OSPF have five types of packets.
Hello packets are used to discover and maintain neighbor relationship. In a broadcast or NBMA network, Hello packets are also used to elect the DR and BDR.
Database Description packets describe the link state summary information through carrying LSA header information.
Link State Request packets are used to send the download request information of LSA. Those LSAs are found by receiving DD packets, but the router does not originally have them.
Link State Update packets synchronize the link state database by sending LSA details.
Link State Ack packets ensure that the exchanging process of routing information is reliable through flooding confirm information.
In addition to the Hello packets, all other packets can be sent only between the router with adjacency relations.
