  • Publication number: 20140365564
    Abstract: A technique for providing information via a data network is disclosed. A first server transmits an identifier to a client, where the identifier is mappable to a uniform resource locator (URL) associated with content stored on a second server. The client transmits the identifier to a second server. The second server maps the identifier to its associated URL, retrieves the content associated with the URL, and transmits the content to the client. Various types of mappings are disclosed, including encryption and predetermined mappings.

  • Patent number: 8856281
    Abstract: A content delivery system includes a cache server, a domain name server, and a redirector. The domain name server is configured to receive a request for a cache server address, and provide an IPv6 anycast address. The redirector is configured to receive a content request addressed to the IPv6 anycast address from a client system, receive load information from the cache server, and determine if the cache server is available. The redirector is further configured to forward the content request to the cache server when the cache server is available. The cache server is configured to receive the content request forwarded from the redirectors, send a response to the content request to a client system, the response including an IPv6 unicast address of the cache server as a source address, an IPv6 unicast address of the client system as a destination address, and the IPv6 anycast address as a home address, and provide the content to the requestor.

  • Patent number: 8813213
    Abstract: An application provisioning device may be used to manage a profile of a host and provide data corresponding to a selected application for installation at a host. A reverse firewall may use the profile of the host to determine whether to allow or block particular network communication from an application running on the host. An indication of a selected application may be received at the application provisioning device. Configuration information may also be received at the application provisioning device. The application provisioning server may request an update to the profile of a host and transmit such a request. The profile may be updated to reflect the configuration information and/or information of the selected application. Data corresponding to the selected application may be updated and transmitted to a host computer, where it may be installed. Therefore, the installed application running on the host may operate without being prematurely blocked by the reverse firewall.

  • Publication number: 20140228040
    Abstract: Power and resource efficiency of a mobile network device are increased. In one aspect, a Tail Optimization Protocol (TOP) enables cooperation between a mobile device and an associated radio access network to eliminate idle periods (e.g., tails) when possible. Various systems and methods described herein can leverage the ability of applications and/or their associated connections to accurately predict a long tail time, from which a mobile device can notify an associated cellular network on such an imminent tail in order to allow the cellular network to immediately release tail resources. Various other aspects provided herein realize TOP via fast dormancy and/or other similar notification mechanisms, which enable a handset or other device to notify a cellular network for immediate resource release.

  • Publication number: 20140206344
    Abstract: A method, computer readable medium and apparatus for correlating measures of wireless traffic are disclosed. For example, the method obtains the wireless traffic, and processes the wireless traffic by a plurality of probe servers, where each of the plurality of probe servers generates a plurality of feeds, wherein the plurality of feeds comprises a data feed and a control feed. The method correlates the plurality of feeds from the plurality of probe servers, where the data feed and the control feed of each of the plurality of probe servers are correlated with at least one other probe server of the plurality of probe servers to provide a correlated control plane and a correlated data plane, and extracts at least partial path information of a flow from the correlated control plane. The method then correlates performance information from the correlated data plane for the flow.

  • Patent number: 8776224
    Abstract: According to an aspect of this invention, a method to detect phishing URLs involves: creating a whitelist of URLs using a first regular expression; creating a blacklist of URLs using a second regular expression; comparing a URL to the whitelist; and if the URL is not on the whitelist, comparing the URL to the blacklist. False negatives and positives may be avoided by classifying Internet domain names for the target organization as “legitimate”. This classification leaves a filtered set of URLs with unknown domain names which may be more closely examined to detect a potential phishing URL. Valid domain names may be classified without end-user participation.

  • Patent number: 8750109
    Abstract: A packet trace is received. Inter-arrival times between the multiple packets in the packet trace are determined. An inter-arrival time in the inter-arrival times that is greater than a threshold is identified. An order number of the inter-arrival time is identified. A determination is made as to whether a size of each of at least a portion of the multiple packets is equal to a maximum segment size. When a determination is made that the size of each of at least a portion of the multiple packets is equal to the maximum segment size, a size of the ICW as a product of the order number and the maximum segment size is returned.
