An apparent network interface permits one processor such as a processor embedded within a larger processing system (an embedded processor) to communicate to a host processor or other processors and devices on the network to which the embedded processor is attached, using standard network communication mechanisms/protocols such as TCP/IP, NFS, FTP, HTTP, etc. The web server protocol HTTP is particularly useful because it permits the embedded computer to publish a user interface for remote monitoring and remote control using a standard web browser application. The invention provides the host computer with an apparent network interface that appears to be a standard network device, such as an Ethernet interface card. This apparent interface communicates directly with the embedded processor, which appears to be a device on this apparent network. Significant cost savings and performance enhancements are realized by implementing the communication directly over the host computer's peripheral bus rather than using standard network hardware such as Ethernet hardware.

Some embodiments of the invention provide a robust scaling-out of network functionality by providing a software layer, called the network hypervisor, that sits between the network forwarding functions (i.e., the forwarding plane) and the network control interfaces (i.e., the control plane). The network hypervisor of some embodiments provides a logical abstraction of the network's forwarding functionality, so that network operators make their control decisions in terms of this abstraction, independent of the details of the underlying networking hardware. The network hypervisor of some embodiments may then “compile” commands placed against this abstraction into configurations of the underlying hardware. Accordingly, in some embodiments, there are two design challenges: (1) the choice of the network abstraction, and (2) the technology needed to compile the logical “abstract” controls into low-level configurations.

A method and system for interconnecting peripherals, processor nodes, and hardware devices to a data network to produce a network bus providing OS functionality for managing hardware devices connected to the network bus involves defining a network bus driver at each of the processor nodes that couples hardware device drivers to a network hardware abstraction layer of the processor node. The network bus can be constructed to account for the hot-swappable nature of the hardware devices using a device monitoring function, and plug and play functionality for adding and, removing device driver instances. The network bus can be used to provide a distributed processing system by defining a shared memory space at each processor node. Distributed memory pages are provided with bus-network-wide unique memory addresses, and a distributed memory manager is added to ensure consistency of the distributed memory pages, and to provide a library of functions for user mode applications.

An external processor for a network access system having a programmable access device includes a service controller that provides at least one service for network traffic, a message processor that processes network messages for service processing by the service controller, and a programmable access device controller that programs the programmable access device in response to service controller processing. It is advantageous for the external processor to include primary and secondary service controllers for a particular service so that, if the primary service controller fails, the secondary service controller can provide the particular service for message received from the programmable access device. In preferred embodiments, the service controller further includes a reporting processor that provides an interface through which reporting messages received from the programmable access device can be communicated to the service controller and a signaling controller that transmits signals to configure network hardware to establish requested network connections. The external processor preferably further supports a service policy interface through which the service controller can request policy decisions from a possibly remote policy server.

The decision to discard or forward a packet is made by a flow control mechanism, upstream from the forwarding engine in the node of a communication network. The forwarding engine includes a switch with mechanism to detect congestion in the switch and return a binary signal B indicating congestion or no congestion. The flow control mechanism uses B and other network related information to generate a probability transmission table against which received packets are tested to determine proactively whether a packet is to be discarded or forwarded.

In a data network congestion control in a virtualized environment is enforced in packet flows to and from virtual machines in a host. A hypervisor and network interface hardware in the host are trusted components. Enforcement comprises estimating congestion states in the data network attributable to respective packet flows, recognizing a new packet that belongs to one of the data packet flows, and using one or more of the trusted components and to make a determination based on the congestion states that the new packet belongs to a congestion-producing packet flow. A congestion-control policy is applied by one or more of the trusted components to the new packet responsively to the determination.

A computer graphics processing system includes an integrated graphics and network hardware device having a PCI Express interface logic unit, a graphics processor unit, a graphics memory, a compression unit and a network interface unit, all connected together on a PCI Express adapter card using one or more dedicated communication interfaces so that data traffic for graphics processing and network communication need not be routed over a peripheral interface circuit which has a communications bandwidth that must be shared with other system components.

The system comprises an information manager including routing information for the network. The configuration manager operates to establish a connection across each subnet on the route by sending requests to element managers to program the subnet elements.

A computer network system includes a client-server architecture, where the client transmits SCSI commands over a network using TCP/IP to a server to request input and output operations for a physical storage device that is communicatively coupled to a storage device. The client perceives the storage device to be a local disk drive, even though the storage device is located on the target side of a network. The system includes a client-side disk-based cache.

When a piece of network equipment is determined to be stolen or missing, a hardware tracing tool mounted within the network detects the distinctive hardware fingerprints of the missing hardware within Internet traffic and extracts the device's IP address to trace the location of the missing equipment. As Internet messages or data packets cross through servers containing the tracing tool, the data packets are decompiled to retrieve unique identifier indicia (hardware fingerprints), such as a computer's MAC address, for example. The extracted fingerprints are then compared with fingerprints stored in a database of missing hardware using a hashing or mapping function, and the server system is alerted to a match. The IP address of the device transmitting the matching indicia is then extracted to determine the location of the missing or stolen network hardware. In this way, a method of tracing missing network hardware is provided that does not increase the cost of network equipment or unnecessarily effect network bandwidth.
