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 virtual data center allocation architecture with bandwidth guarantees that provides for the creation of multiple virtual data centers from a single physical infrastructure. The virtual data center allocation is accomplished in three steps. First, clusters are created from the servers in the physical infrastructure. Second, a bipartite graph is built to map the virtual machines to the servers located in a particular cluster and finally a path is calculated between two virtual machines. The virtual data centers may be dynamically expanded or contracted based on changing bandwidth guarantees.

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： 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.

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： A hybrid Butterfly Cube (“BCube”) architecture is described herein. The BCube architecture is a server-centric network architectural design, and includes a plurality of servers. Each of the plurality of servers may have multiple network ports and serve not only as an end host, but also an intermediate relay node for other servers. The BCube architecture further includes a plurality of switches which are arranged in multiple levels. Each switch has a certain number of network ports for connecting to the servers. The BCube architecture provides multiple parallel paths between any two servers. A packet source routing protocol and a BCube source routing (BSR) protocol are used to determine which path is used for routing a packet between any two servers.

摘要： A middle layer network protocol enhancement, virtual connectivity (VC) makes the network attachment point changes of local and remote peers transparent to applications that use network services. A virtual connectivity module local to each peer translates communication connection parameters from apparent to real and vice versa, as well as sending and receiving secure connection updates directly to and from peers. Unlike Mobile IP, no routing infrastructure modifications are required. A subscribe-notify service provides connection update notifications when direct peer-to-peer connection updates are not possible, for example, when two communicating peers move simultaneously or when the moving peer is communicating with a peer behind network address translation (NAT). Methods for detecting these conditions are disclosed, as is a virtual connectivity protocol and virtual connectivity module architecture.

摘要： A method for detecting a spurious timeout in a TCP network which can be used to avoid unnecessarily triggering the TCP rate adaptation is disclosed. Upon detection of a timeout on a given packet, a shortened packet version of the possibly lost packet is retransmitted. The retransmitted packet is at least one byte shorter than the original packet. The node receiving this retransmitted packet will acknowledge the receipt of the packet as specified in the TCP protocol. The acknowledgment will contain the sequence number of the lowest byte the receiving node has not yet received. Because the retransmitted packet is shorter than the original packet, the sequence number of this as yet not received byte will be less than or equal to the last byte of the original packet if the original packet was not received indicating a valid timeout. If the sequence number in the acknowledgment is greater than the last byte of the original packet than the original packet was received correctly and the timeout was caused by a lost acknowledgment and is considered a spurious timeout. In the case of a spurious timeout the congestion control mechanisms in the TCP protocol need not be used.

摘要翻译： 公开了一种用于检测可以用于避免不必要地触发TCP速率适配的TCP网络中的虚假超时的方法。 在检测到给定分组上的超时时，重传可能丢失的分组的缩短的分组版本。 重传的分组比原始分组短至少一个字节。 接收该重发分组的节点将确认在TCP协议中指定的分组的接收。 确认将包含接收节点尚未接收的最低字节的序列号。 由于重传的分组比原始分组短，因此未接收到的字节的序列号将小于或等于原始分组的最后一个字节，如果未收到指示有效超时的原始分组。 如果确认中的序列号大于原始数据包的最后一个字节，而不是原始数据包被正确接收，并且超时是由丢失的确认引起的，并且被认为是虚假超时。 在虚假超时的情况下，不需要使用TCP协议中的拥塞控制机制。
