Abstract: A method for Internet delivery in a delivery network established at network locations, the delivery network comprising a plurality of content servers for serving resources. The servers include a plurality of subsets, each subset being located at one of a plurality of Internet data centers. For each Internet Protocol (IP) address block from which requests for content resources are expected to be received, the method generates a candidate list of data centers to be used to service the requests. For the IP address block, the method selects at least one of the data centers from the candidate list. The selected Internet data center for the IP address block is written into a network map. In response to a DNS query, the map is used to identify one of the Internet data centers from the candidate list to be used to service a request for a content resource.

Abstract: A method for Internet content delivery in a content delivery network established at network locations, the content delivery network comprising a plurality of content servers for serving content resources. The plurality of content servers includes a plurality of subsets of content servers, each subject being located at one of a plurality of Internet data centers. For each Internet Protocol (IP) address block from which requests for content resources are expected to be received, the method generates a candidate list of Internet data centers to be used to service the requests for content resources. For the IP address block, the method selects at least one of the Internet data centers from the candidate list to be used to service the requests for content resources. The selected Internet data center for the IP address block is written into a network map.

Abstract: A seller may sell advertisements, such as banner ads, to a buyer pursuant to a request made by the buyer to the seller. Each request has a value. The seller may accept the request from the buyer to provide a banner ad for the buyer at a later time. A request, once accepted, may be revoked at a cost which may be a fixed fraction of the request value. The cost may be referred to as a buyback cost. The buyback cost represents the cost of revoking a request that had been accepted. Additionally, matroid set systems and knapsack systems may use buyback techniques.

Abstract: An auction may include a general schema to create incentives for those agents or bidders to bid on items at auction truthfully. The schema may implement any allocation rule, including a monotone allocation rule. The schema may provide for accepting bids from bidders, transforming the bids in a manner appropriate to the item being auctioned, and applying the allocation rule on the transformed bid. The schema may further provide for providing a rebate or payment back to the bidders.
