中文摘要 | 在非同步傳輸網路中,根據使用者事先所宣告的訊務參數,文獻中提出各種使用 量參數管制機制,其中以漏桶式機制最有名。本論文分析網路多工器的效能,其中輸入訊務 在進入系統之前,均受到增強型漏桶式機制的調節,被監控的參數包括尖峰值封包速率、平 均封包速率與封包延遲變異。我們分析封包在多工器中所遭受的延遲上限與管制器參數的關 係。同時也證明上限的產生對於一致性的信物環境。 |
英文摘要 | In ATM networks, various usage parameter control (UPC) strategies are used to regulate incoming traffic according to the characteristics of the sources declared at call set-up. Among these UPC schemes, the Leaky Bucket method is well-known and has been discussed extensively. In this paper, we study the characteristics of the multiplexer in which cell arrivals are first policed by Enhanced Leaky-Buckets (ELBs) before entering the system. In addition to both policing mean cell rate and peak cell rate, cell delay variation (CDV) is also taken into consideration for each ELB. Based on the criteria of delay experienced in the buffer, we derive the upper delay bound expressed as a funtion of the ELB parameters. We also prove that the upper bound occurs with respect to a coincident token-generating pattern while the minimum of maximum queue delay occurs with respect to a perfectly interleaved token-generating pattern. |
