Congestion Control Mechanism In GSM Telecommunication: A Review

The level of patronage being experienced in Global System for Mobile Communication (GSM) in Nigeria is overwhelming, this is due to the fact that GSM is been used by anyone , anytime and everywhere .This led to a lot of congestion in network resulting to bandwidth degradation and decrease in quality of services. This research has developed a management algorithm for the management of the GSM congestion and evaluated the algorithm based on their performance, Call admission control was combined with other GSM congestion control mechanism to achieve a good and better result. The work integrates all the algorithms together in order to manage the congestion considering all the strengths and constraints of each algorithm

Security Framework for Storage Area Network (SAN)

Over the years, storage network technology has been faced with significant changes and there are recent innovations trying to improve the level of service and reliability in storage area network.  The need for storage of data and information as well as the increase of security awareness in the general population has brought the concept of Storage Area Network to the forefront. Fibre Channel SANs have become the backbone for serving the information needs of enterprise data centers.This paper presents an overview of SAN technology which is implemented using fibre channel technology, securing a Storage Area Network by using best practices in setting up a SAN. New security protocol called DH CHAP (Diffie Hellman challenge handshake   authentication protocol) are implemented to counter  the threats and protect data authenticity, confidentiality and integrity.
