A switching device in a network system for transferring data includes one or more source line cards, one or more destination line cards and a switching fabric coupled to the source line cards and the destination line cards to enable data communication between any source line card and destination line card. Each source line card includes a request generator to generate a request signal to be transmitted in order to obtain an authorization to transmit data. Each destination line card includes a grant generator to generate and send back a grant signal to the source line card in response to the request signal received at the destination line card to authorize the source line card to transmit a data cell to the destination line card.

Switching device for routing packets through a network

Switching device

A switching device includes multiple interfaces and a switch fabric. The switch fabric includes switch integrated circuits arranged in a number of stages. Multiple virtual switch planes may be implemented in the switch fabric. Data traffic received at the interfaces is selectively assigned to different ones of the virtual switch planes.

Systems and methods for implementing virtual switch planes in a physical switch fabric

A switch fabric includes input links, output links, and at least one switching element. The input links are configured to receive data items that include destination addresses. At least some of the data items have different priority levels. The output links are configured to output the data items. Each of the output links is assigned multiple ones of the destination addresses. Each of the destination addresses corresponds to one of the priority levels. The switching element(s) is/are configured to receive the data items from the input links and send the data items to ones of the output links without regard to the priority levels of the data items.

Packet prioritization systems and methods using address aliases

A high speed transmission system transfers data streams over a plurality of data links. Each data link may carry a number of bit streams. A clock signal is not transmitted over the optical link. Instead, an indication of the appropriate clock signal frequency and phase is embedded in the transmitted data. At the receiving end, a clock signal of an appropriate frequency and phase is generated. The new clock signal is used to sample and reconstruct the original data streams.

Source synchronous link with clock recovery and bit skew alignment

A high speed transmission system transfers data streams over a set of data links. Each data link may carry a number of bit streams. A clock signal is not transmitted over the optical link. Instead, an indication of the appropriate clock signal frequency and please is embedded in the transmitted data. At the receiving end, a clock signal of an appropriate frequency and phase is generated. The new clock signal is used to sample and reconstruct the original data streams.
