The $10$ fields in the header are:

Source Address: $28-$bit network address of the transmitting host

Destination Address: $28-$bit network address of the receiving host

Source Port $($SP$$ in the diagram above$)$: $4-$bit network port of the transmitting host

Destination Port $($DP$)$: $4-$bit network port of the receiving host

Fragment Offset: $14-$bit byte offset of the payload$$s integer in the original array

Packet Length: $14-$bit total length of the packet in bytes, including the header and payload

Maximum Hop Count $($MH$)$: $5-$bit field providing the maximum number of routers the packet may visit while traveling from the source to the destination.

Checksum: the $23-$bit remainder of dividing the sum of:

all of the fields $($except for the Checksum itself$)$ and

the absolute values of the $32-$bit integers in the payload

by the divisor $223-1.$ Again, this is a fictional network protocol. This checksum calculation will accept corrupted payloads!

Compression Scheme $($C$)$: $2-$bit field providing the ID # of the compression scheme used to compress the payload.

Traffic Class $($TC$)$: $6-$bit field used to indicate the quality of service required by this packet.
