1.5 Realizing ICN as a Slice for Mobile Data Distribution
Asit Chakraborti, Aytac Azgin, Huawei

The demo highlighted: 1) Dynamics ICN slice management; 2) ICN service orchestration; 3) Dynamic
mobility over a slice, and as a service; 4) Seamless mobility over heterogeneous access links (LTE,
Ethernet, Wi-Fi); 4) Real-time A/V conferencing application. Network slicing is proposed in a 5G
system to cater to the needs of diverse heterogeneous applications. From the core network
architecture perspective, delivering services over Internet protocol (IP) also carries forward its
shortcomings with respect to handling naming, security, mobility, multi-homing and multicasting.
Also, the IP model does not allow easy integration of computing or storage into the network
infrastructure, which can address the latency and bandwidth challenges offered by 5G applications.
All the above motivates leveraging network slicing to introduce new architectures, such as ICN, that
have native support for features that cannot be deployed or which have little deployment or support
over an IP infrastructure. Considering a generic networks slicing infrastructure that can offer services
over both IP and ICN, this proof-of-concept (PoC) is developed to demonstrate the realization of ICN
as a slice, where the slice is dedicated to a single service or one that multiplexes multiple ICN services.
This demo showed the feasibility of using standard orchestration software such as Docker and ONOS
with ICN extensions and adaptation to realize ICN as a slice over a common pool of x-86 resources.
In particular, PoC demonstrated: 1) Dynamic creation and co-existence of multiple ICN slices to offer
real-time audio/video conferencing; 2) Application driven ICN service orchestration and
management using Docker and ONOS; 3) Dynamic enablement of mobility-as-a-service over a slice;
4) Seamless producer mobility over heterogeneous access, which in this case included, LTE, Wi-Fi and
Ethernet.

Presentation
This demonstration represented a technique that enabled the live migration of a 5G service between
different technological domains, such as a NAT running as an SDN application in the first domain, or
running as a VM in a data centre in the second case. This was achieved by distilling the state of each
application by means of a technology-independent data-model, whose run-time data was
transferred from the first instance to the second. This technique (i) guarantees a faster migration
process because of the smaller information footprint that has to be transferred; (ii) offers more
flexibility to execute services in a telco infrastructure; (iii) can strengthen the robustness of the
infrastructure, e.g. by keeping in “hot standby” multiple copies of the same service running in
different domains; (iv) and provides a way to upgrade a service, e.g. with a new, feature-richer
version, without any downtime of the service itself.
