Quality of service (QoS) provisioning, in today's IP networks, is becoming more important due to the tremendous growth of real-time and multimedia applications. However, one of the challenges to achieving QoS requirements is how to allocate the bandwidth to various applications. One solution is to assigning bandwidth dynamically instead statically. In this paper, a reconfigurable bandwidth allocation technique based on QoS provisioning over DiffServ router is proposed. The technique aims at improving the performance and bandwidth utilization of multimedia applications by allowing video traffic class to share the bandwidth of other traffic classes that can tolerate a certain percentage of packet loss without any degradation of quality. This property is used to adjust the bandwidth assigned to video traffic according to the percentage of the packet loss of other classes. As a study case, the reconfigurable bandwidth allocation scheme is applied to a network model based on a modified deficit round robin (MDRR) scheduler. It can be seen from the simulation, using OPNET modeler 14.5, that the proposed QoS model improves the QoS of multimedia traffic.

A major demanding issue is developing a Service Level Agreement (SLA) based negotiation framework in the cloud. To provide personalized service access to consumers, a novel Automated Dynamic SLA Negotiation Framework (ADSLANF) is proposed using a dynamic SLA concept to negotiate on service terms and conditions. The existing frameworks exploit a direct negotiation mechanism where the provider and consumer can directly talk to each other, which may not be applicable in the future due to increasing demand on broker-based models. The proposed ADSLANF will take very less total negotiation time due to complicated negotiation mechanisms using a third-party broker agent. Also, a novel game theory decision system will suggest an optimal solution to the negotiating agent at the time of generating a proposal or counter proposal. This optimal suggestion will make the negotiating party aware of the optimal acceptance range of the proposal and avoid the negotiation break off by quickly reaching an agreement.
