摘要： Techniques are described for balancing traffic load for networks configured in multi-rooted tree topologies, in the presence of link failures. Maximum flows (through minimum cuts) are calculated for subgraphs that incorporate effective link capacities on links between source and destination nodes. Effective link capacities may be determined that take into account link failures, as well as sharing of current available link capacities by multiple nodes. Traffic is balanced while simultaneously fully utilizing available link capacities, even available link capacities on partially failed links (e.g., partially failed Link Aggregation Groups (LAGs)).

摘要： Large numbers of commodity servers in a data center may be inexpensively interconnected using low-cost commodity network switches, a first network port on each commodity server, a second network port on each commodity server, and a traffic-aware routing module executed on each commodity server. Connecting two or more commodity servers via the first network ports on each server to a commodity network switch forms a unit. Connecting two commodity servers in different units forms a group. Each unit has a direct connection via a second network port on a commodity server in the unit to another unit. Each group may have a direct connection via a second network port on a commodity server in the group to another group. Traffic-aware routing modules executed on each commodity server determine routing of data between servers and balance traffic across the first and second ports.
摘要翻译：数据中心中的大量商品服务器可以使用低成本商品网络交换机，每个商品服务器上的第一网络端口，每个商品服务器上的第二网络端口以及在每个商品上执行的流量感知路由模块来廉价互连服务器。通过每个服务器上的第一个网络端口将两个或多个商品服务器连接到商品网络交换机，形成一个单元。连接不同单位的两个商品服务器组成一个组。每个单元通过单元中商品服务器上的第二个网络端口直接连接到另一个单元。每个组可以通过组中的商品服务器上的第二网络端口直接连接到另一组。在每个商品服务器上执行的流量感知路由模块确定服务器之间的数据路由，并平衡第一和第二端口的流量。

摘要： A geographic location of a network device is determined using response delay times from internet servers used as landmarks. A coordination server provides to a client a list of area landmark servers (ALS) with known geographic locations. The client probes ALSs, measures response delays, and provides results to the coordination server. The coordination server then provides to the client a list of additional city landmark servers (CLS) within the area. The client probes the CLSs and provides results to the coordination server which then determines the geographic location of the client.

摘要： A network address mapping system is described. The network address mapping system can identify a set of Web pages, collects information from the Web pages indicating geographical locations ("geolocations"), and correlate the geolocations with the network addresses from which the identified Web pages are served. The collected information can be weighted based on various factors, such as its relative position in a Web page. The collected information can then be used to identify a geolocation. The network mapping system can deduce geolocations for portions of ranges of network addresses based on the score, and can infer geolocations for other portions based on the deduced geolocations. This mapping can then be stored in a database and provided as a geomapping service. The network address mapping system is able to map network addresses to geographical locations. Thereafter, when a user's client computing device accesses a Web server, the Web server can easily and accurately determine a geographical location by querying the database storing the mapping or a geomapping service.
摘要翻译：描述网络地址映射系统。网络地址映射系统可以识别一组网页，从网页收集指示地理位置（“地理位置”）的信息，并且将地理位置与从其中服务所识别的网页的网络地址相关联。收集到的信息可以根据各种因素进行加权，例如其在网页中的相对位置。收集到的信息可以用来识别地理位置。网络映射系统可以基于分数推断网络地址范围的部分范围的地理位置，并且可以基于推导出的地理定位来推断其他部分的地理位置。该映射然后可以存储在数据库中并作为地理服务提供。网络地址映射系统能够将网络地址映射到地理位置。此后，当用户的客户端计算装置访问Web服务器时，Web服务器可以通过查询存储映射或地理服务的数据库来容易且准确地确定地理位置。

摘要： A method and system for providing a multi-level interconnection network is provided. A multi-level interconnection network comprises basic cells that are aggregated into higher level cells at each level of the network. At the first level, the basic cells are aggregated into first level cells. Each first level cell is an aggregation of a number of basic cells that is one more than the number of devices in a basic cell. The basic cells of a first level cell are fully connected; that is, each basic cell has a first level link or connection to each other basic cell. In a first level cell, each device of a basic cell has a first level link to each other basic cell. The multi-level interconnection network has higher level cells that are aggregations of lower level cells in a similar manner.
