The session covers how Network Function Virtualization and cloud based management is impacting the branch environment. The session covers the basics of NFV and then drill down into how network functions virtualization is changing the branch landscape and some of the special challenges involved in building highly resilient virtualized branch infrastructure and its linkage back to virtualization in the data centre. The session ends with a demonstration of Cisco’s vbranch solution.

Impact of Network Functions Virtualization in the branch
• Reduce service capability in branch
• Services run virtualized in the data center
• Works well with network based VPN solution
• Service capability remains in the branch
• Services run virtualized in branch
• Works well with overlay based VPNs

vBranch templates types
• Service only - I want a VPN, firewall and enhanced web filtering
vBranch orchestrator decides VNFs, connectivity and their day 1 / 2 configuration
• VNF only – I want a CSR router, an ASAv and a WSAv
vBranch orchestrator logically connects VNFs, spin them up and load day 0 configuration
• Mixture – I want a VPN and firewall and a WSAv
