Papillon:环上的贪婪路由

Papillon: Greedy Routing in Rings

Ittai Abraham, Dahlia Malkhi, Gurmeet Singh Manku

摘要:

我们研究了环中$n$节点上的{ \sc greedy}路由问题,其中两个节点之间的\emph{distance}定义为沿环的顺时针方向或它们之间的绝对距离.这样的图出现在社交网络建模的上下文中以及对等系统的路由网络中。我们构建了第一个网络的$n$节点,其中{ \sc贪婪}路由需要$O(\log n / \log d)$跳在最坏的情况下,与$d$每个节点的出站链路。我们的结果有第一个渐近最优的贪婪路由复杂度。以前的构造需要$O(\frac{\log^2 n}{d})$跳。

英文摘要:

We study {\sc greedy} routing over $n$ nodes placed in a ring, with the \emph{distance} between two nodes defined to be the clockwise or the absolute distance between them along the ring. Such graphs arise in the context of modeling social networks and in routing networks for peer-to-peer systems. We construct the first network over $n$ nodes in which {\sc greedy} routing takes $O(\log n / \log d)$ hops in the worst-case, with $d$ out-going links per node. Our result has the first asymptotically optimal greedy routing complexity. Previous constructions required $O(\frac{\log^2 n}{d})$ hops.
