Carrier-grade routing delivered through software.
Modern networks today demand scalability, adaptability, and fast failure convergence irrespective of on-premises, cloud or the edge. To meet these demands, VOS™ and VOS with Titan deliver high-performance, application aware intelligent routing to guarantee performance at scale.
With Versa, you can get carrier-grade routing support through VOS and VOS with Titan that optimizes both common and advanced routing protocols which are crucial for WAN and LAN network agility. These include Static, OSPF, BGP, MP-BGP (MPLS based L3VPN, MPLS based EVPN, VXLAN based EVPN), RIP, IGMP, PIM, VRRP, PBR (policy-based routing).
Versa support Bi-Directional-Forwarding (BFD) that can be used with routing protocols such as BGP to monitor control plane health checks and provide sub-second failure convergence.
VOS supports IPv6 on both the LAN and WAN interfaces and all permutations of dual stack such as:
- IPv4 LAN over IPv6 WAN transport
- IPv6 LAN over IPv4 WAN transport
- IPv6 LAN over IPv6 WAN transport
Additionally, VOS natively supports Virtual Routing Forwarding (VRF), MPLS over GRE, and MPLS over IPsec to interoperate directly with the Service Provider Edge. With all of these capabilities available through an easy software architecture, Versa Networks offers the most robust and scalable routing solution for the modern Enterprise.
Delivering dynamic network intelligence to cloud.
One of the biggest networking challenges in cloud is very limited support for multicast, broadcast and dynamic routing. Such limitations adversely affect network resiliency in cloud. VOS overcomes these networking challenges in the cloud by using purpose built, cloud-native routing protocols.
These protocols can track the state of system objects like routes, interfaces and monitors and interact with the cloud environment to re-route around failures. VOS leverages this technology in cloud to deliver fast failure convergence, with near zero downtimes.
Routing that understands application context.
VOS and VOS with Titan auto-recognizes over 3600+ applications. VOS and VOS with Titan continuously monitor links, transport-paths and application performance (bandwidth, latency, jitter, error rate, packet loss, MOS, MTU etc.). VOS and VOS with Titan leverages this information for application-based link selection, intelligent traffic engineering, and smart re-routing. The solution also provides application-aware traffic steering and can consider time of day, link type (MPLS vs Internet), application requirements (bandwidth, delay, jitter, error rate) and link performance.
The solution can measure the MOS score for individual sessions of 190+ codecs. This MOS score can be used to make traffic routing decisions. Paths with better MOS score are chosen, ensuring users always experience the best voice, video and audio quality. VOS also supports first packet identification of SaaS applications such as Office365, ensuring that optimal path selection policies are effective from the first packet itself.
