通过无缓冲区的位

Bits Through Bufferless Queues

Mehrnaz Tavan, Roy D. Yates, Waheed U. Bajwa

摘要:

本文研究了服务时间独立同分布的排队系统中,连续数据包通过队列的时间来传递信息的信道容量。这种定时信道通常是在工作守恒队列的假设下研究的。与此相反,本文研究的情况下,一个无缓冲队列,下降到达的数据包,而一个数据包是在服务。在此无缓冲模型下,本文给出了定时信道容量的上界,并建立了无缓冲M/M/1和M/G/1排队情况下的可达速率。特别是,与M/M/1工作保留队列相比,无缓冲区M/M/1队列在最坏的情况下容量减少不到10%。

英文摘要:

This paper investigates the capacity of a channel in which information is conveyed by the timing of consecutive packets passing through a queue with independent and identically distributed service times. Such timing channels are commonly studied under the assumption of a work-conserving queue. In contrast, this paper studies the case of a bufferless queue that drops arriving packets while a packet is in service. Under this bufferless model, the paper provides upper bounds on the capacity of timing channels and establishes achievable rates for the case of bufferless M/M/1 and M/G/1 queues. In particular, it is shown that a bufferless M/M/1 queue at worst suffers less than 10% reduction in capacity when compared to an M/M/1 work-conserving queue.
