Abstract
Current communication and network infrastructures have created billions of petabytes of data on the network every second. This imposes challenging traffic demands as a major research problem. This paper proposes a scheme for Cloud-of-Things and Edge Computing (CoTEC) traffic management in multi-domain networks. In order to direct the traffic flows through the service nodes in multi-domain networks, we assign the critical egress point for each traffic flow in the CoTEC network with multiple egress routers to optimize CoTEC traffic flows known as Egress-Topology (ET). Therefore, the proposed ET topology incorporates traditional Multi-Topology Routing (MTR) in the CoTEC network to address the inconsistencies between service overlay routing and the Border Gateway Protocol (BGP) policies. Furthermore, the proposed ET introduces a number of programmable nodes which can be configured to ease of ongoing traffic on the network, and re-align services among the other nodes in multi-domain networks. Results show that our optimization algorithm has lower execution time and better QoS than without using optimization algorithm, thus allowing us to meet the demand of flexibility and efficiency of multi-domain networks in comparisons to justify our research contributions.
