Abstract: A network node comprises an optical input, an optical output, a random-access queue and a processing system. It receives a data packet, at the optical input and determines whether to process it as a guaranteed-service packet or as a statistically-multiplexed packet. A guaranteed-service packet is output within a predetermined maximum time of receipt, optionally within a data container comprising container control information. A statistically-multiplexed packet is queued. The node determines a set of statistically-multiplexed packets that would fit a gap between two guaranteed-service packets; selects one of the packets; and outputs it between the two guaranteed-service packets.

The method continues by, when at least one of the target stations has a different protocol than the protocol of the source station, determining whether the wireless communication is a direct wireless communication or an indirect wireless communication. The method continues with the source station transmitting a frame to an access point, wherein the frame is formatted in accordance with the protocol of the source station, when the wireless communication is the indirect wireless communication. The method continues with the access point converting the frame into at least one alternate frame based on the protocol of the at least one of the target stations having the different protocol.

Abstract: One or more processors are configured to associate a first local IP address with a computer while the computer is connected to a first network access node thereby providing the computer with access to a network. The first local IP address is one of a plurality of local IP addresses used on the network. The one or more processors monitor transmissions received from the first network access node to determine when the computer requests an Internet transaction.

The first globally unique IP address is disassociated from the first local IP address after termination of the Internet transaction and is then available for association with any of the local IP addresses used on the network.

Abstract: Upon sensing an update of any routing information entry held in a routing information storage unit (A104), an information exchange coordination unit (A105) references a node information storage unit (A102), and if a node information entry corresponding to the updated routing information entry does not exist, acquires the corresponding node information entry from another communication terminal (A1b). Alternatively, upon sensing an update of any node information entry held in the node information storage unit (A102), the information exchange coordination unit (A105) references the routing information storage unit (A104), and if a routing information entry corresponding to the updated node information entry does not exist, acquires the corresponding routing information entry from another communication terminal (A1b). This provides a communication terminal for acquiring both the node information entry and the routing information entry relating to a specific communication terminal substantially at the same time.
