摘要： Method and apparatus for dynamic Node healing in a Multi-Node environment. A multi-node platform controller hub (MN-PCH) is configured to support multiple nodes through use of dedicated interfaces and components and shared capabilities. Interfaces and components may be configured to be used by respective nodes, or may be configured to support enhanced resiliency as redundant primary and spare interfaces and components. In response to detecting a failing or failing primary interface or component, the MN-PCH automatically performs failover operations to replace the primary with the spare. Moreover, the failover operation is transparent to the operating systems running on the platform's nodes.

摘要： An initial request is received to establish a communication session. The initial request contains a communication address of a first communication device. A communication server detects that the communication session cannot be established across a primary network. In response, the initial request is repurposed by changing the first communication address to a second communication address. The changed request is sent to a communication system, which adds a field to the changed request that indicates that the changed request is to be sent via a secondary network. The changed request is sent with the field to the communication server. The changed request with the second communication address is sent to a gateway to establish the communication session across a secondary network. A portion of the communication session is established using the second communication address. The first communication address is sent in the portion of the communication session using Dual-Tone-Multi-Frequency (DTMF).

摘要： A bus interface selects bit-lanes to allocate as spares by testing the performance margins of individual bit-lanes during initialization or calibration of the bus interface. The performance margins of the individual bit-lanes are evaluated as the operating frequency of the interface is increased until a number of remaining bit-lanes that meet specified performance margins is equal to the required width of the interface. The bit-lanes that do not meet the required performance margins are allocated as spares and the interface can be operated at the highest evaluated operating frequency. When an operating bit-lane fails, one of the spare bit-lanes is allocated as a replacement bit-lane and the interface operating frequency is reduced to a frequency at which the new set of operating bit-lanes meets the performance margins. The operating frequency of the interface can be dynamically increased and decreased during operation and the performance margins evaluated to optimize performance.

摘要： In one embodiment, a primary root node may detect one or more neighboring root nodes based on information received from a first-hop node and may select a backup root node among the neighboring root nodes. Once selected, the backup root node may send the primary root node a networking identification and a corresponding group mesh key which the primary root node may forward to the first-hop nodes to cause the first-hop nodes to migrate to the backup root node when connectivity to the primary root node fails. In addition, the first-hop root nodes may migrate back to the primary root node when connectivity to the primary root node is restored.

摘要： Instead of disabling PCI communication between system resources in a host computing device and I/O devices when a PCI Host Bridge (PHB) is unable to function, the host computing device may include a redundant PCI communication path for maintaining communication between the system resources and the I/O devices after a first PHB experiences an unrecoverable error. In one embodiment, the redundant PCI communication path includes a second PHB that is maintained in a standby state so long as the first PHB is functioning normally. However, once the first PHB experiences an unrecoverable error, the second PHB is changed to the master state and assumes the responsibility for maintaining communication between the system resources and the I/O devices.

摘要： Systems and techniques are described which improve performance, reliability, and predictability of networks. Geographically diverse network control nodes (NCNs) are provided in an adaptive private network (APN) to provide backup NCN operations in the event of a failure. A primary NCN node in a first geographic location is operated according to a primary state machine at an NCN active state. A client node is operated according to a client state machine. A secondary NCN node in a second geographic location that is geographically remote from the first geographic location is operated according to a secondary state machine at a standby state. The three state machines operating parallel and upon detecting a change in APN state information, the secondary state machine transitions from the standby state to a secondary active NCN state and the secondary NCN node provides APN timing calibration and control to the client node.
