A method for backing up a client data set on a computer by generating a manifest of the client data set and storing the manifest on a remote server along with a server data set corresponding to the client data set; taking a snapshot of the server manifest and data set; and comparing the manifest to the remote server data set and synchronizing the client dataset if a difference is detected.

The invention relates to a method for a communication node with a plurality of network interfaces. Configured on the communication node is a virtual interface, which is accessible from the applications able to be executed on the communication node. A configuration module generates an identifier assigned to the communication node. The identifier is stored in an identifier table. The configuration module checks the communication node for available network interfaces and sets up a network interface table with the available network interfaces. At least one IP address of an available network interface is stored in the identifier table in a way assigned to the identifier, and a connection module connects at least one of the available network interfaces to the virtual interface.

Methods, apparatuses and systems directed to improving the efficiency of bandwidth allocation schemes by adapting to slow-start mechanisms associated with network communications protocols, such as the TCP/IP protocol suite. In one implementation, the present invention scales down the initial target rate assigned to a data flow to a fraction of an initial estimate of the effective rate capacity of the communications path between two hosts. As packets are received, the target rate is gradually increased, eventually up to the detected rate capacity of the communications path. Implementations of the present invention improve the efficiency of bandwidth allocation by reducing the over-allocation of bandwidth to data flows during the slow-start phase, leaving more bandwidth available to other data flows.

The present invention is directed generally to an intelligent endpoint or communication device that can collect available bandwidth-related information metrics and/or perform call admission control functions. The present invention is further directed to an architecture comprising a switch or media server in communication with a plurality of subscriber communication devices in which the subscriber communication devices act as network nodes to collect available bandwidth-related information.

A telecommunications system includes a Public Land Mobile Network for providing wireless service to users and a wireless local area network functioning outside the said PLMN as a separate PLMN. An inter-PLMN backbone interfaces the WLAN to the PLMN, and an interworking function is coupled to the WLAN to provide seamless interactions between the PLMN and the WLAN to increase available service bandwidth provided for users of the PLMN.

A first router is configured for monitoring prescribed attributes of an active path connected to the first router, and supplying an update message to a second router, according to a prescribed routing protocol such as Enhanced Interior Gateway Routing Protocol (EIGRP), that specifies a detected change by the first router in at least one of the prescribed attributes of the connected active path. Hence, the second router, in response to receiving the update message, can update an internal topology table based on the detected change in the active path connected to the first router, and selectively adjust an internal routing table based on the detected change relative to queuing policies for prescribed data flows.

A method for the seamless switching of a wireless device between wireless wide area networks (WWANs) and wireless local area networks (WLANs) includes automatically detecting the available WWANs and WLANs, selecting one of the available networks for use by the wireless device, and connecting the wireless device to the selected network. The method also includes maintaining the network connection by monitoring the connection and, upon determining that the connection has been lost, selecting a another available network for use and connecting the wireless device the other network. Additionally, the method communicates information about the availability networks and connection status to a user of the wireless device, which allows the user to manually switch the wireless device connection from the automatically selected available network to another available network. Further, a wireless device implements the above described method.

A server computer at a first storage sub-system of a distributed storage system receives from a client a first client request for an object. If the object is not present in the first storage sub-system, the server computer identifies a second storage sub-system of the distributed storage system as having a replica of the requested object, the requested object including content and metadata. The server computer submits an object replication request for the requested object to the second storage sub-system and independently receives the content and metadata of the requested object from the second storage sub-system. The server computer generates a new replica of the object at the first storage sub-system using the received metadata and content and returns the metadata of the new replica of the object to the client.

An apparatus comprising one or more nodes. The apparatus may be configured to transport one or more packets within a frame. The one or more nodes may be configured to add and/or drop at least one of the one or more packet from the frame.

A memory system is provided that performs error correction at a memory device level that is transparent to a memory channel. The memory system comprises a memory hub device integrated in the memory module and a set of memory devices coupled to the memory hub device. The memory hub device comprises first error correction logic provided in write logic integrated in the memory hub device. The memory hub device comprises second error correction logic provided in read logic integrated in the memory hub device. The first error correction logic and the second error correction logic performs error correction operations on data transferred between a link interface and the set of memory devices. The memory hub device transmits and receives data via a memory channel between the external memory controller and the link interface without any error correction code.

Multiple data transfer requests can be merged and transmitted as a single packet on a packetized bus such as a PCI Express (PCI-E) bus. In one embodiment, requests are combined if they are directed to contiguous address ranges in the same target device. An opportunistic merging procedure is advantageously used that merges a first request with a later request if the first request and the later request are mergeable and are received within a holdoff period that is dynamically determined based on a level of bus activity; otherwise, requests can be transmitted without merging.

A bandwidth efficient routing protocol for wireless ad-hoc networks. This protocol can be used in ad-hoc networks because it considerably reduces control overhead, thus increasing available bandwidth and conserving power at mobile stations. It also gives very good results in terms of the throughput seen by the user. The protocol is a table-driven distance-vector routing protocol that uses the same constraints used in on-demand routing protocols, i.e., paths are used as long as they are valid and updates are only sent when a path becomes invalid. The paths used by neighbors are maintained and this allows the design of a distance-vector protocol with non-optimum routing and event-driven updates, resulting in reduced control overhead.

The memory hub device transmits and receives data via a memory channel between the external memory controller and the link interface without any error correction code.

A Dynamically Reconfigurable Dynamic Wireless Network for connecting a local area network (“LAN”) to wireless Mobile Stations. Backbone Access Points (“Backbone APs”) are physically connected to the LAN. Levels of Wireless Access Points (“Wireless APs”) are daisy-chained together and connected to the Backbone AP, providing an extended area of network coverage. Mobile stations are connected to either Backbone APs or Wireless APs. Dynamic Reconfiguration prevents single point failures. Each AP contains a router, Address Resolution Protocol (“ARP”) cache, and Distributed Routing Table (“DR Table”). The DR Table maintains the Media Access Control (“MAC”) address and the Internet Protocol (“IP”) address of each AP below it in the Distributed Routing Tree. Additionally, each DR Table also maintains the IP address for the device each AP is connected. The Distributed Routing Tree is dynamically reconfigured to minimize transmission hops or to maximize signal strength between Mobile Stations and the LAN.
