Virtual routers on the move

Abstract

The complexity of network management is widely recognized as one of the biggest challenges facing the Internet today. Point solutions for individual problems further increase system complexity while not addressing the underlying causes. In this paper, we argue that many network-management problems stem from the same root cause-the need to maintain consistency between the physical and logical configuration of the routers. Hence, we propose VROOM (Virtual ROuters On the Move), a new network-management primitive that avoids unnecessary changes to the logical topology by allowing (virtual) routers to freely move from one physical node to another. In addition to simplifying existing network-management tasks like planned maintenance and service deployment, VROOM can also help tackle emerging challenges such as reducing energy consumption. We present the design, implementation, and evaluation of novel migration techniques for virtual routers with either hardware or software data planes. Our evaluation shows that VROOM is transparent to routing protocols and results in no performance impact on the data traffic when a hardware-based data plane is used.

Towards full network virtualization in horizontal IaaS federation: security issues

“…All the router architectures using the combination of data and control plane proposed by Pisa et al concentrates on performance in terms of delay [54]. The VROOM [55,56] router architecture also concentrates on the performance in terms of delay using control plane virtualization. Table 6 classifies the literature in two areas.…”

“…Chen et al uses VROOM [56] router architecture to provide energy-saving IP-WDM network architecture [83] by the process of virtual router migration. All the router architecture proposals and their migration methods using the combination of data and control plane proposed by Pisa et al concentrates on performance in terms of delay [54].…”

Challenges for Cloud Networking Security

“…Network virtualisation brings other advantages into stage. Such as the ability to reconfigure the network in real time without losing connectivity, to change the physical path or even to move one or more virtual nodes from one place to another [20].…”

OpenFlow and Xen-Based Virtual Network Migration

“…Such rearrangement can even promote changes in the virtual network topology. The primary objective is to move virtual nodes and links minimizing the impacts on the virtual networks, such as requiring virtual routers to be reconfigured, disturbing virtual IP-level topology, or increasing the convergence time of the virtual network routing algorithms due to message losses caused by the migration process [12].…”
