Computer Science—the theory, representation, processing, communication and use of information—is fundamentally transforming every aspect of human endeavor. The Department of Computer Science at Iowa State University advances computational and information sciences through; 1. educational and research programs within and beyond the university; 2. active engagement to help define national and international research, and 3. educational agendas, and sustained commitment to graduating leaders for academia, industry and government.

History
The Computer Science Department was officially established in 1969, with Robert Stewart serving as the founding Department Chair. Faculty were composed of joint appointments with Mathematics, Statistics, and Electrical Engineering. In 1969, the building which now houses the Computer Science department, then simply called the Computer Science building, was completed. Later it was named Atanasoff Hall. Throughout the 1980s to present, the department expanded and developed its teaching and research agendas to cover many areas of computing.

Abstract

The main usage of Internet today is content distribution and retrieval. In today’s Internet, connections and data exchanging can only happen between hosts, which is also called host centric end-to-end communication. As the network users and demand of contents grows quickly, current network paradigm is getting more and more complicated and can barely meet the needs in the future. Recently, the architecture of information/content centric networking (ICN) has been proposed and is expected to replace the current communication model. As an in-network caching system, the cache management scheme is a key factor of ICN. To improve the performance of this architecture, a lot of effort has been put by many researchers into this area. In this paper, a new strategy about content caching and routing is introduced. And the results of this new scheme show that this strategy leads to a good performance, i.e., the new scheme can reach less hops, when comparing with regular LRU cache strategy. And less hops means the requested object can be found in nearer routers, the network traffic, hence, is reduced.
