International Journal of Network Management

Modern computer networks and communication systems are increasing in size, scope, and heterogeneity. The promise of a single end-to-end technology has not been realized and likely never will occur. The decreasing cost of bandwidth is increasing the possible applications of computer networks and communication systems to entirely new domains. Problems in integrating heterogeneous wired and wireless technologies, ensuring security and quality of service, and reliably operating large-scale systems including the inclusion of cloud computing have all emerged as important topics.

    This paper presents a generic policy-aware virtual machine management framework, PAVM, to improve resource allocations in a cloud computing platform. The PAVM framework provides both the efficient means to profile different VM affinities and the mechanisms to exploit profiled affinities to achieve desired management goals as governed by the provider-defined policies. A comprehensive evaluation using simulations and real-world experiments confirms the feasibility of the proposed framework and associated algorithms.

    OpenCAPWAP 2.0 is the new open-source implementation of the CAPWAP protocol. OpenCAPWAP 2.0 improves stability, reliability, maintainability, and the compliance with the standard. OpenCAPWAP 2.0 implements both Local and Split MAC architectures and supports the centralized management, by an access controller (AC), of hotspot of wireless termination points (WTPs). It implements the local and remote management of stations and configuration of network parameters. OpenCAPWAP 2.0 simplifies the implementation of sophisticated network management policies that include frequency distribution, load balancing of users, and QoS.

  3. Simple, efficient location-based routing for data center network using IP address hierarchy

    Many alternative routing protocols are proposed to overcome the scalability problem of conventional routing protocols for data center networks. But, these protocols, in the process of fixing the scalability prob lem, introduced additional complexities such as large network control over head and re-programming of network elements. In our work, we present a new location-based routing based on IP address hierarchy that overcomes these problems. We demonstrate our proposed location-based routing on our proposed architecture.

  5. ReversePTP: A clock synchronization scheme for software-defined networks (pages 355–372)

    This paper introduces ReversePTP, a clock synchronization scheme for software-defined networks (SDN). ReversePTP is based on the Precision Time Protocol (PTP), but is conceptually reversed; in ReversePTP all nodes (switches) in the network distribute timing information to a single software-based central node (the SDN controller) that tracks the state of all the clocks in the network. In accordance with the SDN paradigm, the ‘brain’ is implemented in software, making ReversePTP flexible and programmable from an SDN programmer's perspective.
