摘要： A method, system and/or computer program steer internet protocol (IP) packet fragments that are components of a series of IP packet fragments. A switch receives an IP packet fragment. In response to determining that the fragment is not a lead packet fragment in a series of IP packet fragments that make up an original IP packet, the IP packet fragment is pushed onto a data stack. The switch then receives an IP packet fragment which is determined to be the lead packet fragment in a series of IP packet fragments. The IP 5-tuple from the lead packet fragment is parsed to steer all fragments in the series to a destination port.

摘要： A method, system and/or computer program product route IP packet flows. An Ethernet switch is coupled to a load balancing control engine, which contains load balancing logic that is logically isolated from the Ethernet switch. The Ethernet switch, which routes IP packet flows to servers, receives an IP packet flow. The load balancing control engine determines if the servers are balanced in their workloads. In response to the load balancing control engine determining that the servers are balanced, the Ethernet switch routes the IP packet flow to the servers without the Ethernet switch directly receiving any feedback from the servers regarding their workloads. In response to the load balancing control engine determining that the servers are unbalanced, the load balancing control engine instructs the Ethernet switch to redirect the IP packet flow to a server that is relatively less busy than other servers.

摘要： A method, switch, and/or computer program product routes IP packet flows. An Ethernet switch receives an IP packet flow. Each of the packets in the IP packet flow has a header that contains a same 5-tuple. A load balancing control engine determines whether servers in a group of servers are balanced in their utilization according to 5-tuple redirection rules contained in the load balancing control engine. In response to the load balancing control engine determining, according to the 5-tuple redirection rules, that the servers are balanced, the Ethernet switch routes the IP packet flow to the servers. In response to the load balancing control engine determining that the servers are unbalanced, the load balancing control engine instructs the Ethernet switch to redirect the IP packet flow to a server that is relatively less busy than other servers.

摘要： A method, system, and/or computer program product steers Internet Protocol (IP) packet fragments. A switch receives a first IP packet fragment that contains a 3-tuple in its header. In response to determining that the first IP packet fragment is not a lead packet fragment in the series of IP packet fragments, the first IP packet fragment is pushed onto a data stack. The switch subsequently receives a second IP packet fragment that contains a 5-tuple, which includes the 3-tuple from the first IP packet fragment plus a source port and destination port used by the second IP packet fragment. The 3-tuple is mapped to the 5-tuple in a fragmentation table, thus enabling both the first IP packet fragment and the second IP packet fragment to be steered to the destination port to which the second IP packet fragment is being sent.

摘要： A computer-implemented method, apparatus, and computer usable program code are disclosed for migrating a virtual adapter from a source physical adapter to a destination physical adapter in a data processing system where multiple host computer systems share multiple adapters and communicate with those adapters through a PCI switched-fabric bus. The virtual adapter is first caused to stop processing transactions. All in-flight transactions that are associated with the virtual adapter are then captured. The configuration information that defines the virtual adapter is moved from the source physical adapter to the destination physical adapter. The in-flight transactions are then restored to their original locations on the destination virtual adapter. The virtual adapter is then restarted on the destination physical adapter such that the virtual adapter begins processing transactions.

摘要： Method and system for address routing in a distributed computing system, such as a distributed computing system that uses PCI Express protocol to communicate over an I/O fabric. A destination identifier is provided to identify a physical or virtual host or end point. When a physical or virtual host or end point receives a PCI data packet it compares a list of source identifiers with destination identifiers to determine if a source identifier included in the transaction packet is associated with a destination identifier included in the transaction packet to determine if the transaction packet has a valid association. If the transaction packet has a valid association, it is routed to the target device. The present invention enables each host that attaches to PCI bridges or switches and shares a set of common PCI devices to have its own PCI 64-bit address space and enables the routing of PCI transaction packets between multiple hosts and adapters, through a PCI switched-fabric bus using a destination identifier.

摘要： A method, mechanism and computer usable medium is provided for distributing I/O fabric errors to the appropriate root nodes in a multi-root environment. The case where the I/O fabric is attached to more than one root node and where each root can potentially share with the other roots the I/O adapter (IOA) resources which are attached to the I/O is addressed. Additionally, a method, mechanism and computer usable medium is provided by which errors detected in an I/O fabric may be routed to all root nodes which may be affected by the error, while not being reported to the root nodes that will not be affected by those errors. In particular, distributed computing system which uses the PCI Express protocol to communicate over the I/O fabric is addressed.

摘要： A system in which a networked device automatically evaluates hacker attack notification information and, based thereon, selects and executes responses to the attack. The notification may include information such as the address of the infected system, identification of the specific worm, and a list of vulnerable applications and operating systems. The evaluation is based on factors including criticality and vulnerability of applications running on the system and connectivity of the device. A variety of automatic responses can be selected, including notification of network administration, shutdown of the device or services running on the device, updating and activation of anti-virus software, and selective handling of data sent from the address of the suspect network device. The selection of responses can occur automatically based on rules input during setup or by intervention of network administration.

摘要： A computer-implemented method, apparatus, and computer program product are disclosed in a data processing environment that includes host computer systems that are coupled to adapters utilizing a switched fabric for routing packets between the host computer systems and the adapters. A unique destination identifier is assigned to one of the host computer systems. A portion of a standard format packet destination address is selected. Within a particular packet, the portion is set equal to the unique identifier that is assigned to the host computer system. The particular packet is then routed through the fabric to the host computer system using the unique destination identifier.

摘要： System and method for managing routing of data in a distributed computing system, such as a distributed computing system that uses PCI Express protocol to communicate over an I/O fabric. A physical tree that is indicative of a physical configuration of the distributed computing system is determined, and a virtual tree is created from the physical tree. The virtual tree is then modified to change an association between at least one source device and at least one target device in the virtual tree. A validation mechanism validates the changed association between the at least one source device and the at least one target device to enable routing of data from the at least one source device to the at least one target device.
