  • SD-WAN (software-defined WAN)

    Software-defined WAN (SD-WAN) is a technology to distribute network traffic across wide area networks (WAN) that uses software-defined networking (SDN) concepts to automatically determine the most effective way to route traffic to and from branch offices and data center sites.

  • east-west traffic

    East-west traffic, in a networking context, is the transfer of data packets from server to server within a data center. The label east-west comes from network diagram drawings that usually depict local area network (LAN) traffic horizontally.

  • ONOS (Open Network Operating System)

    ONOS (Open Network Operating System) is an operating system (OS) designed for network service providers to help build carrier-grade software-defined networks architected for high scalability, availability and performance
