A method and apparatus for storing and delivering documents on the internet

Techniques are described for configuring intercommunications between multiple computing nodes, such as multiple virtual machine nodes hosted on one or more physical computing machines or systems. In some situations, virtual networks may be established and maintained for groups of computing nodes, such as those operated by or on behalf of various users. Such virtual networks may be established in some situations by automatically configuring various communication manager modules to associate communications from a computing node belonging to a virtual network with one or more networking identifiers associated with the virtual network, such that other communication manager modules may appropriately forward or otherwise process such communications.

Configuring intercommunications between computing nodes

In a packet data transmission and reception system a media access control (MAC) message is broadcast by a base station to a plurality of mobile stations. The MAC message contains packet data transmission scheduling information which allows the base station to preemptively control mobile station access to traffic channels in order to maximize the efficiency of packet data transmissions and allow scheduling consideration including priority access, quality of service and maximum bytes per transfer. The MAC message consists of a control frame structure which comprises scheduling parameters including MAC IDs fields, activity fields, and a field representing the number of free traffic channels in a cell. These parameters enable multiple mobile stations to share, in a time multiplexed fashion, traffic channels for packet data transmission on CDMA based mobile communication systems.

System and method for service based social network

Techniques are described for providing capabilities to dynamically migrate computing nodes between two or more computer networks while the computer networks are in use, such as to dynamically and incrementally migrate an entire originating first computer network to a destination second computer network at a remote location. For example, the first computer network may include one or more physically connected computer networks, while the second computer network may be a virtual computer network at a remote geographical location (e.g., under control of a network-accessible service available to remote users). The provided capabilities may further include facilitating the ongoing operations of the originating first computer network while a subset of the first computer network computing nodes have been migrated to the remote destination second computer network, such as by forwarding communications between the first and second computer networks in a manner that is transparent to the various computing nodes.

Dynamically migrating computer networks

In a packet switched communications system an incoming real-time packet is imbedded after the next block of data of the non-real-time packet being transmitted. This object is accomplished by transmitting each packet along with at least a 1-byte trailer which is used to indicate the packet type, whether the current block of non real time data is preempted or whether the current block of non real time data is resumed.

Method and apparatus for transmission of high priority traffic on low speed communication links

Method for transmitting high-priority packets in an IP transmission network based upon the Internet Protocol (IP) wherein low-priority packets or fragments of packets are transmitted between a sender and a receiver and at least a high-priority packet can be transmitted from the sender to the receiver by pre-emption of a low-priority packet or a fragment of packet. The method comprises in the sender, the steps of determining whether a low-priority packet or fragment of packet is being transmitted from the sender to the receiver when a high-priority packet has to be transmitted, setting to 1 a reserved bit within the IP header of the high-priority packet used as a pre-emption indicator if a low-priority packet or fragment of packet is currently transmitted, transmitting the high-priority packet with the pre-emption indicator set to 1 from the sender to the receiver, and resuming the transmission of the low-priority packet or fragment of packet at the end of transmission of the high-priority packet.

An apparatus and method for multicasting messages stored in data buffers of a data storage. Each message is composed of data stored in a plurality of the data buffers. Each data buffer is controlled and mapped to a unique direct control block (DCB) which stores information characterizing the data buffer. By chaining the DCBs variable length, messages can be generated. Indirect control blocks (ICB) stores information characterizing the data or messages duplicated and points to a DCB. A field in the DCB carries a count representing the number of times the message is to be duplicated.

Method and device of multicasting data in a communications system

Certain exemplary embodiments provide a method for converting data packets based upon IPv4 protocol into data packets based upon IPv6 protocol, said method comprising converting any data packet based upon the IPv4 protocol into a data packet based upon the IPv6 protocol before transmitting it to an IP switched network using information provided by an external server, and converting any data packet based upon the IPv6 protocol provided by said IP switched network into a data packet based upon the IPv4 protocol before transmitting it to a first or second workstation.

System for converting data based upon IPv4 into data based upon IPv6 to be transmitted over an IP switched network

An arbitration method and device for a data processing system wherein N units share a common resource, to allocate the shared resource to a given unit selected from a number of units requesting access thereto. An age value is assigned to each unit and corresponds to the age of the request that will be made by the unit. During an arbitration cycle, a unit whose request will be serviced, if the shared resource becomes available, is selected, this unit being the one whose request has an age value corresponding to the oldest request. Then, the age value associated with each unit is updated when the resource is available, the age of the selected unit assuming a value corresponding to that of the most recent request, the ages of the units not selected that correspond to requests more recent than the one made by the selected unit being increased by a given quantity, and the ages of the units not selected that correspond to requests older than the one made by the selected unit remaining unchanged.
