Building optimal virtual networks across multiple domains is an essential technology to offer flexible network services. However, existing research unrealistically assumes that providers will share their private information. Providers, as is well known, never actually do that to remain competitive. Technically, secure multi-party computation, which is a cryptographic tool, can be used to secure optimization, but it is too time-consuming. This paper presents a novel method to optimize virtual networks built over multiple domains, with great efficiency but without revealing any private information. Our method employs secure multi-party computation but only for masking sensitive values to evade time-consuming computation. It is solidly based on the theory of optimality, and is assured of finding reasonably optimal solutions. Experiments show that our method finds nearly optimal solutions in just a few minutes for virtual network with tens of nodes. |
