Abstract: A method, system, and computer program product for caching data in a cellular network is provided. Information from a cellular network regarding location, speed, direction of travel, and bandwidth for a user can be used to determine how much data should be cached for the user. More specifically, the time period for how long a user will be in a cell of a cellular network can be calculated using information received from the cellular network. The calculated time period can be used to calculate how much data will be used by a user for the calculated time period with only the amount of data needed for the time period being cached.

Abstract: A method of operating a network message interceptor for enforcing an authentication policy for communication over a network between first and second network endpoints, the interceptor being in communication with the network and external to the first and second endpoints, the network including transport layer security, the method comprising the steps of: intercepting a handshake message transmitted over the network between the first and second endpoints; extracting a certificate for an authenticating one of the endpoints from the handshake message; determining a validity status of the certificate for confirming an identity of the authenticating endpoint; and preventing communication between the first and second endpoints based on a negatively determined validity status of the certificate.

Abstract: The present disclosure relates generally to the field of identifying network flows (e.g., IP flows) under network address translation.

Abstract: Mobile network services are performed in a mobile data network in a way that is transparent to most of the existing equipment in the mobile data network. The mobile data network includes a radio access network and a core network. A first service mechanism in the radio access network breaks out data coming from a basestation, and performs one or more mobile network services based on the broken out data. A second service mechanism in the core network performs one or more mobile network services based on the network traffic remaining after the first service mechanism performs its breakout. An optional third service mechanism coupled to the core network provides one or more mobile network services in the mobile data network. An overlay network allows the first, second and third service mechanisms to communicate with each other. The overlay network is preferably a private virtual network.

Abstract: A mobile data network includes a radio access network and a core network. A first service mechanism in the radio access network breaks out data coming from a basestation. When data is broken out by the first service mechanism, the data is delivered at the edge, which means the true activity of the channel is not visible to the core network. The reduction of data in the core network due to serving data at the edge risks causing a switch from a high-speed channel to a low-speed channel by the mechanism in the core network that monitors and assigns channel speeds. In order to maintain the high-speed channel, the on-going data rate for a subscriber session is monitored and channel maintenance traffic is injected towards and from the radio network controller (in both directions). The amount of channel maintenance traffic depends on thresholds that determine a desired data rate.

Abstract: A store routing system for guiding a shopper in a store comprises a storage storing a store product map comprising location information for products available at the store. The system also comprises an analytics engine for identifying one or more recommended products for the shopper based on a set of one or more sought products. The system also comprises a route calculator for calculating a route through the store to a location of each of the sought products based on the store product map and for including a waypoint in the route corresponding to a location of each of the one or more recommended products.

Abstract: A method of operating a network message interceptor for enforcing a security policy for communication over a network between first and second network endpoints, the interceptor being in communication with the network and external to the first and second endpoints, the network including transport layer security, and the security policy identifying at least one valid security standards for communication over the network, the method comprising the steps of: intercepting a handshake message transmitted over the network between the first and second endpoints; extracting from the handshake message an identification of a security standard selected for the communication between the first and second endpoints; determining a validity status of the identified security standard based on the security policy; and preventing communication between the first and second endpoints based on a negatively determined validity status of the identified security standard.

Abstract: Methods and apparatus are provided for recovering from packet loss in an end-to-end network connection having at least one wireless segment. A packet on a wireless segment of an end-to-end network connection is processed by determining whether the packet comprises one or more of a lost packet and a malformed packet; and generating a modified packet for an application associated with the packet to replace one or more of the lost packet and the malformed packet if the application is substantially tolerant to one or more of lost and malformed data. The modified packet comprises, for example, a non-original packet and/or a corrected packet. Link layer information or information from a deep packet inspection can be used to determine whether the packet comprises a lost packet or a malformed packet.
