Embodiment Construction

[0015] In order to make the purpose, technical features and implementation effects of the present invention clearer, the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] A general extensible multi-protocol encapsulation method (XPE,) is provided in the embodiment of the present invention, such as figure 1 As shown, in the data link layer, various different service data in the upper layer are encapsulated to form a unified data packet, so as to realize the transmission and reception of service data in the data link layer. For this reason, the embodiment provides two new data packet structures, one is the XPE lower layer link adaptation packet (referred to as the XPE packet), which is used to encapsulate a variety of different service data transmitted to the data link layer; the second The second is the XPE-FEC lower layer link adaptation package (XPE-FEC package for sho...

Abstract

The invention provides a multi-protocol service data packaging and analyzing method, a receiving end and a sending end, wherein the packaging method comprises: creating a data packet which comprises two parts of tips and payloads when a data link layer has service data which needs transmitting, storing the service data into the part of payloads in the data packet, assigning value to each field in the tips of the data packet, thereby realizing the package of the service data. The service data of different modes can be uniformly packed into an XPE / XPE-FEC bag and can be transmitted through defining an XPE bag and an XPE-FEC bag in a link data layer and through applying the technical scheme, and the package of multi-protocol data can be realized, users can conveniently and rapidly receive multi-mode service data, and compatible transmission of the multi-mode service data can be effectively solved.

Description

technical field [0001] The invention relates to data transmission technology, in particular to a method for encapsulating and analyzing multi-protocol service data, a receiving end and a sending end. Background technique [0002] With the rapid development of communication technology and digital technology, users' demands for acquiring and sharing business data resources are becoming more and more urgent and diverse. The business data in data communication and wireless broadcasting usually include stream mode business, file mode business, IP mode business, etc.; and the data of different mode business will be encapsulated differently according to the corresponding mode business before transmission, and transmitted Different treatment is given to the lower layer protocols. [0003] In the existing technology, for different modes of business, the encapsulation and processing methods and processes of business data at the data link layer are different, and it is impossible to u...
