Abstract

The embodiment of the invention discloses a message encapsulation method and device, and a message decapsulation method and device. The message encapsulation method includes: generating message header information of a predetermined length; splicing data of a predetermined length at the beginning of the original message to the end of the original message; covering the beginning of the original message with the generated message header information data of a predetermined length. The message encapsulation method and device, and the message decapsulation method and device provided in the embodiments of the present invention reduce data copying in the process of message encapsulation and decapsulation, and improve the efficiency of message encapsulation and decapsulation.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a message encapsulation method and device, and a message decapsulation method and device. Background technique [0002] A virtual private network (Virtual private network, VPN) refers to a logical virtual subnet formed by connecting physically distributed networks in different locations through a public network. It uses authentication, access control, confidentiality, and data integrity security mechanisms to build a private network on the public network, so that data can be transmitted in the public network through a secure "encrypted pipeline". [0003] Packet encapsulation is a key technology in virtual private network. By encapsulating the packets to be transmitted, a virtual pipeline can be established between nodes on the public network, thereby building a private network on the public network. [0004] Existing packet encapsulation technologies mainly include L...
