Presenter Introduction

• Completed bachelors from CSE, Dhaka University (2nd Position) – 2006

• Received Erasmus Mundus scholarship from European Commission, and completed Masters from KTH, Sweden, and HUT, Finland with CGPA 5.0 – 2009

• Working as a System Architect at Nokia Siemens Networks headquarters in Finland

• In parallel continuing Ph.D. on future Internet

Content based Internet

Traffic Pattern

• Traffic pattern is changing all over the world

• Client-Server based communication is obsolete

• People wants to access content, irrespective of where it’s originating from

▫ 55% of the Internet traffic will be video by 2014

▫ 65% if all mobile traffic will be video by 2014

• Communication technology needs to adapt to this change

4

Current naming and its problems

• Current names (URI) are basically locators

▫ Resolving URI to IP address of the server

▫ Object movement breaks locator address

• Security model identifies endpoint

▫ Object is not inherently secured

▫ Can be modified in the middle

5

Paradigm Shift

• From end-to-end:

• To information centric:

6

Information Centric Networking

• Receiver driven

▫ Receiver expresses interest

▫ Interest is routed to any source

• In network caching

▫ Content cached in the network efficiently

▫ Content delivered from cache whenever possible

• No need (or change) for services like “Google”

7

Content naming

• Content name should depend on the content

• Should ensure same content has same name

▫ Content fingerprinting

▫ Crypto-signature

• Huge namespace is a problem

• Routing via content name instead of IP address

8

Current research efforts*

• Name resolution and routing

• Intermittent connectivity

• Flow control

• Security

• Load balancing

• Caching

* From CCNxCon 2012 at Nice, France

My research area

• Efficient Caching in ICN

• INFOCOM 2013 paper1

▫ Efficient caching and object distribution

▫ Flattening namespace and divide responsibility

▫ AS-level granularity

▫ Use of Pathlet2-like routing protocol

▫ Better cache efficiency provides better hit ratio, reduces server load, etc.

Conclusion

• Information centric networking is a very hot topic right now

• Multiple European and American projects ongoing

▫ PSIRP

▫ 4WARD

▫ CCNx

▫ COMET

• Many research questions yet to be answered
