The Reassembly Queue receives fragmented messages (DATA or I-DATA chunks) and - with help of stream reassemblers - will reassemble these fragments into messages, which will be delivered to the client. It also handle partial reliability (FORWARD-TSN) and stream resetting. To avoid a DoS attack vector, where a sender can send fragments in a way that the reassembly queue will never succeed to reassemble a message and use all available memory, the ReassemblyQueue has a maximum size.
