Problems solved by technology

[0005] In the process of realizing the present invention, the inventors found that the existing methods for identifying network service types have at least the following disadvantages: to identify the service type corresponding to the message in the form of quintuple, it needs to be included in the entry of the full flow table Save the information of the quintuple, so it needs to occupy more storage space

[0028] As shown in Figure 1, the first embodiment of the method for identifying the service type corresponding to the message provided by the present invention includes:

[0029] Step 101, extracting the network address and port pair of the message;

[0030] In actual situations, many services belong to client / server applications, only some hosts are providing services, and other hosts are clients requesting services, and the business flows related to the hosts providing a certain service belong to the same business type , so the business flow can be recorded by marking the service host; furthermore, many applications often use fixed ports to provide external services. Although these ports may not be standard designated ports, they are fixed for a period of time; During this period of time, all traffic related to the service port belongs to the same business type, so after it is determined that a certain host provides a certain type of service on a specific port, all traffic r...

Abstract

The invention relates to network technology, and discloses a method and device for identifying a service type corresponding to a message, wherein the method for identifying the service type corresponding to a message includes: extracting the network address and port pair of the message; Including the entry of the network address and port pair, the association table stores the entry of the corresponding relationship between the network address and port pair and the service type; if the network address and port are found in the preset association table For an entry, determine that the service type corresponding to the message is the service type indicated by the entry. By using the technical solution provided by the embodiment of the present invention, the service type corresponding to the message can be identified without using the quintuple, and better storage characteristics can be provided.

Description

technical field [0001] The invention relates to network technology, in particular to a method and device for identifying a service type corresponding to a message. Background technique [0002] Nowadays, various applications carried on the network are complicated, and service providers continue to launch new services to attract users. For operators, in order to retain old users and continuously develop more users, it is necessary to ensure that the operating network can It can well carry various key services (such as enterprise resource planning ERP, remote database access, etc.), while restricting the unrestrained occupation of network resources by some non-critical services (such as unsupervised VoIP, peer-to-peer P2P, etc.). On the other hand, the network environment is facing unprecedented security risks, and various malicious attacks and illegal applications emerge in an endless stream, causing immeasurable losses to operators and network users. Therefore, operators ne...
