Towards Software Defined ICN based Edge Cloud Services Version: V1.0( ) IEEE, CloudNet, 2013 Ravi Ravindran, Xuan Liu, Asit Chakraborti, Xinwen Zhang, Guo-Qiang Wang (Huawei Research Lab, Santa Clara)

2 ICN Motivation About a ~2 years back, ICN-RG (IRTF Working Group) was formed, which made the term ICN official. – Umbrella of many protocols CCN/NDN, MobilityFirst, NetInf, PSIRP etc. ICN aims at making information as the waist rather than connectivity as in IP. ICN is a unified platform which addresses several IP issues with Multicast, Multi-homing, Security, and Mobility. But why Deploy it ? – New Things, Applications/Services – Connectivity: Adhoc + Infrastructure interactions, Multi-Cloud – Do things in an efficient and scalable manner than existing applications. This paper focuses on a way Operators can gain from ICN.

3 Industry Trends and Opportunities De-coupling increases flexibility, encourages innovation and faster evolution. Services/Applications will drive new technologies, same is the case for ICN too. The SDN/NFV allows ICN introduction atleast in an experimental manner. SDN Control Plane Forwarding Plane NFV Software (Network Functions) Hardware ICN Applications Transport Services/Applications Long Term (Adhoc/ Infrastru cture)

Service Virtualization, applications are tightly bound to service locators. SDN drives service-centric network programmability. Today realized as overlaid service engineering or at the edge (Data centers) ICN inter-connects Consumers with Services at the information level, in a receiver-centric model. NFV enabled service virtualization, with SDNs service-centric network programmability, and Information-Centric Service Connectivity can realize rich services. Creates a win-win model for both Operators and ASPs. NFV: Service Virtualization ICN ConsumersServices SDN : Service- centric Network Programmability

12 Scenario -1: Device Context Adaptation In this example user changes the device from the smart phone to a smart TV. The device simulataneosly signals the action to the service gateway and the peer device, the gateways forwards the control message to the Video Service Controller Application. The controller orchestrates a new service composing the fetching of video and real-time transcoding service. Here the service is virtualized among device applications.

For specific usage details, refer to the Typesetting Standard. Varying Content Generation Rate and Network Conditions Here the Link capacity is set to 0.1Gpbs. The content rate causes proportional increase in data traffic, hence the convergence time increases. Page 23 The convergence time improves as long as the capacity of the network link is planned correctly.

Can Leverage all ICN features : Name based Routing, Multicasting, Security, Mobility Handling. Combined with NFV and SDN allows to achieve the goal of true Service Centric Networking. Platform suitable for ICN applications: Conferencing, IoT/M2M, Video Multicasting. Conferencing can be enabled as a VNF over the platform. Showed through simulation analysis the scalability of the conferencing framework. We are prototyping this platform, hope to share our experience on this in the future..! Page 25
