WebAt layer 4 (TCP or UDP) the 'length' covers the layer 4 header and it is tracked in the IP header. This means, for UDP the minimum expected is 8 bytes (for its header). And, for TCP it is 20 bytes (the minimum TCP header). The part you seem to be missing starts now. WebIn each layer we have the following information: getProtocol () - get an enum of the protocol the layer represents getHeaderLen () - get the size of the layer's header, meaning the size of the layer data getLayerPayloadSize () - get the size of the layer's payload, meaning the size of all layers that follows this layer WebThis means that the last protocol header that is added is at the Data Link layer, which means that we should encounter this header first.
