ICN @ Huawei
• Since 2009; 7 people group in Santa Clara Innovation Center; interns +
university collaborations
• Interest in potentially disruptive routing technologies
Topics:
• Security
• Naming
• Mobility
• IoT/M2M
• Content & Cache Management
– How to locate content/distribute state information/scalability benefits
• Architecture
– How to integrate storage as network elements; content as a network primitive.

Information Centric Networks:
Built upon the need to separate the what from the where
Most communications are exchange of data which does not require to set-up a
host-to-host path
Telephony: host-to-host, circuit switched
IP Internet: end-to-end, packet switched
ICN: host-to-content
Future Networks will be able to store/cache/serve content from a diversity of
locations
Storage associated with routers, in the network, as opposed to
restricted to some edge (end users edge or data center edge)

The Architectural Case for Information Dispersion
through Network Coding
By disconnecting the what from the where, ICN architectures multiply the potential
locations for data and retrieval opportunities
Being agnostic from where the data is coming from mean it potentially comes for
multiple locations
How to synchronize multiple independent data streams?
How to share information on distributed states?
In P2P, NC is proven to help to gather data from multiple peers
Can these principles be inserted into the network architecture?

NC3N: Network Coded CCN
Gain also when the consumer is sending Interests over multiple interface
Additive gain when interfaces are asynchronous, say 3G and WiFi
Bandwidth is saved as no duplicate packets over the network
Each packet a new degree of freedom
Delay is reduced as second interest will be answered directly from the Cache in the
middle instead of a repository at the top.
Proposal to integrate network coding information in CCN to allow for network coded
packets (specific Interest format)
