摘要：
A method and system to identify an overload state in a remote network device within a communications network in which a local network device can send at least one message to the remote network device. The method comprises detecting at least one message transmission timeout for the message sent from the local network device to the remote network device, the message transmission timeout corresponding to a retransmission of the message from the local network device to the remote network device. The number of message transmission timeouts for the message or several messages is counted, with the method further comprising comparing the number of message transmission timeouts to a predetermined timeout threshold so that an overload state for the remote network device can be inferred when the number of message transmission timeouts exceeds the predetermined timeout threshold.
