“…For one or more physical hosts connection, a cluster vSwitch is used as a centralized vSwitch that connects all the VMs of the cluster physical nodes. This vSwitch concept applies to all hypervisors [9]. However, the hypervisors are different to each other when it comes to live migration networking set up.…”

Live migration is an essential feature in virtual infrastructure and cloud computing datacenters. Using live migration, virtual machines can be online migrated from a physical machine to another with negligible service interruption. Load balance, power saving, dynamic resource allocation, and high availability algorithms in virtual data-centers and cloud computing environments are dependent on live migration. Live migration process has six phases that result in live migration cost. Several papers analyze and model live migration costs for different hypervisors, different kinds of workloads and different models of analysis. In addition, there are also many other papers that provide prediction techniques for live migration costs. It is a challenge for the reader to organize, classify, and compare live migration overhead research papers due to the broad focus of the papers in this domain. In this survey paper, we classify, analyze, and compare different papers that cover pre-copy live migration cost analysis and prediction from different angels to show the contributions and the drawbacks of each study. Papers classification helps the readers to get different studies details about a specific live migration cost parameter. The classification of the paper considers the papers’ research focus, methodology, the hypervisors, and the cost parameters. Papers analysis helps the readers to know which model can be used for which hypervisor and to know the techniques used for live migration cost analysis and prediction. Papers comparison shows the contributions, drawbacks, and the modeling differences by each paper in a table format that simplifies the comparison. Virtualized Data-center and cloud computing clusters admins can also make use of this paper to know which live migration cost prediction model can fit for their environments.

“…Unlike the classical approach of interconnecting network functions by a direct connection or through Layer 2 (L2) switches, a virtualized environment uses different approaches. In a virtualized environment, virtual machines can be connected in different scenarios [14]: 1) If two VNFs are on the same physical server and on the same local-access network (LAN), they would be connected through the same Vswitch.…”

Abstract-As mobile network users look forward to the connectivity speeds of 5G networks, service providers are facing challenges in complying with connectivity demands without substantial financial investments. Network Function Virtualization (NFV) is introduced as a new methodology that offers a way out of this bottleneck. NFV is poised to change the core structure of telecommunications infrastructure to be more cost-efficient. In this paper, we introduce a Network Function Virtualization framework, and discuss the challenges and requirements of its use in mobile networks. In particular, an NFV framework in the virtual environment is proposed. Moreover, in order to reduce signaling traffic and achieve better performance, this paper proposes a criterion to bundle multiple functions of virtualized evolved packet-core in a single physical device or a group of adjacent devices. The analysis shows that the proposed grouping can reduce the network control traffic by 70 percent.

“…Also, let P n be the internal path (e.g. virtual switches [36]) facilitating a medium of communication between these nodes inside the substrate nodev n . {P j } and {P j } are the sets of paths which bear outward and inward data flows of e k i from/to nodev n , respectively (note that the paths traversingv n in the middle of their routes are not included in either of these sets).…”
