由於網際網路規約使用的普及化，長久以來，提出一個適宜的光學網際網路解決方案以期能夠有效地且有彈性地利用光纖的超高頻寬容載劇增中的根基於網際網路之應用程式一直是一個關係重大的課題。事實上，此課題的核心乃在於交換型式的設計。在這份博士論文中，我們主要是探討在具波長轉換能力的光波分割多工網路上，以兩種交換型式為基礎，進行動態繞徑的相關研究；這兩種交換型式一是波長繞徑，另一則是光波巨量資料單位交換.
光波分割多工網路的興起是由波長繞徑的觀念開始的，而運用這項技術的網路就稱作波長繞徑網路。針對波長繞徑網路，我們提出了一個有調適性的繞徑策略名為加權最短花費路徑策略。此策略不僅考慮了連接線的花費與波長轉換所需的花費，而且也將負載平衡的效用納入考量。因此，這個策略目的在於尋找一個能夠將資源花費最小化，同時又能夠將所有連接線上的流量負載儘可能維持平衡的路徑。過程中，我們利用了一種輔助圖以提供連線建立與釋出的演算法。

光波巨量資料單位交換是一種進年來新興的交換型式，它能夠解決波長繞徑方式中頻寬無法有效利用的問題。在眾多的光波巨量資料單位交換規約中，及時規約是較為人所知的一個。一般而言，緩衝器需求對以及時規約為基礎的光波巨量資料單位交換來說並非不可缺少的。然而，若要提供轉向繞徑，則必須要有光學緩衝器存在以解決時距不足的問題。因此，本論文的的另一個研究主題是探討如何在光波巨量資料單位交換網路上支援轉向繞徑。我們提出了兩個能夠處理轉向繞徑的光學交換器架構以及幾個解決時距不足問題的可能方案。
