5G-ICN: Delivering ICN Services over 5G Using Network Slicing

The challenging requirements of 5G, from both the applications and architecture perspectives, motivate the need to explore the feasibility of delivering services over new network architectures. As 5G proposes application-centric network slicing, which enables the use of new data planes realizable over a programmable compute, storage, and transport infrastructure, we consider information- centric networking as a candidate network architecture to realize 5G objectives. This can coexist with end-to-end IP services that are offered today. To this effect, we first propose a 5G-ICN architecture and compare its benefits (i.e., innovative services offered by leveraging ICN features) to current 3GPP-based mobile architectures. We then introduce a general application-driven framework that emphasizes the flexibility afforded by network functions virtualization and software defined networking over which 5G-ICN can be realized. We specifically focus on the issue of how mobility as a service (MaaS) can be realized as a 5G-ICN slice, and give an in-depth overview on resource provisioning and inter-dependencies and coordination among functional 5G-ICN slices to meet the MaaS objectives. The article tries to show the flexibility of delivering services over ICN where virtualization of control and data plane can be used by applications to meet complex service logic execution while creating value to its end users.

VR Video Conferencing over Named Data Networks

We propose a VR video conferencing system over named data networks (NDN). The system is designed to support real-time, multi-party streaming and playback of 360 degree video on a web player. A centralized architecture is used, with a signaling server to coordinate multiple participants. To ensure real-time requirement, a protocol featuring prefetching is used for producer-consumer communication. Along with the native support of multicast in NDN, this design is expected to better support large amount of data streaming between multiple users. As a proof of concept, a protoype of the system is implemented with one-way real-time 360 video streaming. Experiments show that seamless streaming and interactive playback of 360 video can be achieved with low latency. Therefore, the proposed system has the potential to provide immersive VR experience for real-time multi-party video conferencing.

Demo abstract: CDMA-based IoT services with shared band operation of LTE in 5G

With the vision of deployment of massive Internet-of-Things (IoTs) in 5G network, existing 4G network and protocols are inefficient to handle sporadic IoT traffic with requirements of low-latency, low control overhead and low power. To suffice these requirements, we propose a design of a PHY/MAC layer using Software Defined Radios (SDRs) that is backward compatible with existing OFDM based LTE protocols and supports CDMA based transmissions for low power IoT devices as well. This demo shows our implemented system based on that design and the viability of the proposal under different network scenarios.

ICN Based Scalable Audio-Video Conferencing on Virtualized Service Edge Router (VSER) Platform

This paper proposes an audio/video conferencing architecture based on the VSER platform. The proposed solution follows a hybrid approach, where consumers are initialized to current producers media state through a media-dependent notification framework provided by the VSER; whereas the data exchange leverages ICN features, resulting in bandwidth efficiency. The hybrid design provides better scalability and reliability when compared to the ICN based P2P conferencing systems.

This demo shows an implementation of 360/virtual reality video conferencing system implemented over NDN, including producing content, formatting into NDN format, transmitting over NDN network, managing the flow of interest/content requests, and displaying in a web browser so as to show 360 degree rotation and zoom in/out features.

Realization of CDMA-based IoT Services with Shared Band Operation of LTE in 5G

5G network is geared towards massive deployment of Internet-of-Things (IoTs) with requirements of low end-to-end latency, low control overhead and low power transmissions. Current 4G network is optimized for large bandwidth applications and inefficient to handle short sporadic IoT messages. This paper focuses on low power underlay CDMA access for IoT devices considering event-driven and latency sensitive traffic profile, thus will significantly reduce the access time. We propose a PHY/MAC layer design for CDMA based communication for IoT devices. We evaluate coexisting operation of CDMA based IoT network in presence of the exiting LTE network. Our proposed protocol will integrate IoT traffic with legacy system by minimal modification at the edge network, essentially eNodeB. We show that the underlay CDMA IoT network meets IoT data traffic requirements with minimal degradation (~ 3%) to the LTE throughput. We also implement the proposed design using Software Defined Radios and show the viability of the proposal under different network scenarios.

A Bloom Filter approach for scalable CCN-based discovery of missing physical objects

As the number of devices which could be potentially connected to the Internet scales up, as the amount of traffic generated by these devices will explode, it is necessary to reconsider the underlying protocols which will support the Internet of Things. The request/response semantics of CCN are well suited to the retrieving data from a set of sensors and we consider here the deployment of CCN to retrieve missing objects in a distributed environment. We developed a demonstrator of it as a proof-of-concept. We then consider the scalability of such system and demonstrate how the combination of a Bloom Filter mechanism in addition to the CCN primitives allow for a very scalable deployment of an object retrieval function.

Leveraging ICN for Secure Content Distribution in IP Networks

Recent studies shows that by the end of 2016 more than 60% of Internet traffic would be running on HTTPS. In presence of secure tunnels such as HTTPS, transparent caching solutions become in vain, as the application payload is encrypted by lower level security protocols. This paper addresses this issue and provides an alternate approach, for contents caching without compromising their security. There are three parts to our proposal. First, we propose two new IP layer primitives that allow routers to differentiate between IP and ICN flows. Second, we introduce DCAR (Dual-mode Content Aware Router), which is a traditional IP router enabled to understand the proposed IP primitives. Third, design of DISCS (DCAR based Information centric Secure Content Sharing) framework is proposed that leverages DCAR to allow content object caching along with security services that are comparable to HTTPS. Finally we share details on realizing such system.
