Abstract: Wireless connectivity for data communication is extended to users who are in public transport vehicles such as airliners, corporate aircraft, autobuses, trains and the like. The access allowed is extended to enable communications between such transiting users and between such transiting users and geographically based networks.

Abstract: A searchable information database is provided. At least one network processor having one or more packet processors is provided which are programmed to independently search for a match of any one of the keys in a key set which is delivered to the network processor(s). Each key set is independently identifiable and searchable. If a match is found, then either a function associated therewith or a pointer to the location of the information in the database is returned. Several searching techniques can be used. For example, multiple network processors can be used, with each storing the keys of a different set of keys, and each set of keys can be searched concomitantly in the network processors. Alternatively, a large lookup table may distribute multiple network processors. If a single network processor is used, the key sets can be pipeline searched, or pico processors or packet processors can independently search each key set.

Abstract: Wirelessly connected information handling system devices such as access points and end user devices are Layer 3 aware, particularly in respect to knowing the IP address of the stations wirelessly connected to them. With capability for full Layer 3 functionality, the use of Open Shortest Path First (OSPF) in these products provides a well tested, very robust method moving from a large flat LAN environment to the hierarchical world of IP routing.

Abstract: Provision to a customer of equipment already installed into a specified enclosure to create an assembly is accomplished in an advantageous manner by the disclosed process. A manufacturer obtains the enclosure and the components of the specified equipment, installs the equipment in the enclosure and performs appropriate tests on the completed assembly before sending the assembly to the customer.

Abstract: A system, method and program product for optimizing a product order in real time where the product includes at least one customer-selectable component. Component information such as component cost, delivery lag time and availability are determined in real-time by querying a manufacturer system and, in response to a component being unavailable at the manufacturer, querying at least one supplier system that can supply the component to the manufacturer. The customer is then offered at least one order option in real time based on the results of the determination.

Abstract: A system comprising a network resource server or a server farm formed by a plurality of computer systems and a network processor which transfers data exchanged with an external network supported by the server farm at a data rate substantially the same as the data flow rate of the network and related method. The network processor protects the network resource server against attacks such as a denial of service attack by monitoring data flow, computing a derivative of the data flow over time to determine the rate of change of data flow, and modifying instructions for the discarding of packets in response to rates of change which are outside predetermined boundaries.

Abstract: A LAN switch includes port modules which receive frames from their respective LAN segments and forwards the frames simultaneously to all output ports and to a port look-up function which determines the output port to which the frames should be forwarded. If the port look-up function identifies the output port, frame transmission is halted at all ports except the identified port. By performing the forwarding function and port look-up function simultaneously, a zero latency switch is provided.

Abstract: A multi-port LAN switch is provided that enables attached network devices to both communicate directly and to insert into a token-ring network through an attached concentrator. Each port of the multi-port LAN switch has a first transformer, a second transformer, and a switching system. The first transformer has a first winding connected to a first connection of the port. The second transformer has a first winding connected to a second connection of the port. The switching system switches to a port mode or an adapter mode as a function of a mode signal transmitted to the port. In the adapter mode, the switching system connects a second winding of the first transformer to a transmitter circuit in the port, and its connects a second winding of the second transformer to a receiver circuit in the port.

Abstract: This invention relates to "clear pipe" communication networks meaning the nodes and links handle a variety of data frame types depending on their communication protocols such as Token Ring, Ethernet, FDDI or ATM. More particularly, this invention relates to node/link interface adapters at nodes which include switching nodes and end nodes. The adapters identify data frame type and adapt the node/link adapter operative elements to handle the various types of data frames as they travel through the network.The invention identifies the frame type at the source, flags the frame type to the nodes by use of unique SDEL (start delimiter) symbols or codes, uses the SDEL codes as received with the frame at each node to find the destination address in the frame and to adjust the transmission rate for the frame. The transmission rate is adjusted by inserting null non-data symbols in the frame to effectively slow the data rate to the data rate capacity of the protocol.
