The Alcatel-Lucent® 7750 Service Router (SR) is the industry leading IP/MPLS based multiservice edge router, is purpose built for and mission-critical enterprise customers, service providers, and cable MSO. It is ideally suited as a backbone node in a larger network or as a WAN layer 3 access point in a layer 2 network. It provides a wide variety Ethernet, SDH/SONET, ATM/CES and TDM interfaces.

Optimized for the delivery of high performance data, voice and video services, the
7750 SR is available in three chassis sizes - 1 slot, 7 slots and 12 slots - all of which offer a wide range of interfaces with unmatched density and service performance.

Leveraging the strength of the Alcatel-Lucent Service Router Operating System (SR OS), the 7750 SR delivers the service flexibility to achieve the service continuity,
service richness and service assurance critical to ensuring customer satisfaction and market leadership.

Key selling points

• Purpose-built platform to enable the efficient and cost-effective delivery of a new generation of differentiated voice, video and data services
• Full system redundancy and industry leading Nonstop Routing (NSR) and Nonstop Switching (NSS)
• Flexible form factors and network asset portability across the SR portfolio result in optimal CAPEX investment with extended asset longevity and extended
  depreciation cycles
• Sophisticated packet processing capabilities and performance headroom (up to 1 Terabit switching capacity)
• Reduced OPEX and accelerated time-to-market through rapid service provisioning and advanced OAM tools
• Improved service level guarantees through a comprehensive approach to high-availability and QoS levels on a per service, per interface and per user level with a purpose-built hardware and software implementation, leading performance and comprehensive security capabilities
• Common operating system across all service routers and switches for service and operational continuity minimizes approval for use test cycles, eliminates all issues around release and feature backward compatibility and allows for rapid fault isolation

Key features

• Advanced Services: Virtual Private LAN Services (VPLS), Virtual Private Wire Services (VPWS’s), Virtual Private Routed Networks (VPRN’s) based on RFC 4364 and IPv6 based services
• Enable layer 2 and layer 3 services on a single platform with the flexibility of any service over any port over a wide range of interfaces including DS3/E3, Ethernet, SONET/SDH PoS, frame relay and ATM interfaces. Additional interface options include OC-3/STM-1 support on the Any Service Any Port (ASAP) interface card and a combination interface card supporting Gigabit and 10 Gigabit ports
• Multi-service edge: Comprehensive service continuity with FR/ATM/Ethernet pseudowire services (VPWS), Ethernet/FR/ATM service interworking, Ethernet,
  FR and ATM access to VPLS, IP-VPN and Internet services with service aware quality of service (QoS) to maintain stringent service level agreements (SLAs) and ensure a seamless migration to emerging services
• Quality of Service: Service-based quality of service allows for service-based queuing, which enables shaping, policing and marking of different traffic flows on a per service basis. Enhancements include class based forwarding allowing service packets to be directed over specific RSVP LSPs based on their forwarding class and LDP over RSVP-TE allows end to end LDP tunnels to inherit RSVP traffic engineering properties. Hierarchical QoS uses an advanced scheduling mechanism, with multiple levels and instances of queuing, shaping, policing and marking, to prioritize different services over the same connection and combine all services into overall SLA
• High availability: Non-stop services and non-stop routing that provide unparalleled availability and reliability. Non-stop services ensure that VPLS-based services and VPRNs are not affected when there is a CPM switchover on the 7750 SR. With non-stop routing, LDP adjacencies, sessions and the database remain intact if there is a switchover. Other differentiating high availability features include multi-chassis LAG and PW redundancy
• Operations, administration and maintenance: Unmatched service-aware operations, administration and maintenance (OAM) toolkit and mirroring - service assurance capabilities needed to reduce mean-time-to-repair (MTTR) and ensure a predictable end-user experience and fully supported by the Alcatel-Lucent 5620 Service Access Manager which simplifies the provisioning, management and troubleshooting of IP/MPLS networks
• Enhanced troubleshooting tools: In-service software upgrade (ISSU) minimizes downtime between minor release upgrades. Service Assurance Agent (SAA),
  which consists of OAM and debugging tools that allow network operators to collect statistics such as loss, jitter, latency, response time and packet loss.
  Multicast troubleshooting tools includes a full set of troubleshooting tools for multicast that allow network operators to assess the distribution of IP multicast traffic, to trace multicast paths in the network and to calculate performance metrics of the network
