多重定址技術 讓一個節點可以透過多條線路同時連到網際網路. 流控制傳輸通訊協定是一個支援多重定址技術的傳輸層通訊協定.使得一個多重定址的節點可以建立多重路徑到他的連線端點. 多重路徑資料傳輸擴充了流控制傳輸通訊協定使其可以透過多條路徑同時傳輸新資料. 然而,仍然連線仍然被限制在兩個節點之間.在本篇論文之中,一個新的通訊協定 "跨節點多路徑傳輸之分散式串流控制傳輸協定"被提出, 以達到在一個流控制傳輸通訊連線之中,在多節點之間建立多條連線同時進行傳輸之目的.除了流控制傳輸通訊協定與多重路徑資料傳輸原先即具備的功能外,我們新設計了 "新增子連線" 與 "刪除子連線" . 一個流控制傳輸通訊連線可以經由上述兩種方法在多個節點之間隨時動態新增刪除子路徑. 同時一些議題也在本篇論之中被提出. 我們提出了一個修正 TSN 指派的方法與新的 ACK 產生演算法來解決傳輸上延生的問題. 模擬的結果顯示 "跨節點多路徑傳輸之分散式串流控制傳輸協定" 可以動態的在多節點之間新增刪除子路徑以同時使用多重路徑傳輸資料.因此"跨節點多路徑傳輸之分散式串流控制傳輸協定"是一個對應用程式設計如檔案傳輸與點對點傳輸有益的.

“Multihominig” technique enables a host/site to connect to the Internet through more than
one link. Stream Control Transmission Protocol (SCTP), which is a transport layer protocol
for multihoming, allows a multihomed host to establish multiple paths towards its endpoint.
Concurrent Multi-path Transfer (CMT)-SCTP extends the base SCTP to allow an SCTP host
to transmit new data to its endpoint through multiple paths at the same time. However, in
CMT-SCTP, an association (SCTP’s term for “connection”) is still limited exactly between
two end hosts. In this thesis, a new SCTP extension protocol, namely “D-SCTP”, is proposed
to achieve concurrent multi-path transmission over multiple end hosts within a single
SCTP association. In addition to the existing features provided by SCTP and CMT-SCTP,
an Add Path Procedure and a Delete Path Procedure are designed. Paths destined to different
hosts can thus be dynamically added and deleted in an existing association at any time.
Furthermore, issues related to D-SCTP are investigated in this thesis. A TSN assignment
adjustment mechanism and a new SACK generation algorithm are also devised to tackle the
side-effects caused by concurrent multi-path transmission across multiple end hosts. The
simulation results in this thesis also show that, the mechanisms provided by D-SCTP can
dynamically add/delete hosts to transfer data concurrently. Thus, D-SCTP is very adequate
for the development of applications such as FTP services and P2P data transfer, to improve
the efficiency of data transmission.
