Linxu based kernel level content switch or application level content switch design: we have developed linux based content switches lcs and lacs for routing packets based on ip/port/ssl session id/url/xml content of the incoming packets and a set of switching rules. Related research topics are: conflict detection of contet switching rules can be applied to network policies. It was found that ssl processing is the bottleneck in lacs but it requires additional support before the https requests can be redirected to another content switch. Fast string matching/extraction techniques: both in searching engine and http/xml content extraction we have observed needs for matching specific string pattern and then extracting part of the string pattern, or string with position relative to the string pattern.

Related research topics are: parallel processing the content extraction and rule matching tasks. Ssl is a known security related protocol used as session layer for enhancing quite a lot of internet network services. Ganesh godavari have developed a linux based secure content switch based on openssl. We have identified that the ssl processing in the content switch is the main bottleneck through extensive benchmarking.

This project will be to explore the use of multiple ssl accelerators in improving the secure content switch performance. Explore the use server id parameter in openssl0.7 so that multiple content switch linux pc can be used as a unit. packet rewrite techniques they allow the web server to redirect web requests to other web servers when it is overloaded.

achieving web cluster performance through web page rewrite. i have a patent in rewriting web pages for achieving load balancing and performance in web server cluster. I am interested in some students implementing the ideas and compare its performance with that of content switch based web server cluster. Enhanced web service systems we have obtained the donation from intel, 4 cea7280 xml directors. I am interested in using these machines in projects that enhance the web services.

The related projects will be to compare the perform of such systems with those of lacs and ixpcs. Apply our linux kernel based content switch in storage area networks and explore the use 10gigabit metroethernet in san. Design and implement protocol software and api for supporting mulitpath routing. The protocol involves entities such as multiple path sender, multiple path receiver, and connection relay server. Connection relay server location problem: given a network topology or internet topology , find the optimal locations for n connection relay server. Substitute connection relay server with edge cache server then this becomes a server location problem in the content delivery network. Given a set of mirror sites say redhat mirror sites and a client location, find the optimal subset of mirror sites for parallel download of a package.

We need to choose faster servers with lighter load and bigger available bandwidth among them and the client. I have developed software for downloading software packages from multiple mirror sites concurrently. Investigate bandwidth measurement techniques that require low overhead, few probing messages, and good estimation results of bottleneck and available bandwidth. The research can be based on modified bprobe, cprobe, aprobe, pathchar, ping, traceroute tools. The techniques are critical in server/isp selection, billing, network control, network monitoring, and real time streaming applications.

Improve features and performance of irc aim and messenger and group support systems to support thousands of collaborative users simultaneously. Use multicast and concast filter/merge for reducing packet processing time and network load. Investigate ubiquitous web client/web server/cache server system extending esi for collaborative tasks. Extend the existing esi tags to allow multiple sources, filtering, and merging of data. Based on aparna yeddula's master project that use jsp/servlet to implement subset of esi for a dynamic cache server. Extend esi for supporting customization of web page layout fragments and collaborative tools that generate those web pages. Aparna yeddule's master project report on generate dynamic content on cache server.

Wireless security: investiage proposed wireless security standards, 802.1x/peap/ttls, develop software support on linux/windows clients and servers. The outgoing alternative routes can be easily established through those additional gateways, but we need to find ways new protocol, new architectures, or new techniques to route the legitimate traffic through those additional gateways. On such technique is the multiple path routing where traffic between a client and a server is going through a set of connection relay servers. It can be used to improve the performance multiple route gt higher aggregated bandwidth , the reliability duplicate packets over different routes , and the security the sender choose the routes that is less congested. Note that it is easy to reroute the outgoing traffic but it is harder to redirect existing or even future incoming traffic.

Develop a secure runtime/programming environment for studying the behavior of the virus and network worms. Web service was original proposed platform/language independent interface/system for integrating web services at different organizations/servers through http/soap/uddi. There are standards/groups that work very actively to specify protocols/apis that will address the security issues. This project will focus on the security risks and their solutions that cannot be addressed by just ssl.
