Patent ID: 8422358

Claim:
A method for dynamic error dampening in a node in a network system comprising a management node, the method comprising: retrieving statistics of data traffic of the node, wherein said statistics comprises a number of total incoming packets (INt), a number of erred incoming packets (INe), a number of total outgoing packets (OUTt), and a number of erred outgoing packets (OUTe), wherein the node comprises a link error Management Information Base (MIB); calculating Error ratio value (E) and Reliability value (R) of the link error MIB based on said statistics from said retrieving, wherein 0≦R≦1; determining that the Error ratio value (E) is greater than Threshold, and subsequently starting an error measure protocol for monitoring the data traffic over Layer 2 link of the node and calculating Penalty value (P) of the node as (MaxPenalty*(1−R)), wherein MaxPenalty is a preconfigured upper bound of the Penalty value (P); and ascertaining that the Penalty value (P) from said initializing falls in a range selected from the group consisting of a first range wherein (Suppress Threshold (ST)<P), a second range wherein (Reuse Threshold (RT)<P≦ST), a third range wherein (0<P≦RT), and a fourth range wherein (P=0), wherein the first range is associated with recalculating the Penalty value (P) as (P*(1−R)), and deactivating Layer 3 link of the node, wherein the second range is associated with continuing of transferring the data traffic, wherein the third range is associated with said recalculating and reactivating the Layer 3 link of the node, and wherein the fourth range is associated with said reactivating and resetting of monitoring the Error ratio value (E).
