We proposed theUniversal Cloud Classification (UCC) as a universal scheme to uniquely identify each cloud provider, service and tenant across the global Internet. UCC IDs can be embedded in IP packet headers for traffic classification, which can support a variety of routing, QoS and security applications for data centres, inter-cloud routing and IoT. Cisco has filed a series of patents based on the concept of UCC.
BGP-Multipath routing in the Internet
BGP-Multipath (BGP-M) is a multipath routing technique for load balancing. Distinct from other techniques deployed at a router inside an Autonomous System (AS), BGP-M is deployed at a border router that has installed multiple interdomain border links to a neighbour AS. We provided the first measurement and a comprehensive analysis of BGP-M routing in the Internet. We revealed that BGP-M has already been extensively deployed and used in the Internet. This study provided the state-of-the-art knowledge on BGP-M with novel insights into the unique features and the distinct advantages of BGP-M as an effective and readily available technique for load balancing.
