Mission of OPNFV

• Multivendor, interoperable NFV solutions

• Consistency, performance and interoperability among NFVIs

• Unlimited potential of new use cases, services and business


OPNFV is a carrier-grade, integrated, open

source platform to accelerate the introduction of

new NFV products and services

Objective of PoC Zone

• To highlight industry projects and end-user use cases featuring real-life applications of the platform

• To promote open innovation on top of the platform through collective and collaborative efforts in open source environment

• To demonstrate a vision of accelerated time-to-market for new services enabled by the platform

• To showcase the feasibility of improved business agility resulting from the platform

AT&T – BGPVPN-based Service Chaining

• Goal is to demonstrate

– End-to-end L3VPN (BGPVPN) connectivity between two data centers is set up by SDN Controller

– KVM and NFVi running within each data center are hosted and managed using OpenStack

– An OpenStack compliant orchestrator is used to orchestrate and configure SDN Controller components and VNFM

– Intra-VM/container service chaining for multiple VNFs

Cable Labs – Virtualized Business CPE• Goal – investigate and identify means to

facilitate fulfillment of Ethernet/connectivity services using virtualized technologies

• Demo – EPL Provisioning using ODL

• PoC implements prototype APIs and ODL plug-ins

– Simple web UI emulating a user portal initiates EPL service

– APIs call ODL to configure instances of OVS to behave like UNIs

– APIs call ODL to configure GRE tunnel between OVS to emulate EVC

– When tunnel is created, traffic passes client laptops

– Tunnel can be terminated from web UI


Cable Labs – Virtual Home Network Parental Control

• Parental Control using a Docker container on a Raspberry-Pi

– At a portal, a subscriber visually applies the Parental Control policy to a child’s device.

– A Rest call pulls a Docker Container from the Docker or Cable operator’s cloud to an R-Pi.

– The container self-installs, routing is applied and now websites are filtered on the child’s device.

– The subscriber can add to the blacklist using the portal to further customize that list.


CENGN – SDN Solutions Showcase

Multi-Site Multi-Domain Data Center Capacity Management


• SMB:

• Member:

• Partners:

• Use-case:

– Bandwidth on Demand for Inter-DC applications such as Workload migration

with the use of SDN at optical and switching layers.

• Project Summary:

– Showcase the ability of a network under SDN to control (based on

OpenDaylight (ODL)) elephant flows, based on an application trigger

– Features a scenario that throttles low priority traffic to a minimum bandwidth in

order to accommodate the transfer of a large flow of data between the two data

centres

– This will be demonstrated using live link in the CANARIE network between

Ottawa and Montreal CANARIE POP

Orange-sponsored PoCGlobal Software-Defined WAN based on NanoService vCPE

• Participants

– Orange – ClearPath Networks– Intel

• PoC Objective

– Achieve significant CAPEX & OPEX cost reduction for global managed secure networking solutions• CSP Challenges

– De-risk launch of new products & propositions

– Avoid time & cost of on-site installation engineers

– Enable continuous product refresh & extension without high upfront investment costs

– Utilize both premise-based VNFs with cloud-based VNFs• PoC Approach

– Save CAPEX & OPEX by running MANO & VNFs in OPNFV-compliant cloud

– Save CAPEX with VNFs in nano-sized (<10 MB) virtual containers in a VM or a COTS x86

– Save OPEX by dynamically refreshing/extending proposition via broad VNF catalogue
