SCTP Packet Structure - Common Header

Common Header

All SCTP packets require the common header section (shown with a blue background).

Source port
This field identifies the sending port.
Destination port
This field identifies the receiving port that hosts use to route the packet to the appropriate endpoint/application.
Verification tag
A 32-bit random value created during initialization to distinguish stale packets from a previous connection.
Checksum
SCTP's original design catered for Adler-32; but RFC 3309 changed the protocol to use the CRC32c algorithm.

Famous quotes containing the word common:

    It is the characteristic of great poems that they will yield of their sense in due proportion to the hasty and the deliberate reader. To the practical they will be common sense, and to the wise wisdom; as either the traveler may wet his lips, or an army may fill its water-casks at a full stream.
    Henry David Thoreau (1817–1862)
