Performance Evaluation of Secure Call Admission Control for Multiclass Internet Services

With the growing demands for computer network communication, it becomes increasingly important to secure the data flow path. The existing research related to security mechanisms only focuses on securing the flow of information in the communication networks. There is a lack of work on improving the performance of networks to meet quality of service (QoS) constrains for various applications. The security mechanisms work by encryption and decryption of the information, but do not consider the optimised use of the network resources. In this paper we propose a secure call admission control (SCAC) for multiclass Internet services (MIS) to combine between security and quality of service. Our proposed secure call admission control for multiclass Internet services enhanced with malicious packets filter (MPF) is a set of technologies and solutions. It enforces security policy and bandwidth compliance on all devices seeking to access network computing resources, in order to limit damage from emerging security threats and to allow network access only to compliant and trusted endpoint devices. This SCAC also provides support for quality of service. High-level simulations and the related results are provided to show the properties of the SCAC.
