Abstract: Methods, systems and computer program products for delivering content objects over the Internet are disclosed. Use of a packet size digest allows for look-up of known or discovered maximum packet sizes for network paths to various receiving systems by servers within one or more points of presence of a content delivery network, such that the packet size information can be advantageously re-used by the multiple servers to reduce delays associated with lost packets and time spent determining a path maximum packet size or maximum transmission unit by each of the multiple servers within the point of presence as they transmit content objects over the Internet.

Abstract: Techniques for modifying the performance of a transport layer protocol in response to a request for content are disclosed. A connection can be established between a content distribution server and an end user computer according to preconfigured parameters. When a request for content is received over the connection, the content distribution server can determine one or more parameters relating to the performance of the connection using information from the request. The content distribution server can modify the connection at the transport layer according to the one or more parameters. Thereafter, the transport layer can manage delivery of the requested content to the end user computer in accordance with the modified parameters. In various embodiments, the content distribution server includes a modified TCP protocol stack which adjusts timing, pacing, and buffer allocation associated with a connection in response to requests from an application-layer data source.

Abstract: A roofing material fastener comprises a shank having a length dimension and a point. The shank is adapted to enable it to be driven through at least a first course of roofing material and into a roof deck. A fastener head is positioned in a region of the shank distal from the point. A spike protrusion projects from the distal region of the shank to a terminus. The length of the spike protrusion is less than one half the length of the shank, measured from the point to the fastener head. The spike protrusion is adapted to penetrate a depth less than the full depth of a second course of roofing material installed above the first course. The spike protrusion is shaped to inhibit sawing through the second course of roofing material by the spike protrusion.

Abstract: In one embodiment, a system for adapting the interoperation of nodes in an information processing system is disclosed. The system includes a protocol handler, a protocol attribute information store and a protocol attribute selector. The protocol handler manages a first connection and a second connection over the network using a protocol. The protocol attribute information store holds a plurality of attributes. The protocol attribute selector evaluates first information related to a first connection, utilizes the protocol attribute information store to determine first protocol attributes corresponding to the first connection, and communicates the first attributes for the first connection to the protocol handler.

Abstract: A method for thermally revitalizing a damaged polymer-containing material, consisting essentially of applying heat from an external heat source to the surface of the object to temporarily raise the surface temperature of the object above the softening point of the polymer is disclosed. A device for performing thermal revitalization on a polymer-containing material is also disclosed.
