Why Virtual CPE for Enterprises?Revenue growth plus cost savings for service providers7 2016 Wind River. All Rights Reserved.
Revenue Growth from Agile, On-Demand Services Managed network services for enterprises isalready a lucrative market for service providers 135B worldwide in 2016 MPLS, Ethernet, VPN, WAN Optimization, Security vCPE presents significant growth opportunity forfirst movers Scalable, automated deployment of existing and newservices Self-provisioning by customers accelerates adoption cycle 5% annual revenue growth per site8 2016 Wind River.

40-50% Cost Savings from Migration to vCPE Replace expensive, dedicated physicalappliances with standard servers 42% savings in equipment CAPEX and OPEX Remove inefficiencies in manual equipmentinstallation and service provisioning 72% savings in “Order to Cash” (O2C) Eliminate most truck rolls and accelerateremote resolution of failures 61% reduction in “Trouble to Resolve” (T2R) costs10 2016 Wind River.

SDN and NFV are Key Enablers for Cost Savings Equipment CAPEX and OPEX savings driven bylow-cost standard servers Efficient resource utilization thanks to virtualization No stranded assets Aggressive VNF pricing driven by competition SDN and NFV drive efficiency in Order-to-Cash Accelerated, self-service provisioning of new services CPE virtualization minimizes support costs Customer site repairs mostly eliminated11 2016 Wind River.

Four Challenges to Cost-Effective Business CPE Service reliability Service agility Virtualization overhead Server footprint13 2016 Wind River. All Rights Reserved.
vBCPE Challenge #1: Service Reliability Enterprise customers expect high reliability frommanaged services Whether provided by traditional appliances or delivered byvirtual CPE software Typical requirement is five-nines uptime (99.999%) Service downtime impacts service provider revenues Service Level Agreement (SLA) penalties plus operational expenses plus customer churnVirtualized CPE services need to maintain reliability of traditional physical implementations14 2016 Wind River.

vBCPE Challenge #2: Service AgilityExample OpenStack has no primitives to reconnectthe firewall interface from the router to theWAN acceleratorBefore:RouterFirewall Only options are: Either delete the firewall interface and reconnect,which may lead to ambiguity because firewall rulestied to specific virtual NICAfter:RouterWANAcceleratorFirewall Or provision new service chain from scratch whichcauses outage of at least five minutesNeed a solution for reconfiguring service chains with minimal service downtime18 2016 Wind River.

vBCPE Challenge #3: Virtualization OverheadVNFs Multiple elements contribute to bottom-linecost-per-user Needs to be favorable vs. physical appliancesFixed-FunctionAppliances per userVirtualization Platform Goal is lower costs plus increased revenuesStandard Servers Virtualization overhead is a major factor per userCAPEX, OPEX, Order-to-Cash,Trouble-to-Resolve etc. Off-the-shelf virtual switches have very lowperformance vs. physical switches Limits VNF performance Causes inefficient resource utilizationNeed to ensure that virtualization overhead is minimized20 2016 Wind River.

High Performance vSwitching Drives OPEX Savings Example: Accelerated vSwitch integrated inTitanium Server 40x performance of Open vSwitch (OVS) Fully compatible with Open vSwitch: standard APIs Increased switching performance greater VMdensity Fewer cores required to run vSwitch More cores available for VMsGreater VM density reduced OPEX More users per serverVirtualization overhead is minimized21 2016 Wind River. All Rights Reserved.Example use case: virtualized media gatewaySystem configuration: 28-core platform (dual socket) with one VM per core Bandwidth required: 3.5 Gbps per core (6.8 Mpps per core)Most efficient implementation using Open vSwitch 23 cores required for switching, 1 core running VM, 4 unusedMost efficient implementation using Titanium Server 10 cores required for switching, 17 cores running VMs, 1 unused17x improvement in VM density
vBCPE Challenge #4: Server FootprintEspecially critical issue for customer premise deployments Need to deploy vBCPE on low-cost servers Customers won’t pay more for servers than for physical appliances Solution price has to include VNFs and virtualization platformService Provider Data Center Must ensure service reliability required by enterprises Minimum two servers for redundancy on hardware failures Server utilization must be optimized Only compute nodes run the services that generate revenueService ProviderPoint-of-Presence (PoP) Control and storage nodes represent overhead costsorCentral Office (CO)22 2016 Wind River.
