A processor-based method for securing files through a persistent signature includes selecting file contents; selecting a file header associated with the file contents; selecting a private key, a certificate identifier and a hash algorithm identifier; creating an encrypted hash of the file contents and file header using the hash algorithm and private key; and creating a persistent, independent signature for the file contents and file header that identifies the certificate identifier, hash algorithm identifier, and the encrypted hash value.

A conference collaboration system has a server connected to a network and configured to generate a page view requested by a client device over the network and provide dynamic content associated with the requested page view for display on the device; and a database configured to store the dynamic content, update the dynamic content in response to commands from the server, and provide the dynamic content to the server in response to requests from the server, wherein the dynamic content is associated with a plurality of services, each shown in a page view, and the dynamic content and the services are associated with a conference. The server can determine an authorization level of a user interacting with the client device and provide a page view and dynamic content in response to the authorization level, and the dynamic content is updated or created in response to or for actions during the conference.

Methods and apparatus that enable a transport protocol executing on a first computer system to be utilized by applications executing on a second computer system which is directly interconnected and closely coupled to the first computer system. An interconnection couples an input/output (I/O) subsystem of the first computer system to an I/O subsystem of the second computer system and provides a path over which data can be transmitted between the first and second computer systems independent of a network interface card, and an interconnection messaging system executing on the first and second computer systems provides general purpose transport interfaces between said first and second computer systems. A distributed transport communications manager executing on the first and second computer systems controls use of the interconnection messaging system to establish a dialog through which the transport protocol of the first computer system may be used by an application executing on the second computer system in a manner which is transparent to the application. The transport protocol executing on the first computer system may be utilized by a plurality of networked computer systems including the second computer system, where the interconnection messaging system establishes dialogs through which the transport protocol of the first computer system may be used by applications executing on the networked computer systems. Conversely, applications executing on the second computer system may utilize transport protocols executing on a plurality of networked computer systems including the first computer system.

Distributed transport communications manager with messaging subsystem for high-speed communications between heterogeneous computer systems

Methods and apparatus that enable network applications executing on respective directly interconnected computer systems to communicate at high speed, with low latency, over the interconnection therebetween such that both systems may use their native mechanisms to communicate with each other without change in those mechanisms, rather than over conventional network communication paths such as Ethernet. Communication between applications in co-resident, closely coupled processing environments is provided by replacing the conventional TCP transport layer and the conventional IP network layer with a reliable messaging subsystem (&ldquo;MSS&rdquo;) for data transfers between the closely coupled systems which provides an interface which is independent of the communication protocol of the interconnect and a virtual transport layer (&ldquo;VTL&rdquo;) which simulates a known transport layer protocol, such as TCP/IP, to the network applications. MSS is a system interconnect independent messaging transport which presents to its users many different delivery and notification mechanisms for the transfer of both control and data information between different heterogeneous environments, while VTL uses the MSS connection to provide a consistent, interconnect independent interface to the session layer.

Virtual transport layer interface and messaging subsystem for high-speed communications between heterogeneous computer systems

A high speed data communications method and system is provided whereby multiple groups of software interfaces are used to link a Distributed Systems Services Unit to a Network Provider which connects to an Input/Output Interface Module which relates to external interfaces of a Network. The interfaces permit the capability of buffer sharing and lock pool sharing, in addition to improved Connection Library Element Interfaces which reduce the overhead that was previously required and further enables faster data transfer operations with reduced latency.

Multiple interface data communication system and method utilizing

An improved high-speed data communications system is provided having software functions which permit a Network Data Path Interface to work in conjunction with a Distributed System Service application and a Network Provider application for enhancing data transfers to a Input/Output module and Network Processor. The improved Network Data Path Interface functions involve transmitting data outward to Channel Adapters via the use of shared buffers which can be re-used after utilization, and also receiving data by the sharing of buffers between a Distributed System Service application software unit, a Network Provider unit, and the Network Data Path Interface, enabling data to be received by the Network Provider for transferral to the Distributed System Service application unit.
