摘要： Systems and methods to forward data frames are provided. A particular method may include evaluating address data of a first data frame at a first virtual bridge coupled to a first virtual machine of a first server computer of a plurality of server computers. Based upon the evaluation at the first virtual bridge, the first data frame may be forwarded to a second virtual bridge associated with an adapter that is coupled to the first virtual machine. The address data of the first data frame may be evaluated at the second virtual bridge. Based upon the evaluation, the data frame may be forwarded to a third virtual bridge configured to forward the data frame based upon the address data to a second server computer of the plurality of server computers.

摘要： Techniques are provided for hash-based routing table management in a distributed network switch. A frame having a source address and a destination address is received. If no routing entry for the source address is found in a routing table of a switch module in the distributed network switch, routing information is determined for the source address and a routing entry is generated. The routing table is modified to include the routing entry and based on a set of hash functions.

摘要： Techniques are provided for hash-based routing table management in a distributed network switch. A frame having a source address and a destination address is received. If no routing entry for the source address is found in a routing table of a switch module in the distributed network switch, where the routing table is divided into slices of buckets, then routing information is determined for the source address and a routing entry is generated. The routing table is modified to include the routing entry and based on a set of hash functions and properties of the slices.

摘要： Techniques are provided for routing table synchronization for a distributed network switch. In one embodiment, a first frame having a source address and a destination address is received. If no routing entry for the source address is found in a routing table of a first switch module, routing information is determined for the source address and a routing entry is generated. An indication is sent to a second switch module, to request a routing entry for the source address to be generated in the second switch module, based on the routing information.

摘要： Systems and methods to forward data frames are provided. A particular method may include receiving a data frame at a distributed virtual bridge. The distributed virtual bridge includes a first bridge element coupled to a first server computer and a second bridge element coupled to the first bridge element and to a second server computer. The distributed virtual bridge further includes a controlling bridge coupled to the first bridge element and to the second bridge element. The controlling bridge includes a global forwarding table. The data frame is forwarded from the first bridge element to the second bridge element of the distributed virtual bridge using address data associated with the data frame. A logical network associated with the frame may additionally be used to forward the data frame.

摘要： A processor node of a network is provided which includes one or more processors and a virtualized channel adapter. The virtualized channel adapter is operable to reference a table to determine whether a destination of the communication is supported by the virtualized channel adapter. When the destination is supported for routing via hardware, the virtualized channel adapter is operable to route the communication via hardware to at least one of a physical port and a logical port of the virtualized channel adapter. Otherwise, when the destination is not supported for routing via hardware, the virtualized channel adapter is operable to route the communication via firmware to a virtual port of the virtualized channel adapter. A corresponding method and a recording medium having information recorded thereon for performing such method are also provided herein.

摘要： Performance counters are provided for virtualized network interfaces of communications networks, while minimizing the use of hardware resources. A virtualized network interface includes physical resources, as well as logical resources. Dedicated performance counters are provided for the physical resources of the virtualized network interface, as well as for logical partitions coupled to that interface, while non-dedicated performance counters are provided for the logical resources. This enables the provision of performance counters for virtualized network interfaces, while minimizing hardware resources consumed by those interfaces.
