Background
Conventional general Stream Encapsulation protocol Encapsulation (GSE) is a common Encapsulation technique. The Protocol is commonly used for a Digital Video Broadcasting Protocol (DVB-S2 for short), and provides network layer packet encapsulation and fragmentation functions above a general stream format, and a Protocol Data Unit (PDU for short) is encapsulated into a link layer packet with a variable length, and then is filled into a baseband Frame (BBFrame for short) of a physical layer, so as to perform Data transmission.
Fig. 1 is a schematic diagram of a GSE encapsulation and BBFrame relationship in the related art, as shown in fig. 1, a PDU may independently complete one GSE encapsulation, or may be divided into multiple pieces for GSE encapsulation, and the GSE encapsulation is then filled in a BBFrame or other transmission units.
Fig. 2 is a diagram illustrating a first GSE encapsulation format according to the related art, as shown in fig. 2, and fig. 3 is a diagram illustrating a second GSE encapsulation format according to the related art if a PDU is fragmented, as shown in fig. 3, where an unshaded portion is a necessary entry for standard GSE header encapsulation. In the traditional GSE encapsulation, the GSE fragment includes a first fragment indicating bit S (1B), a last fragment indicating bit E (1B), a type flag bit LT (2B), a GSE length indicating bit (12B), an identifier ID (1B), a total packet length (2B), a protocol type indicating bit (2B), a flag type (3-6B), and an extension header indicating bit (> = 2B). The tail slice has CRC check bits (4B). The GSE encapsulation overhead generates a total GSE header length sum for all GSE slices for encapsulating one PDU.
The existing GSE carries out the same GSE header information replacement by identifying the continuous same GSE message header, thereby achieving the purpose of reducing the GSE overhead. The method mainly comprises the following steps: when the number of the continuously identified same message headers reaches a preset threshold value, replacing the message headers with compression indexes, and updating corresponding compression information to an index and compression information table of a sending end; judging whether the first N messages of the first compression of the current message header are the first N messages: if yes, sending the message in a format with the original message after compression; if not, judging whether the current period is in a period of sending the original message: if yes, sending the message in a format with the original message after compression; if not, sending the message in a format without the original message after compression; receiving a message and judging a message header mark: if the format is a format with the original message after being compressed, updating the index and the compression information table of the self, and forwarding the original message; if the format is the format without the original message after being compressed, the original message is restored according to the index and the compressed information table, and the original message is forwarded. The bandwidth of the satellite link is saved, and the message does not need to be modified.
The method is effective when the sending unit is large enough, and is difficult to work when one sending unit cannot complete sending of the whole PDU data if the sending unit is small, that is, N (N > = 2) PDUs are needed for one PDU.
For the problems that the transmission link bandwidth is saved by identifying the same packet header compression in the related art, the packet headers in the transmission frames need to have the same encapsulation structure, and the PDU data cannot be transmitted by a plurality of transmitting units, a solution has not been proposed.

When the GSE protocol is applied to send the message, part of the fields can be optimized according to the actual situation to reduce the length of the packaging overhead. Especially, when the sending unit is small, for example, the sending unit is smaller than the sending message length, the sending message (PDU) is inevitably sent in a fragmentation manner, so that a plurality of GSE fragmentation costs are generated.

Optimization taking the GSELength field as an example: if the GSE encapsulation is in the distribution case 1 and 2, the size of the GSE encapsulation can be calculated from the size of the sending unit and the previous space usage in the same sending unit, and in this case, the GSELength field can be optimized, i.e. omitted. The GSELength field is recorded in the GSE slice with or without an available function field or recorded by other methods.
