Abstract: Overload of a source included in a network is prevented. Each packet of a plurality of packets is transmitted, via the network, between at least one source and at least one intended destination. The network is interfaced between each of the at least one source and each of the at least one intended destination. Each packet of at least a subset of packets of the plurality of packets is intercepted at the interfacing. For each intercepted packet, it is determined whether the intercepted packet is transmitted from one source to one intended destination or is transmitted from one intended destination to one source. For each of the at least one intended destination, each intercepted packet transmitted thereto or received therefrom is accounted based on the determining. An action is taken based on the accounting.
