PCoIP Packet Format
PCoIP is a real-time technology that uses UDP as the transport-layer protocol. PCoIP supports two
encryption types—UDP-encapsulated ESP and native IPsec ESP. An unencrypted PCoIP transport
header
fi eld is also present for devices with fi rmware 4.1.0 or later installed and/or for scenarios
using View 5.1 or later. The PCoIP transport header enables network devices to make better QoS
decisions for PCoIP tra
ffi c.
UDP-encapsulated ESP Packet Format
UDP-encapsulated ESP is the default packet format for Tera2 devices with fi rmware 4.1.0 installed.
It is also used for Tera1 devices with fi rmware 3.x+ installed that connect remotely via a View
Security Gateway.
The UDP-encapsulated ESP packet format is illustrated in the following fi gure. This fi gure also
shows the location of the PCoIP transport header in a UDP-encapsulated ESP packet.

TCP/UDP port 4172 assigned to the PCoIP protocol
TCP/UDP port 4172 is the Internet Assigned Numbers Authority (IANA) port assigned to the PCoIP protocol. UDP port
4172 is used for the session data, and TCP port 4172 is used for the session handshake. For more information about
TCP/UDP ports that are used for PCoIP technology, see
