延迟/中断容忍网络(DTN)在未来空间活动的信息基础设施中发挥着重要作用,如星际互联网(IPN)或太阳系互联网(SSI)。在这种长距离和间歇性的链路上,DTN技术通过典型的保管、传输和存储转发机制使科学数据端到端可靠地返回。由于没有足够的空间航天器部署到DTN,现在和近几十年,将会有一些中间节点作为DTN路由器承载很大比例的网络流量。因此,在中间节点中管理包的行为和能力会对空间DTN上的数据传输产生影响。针对DTN中间节点的捆包交付行为,提出了一种基于二维马尔可夫链的分析框架。在此基础上,分别建立了空间DTN上束传输的延迟模型和传输成功概率模型,两者都与节点存储的停留时间密切相关。评价结果表明:(1)将源文件分成更大的包进行传输,导致中间节点的存储占用时间更长;(2)束大小对节点存储占用时间的影响比段大小更明显;(3)与LTP段大小相比,数据包的传输成功概率更依赖于DTN数据包的大小。
Delay/disruption tolerant network (DTN) plays a promising role in prospected information infrastructures for future space activities, such as Interplanetary Internet (IPN) or Solar System Internet (SSI). Over such long-haul and intermittent links, DTN technique makes scientific data return end-to-end reliable by the typical custody transfer and store-and-forward mechanism. Due to lack of enough space spacecrafts deployed for DTN, now and in the near decades, there will be some intermediary nodes which would carry a large proportion of network traffic as DTN routers. Consequently, the behaviors and capabilities of managing bundles in the intermediary nodes would have impacts on the data transport over space DTN. Focusing on the storage dynamics of bundles, in this paper, we propose an analytical framework based on two-dimension Markov chain to evaluate the behaviors of bundles delivery in DTN intermediate nodes. Accordingly, a delay model and a transmission success probability model for bundles delivery over space DTN are developed separately, both dependent closely on the sojourn time in node storages. The evaluation results indicate that: (1) Dividing the source files into bigger bundles for transmission causes a longer storage-occupancy time on intermediary nodes; (2) bundle sizes have more explicit impacts on the storage-occupancy time at a node than segment sizes do; and (3) the transmission success probability of a bundle is more dependent on a DTN bundle size than on a LTP segment size.
