With the increasing demand for computer communications the need for security is growing dramatically. The existing research related to security mechanisms focuses on security of the data transmission in the communication networks only. The developed specific Secure Call Admission Control (SCAC) is a set of technologies and solutions to enforce 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. IPSec is a suite of protocols that adds security to communications at the IP level. Protocols within the IPSec suite make extensive use of cryptographic algorithms.
