互联网的各项基本协议都由IETF专门以RFC的形式进行标准化,从而保证互联网设备的互联互通,例如RFC791定义了IP协议,RFC793定义了TCP协议等。因此,人们往往认为RFC都是那些乏味的二进制编码和协议交互方式的定义。事实上,RFC的类型包括Standards(标准)、DraftStandards(草案标准)、ProposedStandards(提案标准)、Experimental(实验性的)、Informational(知识性的)、Historic(历史性的)以及EarlyRFCs(在IETF标准化之前早期的),其中知识性的RFC不乏充满各种趣味和互联网历史的内容。例如,IETF为了纪念著名的互联网先驱JonathanB.Postel,1998年10月17日由互联网之父VintonCerf(TCP/IP协议的发明人之一,国际地址与域名机构ICANN主席)专门撰写了RFC2468。鉴于JonPostel所创建的IANA在互联网发展史上的突出作用,RFC2468取题“追忆IANA”来表示对JonPostel的敬意。此外,JonPostel曾经工作过的地方ISI至今仍然维护着一个网站“Postel中心(”http://www.postel.org/)用以纪念JonPostel对互联网作出的卓越贡献。  相似文献   

Enhancing Web‐based Courses through a Mutual Aid Framework     

Dina J. Wilke PhD  Karen A. Randolph  Linda Vinton 《Journal of Teaching in Social Work》2013,33(1):18-31

Students taking a class together belong to a group where members typically develop a sense of connection to each other by engaging in mutual support and assistance through shared experiences and knowledge. Some have argued that the lack of face‐to‐face interaction precludes such processes and prevents the effective teaching of social work in an online environment. When online students were asked what they liked most and least about their classes, one‐third of the responses referred to ideas that reflected interactions among students and with faculty. These comments were evaluated in the context of Shulman's (1999 Shulman, L. 1999. The skills of helping individuals, families, groups and communities, Itasca, IL: Peacock.  [Google Scholar]) processes of mutual aid. This exploratory study suggests that despite a lack of face‐to‐face contact, mutual aid is relevant to online students and could be used to strategically enhance the delivery of course content in an online environment and facilitate a sense of connection among students.  相似文献
