A method, system, and program are provided for managing a response to an email by a hidden email recipient. A hidden recipient manager detects a request to respond to an electronic communication by a hidden recipient of that electronic communication from among a plurality of recipients of the electronic communication. The hidden recipient detects whether the request to respond is addressed to at least one recipient other than a sender of the electronic communication. If the request to respond is addressed to at least one recipient other than a sender of the electronic communication, then the hidden recipient manager warns the hidden recipient that the request to respond is addressed to at least one recipient who is unaware of the recipient of the electronic communication by the hidden recipient.

A method, apparatus, and computer instructions are provided for propagating a physical device's link status to one or more virtual devices associated with the physical device. Link status information about the physical device indicating a failure in the physical device is identified using partition management firmware. The link status information about the physical device is propagated by partition management firmware to one or more virtual devices associated with the physical device. The logical partition using the virtual device use the virtual device link status to determine if a physical link to an outside network is down, and take appropriate remedial actions as may be necessary.

A method, system and apparatus for maintaining a two-byte identification field of IP headers when a Gigabit Ethernet is in use are provided. Since the IP identification field is of two bytes, there is a limited number of identification numbers that may be used. Due to the high data transfer rate of the Gigabit Ethernet, this number may be reached within one second. Hence, there may be a possibility that two or more packets may have the same identification number while in transit. In a representative embodiment, one identification number is used for packets that may not be fragmented; thus, freeing the rest of the numbers for packets that may be fragmented.

Administering acknowledgment messages (‘ACKs’) in the Transmission Control Protocol (“TCP”) that include establishing a TCP connection between a sender and a receiver, receiving by the receiver one or more TCP messages from the sender, and transmitting an ACK from the receiver to the sender only when necessary. Administering ACKs in TCP according to embodiments of the present invention may include measuring by the sender a round trip time for transmission of TCP messages between the sender and the receiver and transmitting to the receiver a data-bearing TCP message once per round trip time. Establishing a TCP connection between a sender and a receiver may include measuring by the receiver a round trip time for transmission of TCP messages between the receiver and the sender. Transmitting an ACK only when necessary may include transmitting an ACK when no message from the sender arrives at the receiver for two round trip times.

Methods, systems, and products are provided for tunneling IPv6 packets. Embodiments include receiving, by an origin IPv6 border router from an origin IPv6 host, an IPv6 packet having an IPv6 destination address; receiving, by an origin IPv6 border router from an origin IPv6 host, an IPv4 address for a destination IPv6 border router retrieved from a data structure associating IPv6 destination addresses with IPv4 addresses for destination IPv6 border routers; encapsulating, by the origin IPv6 border router, the IPv6 packet in an IPv4 packet; and sending the encapsulated packet to a destination IPv6 border router at the IPv4 address. In many embodiments, encapsulating, by the origin IPv6 border router, the IPv6 packet in an IPv4 packet is carried out by adding an IPv4 header to the IPv6 packet.

A method and apparatus is provided for enabling a telephone caller to generate a brief message for transmission to an intended call recipient, as part of the initial procedure of setting up a phone call between the caller and recipient. The message is sent and displayed or otherwise made available to the recipient before the recipient is required to answer the call. The message could comprise a sequence of alphanumeric characters that conveyed an abbreviated message, or otherwise indicates the purpose to the call to the recipient or provides other information. Respective characters could be transmitted as corresponding sequences of binary tones sent to the call recipient between telephone rings.

A method, system, and computer program product for delivering data, received from a network on a network adapter to a pre-assigned port, to a storage buffer assigned to an application are disclosed. An application designates an application-specific buffer within a local data processing system for buffering data communicated with the application. The local data processing system reports to a network interface of the local data processing system a memory address of the designated application-specific buffer, and the data processing system designates a port on which to receive packets addressed to the memory address. The data processing system then sends a port registration message to the local network interface, enabling the network interface to compare the port number of incoming traffic to a registered port number and route incoming traffic from a remote data processing system directly to the designated application-specific buffers in the event of a match. In one embodiment, the present invention includes receiving in the network interface a packet addressed to the specific port and delivering data from the packet to said application-specific buffer.

A method and system for providing subgroup conversation during a teleconference enables side conversations during a virtual meeting. A passcode is used by parties to join the subgroup conversation, so that privacy of the subgroup is maintained. Alternatively, an administrator may set up subgroups and either join or invite members, who may toggle between the main teleconference and a subgroup teleconference using a standardized user input. The system may be implemented in any telephone network and across telephone networks such as public switched telephone networks (PSTNs), wireless networks, voice over Internet protocol networks and/or private branch exchanges (PBXs).
摘要:
A method, apparatus, and computer instructions for negotiating a protocol for a conversation in which data packets are transmitted. Responsive to establishment of a link aggregation with an endpoint for the conversation, an algorithm for processing the data packets in the conversation is selected to form a preferred algorithm. A request is sent to the endpoint. This request indicates the preferred algorithm for processing the data packets in the conversation. A reply to the request is received from the endpoint. A determination is made as to whether a convergence has occurred. The data packets in the conversation are processed using the preferred algorithm in response to a determination that the convergence has occurred.
摘要:
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.
