| 20090234974 | PERFORMANCE COUNTERS FOR VIRTUALIZED NETWORK INTERFACES OF COMMUNICATIONS NETWORKS - 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. | 09-17-2009 |
| 20110243134 | Data Frame Forwarding Using a Distributed Virtual Bridge - 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. | 10-06-2011 |
| 20110243146 | Data Frame Forwarding Using a Multitiered Distributed Virtual Bridge Hierarchy - 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. | 10-06-2011 |
| 20110246692 | Implementing Control Using A Single Path In A Multiple Path Interconnect System - A method and circuit for implementing control using a single path in a multiple path interconnect system, and a design structure on which the subject circuit resides are provided. Control TL messages include control information to be transferred between a respective source transport layer of a source interconnect chip and a destination transport layer of a destination interconnect chip. Each transport layer (TL) includes a TL message port identifying a port used to send and receive control TL messages for a pair of source TL and destination TL. The respective TL message port of the pair of source TL and destination TL defines the single path used for control messages. | 10-06-2011 |
| 20110258340 | Distributed Virtual Bridge Management - Systems and methods to forward data frames are described. A particular method may include receiving a data frame at a switch of a plurality of networked switches coupled to a plurality of server computers. The data frame may be forwarded from a controlling bridge coupled to the plurality of networked switches. The data frame may be determined to include management data, and an operating parameter of the switch may be modified. | 10-20-2011 |
| 20110261815 | Multicasting Using a Multitiered Distributed Virtual Bridge Hierarchy - Systems and methods to multicast data frames are provided. A particular apparatus includes a plurality of computing nodes and a distributed virtual bridge. The distributed virtual bridge includes a plurality of bridge elements coupled to the plurality of computing nodes. The plurality of bridge elements are configured to forward a copy of a multicast data frame to the plurality of computing nodes using group member information associated with addresses of the plurality of server computers. A controlling bridge coupled to the plurality of bridge elements is configured to communicate the group member information to the plurality of bridge elements. | 10-27-2011 |
| 20110261837 | IMPLEMENTING END-TO-END CREDIT MANAGEMENT FOR ENHANCED LARGE PACKET REASSEMBLY - A method and circuit for implementing end-to-end credit management for enhanced large packet reassembly in an interconnect system, and a design structure on which the subject circuit resides are provided. A transport layer provides buffering and credit control for a super packet received from a source device. A source transport layer sends an End-to-End (ETE) credit request message to a destination transport layer for an outstanding super packet transmission to a destination device. The destination transport layer grants credit to allow at least one source to send a super packet to the destination. The source transport layer fragments the super packet into multiple packets and sends all packets of the super packet only responsive to the credit request being granted by the destination transport layer that is needed to send all packets of the super packet. | 10-27-2011 |
| 20110264610 | Address Data Learning and Registration Within a Distributed Virtual Bridge - Systems and methods to forward data frames are provided. A particular apparatus may include a plurality of server computers and a distributed virtual bridge. The distributed virtual bridge may include a plurality of bridge elements coupled to the plurality of server computers and configured to forward a data frame between the plurality of server computers. The plurality of bridge elements may further be configured to automatically learn address data associated with the data frame. A controlling bridge may be coupled to the plurality of bridge elements. The controlling bridge may include a global forwarding table that is automatically updated to include the address data and is accessible to the plurality of bridge elements. | 10-27-2011 |
