Nokia 7250 IXR 10
Interconnect Routers

Nokia IXR-10 routers enable high-scale interconnectivity in data centers and across WANs and aggregation networks in service provider, enterprise and webscale environments.

The IXR-10 interconnect router complements IP edge and core router platforms to deliver enhanced, cost-effective IP network architectures. The 7250 IXR delivers a comprehensive set of IP/MPLS, synchronization and quality of service (QoS) capabilities. Flexible traffic management includes big buffering, per-port queuing, shaping and policing.

Nokia 7250 IXR Product Family

The Nokia 7250 Interconnect Router (IXR) family addresses evolving demands driven by the cloud, 5G and the Internet of Things. The IXR-10, IXR-6 and IXR-s routers enable high-scale interconnectivity in data centers and across WANs and aggregation networks in service provider, enterprise and webscale environments.

The 7250 IXR-10 is optimized for high-density aggregation, and is equipped with high performance 100GE (Gigabit Ethernet), 50GE2, 40GE, 25GE, 10GE and GE interfaces to scale networks to meet evolving traffic demands.

Features & Benefits

    Differentiated service support

  • Per-service, hierarchical queuing features support differentiated QoS, which is ideal for any-G aggregation and fixed-mobile network convergence. These features also help industrial enterprises attain IT/OT (informational technology/operational technology) convergence by simultaneously carrying both their business and operational traffic.

    • High availability

  • The 7250 IXR sets the benchmark for high availability. The 7250 IXR-10 and IXR-6 systems support a full suite of 1+1 control, 5+1 fabric, and redundant fan and power configurations. In addition to full hardware redundancy, the robust Nokia Service Router Operating System (SR OS) supports numerous features to maximize network stability, ensuring that IP/MPLS protocols and services run without interruption. These features include innovative nonstop routing, nonstop services and stateful failover.

    • Automation

  • To simplify and automate network operations, the 7250 IXR enables model-driven network management features through the Nokia SR OS and is managed by the Nokia Network Services Platform (NSP). The Nokia NSP offers a rich set of service management features that automate new service delivery and reduce operating cost. Standards-based software-defined networking (SDN) interfaces enable best-path computation to be offloaded to path computation elements (PCEs) such as the Nokia NSP. The 7250 IXR operates as a path computation client (PCC), collecting and reporting perlink and per-service delay, jitter and loss metrics as well as port utilization levels, for efficient path computation.
