Virtualized service router

Deliver virtualized network functions (VNFs) for x86 server environments

The Nokia Virtualized Service Router (VSR) is a highly flexible virtualized IP edge router designed and optimized for telco cloud environments. It enables rapid service innovation while lowering operating costs. With the VSR, service providers can extend service reach, open new markets, and accelerate time to market.

The VSR supports a broad and rich set of virtualized IP edge applications – virtualized network functions (VNFs) to support mobile, business, and residential services.

Based on the Service Routing Operating System (SR OS), the VSR delivers high performance and elastic scalability for x86 server environments.

The VSR supports the highest levels of reliability and resiliency. It also offers flexible management options – from working with open frameworks to delivering OpenStack®-integrated VNF management and element management capabilities with our 5620 Service Aware Manager (SAM).
