Nokia/Alcatel Lucent 7705 Service Aggregation Router
The Nokia 7705 Service Aggregation Router (SAR) portfolio provides service adaptation, aggregation, and routing over an efficient, feature-rich Ethernet and IP/MPLS/segment routing infrastructure. With interfaces supporting a wide range of access protocols, it is well suited for mobile backhaul, fixed mobile convergence, mission-critical and enterprise applications.
Leveraging the powerful Nokia Service Router Operating System (SR OS) and the Nokia Network Services Platform (NSP), the 7705 SAR delivers industry-leading IP/MPLS/segment routing and Pseudowire capabilities. Designed for scalability, it utilizes programmable processors to accommodate new standards and requirements associated with data plane operation. It is available in compact, power-efficient, indoor and outdoor platforms that support highly available services and applications over flexible network topologies.
Easy legacy TDM migration
The 7705 SAR portfolio offers a comprehensive set of T1/E1, T3/E3, SONET/SDH, serial data, electrical utility teleprotection and analog voice interfaces
along with software features for asymmetrical delay and jitter compensation to ensure that legacy applications perform exactly as they did on TDM networks. Critical traffic is expedited when using either high-speed Ethernet or legacy low-bandwidth links to ensure application performance. Numerous migration features allow operators to gracefully move their applications onto their new IP/MPLS/ segment routing network.
Routing and resiliency
The depth of its IP/MPLS/segment routing protocol implementation and robust OAM capabilities at all levels set the 7705 SAR apart from its competitors. A thorough implementation of the standards provides greater resiliency and more options and flexibility for service definition.
The 7705 SAR’s IP and MPLS scale gives network operators the potential to grow their networks, adding many end users and applications without having to make additional capital investment.
The 7705 SAR provides excellent resiliency to link or equipment failures through redundancy and the ability to quickly reroute traffic. The 7705 SAR delivers network reconvergence in tens of milliseconds using a strong suite of dynamic routing and recovery capabilities. Superior network resiliency reduces network down time and improves operations staff’s productivity, helping to reduce operating costs, improve end-user satisfaction, and allowing service providers to offer higher-value service level agreements (SLAs).
Robust security
The 7705 SAR provides a robust set of security features to maintain network integrity in the face of cyberattacks such as session hijacking, spoofing,
and denial of service attacks. The 7705 SAR firewall is application-aware and mitigates attacks, such as Domain Name System (DNS)/Internet Control Message Protocol (ICMP) replay. It uses application level gateways to ensure extra security for FTP/ T-FTP connections. 7705 SAR hardware-based encryption features, including IPsec, Network Group Encryption and advanced key exchange algorithms, prevent man-in-the-middle attacks. All 7705 SAR security features provide high throughput levels while minimizing latency.
The portfolio is FIPS 140-2 compliant on both the control and data planes. Operators can use the 7705 SAR to safeguard critical infrastructures and address regulatory requirements, such as North American Electric Reliability Corporation (NERC) Critical Infrastructure Protection Version 5 (CIP V5).
Quality of service
Service Router Operating System (SR 0S) software provides superior quality of service (QoS) on the 7705 SAR. The same level of deep buffering and
support for ingress and egress shaping that is available on Nokia’s edge and core routing platforms is also available on the 7705 SAR aggregation platform. Consistency of traffic engineering and shaping across the network provides higher packet routing performance overall with differentiated service treatment. This facilitates the convergence of fixed and mobile traffic for service providers as well as operational and business services traffic for mission-critical network operators. SR OS software allows for advanced service offerings, and delivers efficient network resource usage, customer satisfaction and retention.
Precise timing and synchronization
The 7705 SAR provides microsecond timing and accurate synchronization to support mobile base station requirements and the migration of TDMbased
services onto the packet network. Timing accuracy and performance over packet are enabled with a combination of built-in architectural features, integrated Global Navigation Satellite System (GNSS) receivers, Nokia Bell Labs algorithms, accurate hardware time-stamping, and powerful QoS mechanisms, which minimize the delay and delay variation experienced by synchronization traffic.
Microwave awareness
When used together, the 7705 SAR and Wavence Microwave systems have a number of features that improve routing performance and resiliency over microwave links. A 7705 SAR router and its subtending microwave systems are treated as a single network element with one IP address, simplifying operations and administration. This allows for bandwidth notification, IEEE 1588 synchronization, faster fault detection, and rerouting with various microwave redundancy architectures supported. The microwave systems can be powered from the 7705 SAR system reducing space and cost.
Field longevity
The Nokia 7705 SAR portfolio is packaged in a wide range of form factors to accommodate the density and types of services required at any location. It
provides both indoor and outdoor mounting solutions combined with extended temperature range and power-over-Ethernet (PoE) options. Fanless and conformal-coated variants allow the 7705 SAR to be used in harsh environmental conditions. 7705 SAR platforms are mechanically hardened with a robust electromagnetic compatibility (EMC) design. Several platforms comply with the IEEE 1613, IEC 61850-3 and EN 50121-4 standards for power substations and railway environments.
