Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the structural diagram of the IP packet load part is described below.

[0029] Such as figure 1 As shown, the first three bytes are SSL handshake message type (0x16) + protocol version number (0x030x02);

[0030] The next 43 bytes include:

[0031] a) The length of 2 bytes, specifically the length of the handshake packet;

[0032] b) 1-byte type identification (01 means ClientHello message);

[0033] c) The length of 3 bytes, specifically the length of the ClientHello message;

[0034] d) 2-byte version number;

[0035] e) A random number of 32 bytes;

[0036] f) The first byte in the last 3 bytes is the length identification bit of the algorithm suite;

[0037] g) The algorithm suite type of length, each type is 2 bytes

[0038] 3) The length range to be searched does not exceed f) the length of the sub-item

[0039] Such as figure 2 As shown, the first three byte...

Abstract

The invention provides a load distributing method based on a secure socket layer protocol characteristic. The method comprises the following steps: S1, acquiring an IP data packet from a network; S2, analyzing and storing head information of the IP data packet; S3, judging whether the IP data packet is SSL (secure sockets layer) protocol data or not, if yes, executing the step S4, otherwise, finishing the process; S4, acquiring an algorithm suite type of an IP packet load part of the IP data packet; S5, structuring different load distributing strategies according to different algorithm suite types. Compared with the prior art, the load can be distributed without decoding the transport layer security / secure socket layer (TLS / SSL) data packet. Load distributing strategies are dynamically structured by using the characteristics of the transport layer security / secure socket layer (TLS / SSL) data packet, and the load distributing method is high in distributing efficiency and safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of computer networks, and in particular relates to a load distribution method based on the characteristics of the secure socket layer protocol. Background technique [0002] With the rapid growth of Internet users, the speed of obtaining information has become an important factor restricting the development of the Internet. Due to the increase of business volume, the rapid growth of access volume and data flow of each core part of the existing network, its processing capacity and calculation intensity also increase correspondingly, making it impossible for a single server device to bear it. [0003] Load balancing is to balance the load (working tasks) and distribute them to multiple operating units for execution, such as Web servers, FTP servers, enterprise key application servers and other mission-critical servers, so as to jointly complete the work tasks. [0004] Usually, load balancing is divided accor...
