The present invention relates to a method and an architecture capable of efficiently providing a virtual desktop service. The service architecture for the virtual desktop service includes a connection broker for performing the management of virtual machines, a server monitoring function, and a protocol coordination function. A resource pool is configured to manage software resources that are transferred to a specific virtual machine in a streaming form at a predetermined time and that are executed on the specific virtual machine and to provide provision information about the managed software resources at the request of the connection broker, in order to provide an on-demand virtual desktop service. A virtual machine infrastructure is configured to support hardware resources, generate virtual machines in which the software of the user terminal is operated, and provide the virtual machines as virtual desktops.

A method and system for dynamic and adaptive deployment of in-process agents to virtual machine based applications which may run on remote hosts is provided. A bootstrap agent is injected into the application, using standardized interfaces provided by virtual machine based systems like Sun Microsystems' Java or Microsoft's .NET. Said bootstrap agent establishes a network connection to a management server which provides binaries representing in-process agents in bytecode or native code format. The bootstrap agent sends data identifying its runtime environment to the management server, which determines the matching in-process agent binaries for the runtime environment of the connected agent and sends the selected binaries to the bootstrap agent. The bootstrap agent receives the binaries and installs them to its hosting virtual machine, according to their format (bytecode or native code).

A mobile dual-stack node engages in IPv6 communication while roaming within an IPv4-only network. The node determines that it has moved and obtains a new IPv4 address. After determining that the visited network contains no IPv6-enabled components, the node communicates with a tunnel broker to obtain a care-of address and a tunnel to an IPv6 connect agent (e.g., a tunnel server). If the obtained care-of address differs from the care-of address that the node had been using prior to the move, the node sends MIPv6 binding updates to its home agent and corresponding peers. The node can optimize the handoff when it has obtained a different care-of address by sending a binding update to the connect agent comprising the previous care-of address and the current care-of address. When the connect agent receives a packet destined for the previous care-of address, it forwards the packet to the current care-of address.

A method and apparatus for accessing a computer resource, wherein, during a first access sequence, the computer resource receives credentials of a user from a device the user is using to access the computer resource, encrypts the credentials using at least a first credentials key stores the encrypted credentials, communicates the first credentials key to a connection broker or to the device, and purges the first credentials key. The computer resource, during a subsequent access sequence, receives the first credentials key, decrypts the encrypted credentials using the first credentials key, and purges the first credentials key. The computer resource authenticates the user using the credentials and purges the credentials after the user is authenticated and enables the device to access the computer resource following the authentication of the user.

This invention relates to a method for remote monitor or maintenance and a device for realizing it, in which, a remote monitor or maintenance working station is connected with an agent connected with an object needing remote monitor or maintenance via network, and the agent first of all monitors the communication state of the object and then transmits the monitor result to the working station to decide if it needs to access the object, after the agent sets up a virtual channel for the connection requirement of the station, it manages the channel safely by setting a timer with fixed time interval and sets up a transparent transmission path between the station and the object.

A mobile IPv6 dual-stack node engages in IPv6 communication while roaming within an IPv4-only network, for example using ISATAP. First, the node determines that it has moved and obtains a new IPv4 address. After determining that the visited network contains no IPv6-enabled components, the node uses in IPv6 connect agent to engage in IPv6 communication. The node configures its care-of address using the IPv6 connect agent's routing information and the node's newly-obtained IPv4 address. In one embodiment, the node and the connect agent optimize the handoff when the node has moved but still uses the same connect agent. The node sends a binding update to the connect agent comprising the node's old care-of address and the node's new care-of address. When the connect agent receives a packet destined for the node's previous care-of address, it forwards the packet to the node's current care-of address, thereby reducing packet loss.

The invention relates to a distributed transaction processing method based on connection pool management. The distributed transaction processing method based on connection pool management comprises the steps that a connection pool is established on a proxy server; when the proxy server receives a first service request, sent by an application server, for transaction processing, persistent connection is established between the proxy server and a relevant database server, the service request is sent by the proxy server to each database server to be processed through the persistent connection, and all following service requests belonging to the transaction processing are sent to each database server to be processed through the established persistent connection; when the service request sent by the application server is the request for ending of the transaction processing or is not a transaction request, the proxy server withdraws the persistent connection established between the application server and each database server. By the adoption of the distributed transaction processing method based on connection pool management, the consistency and the integrity of transaction processing data are guaranteed, the isolation level of transactions is guaranteed, the promotion function on a high-concurrency data service is achieved, and the data consistency of high-concurrency access is guaranteed.

The invention belongs to the technical field of software development, and particular discloses an access drive and a data access method of a proxy database.
