CSTP is a Cisco proprietary protocol for SSL VPN tunneling. “In” means “from the
client” and “Out” means “to the client”. The client is the PC running the Cisco
AnyConnect VPN Client software that connects to the security appliance running
the SSL VPN server.
A CSTP frame is a packet carrying CSTP protocol information. There are two
major frame types, control frames and data frames. Control frames implement
control functions within the protocol. Data frames carry the client data, such as the
tunneled payload.
