由於社會資訊流型態的改變及要求快速的傳送時代來臨,網路的需求與日俱增,在資訊傳送速度與頻寬方面的需求也越來越高,但是並沒有無限的頻寬可提供給訊務傳送,因此,如何以有限的資源達到最有效的網路使用效率就是本文的主要目的。而且現在的訊務類型多為多媒體資訊,也就是語音、影像、數據資料、圖片等的結合,如何有效且迅速地將之送往各個端點,將是一大挑戰。
為了快速的傳送訊務,本研究是以預先建構路由表的方式來達到迅速搜尋路由的目的。另外,傳統的方式是將頻寬計算與配置,以及路由選擇這兩項機制分開來考慮,但是這樣的缺點是考慮了個別的最佳化,並不見得是整體的最佳化,所以本研究將兩個機制同時考慮,以達到整體最佳化的目的。並且以模擬軟體模擬實際訊務傳送的過程,再將收集到的數據做分析,驗證本方法的可行性與優缺點。

Because of the change of the society-information-flow type and the coming of fast-transpotation era, the requirement of the network is steadily on the increase, and the one of the delivering speed and bandwidth also become higher and higher. But there is no infinite bandwidth to be provided to the traffic transmission. Therefore, how to use network most efficiently with limited resource is the main purpose. And most of type of traffics is multimedia now; that is the combination of sounds, images, data, pictures...etc. How to transfer to each node efficiently and quickly will be a big challenge.
To bring out the fastest traffic transmission, this research constructs the routing table to search routing quickly. Besides, on considering the calculation and location of bandwidth, and routing selection is separate in traditional way, but there will be such a weakness that it could just consider the individual optimization, not exactly the whole optimization. So this research considers two mechanisms together to reach the whole optimization. And it’s also going to simulate the actual process of traffic transmission by the simulation software, then to analysis the collected data to identify the feasibility, merit and shortcomings of the heuristic method in this research.
