Abstract: In one embodiment, an electronic device maintains one or more tunnel-based overlays for a communication network. The communication network includes two or more physical provider networks. The device maintains a mapping between a particular application and the one or more overlays for the communication network. The device adjusts the mapping between the particular application and the one or more overlays for the communication network. The device causes one or more routers in the communication network to route traffic for the particular application according to the adjusted mapping between the application and the one or more overlays for the communication network.

Abstract: Techniques are provided for performing web authentication of mobile wireless devices that roam from a wireless wide area network to a wireless local area network. A redirect rule is invoked when a request is received from the mobile wireless device for world wide web access in order to obtain authentication for the mobile wireless device before permitting world wide web access. When a world wide web access request is received from the mobile wireless device, it is redirected to an authentication portal to allow a user of the mobile wireless device to enter user credentials to allow for world wide web access using the IP address.

Abstract: An array architecture built out of content addressable memories (CAMs) is disclosed. This architecture is re-programmable and exhibits pre-synthesis deterministic timing behavior. This architecture can be re-programmed to store control-flow as well as data-flow dominated applications. The target application is partitioned into basic functional units, which are then transformed to a representation suitable for storage in CAMs.

Abstract: Disclosed is a design detail for an innovative time multiplexed read port architecture implemented as part of a high-speed 9-port time slot interchange random access memory. It provides a practical, high-speed, low-power and area efficient read port structure to allow eight random access reads per clock cycle. Because all timing is internally generated from a single rising clock transition of a system clock signal, no special control or clocking is required externally to the memory.

Abstract: A multi-port SRAM (static random access memory) core array has a core cell with a single-ended, pseudo-differential write access port and differential, indirect access read ports. The architecture of the features of the multi-port SRAM core array allows direct scaling of the number of write and read access ports to any practical limit with no adverse effects on cell stability margins and therefore data integrity.
