Problems solved by technology

However, using this method requires adding qos hardware to the network equipment without qos function, which increases the cost
And this method still allocates a large amount of bandwidth for advanced users when the traffic is low, resulting in a waste of bandwidth

Embodiment Construction

[0020] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0021] Such as figure 1 As shown, a kind of Ipsec forwarding method of the present invention comprises the following steps:

[0022] A: Increase the service priority level for each specific data item in the SPD database and SADB database;

[0023] B: Prioritize processing of data items with high priority according to the service priority.

[0024] In step B, the cpu obtains the SPD or SADB data item corresponding to the message that needs to be encrypted and decrypted, and then adds the data item that needs to be encrypted / decrypted to the predetermined encryption and decryption queue according to the service priority. Specifically, it is realized through the following ...

Abstract

The invention discloses a method for forwarding internet protocol security (IPSec) and relates to the technical field of network security. The method comprises the following steps of: A, adding a service priority level to each specific data item in a security policy database (SPD) and a security association database (SADB); and B, according to the service priority level, performing priority processing on high-priority data items. The method for forwarding the IPSec has the advantages that: according to the situation of network flow and the size of the priorities of users, the bandwidths of the users with different priorities are dynamically changed; by improving the bandwidth distribution of high-priority users, using experiences of the high-priority users are improved; installation of quality of service (QoS) equipment is not required for network equipment without a QoS function; and cost is reduced.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to an Ipsec forwarding method. Background technique [0002] IPSec (Internet Protocol Security) is a set of protocols defined by IETF (Internet Engineering Task Force) that provides Internet Protocol (IP) security at the network layer. It ensures data transmission through data encryption, authentication, and integrity checks. Reliability, privacy, confidentiality. It consists of a series of RFC documents, among which RFC2401 defines the basic structure of IPSec; RFC2402 defines the Authentication Header (AH) of IPSec; RFC2406 defines the Encapsulating Security Payload (ESP) of IPSec; RFC2409 defines the Internet Key Exchange (IKE) of IPSec. [0003] IPSec protocols include: AH, ESP, IKE, etc. ESP encapsulates security payloads to provide data encryption and verification functions for IP payloads. The AH authentication header provides data integrity and verification funct...
