Dr. Rawal Publishes Articles in Computer Science Journal

Bharat Rawal, Ph.D.January 15, 2014 - Dr. Bharat Rawal, assistant professor of computer science in the Department of Computer Science and Information Systems, has published "Paper ID 7013 Applications of Split Protocol"  in the International Journal of Computers and Their Applications (IJCA) and "Extended Version of Augmented Split-protocol; An Ultimate DDoS Defender" in the International Journal on Computational Science and Applications (IJCSA). In addition, Dr. Rawal was nominated for the 2013 John Robert Gregg Award, the most prestigious honor in business education that recognizes lifetime achievement in the field.

In the IJCA article, Dr. Rawal and co-authors studied the concept of splitting a protocol into two sub-entities. In addition, the article also served as a single source of knowledge for split protocol concept and its broader impact on future network architectures, designs and implementations. The full abstract noted: A protocol is considered to be in-separable entity between two communicating parties. This paper proposes a novel concept that changes the definition of protocols by splitting a protocol into two sub-entities. This proposed architecture performs identical functions as a non-split protocol system and builds a foundation for many innovative ideas that are not envisioned in a non-split protocol system. The split protocol concept and its motivations are presented here. The concept is explored in implementing client server architectures, mini-cluster configurations and migratory servers. Attributes such as improvement in server performance, constructing a variety of mini-cluster configurations to serve large workloads, building clusters without using expensive partitioning strategies, achieving simpler migratory servers and enriching client server architectures to accommodate client splitting and achieving inherent reliability in server designs have being found in the split concept. The above novel features are illustrated in this paper by describing architecture, design and implementation of Web server and client applications. In addition, this paper also serves as a single source of knowledge for split protocol concept and its broader impact on future network architectures, designs and implementations.

For the IJCSA publication, Dr. Rawal and co-authors presented the concept and performance of Augmented Split-protocol (ASp) as a defensive tool against Distributed Denials of Service (DDoS) attacks. The full abstract noted: Distributed Denials of Service (DDoS) attacks have become the daunting problem for businesses, state administrator and computer system users. Prevention and detection of a DDoS attack is a major research topic for researchers throughout the world. As new remedies are developed to prevent or mitigate DDoS attacks, invaders are continually evolving new methods to circumvent these new procedures.  In this paper, we describe various DDoS attack mechanisms, categories, scope of DDoS attacks and their existing countermeasures. In response, we propose to introduce DDoS resistant Augmented Split-protocol (ASp). The migratory nature and   role changeover ability of servers in Split-protocol architecture will avoid bottleneck at the server side. It also offers the unique ability to avoid server saturation and compromise from DDoS attacks. The goal of this paper is to present the concept and performance of (ASp) as a defensive tool against DDoS attacks.
