Troubleshooting Wireless Networks

• virtual network functions (VNF)

  Virtual network functions (VNFs) are virtualized tasks formerly carried out by proprietary, dedicated hardware. VNFs move individual network functions out of dedicated hardware devices into software that runs on commodity hardware. Continue Reading

• network functions virtualization (NFV)

  Network functions virtualization (NFV) is an initiative to virtualize network services traditionally run on proprietary, dedicated hardware. Continue Reading

• edge router

  An edge router is a specialized router located at a network boundary that enables a campus network to connect to external networks. Continue Reading

• hybrid WAN

  A hybrid WAN is a wide area network that sends traffic over two or more connection types. Hybrid WANs permit dynamic traffic engineering across both private and public domains, using a variety of connectivity options to make the best use of network ... Continue Reading
