摘要： A method is disclosed for routing data packets in a wireless network, preferably a Bluetoothnull network. The method includes estimating a link bandwidth of at least one network node, calculating a connectivity metric based on the estimated link bandwidth, distributing information concerning the calculated connectivity metric and, using the calculated connectivity metric, determining a route having a maximum link bandwidth and a minimum traffic load. Preferably, estimating uses a model of a Bluetooth network medium access control MAC algorithm. The connectivity metric is defined as a ratio of a maximum link bandwidth to the estimated link bandwidth, where the maximum link bandwidth is the link bandwidth between a Master node and a Slave node when there is only one Slave node connected to the Master node (i.e., when there is one Slave node in the piconet with the Master node).

摘要： A method for packet-oriented transmission of speech, audio, video and/or useful data between an internal and a public data network by means of a pre-reservation of NAT addresses. A pre-NAT address is allocated to the IP address of an internal computer by an NAT address server. The relevant allocation data set is available in a NAT host 200 which acts as a gateway between the internal and the public data network; whereby single addresses (pre-NAT addresses) are provided for transparent use of the data packet in the internal and public network when the information on the origin or destination in an IP Header or in the protocol data, in addition to the information on origin or destination in said header, is modified.

摘要： A method of setting up a delegated connection for processing by an offload unit is described. The method comprises establishing a TCP connection and determining whether or not to delegate the TCP connection for processing by the offload unit, producing a delegated connection, and setting up the delegated connection by creating a delegated connection table entry. When frames are received on the delegated connection by the offload unit, the offload unit determines if user buffers are available. When user buffers are available, the offload unit uploads payload data to the user buffers. When user buffers are not available, the offload unit uploads a portion of the payload data to a buffer allocated in Operating System memory space.

摘要： The invention concerns a method for transmitting packets in a network comprising at least a first sub-network and a second sub-network connected through a transparent communication link, said link comprising at least a first interface device connected to the first sub-network and a second interface device connected to the second sub-network. The method comprises the steps of: attributing a first set of addresses to the interface devices on the communication link; attributing a second set of addresses to nodes connected to the sub-networks, the attribution of the second set being done independently from the attribution of the first set; checking whether there appears a conflict between an address of the first set and an address of the second set, and in the affirmative: changing the conflicting address of the first set to a non conflicting address. The invention also concerns a device for implementing the method as well as a method for detecting and transmitting packets to be transmitted over the link.

摘要： A method and apparatus are provided for implementing predefined actions based upon packet classification and lookup results in a communications network processor. A plurality of sets of rules is defined. Each rule set includes at least one rule and each rule has a set of masked compares for comparing results of hits and misses of table lookups. Each masked compare set has an associated field for selecting an action. The action defines a set of one or more commands and each command defines a processing operation. One rule set is identified based upon the packet classification result for a received packet. When one of the rules is identified having a match of the masked compares, then the action of associated with the identified rule is selected. Otherwise a default action is provided responsive to no rule of the identified rule set having a match of the masked compares.

摘要： An originating network, such as an originating wireless communication network, selectively performs multimedia content transcoding of outgoing multimedia messages as a function of the corresponding destination network addresses. More particular, in an exemplary embodiment, the originating network includes or has access to one or more databases that are accessed to determine whether transcoding is desired. Such information may comprise a listing of destination addresses, e.g., email addresses, or particular domain identifiers, for which transcoding is desired. Moreover, such information can indicate whether default or specific transcoding formats should be used. With this approach, the originating network can transcode all, or selected multimedia content, e.g., audio, video, etc., into one or more coding formats that known or expected to be compatible with the coding formats used by the targeted destination networks.
