Software Defined Networking (SDN) is a paradigm shift technology in networking. However, it is not practical to remove existing networks for building SDN networks or to replace all operating network devices with SDN-enabled devices. Therefore, SDN migration, which implies co-existing techniques and gradually moving to SDN, is an important issue. In this paper, we focus on how to integrate SDN networks...
In computer networking, broadcasting means to transmit a packet to every device in one broadcast domain. Broadcasting is widely used in many protocols, like ARP [1], DHCP [2] and so on. The main reason is that in a distributed network, each node has no knowledge about the whole network. Therefore, the node has to use broadcast ways to build its knowledge. However, for those who do not need to get...
In this paper, a novel mobile agent based topology discovery protocol is proposed for mobile ad hoc networks. Unlike existing protocols which also utilize mobile agents to collect topology information, the proposed protocol not only considers the fairness of the node visitation time by the agents, but also takes the frequency topology changes into consideration. The protocol optimizes the migrating...
Security protocols provide the basic guarantee to open network of secure communications, but practice proved that the analysis and design of a protocol is not easy even it is very simple. The paper describes an automatic design approach of network security protocols based on the evolutionary algorithm and BEN logic and illustrates the approach can automatic design large-scale security protocols, such...
Data mining has been a popular research area for more than a decade because of its ability of efficiently extracting statistics and trends from large sets of data. However, in many applications, the data are originally collected at different sites owned by different users. The distributed data mining raises concerns about the privacy of individuals. This paper considers the problem of privacy preserving...
