Dynamic error dampening in a network system

摘要

A method and computer system for dynamic error dampening in a node of a network system. Data traffic of the node is implemented in accordance with an Open Systems Interconnection (OSI) network management model that includes a Layer 1 physical link, a Layer 2 link including a data link in which primitive point-to-point data communication with neighboring nodes is enabled upon the Layer 1 physical link, and a Layer 3 link which is a network link operating on top of the Layer 2 link. Implementation of an error dampening process at the node includes deactivating the Layer 3 link of the node while monitoring data traffic over the Layer 2 link of the node. Deactivating the Layer 3 link of the node includes preventing the Layer 3 Link of the node from receiving incoming data traffic for routing to other nodes in the network system.

1. A method for dynamic error dampening in a node of a network system, said method comprising:
retrieving, by a processor of a computer system, statistics of data traffic of data packets at the node; said processor computing an error ratio (E) based on the retrieved statistics such that 0≦E≦1; said processor determining that the computed error ratio exceeds a specified error ratio threshold; and in response to said determining that the computed error ratio exceeds the specified error ratio threshold, said processor implementing an error dampening process at the node, wherein data traffic of the node is implemented in accordance with an Open Systems Interconnection (OSI) network management model that includes a Layer 1 physical link, a Layer 2 link comprising a data link in which primitive point-to-point data communication with neighboring nodes is enabled upon the Layer 1 physical link, and a Layer 3 link which is a network link operating on top of the Layer 2 link, and wherein said implementing the error dampening process at the node comprises deactivating the Layer 3 link of the node while monitoring data traffic over the Layer 2 link of the node, said deactivating the Layer 3 link of the node comprising preventing the Layer 3 Link of the node from receiving incoming data traffic arriving at the node after initiation of said implementing the error dampening process at the node and from routing the incoming data traffic to other nodes in the network system.
