Can you explain the interaction process between a UVM agent and a UVM sequencer?

uvm seequencer is mainly for routing the sequence item from the sequence to the
driver, a component inside the uvm agent. sequencer will use seq_item_port to
send the sequence item to driver, and the driver will use
seq_item_port.get_next_item(req) to get the transaction object and send the
information to the interface then to dut. There is not explicit seq_item_port
send action needed to code in uvm_sequencer, it was taken care of in uvm
library. Another thing to do is in the agent level, you need to connect the
sequencer seq_item_export with driver's seq_item_port
