目前,市场上至少有一打“push”产品。这一拥挤的“push”产品市场迫使分销商不断创新,以便在市场上保持微弱的优势。毫无疑问,当IE 4.0和Constellation在今年晚些时候发布后,这一市场将由微软和Netscape公司主宰。最有前景的创新有可能使一些较好的“push”产品发生改变,使其从有限的、基于web的文档发布系统变为羽翼丰满的智能代理软件。与其它一些试图解决信息过载问题的智能代理不同,“push”产品以其更为全面的解决方案鹤立于该类产品之群。以简洁著称的代理软件通常用于监视某一数据源是否发生改变,当发生改变时则以某种方式提醒用户。当然,现在的大多数“push”产品都是这样。 At present, there is at least one dozen “push” products on the market. This crowded “push” product market forces distributors to innovate so as to maintain a slight advantage in the market. There is no doubt that when IE 4.0 and Constellation are released later this year, this market will be dominated by Microsoft and Netscape. The most promising innovations are likely to change some of the better “push” products, from a limited web-based document publishing system to a full-fledged intelligent agent software. Unlike other intelligent agents that try to solve the problem of information overload, “push” products stand out from the group of products with their more comprehensive solutions. Proxy software, known for its simplicity, is typically used to monitor whether a data source has changed, and to alert the user in some way when a change occurs. Of course, most current “push” products are like this.
