Abstract:
A method and system of coordination independent rate adaptation is disclosed. The method and system of coordination independent rate adaptation provides for deploying a rate adaptation subdomain into a packet network having no rate adaptation coordination among the network nodes. The method and system is particularly useful for incremental introduction of rate-adaptive devices in existing networks; combining the best properties of sleep-state exploitation and rate scaling techniques by defining a class of state-setting policies for rate adaptation schemes that enforce tight deterministic bounds on the extra delay that the schemes may cause to network traffic at every node where they are deployed.
Abstract:
The invention includes a method and apparatus for notification and delivery of messages to mobile users using a secure client associated with a user device. The secure client includes a power module, a communication module, a storage module, and an alert module. The power module powers the client device independent of a power state of the user device. The communication module receives a wake-up message and responsively triggers the secure client to switch from an inactive state to an active state without changing the power state of the user device, initiates a secure connection with a secure gateway in response to the wake-up message, and requests and receives a user message from a messaging application using the secure connection. The storage module stores the received message independent of the power state of the user device. The alert module activates an alert to indicate that the message is available.
Abstract:
A method of remotely treating malicious mobile terminals connected to a mobile communications network. In one embodiment, when a malicious mobile terminal is detected by the intrusion-detection services of the network, the network changes the subscriber profile associated with the mobile terminal to operate the latter in a quarantine mode. The packet-switched subsystem of the network then links the quarantined mobile terminal to a remediation manager. The remediation manager remotely treats the mobile terminal, e.g., to repair or reinstall any corrupted software, terminate any active malicious processes, delete or quarantine any malware, and restore the operating system, configuration, and/or memory of the mobile terminal to a clean operational state. After the treatment, the network reverts the subscriber profile back to the initial state and removes the mobile terminal from the quarantine.
Abstract:
Expediting the distribution of data files between a server and a set of clients. The present invention relates to client-server systems and, more particularly, to cache nodes in client-server systems. In a client-server arrangement, a source system transfers data files from the source system to a server cache node connected to the source system. The server cache node sends a list of data files cached in the server cache node to a client cache node. The client cache node sends a request to the server cache node for new data files cached in the server cache node, based on the list received from the server cache node. The server cache node sends the requested data files to the client cache node and the client cache node transfers the data files to a destination system.

The invention includes a method and apparatus for providing secure remote access to enterprise networks. An apparatus (104) includes a network interface module (202) adapted for maintaining a secure network connection (120) with a network device independent of a power state of a host computer associated with the apparatus, a storage module for storing information associated with the secure connection, and a processor (204) coupled to the network interface and the memory where the processor is adapted for automatically initiating the secure connection without user interaction.

Abstract:
A system and method of rate adaptation is disclosed for energy efficiency. The system and method of rate adaptation for energy efficiency provides for parsing a heterogeneous network into rate-adaptation domains that are fully isolated with respect to the control of their operating states. The system and method is particularly useful for creating the conditions for the incremental introduction of rate-adaptive devices in existing networks; combining the best properties of sleep-state exploitation and rate scaling techniques by defining a class of state-setting policies for rate adaptation schemes that enforce tight deterministic bounds on the extra delay that the schemes may cause to network traffic at every node where they are deployed.
Abstract:
A system for expediting the transfer of data files between end systems in packet networks is disclosed. The application relates to data file transfers between end systems across a packet network and, more particularly, to expediting data file transfers in networks. Data file transfers may be slowed by lack of simultaneous availability of a network path between the end systems and of operational capability at either end system. The problem is addressed by incorporating an add-on module in the network path between the end systems. Data files are transferred to the add-on module from a source end system when the latter is capable of operation and connected to the former. Further, data files are transferred from the add-on module to the destination end system when the latter is capable of operation and connected to the former. As a result, time involved in completing data file transfers is reduced.
