网络测试床映射问题是将仿真网络映射到测试集群(如Emulab或DETER)的问题。在本文中,我们证明了网络测试床映射问题是({mathcal NP})-完全的集群交换机之间的带宽有约束时。我们证明,当带宽不受约束时,这个问题是微不足道的,并注意到一些新的数据中心网络的建议已经消除了这一障碍。最后,我们考虑在带宽有限的情况下,新的算法。
The Network Testbed Mapping Problem is the problem of mapping an emulated network into a test cluster such as Emulab or DETER. In this paper, we demonstrate that the Network Testbed Mapping Problem is ({mathcal NP})-complete when there is constrained bandwidth between cluster switches. We demonstrate that the problem is trivial when bandwidth is unconstrained, and note that a number of new proposals for data center networking have removed this barrier. Finally, we consider new heuristics in the bandwidth-limited case.
