CIT - Enhancing Security, Scalability and Flexibility of Virtual Private LAN Services
2017 IEEE International Conference on Computer and Information Technology (CIT), 2017Co-Authors: Madhusanka Liyanage, Mika Ylianttila, Andrei GurtovAbstract:Ethernet based VPLS (Virtual Private LAN Service) networks are now becoming attractive in many enterprise applications due to simple, protocol-independent and cost efficient operation. However, new VPLS applications demand additional requirements, such as elevated security, enhanced scalability and improved flexibility. This paper summarized the results of a thesis which focused to increase the scalability, flexibility and compatibility of secure VPLS networks. First, we propose a scalable secure flat-VPLS architecture based on Host Identity Protocol (HIP) to increase the forwarding and security plane scalability. Then, a secure hierarchical-VPLS architecture has been proposed by extending the previous proposal to achieve control plane scalability as well. To solve the compatibility issues of Spanning Tree Protocol (STP) in VPLS networks, a novel Distributed STP (DSTP) is proposed. Lastly, we propose a novel SDN (Software Defined Networking) based VPLS (SoftVPLS) architecture to overcome Tunnel Management limitations in legacy secure VPLS architectures. Simulation models and testbed implementations are used to verify the performance of proposed solutions.

improving the Tunnel Management performance of secure vpls architectures with sdn
Consumer Communications and Networking Conference, 2016Co-Authors: Madhusanka Liyanage, Mika Ylianttila, Andrei GurtovAbstract:Secure VPLS (Virtual Private LAN Services) networks are becoming attractive in many Enterprise applications. However, the Tunnel establishment mechanisms of legacy VPLS architectures are static, complex and inflexible in nature. As a result, secure VPLS architectures are suffering from limitations such as the limited scalability, over utilization of network resources, high Tunnel establishment delay and high operational cost. In this article, we propose a novel SDN (Software Defined Networking) based VPLS (Virtual Private LAN Services) architecture to overcome Tunnel Management limitations in existing secure VPLS architectures. The proposed architecture utilizes IPsec enabled OpenFlow switches as PEs (Provider Edge Equipments) and OpenFlow protocol to install flow rules in PEs. A centralized controller is used to manage the Tunnel establishment functions. We also propose a novel Tunnel Management mechanism which can estimate the Tunnel duration based on real time session characteristics. Moreover, a novel Tunnel resumption mechanism is proposed to reduce the Tunnel establishment delay of subsequent Tunnel establishments. Finally, the performance of proposed architecture is analyzed by using a simulation model and a testbed implementation.

Dynamic Tunnel Management protocol for IPv4 traversal of IPv6 mobile network
IEEE 60th Vehicular Technology Conference 2004. VTC2004-Fall. 2004, 1Co-Authors: Jaehoon Jeong, Jungsoo Park, Hyounjun KimAbstract:The paper specifies a mechanism for enabling IPv6 mobile network containing mobile network nodes to traverse through IPv4 networks that are comprised of wireless LAN, CDMA and GPRS. The traversal is possible by a dynamic Tunnel Management protocol that dynamically updates the information of Tunnel end point between mobile router and home agent, including a new IPv4 address of the mobile router.

Integration of Life-Cycle Cost Analysis with Bridge Management Systems: Case Study of Swedish Bridge and Tunnel Management System
Transportation Research Record, 2012Co-Authors: Mohammed Safi, Håkan Sundquist, Raid Karoumi, George RacutanuAbstract:Many countries use bridge Management systems (BMSs), and many of these systems involve some form of life-cycle cost (LCC) analysis. Use of LCC analysis in bridge engineering is rare, however; the technique has been applied primarily in the operation phase to support decisions about bridges that already exist. Yet LCC analysis can be applied across the life of a bridge. This paper introduces the Swedish Bridge and Tunnel Management System (BaTMan). A comprehensive, integrated LCC implementation scheme takes into account the bridge investment and Management processes in Sweden. The basic economic analytical tools as well as other helpful LCC analysis techniques are described. A case study demonstrates improvements in BaTMan as a factor in the decision whether to repair or to replace a bridge. Cost records for 1,987 bridges were used as input data in the case study. On the basis of the same records, the average real and anticipated initial costs of various bridge types in Sweden are presented schematically.
