| dc.description.abstract | IPv6為國際網際網路標準組織IETF所訂定的新一代網際網路通信協定（目前Internet所使用之通信協定為IPv4），除了有128位元充足位址空間（IPv4位址空間僅有32位元），亦增添了許多新的優點，如自動網路芳鄰找尋（Neighbor Discovery）與自動定址（Auto-configuration）機制，簡化使用者IP位址設定，且增加了訊務等級（Traffic Class）和訊流標籤（Flow Label），用以支援品質保證（QoS）與即時訊務之需求，同時在協定的本身也定義了IP安全機制等。同時亦考量無線行動機制之需求（Mobile IPv6），並且考慮實際的狀況，例如:人們身上攜帶資訊裝置搭乘飛機、火車、船等移動式網路（Mobile Network）時，將如何與網際網路做連線。也就是移動式網路移動到外地網路時，要告知原屬代理器（Home Agent）及通訊節點（Correspondent Node）目前移動式網路所在的轉送位址（Care-of Address），這樣才可以將封包傳送給移動式網路內的節點。
在本論文中，移動式網路依假設的模擬架構，在Mobility Driven跟Data Driven 情況下，分別使用單一播送（Unicast）以及群體播送（Multicast）作連結更新訊息（Binding Update）時，所佔用網路頻寬之分析。並且可以由模擬結果得知，在什麼條件下（Mt、Mm、Tc、CN number），使用群體播送作連結更新訊息會比使用單一播送好，也就訊號量（Signal）比較少。 | zh_TW |
| dc.description.abstract | IPv6 is a new generation of Internet Protocol (the one so far used is IPv4) defined by Internet Engineering Task Forcing (IETF). Besides 128-bits sufficient addressing spacing, it also adds in many new advantages such as： Neighbor Discovery and Addressing Auto-Configuration to simplify the IP address configuration of users. Even it supports Traffic Class and Flow Label mechanisms to sustain Quality of Service and Real-time traffic on demand. At the same time, the protocol entity itself defines the IP security mechanism and considers the wireless mobility situation. For example, when carrying mobile device to get on airplane, train or ship, how to connect to Internet. That is, when Mobile Network moves to the Foreign Network, it shall inform the Home Agent and Correspond Node the present Care-of-Address, and then the packets can be forwarded to the mobile nodes in the Mobile Network.
In this thesis, Mobile Network in according to simulation architecture in assumption uses Unicast and Multicast to analysis occupied network bandwidth in Binding Update operation, separately in different conditions: Mobility Driven and Data Driven. We can see in the simulation results in which conditions(Mt、Mm、Tc、CN number) it is better to do Binding Update with Multicast than with Unicast(more less signals). | en_US |
