Generic Stream Encapsulation

Generic Stream Encapsulation, or GSE for short, is a data link layer protocol defined by DVB. GSE provides means to carry packet oriented protocols such as IP on top of uni-directional physical layers such as DVB-S2, DVB-T2 and DVB-C2. GSE provides additional features beyond the pure carriage of IP datagrams that increase the protocol flexibility and applicability.
