网络八卦时代

The Age of Gossip in Networks

Roy D. Yates

摘要:

源节点作为点过程更新其状态,并且还将其更新转发到观察者节点的网络。在观察者网络中,这些更新作为点过程从节点转发到节点。每个节点都希望尽可能及时地了解源。在这个网络中,及时性是通过离散形式的信息年龄来衡量的:源的每个状态更改都被称为版本,节点的年龄是有多少版本是来自源的最新更新。这项工作介绍了一种方法,用于评估在网络中的每个节点的平均版本年龄时,节点使用无记忆八卦协议转发更新。然后,通过对一组简单网络的版本年龄分析,证明了这种方法。对于具有对称更新率的完全图上的流言,证明了每个节点的平均年龄随网络规模的对数增长。

英文摘要:

A source node updates its status as a point process and also forwards its updates to a network of observer nodes. Within the network of observers, these updates are forwarded as point processes from node to node. Each node wishes its knowledge of the source to be as timely as possible. In this network, timeliness is measured by a discrete form of age of information: each status change at the source is referred to as a version and the age at a node is how many versions out of date is its most recent update from the source. This work introduces a method for evaluating the average version age at each node in the network when nodes forward updates using a memoryless gossip protocol. This method is then demonstrated by version age analysis for a collection of simple networks. For gossip on a complete graph with symmetric updating rates, it is shown that each node has average age that grows as the logarithm of the network size.
