摘要： The invention ensures that a single and consistent reply is made to ARP request in a system of connected IP networks. In each host, the first adapter A to become active is designated as being in an arbitrary first physical network (PNET1). For each subsequent adapter B to become active on a host, the host sends a packet over one of the adapters (A) of each network already known to the host with a hop count of one. If the packet is received over adapter B, it is known that adapters A and B are in the same physical network. If this occurs, adapter B is marked as being in the same network PNET1 as adapter A. If the packet is not received over adapter B then B is in a different physical network as A. In this event, adapter B is marked as being in a new network PNET2. When adapter A becomes inactive, if there are other active adapters in the physical network to which A belongs, then one of the remaining adapters B in that physical network is designated to have the responsibility for replying to ARP requests for A. A gratuitous ARP advertisement is transmitted into the network mapping IP-A with MAC-B. When adapter A again becomes active, adapter A will re-assume ownership of ARP replies for IP address A.

摘要： One system of a multisystem environment takes over log entries owned by another system of the environment. When a system owning entries on a primary log stream is inactive (or a sync point manager on the system is inactive), another system of the multisystem environment writes the log entries corresponding to the inactive system to other locations. The entries within the other locations are not owned by any system. Thus, the resource managers associated with those log entries are eligible for restarting on any system of the multisystem environment. However, all resource managers involved in a common set of transactions are to restart on the same system. The other resource managers can restart on another system. When one of the resource managers restarts on a system, the system takes back ownership of the entries associated with the common set of transactions.

摘要： A multisystem log stream of a multisystem environment is compressed. The oldest record needed for each system that can write or delete entries from the multisystem log stream is tracked, and that information is used in compression of the log stream. The block ids associated with those oldest records are maintained within a vector, and when the vector is updated, a determination is made as to whether the entry in the vector that it replaced previously contained the lowest block id in the vector. If so, all the records having block ids lower than the new lowest block id in the vector are deleted.

摘要： Improvements for the efficiency of data transfer within interconnected components of a virtual network, and in particular components of a single physical computing device are provided. The components exchange data as if they were communicating over an actual communications network using networking protocols. Data packets to be sent from one component to another are buffered by final destination address to improve efficiency of packet delivery.

摘要： Inbound packets received by a physical network adapter of a processing device are routed by evaluating an inbound frame to determine if an inbound frame destination MAC address is associated with the processing device and determining whether the inbound frame should be routed to a corresponding logical interface or to drop the inbound frame if the inbound frame destination MAC address is equal to a virtual MAC address supported by the processing device. If it is determined that the inbound frame should be routed to the corresponding logical interface, then any necessary layer 3 functions are performed and the inbound frame is routed to the corresponding logical interface, thereby combining both layer 2 and layer 3 routing into a single logical function.
