A messaging system receives a registration from a first microservice for one or more event types to publish, and the registration includes an event report policy. The messaging system receives a first event, and the first event is described by the event report policy. The first event is monitored as it is processed by a second microservice. An event report describing the results of the monitoring is delivered to the first microservice.

Host port information is pulled directly from the switch before zoning is performed and is organized by chassis as an assist for mapping and masking an entire chassis. A graphical user interface allows a user to select storage by chassis to map and to select servers by chassis to map. The user then applies that mapping such that all servers selected are mapped to all storage selected. The user may repeat this mapping for another set of storage and servers. In a mixed environment, an icon may be shown in the graphical user interface to represent the mix. When the LUN mapping/masking is done, the LUN mapping/masking may be provided to the SAN manager to perform zoning. The LUN mapping/masking defines which host ports see which storage ports.

An I/O module includes a switch module, a redundant array of independent disks (RAID) controller and a baseboard management controller (BMC). A first address for a first component of the plurality of components is received. The first address is provided by a user. The switch module is queried for additional addresses for additional components of the plurality of components. The switch module obtains the additional addresses for the additional components from a first persistent storage location associated with the switch module. The first and additional addresses for the first and additional components are stored in a second persistent storage location accessible by the BMC, the switch module, and the RAID controller. Synchronization of the first and additional addresses for the first and additional components in the second persistent location is controlled by the BMC.

A method, system and apparatus for improving data transfer rate over a network are provided. When a piece of data is to be transmitted to a target system, it is divided into a number of packets and a determination is made as to whether the number of packets exceeds a threshold number. If so, the packets are transferred in parallel over a plurality of network connections. The ideal network connections are TCP/IP connections. Thus, each packet has an IP header, which contains an IP identification field. An indicium is placed into the IP identification field for proper reconstruction of the data by the target system.

Apparatus and method of splitting a data stream over multiple transport control protocol/internet protocol (TCP/IP) connections

Provided are techniques for state information sharing. At least one of user information and browser information is stored in a first configuration file in a first file format associated with a first browser application. A change in at least one of the user information and the browser information in the first configuration file is recognized. The changed at least one of the user information and the browser information in the first file format is converted to a second file format associated with a second browser application. A second configuration file is updated with the changed at least one of the user information and the browser information in the second file format. In response to starting the second browser application, a user and browser state is set using the user information and the browser information in the second configuration file.

User/browser state information sharing between browser applications

A method, apparatus, and computer instructions for processing packets in a network layer. A packet is received for transmission in which the packet includes a destination address. A routing entry for the destination address is identified. A determination is made as to whether a flag indicating the packet is to be broadcast has been set in the routing entry. Header information is placed in the packet in which the header information indicates that the packet is a broadcast packet in response to the flag being set.

A method, system, and product are described for alleviating router congestion when the router is processing packets transmitted by computer systems having a congestion notification capability. The router marks packets transmitted between a first computer system and a second computer system when the first and second computer systems have the congestion notification capability. The marking indicates that the router is moderately congested. A marked packet is then received by the first computer system. The router then drops packets transmitted by the first computer system when the packets were transmitted subsequent to the receipt of the marked packet.

A method, apparatus, and computer instructions for processing a data packet in an interpartition virtual network in the logical partitioned data processing system. A state of a first flag and a state of a second flag is identified in the data packet, in response to receiving the data packet at a first partition in the interpartition virtual network from a second partition in the interpartition virtual network in the logical partitioned data processing system. A checksum is selectively verified for the data packet based on the state of the first flag and the state of the second flag.

A method, apparatus, and computer instructions for handling requests in a data processing system. A plurality of processes is provided to handle the requests. Each of the plurality of processes is assigned to handle requests from a subset of foreign ports within a plurality of foreign ports such that a set of foreign ports assigned to a process is unique with respect to other subsets of foreign ports within the plurality of foreign ports. A foreign port is identified in a request in response to receiving the request. The request is sent to a process assigned the subset of foreign ports having a match to the foreign port in the request, wherein the process handles the request.

The present invention provides a method and apparatus for discovering a path maximum transmission unit. The method comprises receiving a data packet from a first remote device for transmission to a second remote device and determining if a size of the received data packet is greater than a maximum transmission unit (MTU) value. In response to determining that the size of the received data packet is greater than the MTU value, the method further comprises transmitting a portion of the received data packet to the second remote device and transmitting a message to the first remote device indicating that the size of the received data packet exceeds the MTU value.

A system and method of reducing data corruption due to recycled Internet Protocol (IP) identification numbers are provided. When IP packets are being fragmented and the IP identification number of the packets is cycling through a specific group of numbers, the size of the first fragment of a packet is decremented each time the IP identification cycles through the numbers. Initially, the size of the first fragment of a packet will be set to a maximum number. This size will be decremented at each pass of the IP identification through the numbers until the size of the first fragment of a packet reaches a pre-defined minimum size. When that occurs, the size of the first fragment of a packet will again be set to the maximum number. By decrementing the size of the first fragment, fragment offset of the other fragments that make up the packet will be changing. This then reduces the likelihood of having two fragments having the same IP identification number be mistaken as being from the same packet.
