PFCP Hex Decoder

PFCP is used on N4/Sx interfaces to control user-plane forwarding behavior in EPC/5GC architectures. Header decoding helps trace control transactions between control and user-plane functions.

About PFCP

Packet Forwarding Control Protocol (PFCP) carries session and node control messages for mobile user-plane management. The header reveals message identity, transaction sequence, and session scope.

PFCP is used on N4/Sx interfaces to control user-plane forwarding behavior in EPC/5GC architectures. Header decoding helps trace control transactions between control and user-plane functions.

PFCP Header Structure

Flags/version byte: PFCP version and indicator bits (including SEID presence).
Message Type (1 byte): node/session management operation.
Length (2 bytes): message size after initial bytes.
Optional SEID (8 bytes) when session-scoped signaling is used.
Sequence Number (3 bytes): request/response correlation value.

Why Decode PFCP Packets

Decode PFCP headers from hex including version, message type, length, SEID flag, and sequence number.
