This specification describes Generic TCP Encapsulation (GTE) which is a method to encapsulate packets of different IP protocols within TCP data streams. Encapsulating packets in TCP facilitates communications across networks that block or sub-optimally handle non-TCP traffic. GTE is an adaptation of Generic UDP Encapsulation (GUE) to work in the context of TCP. GTE employs the GUE encapsulation format and optional extensions.
