This research proposes an OpenFlow (OF) segment routing (SR) control-plane software-defined network (SDN) to reduce the number of control messages between the source and destination hosts. In the study, the conventional OpenFlow SDN and the proposed OpenFlow SR SDN were emulated and assessed under three network configurations: tube, shortest path and load balance. The results revealed that the number...
This research paper proposes IEEE802.3az incorporated green algorithmic schemes on the software defined networking-based segment routing (SDN-based SR) centralized network. The proposed schemes are the green (i.e. the EAGER and CARE metrics) SDN-based SR networks with and without traffic engineering (TE) tunneling. Green metrics extend the IEEE 802.3az energy saving to the whole network, while tunneling...
IEEE 802.3az, the recent standard for Energy Efficient Ethernet, is one of the main contributions of the ICT industry to the global quest for energy efficiency. Energy consumption reduction is accomplished by essentially replacing the continuous IDLE of legacy IEEE 802.3 cards with a Low Power Idle. While this is an important step in the right direction, studies have shown that the energy saving with...
