Abstract:

A content addressable merged queue (camQ) architecture for high-speed switch fabrics reduces the memory requirement for crossbar switch input and output queues using memory cells and age tag comparators. CamQ emulates VOQ FIFO for each supporting priority, eliminating HOL blocking. Multiple QoS levels are supported cost effectively at higher traffic bandwidth limits. Content addressable memory (CAM) cells store payload destinations, which can be addressed by cell priorities. Once a priority for QoS is decided, all the cells with the selected priority in the payload can make connection requests to destination ports directly through the CAM structure. An age tag is assigned to incoming cells and fast age tag comparators provide FCFS features by selecting the oldest cell. Small memory sizes prevent the bottlenecking in ingress and egress queues. A CIOQ crossbar has a fast switching speed, emulating a FIFO output queue switch.

US Classification:

370412, 370389, 711108, 365 49

Abstract:

A content addressable merged queue (camQ) architecture for switching data. The camQ architecture comprises a first array of priority cells for indicating a priority of a plurality of cells and a second array of destination cells for indicating a destination of the plurality of cells. A priority selector is operable to select a portion of said plurality of cells according to a priority selection. A grant generator is operable to grant at least one connection request associated with cells of the portion.

Abstract:

A method efficiently multicasts data within a crossbar switch based structure. Multicasting is achieved with effective prioritization of multicast data with respect to unicast data and other multicast data, yet does not unnecessarily delay unicast traffic. The method for multicast service in a crossbar switch effectuates the transfer of data between a single input queue and a multiplicity of output ports and reconfigures the crossbar switch accordingly. A primacy is assigned to data cells based upon their designation as multicast cells that hightens their service priority with respect to cells that are to be unicasted. To prioritize multicast cells for service with respect to other multicast cells, a comparison of assigned priorities is made. While multicast cells have priority in one embodiment over unicast cells, unicast cells can be transferred during multicast iterations during pauses in multicast data transfer.

Abstract:

A preference programmable first-one detector and quadrature based random grant generator in a crossbar switch is disclosed. The crossbar switch emulates a FIFO switching function in a single chip crossbar switch architecture that operates at a high switching speed with a large bandwidth and supports multiple QoS levels, yet do not demand an inordinately large number of input and output queues or otherwise excessively tax memory requirements. The system and method operate at a high switching speed with a large bandwidth and support multiple QoS levels, yet do not require a complex pointer management system, nor constrain switching speeds and bandwidth capacity therein. The system and method efficiently select data for switching within a crossbar switch based structure based on an urgency counter based WRR grant selection. This switching is achieved with economy of hardware by quadrature basing and quadrature preference selection.

US Classification:

37039542, 370412, 370428, 700240

Abstract:

A method and system for switching data in a data switch. In one embodiment, the present invention comprises receiving a plurality of cells at a merged input queue of the data switch, wherein a cell of the plurality of cells is characterized by a priority and a destination. In one embodiment, the destination identifies an output port of the data switch. An age tag is assigned to at least one cell of the plurality of cells. In one embodiment, the age tag indicates the relative length of time a cell of has been in the merged input queue as compared to other cells of the plurality of cells. A portion of the plurality of cells is selected according to a priority selection. It is determined whether any cells of the portion have the same destination. At least one connection request associated with cells of the portion is transmitted, wherein cells having the same destination are transmitted according to the age tag.

Abstract:

Modification of the presentation of page appearance, page navigation flow, and other aspects of the user experience of an online shopper navigating the virtual shopping cart and checkout pages of an online store is achieved without compromising the security of checkout processing. The modification may include customization, and various configuration and customization tools may be employed. The online shopper experiences continuity between unsecured-connection pages presenting items for purchase and secured-connection pages presented for checkout processing. In one embodiment, page navigation flow is modified using continuations implemented using a relatively small stack to save information relating to the flow. In another embodiment, a page designer enables a dynamic version of a page specification program to be generated, such as by way of a page customization interface. Partial evaluation is employed to generate a version of the program that is executed at request time.
