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.

An optical switch includes a light transmitting/receiving sub-assembly and a reflecting device rotatable relative to and confronted with the light transmitting/receiving array sub-assembly. The reflecting device includes two reflecting strips perpendicular to each other. One of the reflecting strips is consisted of two symmetrically arranged 90-degree angled mirrors, and the other includes four symmetrically arranged 90-degree angled mirrors. The sub-assembly includes two linear arrays of collimators which are positioned on a circular disk and are perpendicular to each other corresponding to the two reflecting strips. The collimators of each collimator array are equally spaced from each other. By rotating the light transmitting/receiving sub-assembly with respect to the reflecting device, the light from the light transmitting/receiving sub-assembly is switched between the reflecting strips of the reflecting device.

A method of manufacturing a collimating assembly includes the following steps: preparing a GRIN lens subassembly; preparing a dual-fiber (DF) pigtail subassembly; fitting the GRIN lens subassembly and the DF pigtail subassembly together; applying epoxy onto a junction zone between the GRIN lens subassembly and the DF pigtail subassembly; and baking the junction zone for curing the epoxy thereof until the epoxy spreading uniformly over the junction zone due to the so-called capillarity phenomenon.

An optical add-drop multiplexer comprises an optical switch () for selection of a desired wavelength channel to be extracted, a pre-processing channel assembly (), an optical reflector (), an optical extractor (), a post-processing channel assembly (), and an optical coupler () aligned with the post-processing channel assembly. The pre-processing channel assembly transmits a multiplexed signal stream containing a plurality of channels. The optical reflector directs light rays emitted from the pre-processing channel assembly into the optical extractor. The optical extractor comprises a narrow bandpass filter () that allows a desired channel to pass therethrough and reflects other unextracted channels. The desired channel can be dropped by switching to a corresponding output port of the optical switch. The optical reflector directs light rays reflected from the optical extractor to the post-processing channel assembly.

The present disclosure relates to whole program analysis and, more particularly, short data optimization obtained through whole program analysis. In one embodiment, short data optimization is achieved by analyzing the program to estimate the size of existing short data and the size of any linkage tables, providing the size estimates to a compiler that is to compile the program, and compiling the program with the compiler in view of the size estimates such that a relatively large amount of data is allocated to a short data area.

Techniques for cloning programming code are disclosed. In an embodiment, the cloned code is in the form of functions in the C language. Further, in a method embodiment, a clone of a function is invoked, and information mapping the clone to the function is generated. At link time, if no function body of the clone is accessible by a linker, then the linker uses information mapping the clone to the function to satisfy a linker's requirement. At load time, if no function body of the clone is accessible by a loader, then the loader, based on the mapping information, allows selection of a body of the function. However, if the body function of the clone is accessible by the loader, then the loader allows selection of the body of the clone.

Method and architecture for facilitating payment to e-commerce merchants via a payment service. The method enables consumer users of an electronic storefront hosted by a merchant to make purchases via the payment service, wherein interactions between the electronic storefront and the payment service are transparent to the user. In response to a user check-out request, the user's browser is directed to a payment service web site. Information from which authorization for use of the payment service may be determined is passed to the payment service. The payment service then returns the browser to a selected check-out flow hosted by the electronic storefront, wherein the check-out flow provides an option to use the payment service if the user and merchant are authorized to do so, otherwise the check-out flow does not include the payment service option. In one embodiment, an application program interface (API) provided by the payment service is employed by the electronic storefront to facilitate transactions with the payment service.
