeaf software enables interaction between network layers that allows for dynamic, on-demand bandwidth and unprecedented scalability. New interface modules, line cards, or nodes can be added non-disruptively, in a matter of minutes, to meet rapidly changing end user needs. Intelligent Bandwidth Management Empowered by BroadLeaf and SILVX, the SN 16000 dramatically reduces provisioning times, enhances capacity utilization and traffic engineering, and supports multiple restoration methods across a common infrastructure. Multi-Layer, Multi-Vendor Interoperability A standards-based approach to multi-layer, multi-vendor interoperability has proven to simplify IP/optical integration in multi-vendor environments. Sycamore networking software has demonstrated compliance with the IETF GMPLS and OIF UNI/E-NNI protocols, and supports the ITU-T ASON framework for optical network architecture and other emerging standards. BroadLeaf, the first IP standardsbased optical control plane and the most robust switching software in the industry, is augmented by continuous innovation and enhancement based on years of deployment experience in Tier 1 production networks. Leveraging this intelligent control plane and SILVX, the SN 16000 achieves a level of network and service awareness that enables seamless interoperability with other network elements. Resilient Mesh Restoration Intelligent bandwidth management encompasses resilient mesh protection schemes and per-port configurable Quality of Service (QoS). Mesh restoration options (from 1+1 Path
UPSR/SNCP SN 16000 Integrated BB-DCS/ADM Functionality Protected and Dynamic Source Reroute to Unprotected) work in any network topology and in multiple combinations; and diversely routed circuits ensure network resiliency and survivability, even in the event of multiple, simultaneous failures. Mesh protection and distributed intelligence enable highly customized solutions while improving operational efficiency and profitability. With the SN 16000 platform, service providers can segregate different traffic types to meet service level agreements (SLAs) and offer tiered protection – even a mix of protection within a single service contract. Enhanced Manageability and Security Intelligent optical switching simplifies and enhances the delivery of broadband services. Very short turn-around times for provisioning high-speed services – a matter of minutes – easily accommodate customers’ requirements for flexible connection speeds and time-of-day services. SILVX even makes it possible for service providers to offer premier customers and resellers a ‘do it yourself’ option (i.e., customized network and service views) through an easy-to-use, web-based interface. The SN 16000 supports network partitioning (e.g., OVPN, scheduled bandwidth) and customer-managed sub-networks and services in a controlled, secure environment that protects overall network assets. Communications integrity is assured with security capabilities such as account, password, and session management; excessive authentication retry notification; and extensive audit logging to ensure accountability for user actions. A rich set of optional security features includes RADIUS central authentication and IPsec trusted path support and encryption protection.

Advanced features support a flexible mix of protection schemes and unique, standards-based ring and mesh interworking. The Ultimate in Flexibility and Efficiency For incumbent service providers, technology choices being made now will impact long-term network costs, service differentiation, and revenue growth. Effective solutions for network evolution should leverage existing infrastructure to quickly expand service possibilities – yet provide an open path forward. The SN 16000 does both, empowering service providers to determine the pace of change. Advanced network intelligence ensures maximum flexibility, with support for: n Seamless integration in large, hybrid networks n Cost-efficient, pay-as-you-grow deployment options n Gradual migration to automated operational procedures n Targeted introduction of enhanced features and services n Long-term competitive differentiation and growth Sycamore switching platforms share common networking software (BroadLeaf) and a single management system (SILVX) to further enhance end-to-end manageability and resiliency. From day one and in any topology, deploying the SN 16000 at the network core delivers dramatic reductions in operational cost and complexity, supports interoperability with other technologies and vendors, and forms a robust and scalable foundation for dynamic network infrastructure. 5
