Internet Protocol Multimedia Subsystem (IMS) merupakan suatu arsitektur topologi framework untuk mengirimkan layanan Multimedia berbasiskan IP (Internet Protocol), yang telah menjadi arsitektur framework terkemuka yang sebagai enabler dari operator untuk menawarkan layanan VoIP dan layanan multimedia. Precopy Live Migration merupakan proses migrasi yang diterapkan pada IMS dengan cara page memory pada VM ditransmisikan pada fase iterasi ketika VM sedang dalam state running pada host sumber. Kemudian VM pada sumber di suspend menggunakan fase stop-and-copy dan sisa page memory ditransmisikan menuju host tujuan. Penelitian ini berfokus pada bagaimana IMS tetap dapat melayani pada saat terjadinya migrasi. Downtime yang terlalu lama akan berakibat pada pelayanan dari servis IMS tidak maksimal. Parameter yang akan diuji adalah Downtime, Waktu Migrasi, dan Jumlah data yang di transfer. Internet Protocol Multimedia Subsystem (IMS) is a framework architect topology to delivery multimedia services (Internet Protocol) based which has become the latest architect framework as operator services enabler that provide VoIP and Multimedia services. Precopy Live Migration implemented to IMS with VM’s memory pages are transmitted in the iteration phase, while the VM is still running at the source. After that, the VM is suspended in the stop- and-copy phase, and the remaining pages are transmitted to the destination. This research focused on how IMS can provide user during migration process. Longest downtime process will impact on service level to user. During migration process, Downtime, Migration Time, and Amount transferred data were evaluated. Keywords: downtime, migration, IMS, Virtual, precopy live migration

Migration Technique

In virtualized servers, with live migration technique pages are copied from one physical machine to another while the virtual machine (VM) is running. The dynamic migration of virtual machines encumbers the data center which in turn reduces the performance of applications running on that particular physical machine. A considerable number of studies have been carried out in the area of performance evaluation during live VM migration.  However, all the aspects related to the migration process have not been examined for the performance assessment. In this paper, we propose a novel approach to evaluate the performance during migration process in different types of coupled machine environment. It is presented here that the state of art VM migration technology requires further improvement in realizing effective migration by monitoring comprehensive performance value. We introduced the parameter, θ, to compare performance value which can be used for controlling and halting unsuccessful migration and save significant amount of time in migration operation.  Our model is capable of analyzing real time scenario of cloud performance assessment targeting VM migration strategies. It also offers the possibility of further expanding to universal models for analyzing the performance variations that occurs as a result of VM migration.

And Migration

It has already been proven that VMs are over-utilized in the initial stages and are underutilized in the later stages. Due to the random utilization of the CPU, resources are sometimes heavily loaded whereas other resources are idle. Load imbalance causes service level agreement (SLA) violations resulting in poor quality of service (QoS) aided by the imperfect management of resources. An effective load balancing mechanism helps to achieve balanced utilization, which maximizes the throughput, availability, and reliability and reduces the response and migration time. The proposed algorithm can effectively minimize the response and the migration time and maximize reliability, and throughput. This research also helps to understand the load balancing policies and analysis of other research works.

Total Migration

The live migration of virtual machine (VM) is an important technology of cloud computing. Down-time, total migration time and network traffic data are the key measures of performance. Through the analysis of dynamic memory state of a virtual machine migration process, we propose a dirty pages algorithm prediction based on pre-copy to avoid dirty pages re transmission. Experimental results show that, compared with the Xen virtual machine live migration method adopted, our method can at least reduce 15.1% of the total amount of data and 12.2% of the total migration time.

Total Migration

Cloud applications and services such as social networks, file sharing services, and file storage have become increasingly popular among users in recent years. This leads to the enlargement of data centers, and an increase in the number of servers and virtual machines. In such systems, live migration is used to move virtual machines from one server to another, which affects the quality of service. Therefore, the problem of finding the total migration time is relevant. This article proposes analytical approach to obtaining analytical expression of the probability density of the total migration time based on the use of the apparatus of characteristic functions. The obtained expression is used to calculate characteristics of migration, taking into account the applications contributing the most randomness to the total migration time. To simplify the calculation of migration characteristics, the use of the Laguerre series can be recommended as giving more reliable results compared to Gram-Charlier series.

Multimedia becomes one of the most wanted content in the modern Internet world. Since the Mobile Internet Protocol version 6 (MIPv6) was proposed, many researchers have tried to develop a new protocol based on this technology in order to improve the performance of mobile multimedia services. The world is emerging toward the Mobile Internet Protocol Television (MIPTV) era where people are enabled to watch television while roaming. The MIPTV technology requires high bandwidth and low latency handover. This paper proposes a new model of secure and robust handover with low handover latency, called SeamSAR. The model introduces a new way to perform home binding update and correspondent binding update simultaneously. Simulation results show that the proposed model reduced the handover latency to 63% compared to FMIPv6. Moreover, the secureness of the proposed model was verified using CMurphi simulator.
