Abstract

We consider the mobility of personal online identifiers. People change the identifiers through which they are reachable online as they change jobs or residences or Internet service providers. This kind of personal mobility makes reaching people online error-prone. As people move, they do not always know who or what has cached their now obsolete identifiers so as to inform them of the move. Use of these old identifiers can cause delivery failure of important messages, or worse, may cause delivery of messages to unintended recipients. For example, a sensitive email message sent to my now obsolete work address at a former place of employment may reach my unfriendly former boss instead of me. We describe HINTS, a historic name-trail service. This service provides a persistent way to name willing participants online using today's transient online identifiers. HINTS accomplishes this by connecting together the names a person uses along with the times during which those names were valid for that person. A correspondent who wishes to reach a mobile person can use an obsolete online name for that person, qualified with a time at which the online name was successfully used; HINTS resolves this historic name to a current valid online identifier for the intended recipient, if that recipient has chosen to leave a name trail in HINTS.

历史悠久的命名路线服务

我们考虑个人在线标识符的移动性。当人们更换工作、住所或互联网服务提供商时，他们就会改变在线访问的标识符。这种个人的移动性使得在网上联系人们容易出错。当人们移动时，他们并不总是知道是谁或什么缓存了他们现在已经过时的标识符，以便通知他们移动。使用这些旧标识符可能导致重要消息的传递失败，或者更糟的是，可能导致将消息传递给意外的收件人。例如，发送到我以前工作地点的旧工作地址的敏感邮件可能会到达我不友好的前老板那里，而不是我。我们描述了HINTS，一个历史悠久的命名路径服务。该服务提供了一种持久的方式，使用今天的临时在线标识符在线命名有意愿的参与者。提示通过将一个人使用的名字以及这些名字对这个人有效的时间联系在一起来实现这一点。通讯员如果希望联系到一个移动的人，可以使用一个过时的在线名称，并限定该在线名称成功使用的时间;如果收件人选择在HINTS中留下名称踪迹，则提示将此历史名称解析为预期收件人的当前有效在线标识符。
