资源发现的DeterministicWorst-Case消息复杂度优化方案

A DeterministicWorst-Case Message Complexity Optimal Solution for Resource Discovery

Sebastian Kniesburges, Andreas Koutsopoulos, Christian Scheideler

摘要:

我们考虑分布式系统中的资源发现问题。特别是,我们给出了一个算法,使得网络中的每个节点发现网络中任何其他节点的地址。我们将节点的知识建模为由有向图给出的虚拟覆盖网络,使得所有节点的完整知识对应于覆盖网络中的完整图。虽然有几个解决方案的资源发现,我们的解决方案是第一个实现最坏情况下的最佳工作为每个节点,即地址的数量(O(n))或位(O(n log n))节点接收或发送符合下限,同时确保只有一个线性运行时间(O(n))轮数。

英文摘要:

We consider the problem of resource discovery in distributed systems. In particular we give an algorithm, such that each node in a network discovers the address of any other node in the network. We model the knowledge of the nodes as a virtual overlay network given by a directed graph such that complete knowledge of all nodes corresponds to a complete graph in the overlay network. Although there are several solutions for resource discovery, our solution is the first that achieves worst-case optimal work for each node, i.e. the number of addresses (O(n)) or bits (O(n log n)) a node receives or sends coincides with the lower bound, while ensuring only a linear runtime (O(n)) on the number of rounds.
