摘要： One embodiment of the present invention provides a switch. The switch includes a virtual local area network (VLAN) configuration module. During operation, the VLAN configuration module maps local resources of the switch and/or locally coupled end device information to a global VLAN identifier, wherein the global VLAN is persistent across a fabric switch. The fabric switch is operable to accommodate a plurality of switches and operates as a single logical switch.

摘要： In some embodiments, a switch fabric system includes multiple access switches configured to be operatively coupled to a switch fabric. The multiple access switches include multiple ports each to be operatively coupled to a peripheral processing device. A first set of ports from the multiple ports and a second set of ports from the multiple ports are managed by a first network control entity when the switch fabric system is in a first configuration. The first set of ports is managed by the first network control entity and the second set of ports is managed by a second network control entity when the switch fabric system is in a second configuration. The second network control entity is automatically initiated when the system is changed from the first configuration to the second configuration.

摘要： A data transfer device 210 is equipped with a plurality of communication ports 211a and 211b, a communication establishment processor 212, and a communication maintenance processor 213. The communication establishment processor 212 transmits and receives communication establishing information for establishing communication with an external device connected via the communication port to and from the external device. The communication maintenance processor 213 is configured to operate independently of the communication establishment processor 212 and, every time a predetermined transmission period elapses, transmits communication maintaining information for maintaining the establishment of communication with the external device, to the external device. In a state that communication with a plurality of external devices via the plurality of communication ports is established, the data transfer device 210 transmits data received from one of the plurality of external devices to the other one of the plurality of external devices.

摘要： Techniques are provided for updating routing tables of switch devices. At a first switch device of a first rack unit in a network, information is received about addresses of host devices in the network. The addresses are stored in a software cache. A packet is received from a first host device assigned to a first subnet and housed in the first rack unit. The packet is destined for a second host device assigned to a second subnet and housed in a second rack unit in the network. The packet is forwarded using the subnet entry and it may remain sub-optimal during a period before which an entry can be installed form a software cache. The software cache is evaluated to determine the address of the second host device. The packet is then forwarded optimally. This will ensure any-to-any communications in the network initially sub-optimally and subsequently optimally.
