隨著電子商務的發展以及網路經濟的起飛，越來越多的使用者除了使用網際網路（Internet）取得所需的資訊外，亦開始透過各式手持裝置進行多樣化的網路交易（如：Amazon/Yahoo!/ 淘寶網 線上購物、Apple iTunes/App Store 線上數位內容⋯等等）而獲取各形式之資訊、產品及服務。在使用者進行網路交易的過程中，若電子商務的服務因為伺服器軟硬體故障或網路連線問題而導致服務中斷，原可取得的訂單將隨之消失，亦無法取得消費者的信任。本研究以網路供餵技術為基礎，搭配代理人的使用設計出一套能夠應用在可攜式裝置上，並具有使用簡單、高度可用性、輕量化，可用以支援非同步式網路互動之電子商務容錯服務架構。採用此架構可以改善企業服務並提高電子商務網站的彈性及可用性，讓企業把握住每一個可能的交易機會。

With the continuous development of e-commerce and Internet economy, more
and more people not only obtain necessary information through the Internet but also adopt various portable devices to conduct online transactions (such as Amazon/Yahoo!/
Alibaba online shopping, Apple iTunes App Store, etc.) to acquire various information,
products, and services. However, if the service is interrupted due to any server or network
connectivity or availability problems while performing online transaction tasks, an
e-commerce website might lose business opportunities and even their customers’ trust.
The main purpose of this study is to utilize the Web Feed technology together with agent
technology to design simple, highly available, and light weight e-commerce fault tolerant
service architecture applicable in a multimodal pervasive environment for supporting
asynchronous Web interactions. This framework may be utilized to enhance enterprise
services and improve the flexibility and availability of e-commerce websites, thus retaining more business opportunities.
