Download Product Brief

VirNOS provides a virtual networking solution for Network Functions Virtualization to help network operators reduce their CapEx and OpEx costs, accelerate time-to-market for new services, increase agility, and deploy new network services faster. VirNOS supports many use cases such as distributed or cloud based vCPE, vPE for carriers’ network, vRouter for data center network, and OpenFlow support for SDN deployments, etc.

Based on the widely-deployed and time-tested ZebOS® network platform, VirNOS is designed to meet the requirements for today’s networks by supporting many networking functionalities such as MPLS L3VPN, MPLS L2VPN, IPv4, IPv6, OSPF, ISIS, BGP, LDP, RSVP-TE, QoS, OpenFlow and network security.

With VirNOS, customers have a high performance software solution to leverage standard COTS servers with generic CPUs. Network operators can build and deploy diverse services at less cost by using standards-based hardware and achieve the disaggregated networking model. They can integrate VirNOS into their software offering to add services and features more quickly.

Overview

Network operators are facing the increasing challenge of integrating and maintaining a variety of proprietary hardware, compounded with increased energy costs, capital investment and space requirements. Carriers are expected to deliver new revenue-generating services in rapidly evolving markets with reduced time to bring the service to market. At the same time, IT organizations are being asked to deliver new services and functions at increasing speeds and decreasing CapEx and OpEx costs, with increased agility and cost effectiveness.

Many core networking services including switching, routing, load balancing and VPN can now be performed by software either running directly on x86-64 servers or running as virtual machines, therefore more networking functions are being migrated to standard IT, high-volume server environments. Through Network Functions Virtualization (NFV), network services are virtualized via software, giving network operators a different approach to designing, deploying and managing networking services.

NFV replaces dedicated network hardware with virtualization software running on commodity servers. NFV decouples network functions from proprietary hardware appliances and implements the network functions through software. NFV utilizes standard IT virtualization technologies that run on a range of industry standard, high-volume service, switch and storage hardware to virtualize network functions.

Addressing Network Challenges

With VirNOS™, IP Infusion provides carriers, service providers, enterprises and network equipment manufacturers a complete NFV-based software package which customers can run, as-is, on top of the standard server platform. IP Infusion customers can integrate VirNOS into their software offering and thereby be able to add services and features more quickly.

VirNOS addresses today’s networking challenges with:
