摘要： In general, techniques are described in which a plurality of network switches automatically configure themselves to operate as a single virtual network switch. A virtual switch is a collection of individual switch devices that operate like as single network switch. As described herein, network switches in a network that are capable of participating in a virtual switch may automatically discover one another. The participating network switches may then elect one of the participating switches as a master switch. The master switch may generate forwarding information and store the forwarding information in the participating switches, including the master switch. The forwarding information causes the participating switches to act like a single network switch.

摘要： Access switches in a switching system may use virtual aggregated links. When a link between an aggregation switch and an access switch fails, the link failure may be reflected in the virtual aggregated link and data traffic to another access switch may be switched away from the failed switch. A forwarding table in the access switch stores a number of entries that each define a correspondence between destination addresses and an output identifier for the switch. At least a first output identifier includes an aggregated link that represents a first set of possible output links. At least a second output identifier includes a virtual aggregated link, associated with a second network switch that represents a second set of possible output links. Destination addresses in the forwarding table for the virtual aggregated link correspond to network devices connected to the second network switch.

摘要： A bus arbitration system and method allocates total bus bandwidth between latency sensitive and latency insensitive interfaces by utilizing windows to divide the total bandwidth into latency sensitive and latency insensitive portions. Each interface is initially allocated top-up numbers of latency sensitive and latency insensitive tokens to proportionally allocate bus accesses between the interfaces according to their requirements. For an interface having access to the bus, the number of tokens is decremented for each successful bus transfer.

摘要： A virtual device includes multiple devices connected to operate as a single device. A first one of the devices is configured to determine that the first device connects to a second one of the devices via a first link; identify a second link; determine that the second link connects the first device to the second device; and automatically aggregate the first link and the second link to form a link aggregation with the second device based on determining that the first device connects to the second device via both the first and second links. The first device is further configured to transmit packets to the second device via the first and second links of the link aggregation.
