Systems and methods of processing network packets are described. These systems and methods provide improved packet processing results by logically and physically separating packet header processing functions from packet data processing functions. In this way, a network processing system may perform network handling operations and data processing operations substantially in parallel. One or more embodiments feature a network adapter for exchanging with a computer network information in the form of packets each including a packet header and packet data. The network adapter includes a packet parser configured to parse an information packet into a packet header and packet data and to direct the packet header to a first memory address for protocol processing and to direct packet data to a second memory address for data processing.

Processing network packets

A software architecture for the hot add and swap of adapters. The software architecture allows users to replace failed components, upgrade outdated components, and add new functionality, such as new network interfaces, disk interface adapters and storage, without impacting existing users. The software architecture supports the hot add and swap of off-the-shelf adapters, including those adapters that are programmable.

A method and apparatus for interfacing buses includes a system interface processor coupled to a first bus and including a command register accessible via a second bus. A request buffer and a response buffer are provided which are accessible via the second bus and coupled to the interface processor. The request buffer can be used to store information to be transmitted from the second bus to the first via the interface processor while the response buffer can be used to store information to be transmitted from the first bus to the second bus via the interface processor. The interface processor may include a status register to indicate the status of the interface controller. The interface controller may also include a command register to receive commands transmitted over the second bus.

Method for hot swapping a programmable adapter by using a programmable processor to selectively disabling and enabling power thereto upon receiving respective control signals

A method for displaying the slot number and Hardware Instance Number (HIN) of devices attached to a Peripheral Component Interface (PCI) bus is disclosed. The method determines the slot numbers and HINs for every device attached to the PCI bus. This information is displayed to the user. The method thus provides the user with a mechanism for determining the physical slot location of PCI devices in a computer system once the HIN for the PCI device is known.

Method for the hot swap of a mass storage adapter on a system including a statically loaded adapter driver

Method for the hot add of devices

A configuration management system and method for adding or replacing devices in a bus in a computer system. The configuration system creates and maintains a memory structure having bus and device configuration information. The system includes a configuration manager which creates a memory structure containing configuration information for a bus and devices located on the bus within the computer system in which it operates. When a device on the bus is replaced, the configuration manager retrieves the configuration information for the replacement device from the memory structure and uses that information to configure the replacement device. In another aspect of the invention, when a device is added on the bus in the computer system, the configuration manager retrieves selected configuration information for the added device from the memory structure and uses that information to configure the added device.

A software architecture for the hot add and swap of I,O compliant input/output platform and adapters. The software architecture allows users to replace failed components, upgrade outdated components, and add new functionality, such as new network interfaces, disk interface adapters and storage, without impacting existing users. The software architecture supports the hot add and swap of off-the-shelf adapters, including those adapters that are programmable.

A system is described for providing fault tolerance within a computer system. The system provides a method for allowing multiple network interface cards to reside within the same computer system. If the primary network interface card fails, a secondary network interface card automatically begins managing the network communications. In addition, a system that provides load-sharing of data transmissions between each network interface card installed in a server computer is described.
