摘要:
A communication system, which facilitates distribution of electronic communications for a user account, includes an emergency auto-reply agent that scans each received communication addressed to the user account for a particular communication sent from at least one emergency address specified for the user account separate from the address of the user account. Responsive to the communication system detecting the particular communication sent from one of the emergency addresses, the emergency auto-reply agent parses the content of the particular communication to detect whether the particular communication comprises a required password. Responsive to detecting the required password within the content of the particular communication, the emergency auto-reply agent directs the communication system to compose and send auto-reply communications from the user account in reply to received communications addressed to the user account.

The reassembly timer in a TCP/IP receiver is dynamically set to avoid data corruption on fast networks caused by IP identification wrap-around. A sender generates IP packets with a special option specifying a reassembly time for fragments based on the subnet of the destination or on the calculated round-trip time of the connection. A receiver sets the reassembly timer to the reassembly time specified in the option. A sender can generate IP packets with an alternative option setting a time stamp for the generated packet. A receiver calculates a traversal time based on the difference between the arrival time of the fragment and this time stamp, and sets the reassembly timer based on this traversal time. A receiver can independently set the reassembly timer to a first reassembly time set by the user for fast networks or to a second reassembly timer set by the user for slow networks based on whether the receiver and sender are on the same subnet.

A system, method, and program product is provided that requests, by a first computer system, a new network session with a second computer system. The new network session request occurs after a previous network session between the two systems and the new network session request includes a new sequence number that is different from a previous sequence number that was used during the previous network session. The first computer system receives an acknowledgement from the second computer system that references the previous sequence number instead of the new sequence number. In response to receiving the acknowledgement at the first computer system that references the previous sequence number, the first computer system modifies the new sequence number by setting it to a value that is higher than the previous sequence number, and the first computer system re-requests the new network session using the modified new sequence number.

A method for virtual segmentation off-load in a logically partitioned data processing system is provided. A data transmission protocol stack formats a data message for segmentation off-load to form a virtual segmentation off-load package. The size of the data message is larger than a size of a maximum transmission unit. A partition manager firmware copies the virtual segmentation off-load package from a first logical partition to a virtual Ethernet adapter associated with a second logical partition. The virtual segmentation off-load package is copied without performing a segmentation operation on the data message associated with the virtual segmentation off-load package.

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.

Illustrative embodiments provide a computer implemented method, a data processing system and a computer program product for locating contact information in a mobile phone network within a social network. In one embodiment, the computer implemented method permits reciprocal access between a first user's contact information and a second user's contact information by a first user device and a second user device, and permitting reciprocal access between the second user's contact information and a third user's contact information by the second user device and a third user device. The computer implemented method receives a request from the third user device to contact the first user device, wherein the first user contact information is unknown to the third user and issues a search on the mobile phone network, from the third user device, for the first user contact information. The first user contact information is located at the second user device in the social network, and the first user contact information is returned to the third user device.

A host enables any adapter of multiple adapters of the host to concurrently support any VIPA of the multiple VIPAs assigned to the host. Responsive to a failure of at least one particular adapter from among the multiple adapters, the host triggers the remaining, functioning adapters to broadcast a separate hardware address update for each VIPA over the network, such that for a failover in the host supporting the multiple VIPAs the host directs at least one other host accessible via the network to address any new packets for the multiple VIPAs to one of the separate hardware addresses of one of the remaining adapters.
摘要:
A technique for facilitating identification of a matching search term in one or more images includes selecting at least a portion of an image and creating search enriched metadata for a document that includes the image. The search enriched metadata includes a text portion that provides one or more search terms that are associated with the selected portion of the image and a location portion that provides a location of the selected portion of the image.
摘要:
The present invention provides receiving and transmitting devices for providing fragmentation at a transport level along a transmission path. The transmitting device comprises an interface and a control unit coupled to the interface. The control unit is adapted to negotiate a packet size with a remote device. The control unit is also adapted to transmit a data packet of up to the negotiated size. The control unit is further adapted to receive acknowledgments from the remote device associated with one or more fragments, fragmented at the transport-level, of the transmitted data packet. The receiving device comprises an interface and a control unit coupled to the interface. The control unit is adapted to receive two or more fragments of a data packet transmitted by a remote device. The control unit is also adapted to transmit one or more acknowledgments to the remote device based on the received fragments.
摘要:
The present invention provides a method and apparatus for providing fragmentation at a transport level along a transmission path. The method comprises receiving a data packet from a first remote device for transmission to a second remote device, wherein the data packet includes a transport-level protocol packet encapsulated in a network-level protocol packet and determining if a size of the received data packet is greater than a maximum transmission unit (MTU) value. The method further comprises performing fragmentation of the data packet at a transport-level protocol into two or more fragments in response to determining that the size of the received data packet is greater than the MTU value and transmitting one or more of the fragments to the second remote device.
