A tree topology combines characteristics of linear bus and star topologies. It consists of groups of star-configured workstations connected to a linear bus backbone cable. Tree topologies allow for the expansion of an existing network, and enable schools to configure a network to meet their needs.
樹狀拓樸是結合匯流排狀拓樸與星狀拓樸兩種拓樸所形成的,包含星狀拓樸的工作站群組再連結至匯流排狀拓樸的纜線。樹狀拓樸允許在現有的網路中擴展,校園網路可依需求使用樹狀拓樸。

Advantages of a Tree Topology 樹狀拓樸的優點

  • Point-to-point wiring for individual segments.
  • 獨立的區段可以點對點連接
  • Supported by several hardware and software venders.
  • 許多軟體及硬體廠商都支援

Disadvantages of a Tree Topology 樹狀拓樸的缺點

  • Overall length of each segment is limited by the type of cabling used.
  • 每一個網段所使用的纜線長度會因為使用的線材不同而有限制
  • If the backbone line breaks, the entire segment goes down.
  • 主幹網路如果損壞,整段網路都無法連線
  • More difficult to configure and wire than other topologies.
  • 相較於其他網路拓樸比較難設定及配線
