International Classification:

Abstract:

The invention provides a method and system for content-based filtering of multicast information. A set of sources (S) which desire to distribute potentially large numbers of categories of differing information each associates a content descriptor (CD) with messages including information in those categories, so that a set of recipients (R) can receive information in at least some of those categories. A mapping server (M) associates a multicast address (MA) and a content mask (CM) with each content descriptor, so that network elements (N), such as routers, in the network can distribute only those messages which are of interest to recipients in multicast distribution trees for those multicast addresses. Each source generates content descriptors for each differentiable topic in a tree structured hierarchy, and obtains a multicast address and a content mask for the broadest content descriptor it is capable of distributing. Each recipient obtains the associated source, multicast address, and content mask, for each content descriptor of interest, and uses that information to join the multicast distribution tree for that information.

International Classification:

H04L 1256

US Classification:

370422, 370229, 3703951

Abstract:

A packet-switch system utilizes a linecard-to-switch (LCS) protocol to integrate linecards with a switch core. Since the linecards include a majority of the buffering of the system and are located physically away from switch core, the size of the switch core can be reduced in size. The LCS protocol is a label-swapping, credit-based, flow-control, which enables the system to operate without requiring such information as the number of port modules available within a switch core or what Qualities of Service (QoS) or multicast flows are available. In addition, the LCS protocol enables the linecards to contain and manage the majority of the buffers in the system, and also to control the data drop policy within the system.

International Classification:

H04L 12/56

US Classification:

370392

Abstract:

A router receives destination address information for a packet and determines, among entries in a first forwarding table, a closest match for the received destination address information. The router receives a pointer to a second forwarding table in accordance with the closest match determined in the first forwarding table and determines, among entries in the second forwarding table, a closest match for the received destination address information.

Abstract:

The NYTBridge allows a user to bridge the gap between data collected by hand-held scanning devices and conventional databases used in the field of inventory management without database or procedural programming knowledge on the part of the user. The NYTBridge does this by first allowing the user to access an existing database. The user may then select data fields, such as the location of an item in inventory, from the database without writing coded database queries. The NYTBridge then allows the user to download the selected data fields as a data set along with a scanner program that will read the created data set. Both the data set and the scanner program are either saved on a PCMCIA card to be used in a scanner, or downloaded directly into the hand held scanner via either serial port communication or communication dock tethering. When the scanner program is run on the scanner, the scanner program creates a scanner file for the collected, verified and/or corrected data. After the data is collected, verified and/or corrected, NYTBridge reads the scanner file from the hand held scanner and allows the user to update the relational database.
