The method includes receiving, by a server node of a network, a feedback message from a downstream server, wherein the feedback message includes a statistic of a communication protocol. The method includes determining, by the server node, which of one or more counters, from an array of counters stored in a computer memory module, are associated with the downstream server using one or more hash functions based on information included in the feedback message, wherein the one or more counters store a number corresponding to how many feedback messages have been received from the downstream server that include the statistic.
The method includes incrementing, by the server node, the one or more counters in response to the feedback message including the statistic. The method includes determining, by the server node, using the one or more hash functions, a value of the number stored in the one or more counters. The method includes determining, by the server node, that the value is indicative of an overload episode in the network for the downstream server based on whether the value satisfies a predetermined criteria. |
