As operators look for new ways to bring network functions virtualization (NFV) to their networks, Alcatel-Lucent now is virtualizing IP / MPLS service routing. This week the company launched its Virtualized Service Router (VSR), the industry’s first virtualized IP/Multiprotocol Label Switching MPLS router. Based on Alcatel-Lucent’s Service Router Operating System (SR OS), the VSR is designed to help IP networks and services scale flexibly as demand grows.
A new application note from Alcatel-Lucent looks at how the VSR was architected for NFV and outlines deployment options, performance in the control plane, and key implementation innovations.
Architected for x86 server environments, the Alcatel-Lucent VSR provides a homogenized physical infrastructure and NFV management and orchestration to help enable rapid service innovation, elastic scalability, and lower operating costs.
The featured app note focuses most closely on the VSR Route Reflector (VSR-RR), which is functionally and operationally equivalent to a 7750 SR hardware-based BGP RR. BGP RR is an ideal function for virtualization because it is mainly a control-plane function with minimal traffic in the data plane. RR operation also is memory and compute-intensive and well-suited to run on x86-based server platforms.
The app note, “Alcatel-Lucent Virtualized Service Router – Route Reflector: Creating a New Benchmark for Performance and Stability,” also highlights performance tests for the VSR-RR against an alternate commercially available vRR solution not optimized for x86-based deployments. According to Alcatel-Lucent, the VSR achieved 8x faster performance in the control plane over alternate vRR implementations.
Architected to get the best performance, resilience and reliability on x86 compute platforms, the VSR-RR supports innovations such as parallel SMP and a 64-bit OS.
