End-to-end route control spanning a set of networks can provide opportunities to both end users to optimize interdomain control and network service providers to increase business offering. BGP, the de facto interdomain routing protocol, provides no …
Multi-domain network resource reservation systems are being deployed, driven by the demand and substantial benefits of providing predictable network resources. However, a major lack of existing systems is their coarse granularity, due to the …
As modern network applications (e.g., large data analytics) become more distributed and can conduct application-layer traffic adaptation, they demand better network visibility to better orchestrate their data flows. As a result, the ability to …
Recently, a number of multi-domain network resource information and reservation systems have been developed and deployed, driven by the demand and substantial benefits of providing predictable network resources. A major lacking of such systems, …
Interdomain routing using BGP is widely deployed and well understood. The deployment of SDN in BGP domain networks, however, has not been systematically studied. In this paper, we first show that the use-announcement inconsistency is a fundamental …
As many applications today migrate to distributed computing and cloud platforms, their user experience depends heavily on network performance. Software Defined Networking (SDN) makes it possible to obtain a global view of the network, introducing the …
Providing an interface for network applications to access network state, Software-Defined Networking (SDN) northbound API protocol is the foundation for the development of programmable networks with adaptive applications. However, with the growing …
