Investigating the Potential of the Inter-IXP Multigraph for the Provisioning of Guaranteed End-to-End Services
Proceedings of the 2015 ACM SIGMETRICS International Conference on Measurement and Modeling of Computer Systems(2016)
摘要
In this work, we propose utilizing the rich connectivity between IXPs and ISPs for inter-domain path stitching, supervised by centralized QoS brokers. In this context, we highlight a novel abstraction of the Internet topology, i.e., the inter-IXP multigraph composed of IXPs and paths crossing the domains of their shared member ISPs. This can potentially serve as a dense Internet-wide substrate for provisioning guaranteed end-to-end (e2e) services with high path diversity and global IPv4 address space reach. We thus map the IXP multigraph, evaluate its potential, and introduce a rich algorithmic framework for path stitching on such graph structures.
