As the heterogeneity of end systems and their networking applications grows, networking challenges to meet the various requirements of traffics from different applications should be coped with new networking features, not possible in today's Internet. OpenFlow proposes an open programmable interface to leverage more network controllability by separating control and data path of a network device and...
OpenFlow protocol allows researchers to use programmable networking techniques to flexibly assign networking resources and manage network traffic according to user demands. In this paper, by taking SAGE Visualcasting as an example user application, we propose that OpenFlow-based programmable networking can be interactively utilized together with other monitoring schemes to enhance the performance...
In this letter, we propose a decentralized group key management algorithm called DECLKH, which combines the logical key hierarchy (LKH) and the tree-based group Diffie- Hellman (TGDH) schemes. LKH is a centralized key distribution scheme, and thus, lacks fault-tolerance. On the other hand, TGDH is relatively inferior in terms of performance to LKH although it is fault-tolerant. The proposed algorithm,...
