Abstract: An approach for supporting inter-domain routing of a packet is provided. A communication system includes a plurality of terminals having full meshed connectivity, in which each of the terminals is configured to route the packet to one of a plurality of address domains (i.e., terminal is multi-homed) and to notify a source terminal originating the packet of a correct one of the terminals. An address server assigns a network address corresponding to the one address domain based on a destination address associated with the packet, wherein the source terminal routes the packet according to the assigned network address. The present invention has particular applicability to a fully meshed satellite network.

Abstract: A nanocomposite optical plastic article has a plastic host material with a temperature sensitive optical vector (x) and a core shell nanoparticulate material dispersed into the plastic host material. The core shell nanoparticulate material is characterized by a core defined by a nanoparticulate material which has a temperature sensitive optical vector (x1) and a shell defined by a coating material layer coated onto the core. It is important to the invention that temperature sensitive vector (x1) is directionally opposed to the temperature sensitive optical vector (x) and nshell<nplastic host<ncore.

Abstract: A laser array and method of making same has precision fiducial marks that aid in the alignment of the laser array. The invention requires forming additional optical features adjacent to the laser array that is used to write fiducial marks on an opposite surface in the medium containing the laser array. Fiducial marks are formed when high intensity collimated beams of light are directed through the optical features onto a treated portion of the transparent medium. Fiducial accuracies of 1 micron are possible by using this approach.

Abstract: An approach is provided for supporting retrieval of a web page over a data network from a web site is disclosed. A downstream proxy communicating with a host executing a browser receives a request message from a browser to retrieve the web page. An upstream proxy parses the web page to determine an object embedded in the web page, wherein a promise list is generated specifying the embedded object that is to be pre-fetched according to a criterion. The promise list is transmitted to the downstream proxy, wherein the upstream proxy pre-fetches the embedded object from the web site. The upstream proxy determines whether to forward one of the pre-fetched embedded object to the downstream proxy based on a comparison of cookies associated with one of the pre-fetched objects supplied, respectively, by the browser and the web site. This approach as particular applicability in relatively high latency networks, such as a satellite communications system.

Abstract: A communication system for retrieving web content is disclosed. A downstream proxy server receives a URL request message from a web browser, in which the URL request message specifies a URL content that has an embedded object. An upstream proxy server receives the URL request message from the downstream proxy server. The upstream proxy server selectively forwards the URL request message to a web server and receives the URL content from the web server, wherein the upstream proxy server forwards the URL content to the downstream proxy server and parses the URL content to obtain the embedded object prior to receiving a corresponding embedded object request message initiated by the web browser.

Fiducial mark is formed on the surface that enables precise alignment of the micro-sized articles.

Abstract: An approach for routing over a radio network is provided. A terminal receives a packet over the radio network, which supports meshed connectivity, wherein the packet is destined for a destination host. The terminal determines whether the destination host is reachable by a communication interface based upon a route table, and selectively redirects the packet over the radio network according to the route table. A route server is provided to collect routes from the terminal as well as other terminals within the radio network. The route server then disseminates the collect routes to the terminals for updating of their respective route tables. The present invention has particular applicability to a fully meshed satellite network.

Abstract: A method is disclosed for making deep microstructures in photoresist. The method utilizes a pool of photoresist on top of a transparent substrate and the laser is located below the substrate. Structures are created in the photoresist by transmitting the laser light through the substrate up into the photoresist. Since the photoresist does not have to be spin coated onto the substrate, very thick layers of photoresist can be used while the thickness uniformity is determined by the substrate surface. Alternately, a contoured substrate can be used while producing uniform structures.
