Abstract: Systems and methods for combining streaming media content items for streaming to a client computer across a network are described. In one aspect, a server computer receives a request from a client computer for one or more content items. Responsive to receiving the request, the server computer identifies a data structure that refers to the one or more further content items. The server computer modifies the data structure to reference the requested content items. The server computer provides the content items referenced by the modified data structure to the requesting client computer for streaming media content to a user.

Abstract: A chat interface allowing a user to exchange haptic chat messages with other users in a chat session over a computer network. A chat interface can be displayed by a local computer and receives input data from a user of the local computer, such as text characters or speech input. The input data provides an outgoing chat message that can include sent force information. The outgoing chat message is sent to a remote computer that is connected to the local host computer via a computer network. The remote computer can display a chat interface and output a haptic sensation to a user of the remote computer based at least in part on the force information in the outgoing chat message. An incoming message from the remote computer can also be received at the chat interface, which may also include received force information. The incoming chat message is displayed on a display device to the user of the local computer.

Abstract: A system for permitting new, or enhanced, functionality to be transferred to an adaptable device. In a preferred embodiment, the permitted functionality is determined according to an accounting method associated with a user's account. This approach allows a user to contract for specific services, functionality, etc. regardless of changes over time such as changes to data formats, communication protocols, external devices or infrastructure, etc. In a preferred embodiment, the functionality is stored on a ubiquitous communications network such as the Internet. Functionality is transferred to different devices as digital information over the network. This allows hardware functionality to be licensed in many forms. For example, site licenses can be obtained for companies; hardware “trialware” can be provided to allow limited functionality for a limited time for lower-cost payments, etc.

Abstract: A system and method for mapping outbound communications (e.g., encapsulated Ethernet packets) from InfiniBand queue pairs (QP) and/or virtual lanes (VL) to ports through which they are to be transmitted to an external communication system. A memory is shared between the InfiniBand receive side and transmit side. A shared control structure facilitates management of a linked list for each queue pair. A linked list is composed of entries in the control structure; each entry stores a value identifying the next control entry in the list and a memory bucket associated with the entry. Each queue pair terminating has a head pointer identifying the first control entry and memory bucket, and a tail pointer identifying the last control entry and memory bucket of a linked list. When a communication is reassembled, pointers defining a sub-list comprising the communication are passed to a network transmit module.

Abstract: A method, system, apparatus, and computer program product are presented for management of a distributed data processing system. Resources within the distributed data processing system are dynamically discovered, and the discovered resources are adaptively monitored using the network management framework. A network or system administrator configures some mission critical endpoints with multiple network interface cards (NICs) and specifies mission critical endpoints, non-mission critical actions, etc. During status collection activities associated with network or system management activities, the categorization of an endpoint as a mission-critical or non-mission critical endpoint affects the manner in which the status collection activity is performed.

Abstract: Packets and packets fragments possibly received out of sequence are distributed into an expandable set of queues. For each particular packet or fragment, a queue within a set of queues is identified that does not contain a packet or packet fragment that is subsequent to the particular packet or fragment, and the particular packet or fragment is enqueued therein. If there is not such a queue available, a new queue is added to the set of queues. A data structure is typically updated for packet fragments to identify when all fragments have been received and the order of queues containing the packet fragments in order of their position within the reassembled packet. This ordered list of the queues is communicated to a reassembly mechanism to retrieve the packet fragments and to reassemble the packet. Resequencing of packets is similarly performed, and may be part of the reassembly process.

Abstract: Communication connection for peer-to-peer communication is established as follows.

Abstract: A method for safely adding nodes to a network provides safeguards to prevent adding nodes beyond a maximum number of nodes allowed in the network. In one aspect, if the node to be added exceeds the maximum number of nodes allowed, the connection between the node to be added and the network is quarantined. If the node to be added does not exceed the maximum number of nodes allowed, the connection is confirmed. In another aspect, an additional test is made to determine if the connection between the network and the node to be added creates a loop within the network. In the case of a detected loop, the connection between the network and the node to be added is quarantined. If the connection does not create a loop, it is confirmed.

Abstract: Systems for transmitting information from terminal systems (1) via access multiplexers (3) comprising virtual forwarder systems (5) to networks are made less complex by inserting at the terminal systems (1) virtual forwarder internet protocol addresses (35,64,66) into destination fields of internet protocol headers for heading the information and by inserting destination internet protocol addresses (36,37,38,65,67) into routing fields of the internet protocol headers. Both the terminal systems (1) and the access multiplexers (3) should be made capable of dealing with internet protocol headers of the internet protocol version-4 or the internet protocol version-6 or higher, which comprise a destination field and a routing field.

Abstract: A data compression program making a computer perform processing which enables compression of only highly compressible data. First, a transmitter-side device performs compression processing of a portion of data to be compressed. Next, the transmitter-side device compares volumes of the portion of the data before and after the compression processing, and determines whether or not the compression processing is effective. When the data to be compressed is uncompressed data, the volume of the portion of the data is reduced by the compression processing. On the other hand, when the data to be compressed is compressed data, the volume of the portion of the data is not reduced by the compression processing. Therefore, only when it is determined that the compression processing is effective, the transmitter-side device compresses the other portions of the data to be compressed.
