Description
Technical Field
The invention relates to the field of network communication, in particular to a data transmission method based on hardware acceleration, a device and a processor thereof.
Background
At present, many router gateways support VPN dialing, and a Virtual Private dial Network (VPN) refers to accessing a public Network by using a dialing function of the public Network (such as ISDN or PSTN) to implement a Virtual Private Network, thereby providing access services for enterprises, small ISPs, mobile office staff, and the like. Common VPN protocols include both PPTP and L2TP, which are IP packets transmitted through a public network (e.g., the Internet) using VPN encapsulation (PPTP or L2TP), where fig. 1(a) is a schematic diagram of PPTP protocol packet encapsulation according to the prior art, and as shown in fig. 1(a), a packet under the protocol may include: a public network IP head, a GRE protocol head, a PPP head and an internal network IP head; fig. 1(b) is a schematic diagram of the encapsulation of a L2TP protocol packet according to the prior art, and as shown in fig. 1(b), a packet under the protocol may include: a public network IP header, an L2TP protocol header, a PPP header, and an intranet IP header. The configuration is based on a point-to-point tunneling protocol (PPP) VPN solution. VPN provides an economical and efficient point-to-point connection between a remote user and a private enterprise network, and with the continuous increase of network bandwidth, the requirements on VPN delay and performance are higher and higher.
Fig. 2 is a schematic diagram of a forwarding path with a hardware acceleration engine according to the prior art, and as shown in fig. 2, when a router forwards a data packet, NAT conversion is required, and the conversion is generally implemented in a network protocol stack and mainly performed by a CPU, so that a Linux kernel consumes a large amount of CPU resources when performing NAT conversion, which further causes delay increase and performance limitation. In order to reduce the CPU load, reduce the delay, and improve the performance, a Hardware acceleration Engine is generally designed outside the CPU, and the NAT translation work in the protocol stack is handed over to the Hardware acceleration Engine (Hardware NAT Engine, abbreviated as HWNAT).
However, a general acceleration engine only supports simple protocols such as IP, IPv6, and PPoE, and cannot accelerate complex VPN tunneling protocols such as PPTP and L2 TP. For router VPN dialing, when the router forwards, it needs to perform NAT conversion on the intranet IP header, then adds the corresponding VPN protocol header information, and then adds the public network IP header to send out. The VPN protocol is relatively complex, so that a general router does not support VPN protocol acceleration although the general router has a hardware acceleration engine, the VPN dialing transmission rate is low, the time delay is large, and the network experience is poor.
Moreover, a general hardware acceleration engine supports protocols such as IP, PPPoE, IPv6, and the like, and cannot accelerate complex VPN protocols such as PPTP and L2 TP. The hardware acceleration engine capable of supporting the PPTP and the L2TP protocol is also provided, such acceleration engine needs to be capable of parsing and understanding the PPTP and L2TP protocols, the hardware design is complex, the cost is much higher than that of a general hardware acceleration engine, the expansibility is not good, and the hardware acceleration engine may need to be redesigned if a new VPN protocol is to be supported. For example, the related art provides an accelerated access method based on PPTP VPN, which requires a second server cluster supporting GRE protocol connected between a first server and a VPN server, that is, an acceleration server is added for acceleration.
In view of the above problems in the related art, no effective solution has been proposed at present.
