Methods for generating comparison shopping data are provided. One example method includes receiving a request for a desired item and generating an item table for the desired item. The item table is assembled from current on-line data that includes e-commerce purchasing information. Once the item table is assembled, the item table is displayed for the requested item such that the displayed information can inform an on-line buyer of the best current purchasing alternatives for the requested item. In one aspect of this method, the desired item can be selected form a data base of classified advertising. Once the classified advertising item is selected, the item table is generated and displayed along with the selected classified advertising item. In one example, the item table can include merchant name information, price information, availability information, new and used information, tax and shipping information, prior purchaser ratings, and total cost information. The displayed information will therefore provide an on-line purchaser with a powerful array of information to enable the making of an intelligent on-line purchasing decision.

A packet mapper prioritizes streams of data packets in a computer network, each data packet having a packet header containing feature values descriptive of the data packet. The packet mapper includes a mapping table that associates application-related features with network-reserved feature values from a range of feature values reserved for use by selected network data packet streams, and a feature value mapper that performs at least one of (i) in each packet header having an application-related feature value associated with a network-reserved feature value, substituting the associated network-reserved feature value for the application-related feature value, and (ii) in each packet header having a network-reserved feature value associated with an application-related feature value, substituting the associated application-related feature value for the network-reserved feature value.
