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:
“This, our respectable daily life, on which the man of common sense, the Englishman of the world, stands so squarely, and on which our institutions are founded, is in fact the veriest illusion, and will vanish like the baseless fabric of a vision; but that faint glimmer of reality which sometimes illuminates the darkness of daylight for all men, reveals something more solid and enduring than adamant, which is in fact the cornerstone of the world.”
—Henry David Thoreau (1817–1862)
