Dr. Ralph Droms (Cisco Systems, Inc.)
The Internet Protocols and ICN: Replacing Devices with Data in the Internet

May 26, 2016 - 4:00pm



Abstract

Communication protocols are the methods used for the exchange of data among devices interconnected by a telecommunication network. The word protocol comes from the Greek protocollon, meaning a leaf of paper glued to a manuscript volume that describes the contents. A communication protocol is a set of rules that describe the contents and meaning of the contents of messages sent between devices. Devices connected to the Internet use a collection of protocols called the Internet protocols. These protocols work from some basic assumptions about the roles of hosts and routers, communication between devices and addressing, to name a few, that shape the protocols and the applications that use the Internet for communication. In this talk, we will look at some of these basic assumptions and their effects on how the Internet works. In the past few years, an alternative networking technology called Information Centric Networking, or ICN, has been developed based on a radically different communication paradigm. ICN replaces the end-to-end communication between devices with fixed addresses on which the Internet protocols are based with data identified by names as the primary entities in the network. We will introduce the ICN communication paradigm and semantics, and explore some specific outstanding questions regarding the use and deployment of ICN. There are a variety of characteristics of ICN that may make ICN a better choice than the Internet Protocol in certain deployment scenarios. We will look into several such potential use cases, including mobility, distribution of very larges datasets, the Internet of Things and video delivery. Finally, we'll discuss the pragmatic problems with displacing a widely deployed system like the Internet Protocols.



Short bio

Dr. Ralph Droms is a Distinguished Engineer in the CTAO organization at Cisco. He is currently involved in research into the use of Information Centric Networking (ICN) in sensor networks and development of highly scalable DNS Service Discovery. Ralph is a member of the Internet Architecture Board (IAB) and is also active in the IETF, where he organized and is now co-chair of the "Extensions for Scalable DNS Service Discovery" (dnssd) working group, as well as technical advisor for the "IPv6 over Networks of Resource-constrained Nodes" (6lo) working group. He was an Internet Area Director in the IETF from 2009 to 2013. Prior to his appointment as Area Director, he organized the "Dynamic Host Configuration" (dhc) Working Group in 1989 and chaired the WG until 2009. He is responsible for many of the DHCP specifications and has authored more than 20 RFCs as well as "The DHCP Handbook". In addition to his work in the IETF, he was a contributor to the ZigBee Alliance "ZigBee over IP" specification, editor for the IPv6 functions in the CableLabs DOCSIS 3.0 specification and has contributed to other standards bodies. Before he came to Cisco, Dr. Droms was on the faculty at Bucknell and Penn State universities. He has also been on the research staff at both IBM and Burroughs (Unisys).
