本文讨论了一个基于主题的发布/订阅(PS)系统的对等模型(P2P模型)，其中每个对等进程(Peer)都可以订阅和发布带有主题的事件消息，并且没有集中式协调器。每个对等点必须因果地传递该对等点感兴趣的事件消息。在我们以前的研究中，基于主题的原因传递(TBC)协议被提出用于同构同步网络，其中每对节点之间的最大延迟时间相同，并且每个对等点的最大时钟偏移相同。在本文中，我们提出了一种异质TBC(HTBC)协议，该协议中的对等点之间的最大延迟时间和每个对等点的最大时钟偏移量可能不相同。在评估中，我们表明HTBC协议减少了不必要排序的事件消息对的数量。
In this paper, we discuss a peer-to-peer (P2P) model of a topic-based publish/subscribe (PS) system (P2PPS model) where each peer process (peer) can both subscribe and publish event messages with topics and there is no centralized coordinator. Each peer has to causally deliver event messages in which the peer is interested. In our previous studies, the TBC (topic-based causally delivery) protocol is proposed for a homogeneous synchronous network where maximum delay time between every pair of peers is the same and the maximum clock offset of each peer is the same. In this paper, we propose a heterogeneous TBC (HTBC) protocol where peers are interconnected in heterogeneous networks where maximum delay time between every pair of peers and maximum clock offset of each peer may not be the same. In the evaluation, we show the number of pairs of event messages unnecessarily ordered is reduced in the HTBC protocol.
