Patent number: 8873411Abstract: Method and apparatus for provisioning an e-mail service to a mobile terminal in an e-mail system that uses e-mail addresses comprising a domain part. The apparatus maintains a list of good setting parameter sets versus e-mail domain parts. It receives an e-mail address and user authentication information from a user and compares the domain part of the received address with domain parts in the list of good parameter sets. If a match is found, e-mail service is provisioned with the matching parameter set. If no match is found, the apparatus requests and receives further parameters from the user, including an e-mail server address, and provisions the e-mail service with the further parameters. If the provisioning with the further parameters is successful, the domain part and the further parameters are used to generate a new setting parameter set in the list of good setting parameter sets.Type: GrantFiled: January 12, 2012Date of Patent: October 28, 2014Assignee: Seven Networks, Inc.Inventors: Ari Backholm, Seppo Salorinne, Jussi Heinonen, Marko Ketonen, Lauri Vuornos

Patent number: 8867341Abstract: A switch device includes a packet-forwarding table for providing traffic management across servers in a server group. Each table entry maps a hash value to a server in the server group. A hash value is computed from data in one or more fields in the header of a received packet. The computed hash value is used as an index into the packet-forwarding table to access a table entry and to identify from the table entry the server in the server group to which the table entry maps the computed hash value. The switch device forwards the packet to the identified server. Implementing traffic management decisions in hardware enables packet switching at the line rate of the switch ports. In addition, the hardware-based traffic management performed by the switch device eliminates session tables and the memory to store them, enabling the switch device to handle an unlimited number of client connections.Type: GrantFiled: October 8, 2010Date of Patent: October 21, 2014Assignee: International Business Machines CorporationInventors: Bill Shao, Cynthia Ann Gabriel, Tienwei Chao

Patent number: 8817645Abstract: Estimation of available bandwidth on a network uses packet pairs and spatially filtering. Packet pairs are transmitted over the network. The dispersion of the packet pairs is used to generate samples of the available bandwidth, which are then classified into bins to generate a histogram. The bins can have uniform bin widths, and the histogram data can be aged so that older samples are given less weight in the estimation. The histogram data is then spatially filtered. Kernel density algorithms can be used to spatially filter the histogram data. The network available bandwidth is estimated using the spatially filtered histogram data. Alternatively, the spatially filtered histogram data can be temporally filtered before the available bandwidth is estimated.Type: GrantFiled: November 18, 2011Date of Patent: August 26, 2014Assignee: Microsoft CorporationInventors: Yong Rui, Andres Vega-Garcia
