Network-based applications like video and voice over IP (VoIP), require guarantee of end-to-end QoS. The guarantee of end-to-end QoS requires an efficient resource management mechanism that can reserve/control resources like bandwidth, delay and jitter according to a policy for immediate and future resource utilization. Only a few resource management architectures called the resource manager (RM) have been implemented till today but all of them manage only the bandwidth in a network. We propose ENICOM's policy based resource manager (PREM) to address the above issues. PREM provides a set of useful API to make, cancel and change resource reservations and it can manage not only bandwidth but also delay and jitter which is possible mainly due to a highly efficient algorithm called the resource tracker (RTK). The RTK tracks resource reservation and availability in time using timeslices. We describe PREM and it's various components, which enable it to provide guarantee of end-to-end QoS in terms of bandwidth, delay and jitter
