Abstract: Virtual machines in a network may be isolated by encrypting transmissions between the virtual machines with keys possessed only by an intended recipient. Within a network, the virtual machines may be logically organized into a number of community-of-interest (COI) groups. Each COI may use an encryption key to secure communications within the COI, such that only other virtual machines in the COI may decrypt the message. Virtual machines may be automatically provisioned with configuration information, such as the encryption keys, when the virtual machine is started. The provisioning information may be created based on a template stored on a configuration server.

Each COI may use an encryption key to secure communications within the COI, such that only other virtual machines in the COI may decrypt the message. Virtual machines may further be isolated through a virtual gateway assigned to handle all communications between a virtual machine and a device outside of the virtual machine's COI. The virtual gateway may be a separate virtual machine for handling decrypting and encrypting messages for transmission between virtual machines and other devices.

Abstract: Dynamic licensing improves the utilization of licenses available within a computer network. License sinks, such as gateways, within a computer network may request licenses from a license source. The license source may be provisioned with a number of licenses from a secure fob plugged into the license source. If the license source has the number of licenses requested from the license sink, the license source may assign the licenses to the license sink. After a certain period of time, the license sink may renew the licenses or let the licenses return to the license source to be assigned to another license sink. The license requests may be passed through the network, including through a proxy and/or a relay, to a license server provisioned with licenses. Dynamic licensing software may execute as a service on each of the license sources and license sinks to pass dynamic licensing messages between devices.

Abstract: A distributed computer system comprises an enterprise server and a network server. The distributed computer system utilizes a distributed transmission control protocol (TCP) to establish an off-loaded dialog through the network server. If the off-loaded dialog is interrupted by, e.g., failure of the hosting network server, dialog recovery is performed to move the off-loaded dialog.

Abstract: Intelligent NIC optimizations includes system and methods for Token Table Posting, use of a Master Completion Queue, Notification Request Area (NRA) associated with completion queues, preferably in the Network Interface Card (NIC) for providing notification of request completions, and what we call Lazy Memory Deregistration which allows non-critical memory deregistration processing to occur during non-busy times. These intelligent NIC optimizations which can be applied outside the scope of VIA (e.g. iWARP and the like), but also support VIA.

Abstract: Optimization of the Virtual Interface Architecture (VIA) on Multiprocessor Servers using Physically Independent Consolidated NICs (Network Interface Cards) allows for improved throughput, increased resiliency and transparent fail-over; and also by hiding the actual NICs involved in particular data transactions, enables operations with substantially unmodified applications software.

Abstract: Methods and apparatus to diagnose software including diagnostic gathering instructions are disclosed. The software is diagnosed by storing diagnostic information to a plurality of individual trace buffers responsive to the diagnostic gathering instructions, consolidating the diagnostic information from the plurality of individual trace buffers to a consolidated trace buffer, and presenting at least a portion of the consolidated diagnostic information.

Abstract: 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.

Abstract: 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 (“MSS”) 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 (“VTL”) which simulates a known transport layer protocol, such as TCP/IP, to the network applications.
