    Abstract: Access is obtained to call data records (or other data) for a plurality of mobile telephony users. The call data records (or other data) include location-time sequences. For each of the mobile telephony users, corresponding ones of the location-time sequences are segmented into trips; a home-work-school classification model is used to determine a home location and a work-school location, based on the trips; and a trip purpose classification model is used to assign each of the trips a purpose label, based at least on comparing at least one of a start location and an end location for each one of the trips to at least one of the home location and the work-school location determined using the home-work-school classification model. The trips are aggregated into purpose based origin-destination categories based at least on the purpose labels, time ranges of the location-time sequences, and the start and end locations.

    Abstract: In one embodiment, a method and an apparatus for failure-resilient forwarding of data over a computer network include introducing a marker into the data stream, e.g., at the sending node, and allowing, in turn, forwarding nodes and/or receivers to efficiently track data stream reception. The marker functions as a checkpoint for the data transport process, and is identified and indexed at each forwarding node and receiver. Each receiver saves the marker prior to delivering data to an application, thereby designating a point in the data stream at which all preceding data is confirmed to have been delivered to the application. Thus, if a forwarding node fails, the receiver may request stream data from an alternate forwarding node by specifying to the alternate forwarding node to provide data starting from the marker.

    Abstract: Several deterrence mechanisms suitable for content distribution networks (CDN) are provided. These include a hash-based request routing scheme and a site allocation scheme. The hash-based request routing scheme provides a way to distinguish legitimate requests from bogus requests. Using this mechanism, an attacker is required to generate O(n2)amount of traffic to victimize a CDN-hosted site when the site content is served from n CDN caches. Without these modifications, the attacker must generate only O(n) traffic to bring down the site. The site allocation scheme provides sufficient isolation among CDN-hosted Web sites to prevent an attack on one Web site from making other sites unavailable. Using an allocation strategy based on binary codes, it can be guaranteed that a successful attack on any individual Web site that disables its assigned servers, does not also bring down other Web sites hosted by the CDN.

    Abstract translation: 提供了适用于内容分发网络（CDN）的几种威慑机制。 这些包括基于散列的请求路由方案和站点分配方案。 基于散列的请求路由方案提供了一种区分合法请求与假请求的方法。 使用这种机制，当从n个CDN缓存提供站点内容时，攻击者需要生成O（n2）个流量来伤害CDN托管站点。 没有这些修改，攻击者必须只生成O（n）流量才能关闭该站点。 站点分配方案可以在CDN托管的网站之间提供足够的隔离，以防止一个网站的攻击使其他站点不可用。 使用基于二进制代码的分配策略，可以保证对任何单个网站的成功攻击禁用其分配的服务器，也不会导致其他由CDN托管的网站。
