Service-oriented IPv6 address specification and distribution method, terminal and system for implementing the same

Abstract

The present invention relates to IPv6 address class facing business as well as distributing method, corresponding system frame and user terminal. The method includes: dividing the IPv6 address to network address and business address; classing the business address further according to the business provided by telecommunication, so as to form a plurality of addresses relative to various businesses. Wherein, distributing network address to user terminal; distributing business address to various business client of user terminal, the business client applies the business address of its business to operator address management server according to business address apply and distributing protocol, then taking the business address as the source address of communication of client. According to the present invention, it is easy to implement the function of business statistics, user tracing to the source as well as data redirection, and to establish transparent server quality acceptance and realization mechanism between the operator and users, also the management and control to internet of operator is more convenient and efficient.

Description

technical field [0001] The present invention relates to the subfield of data communication in the technical field of telecommunication, in particular, the present invention relates to a method for classifying and assigning IPv6 addresses oriented to telecommunication services, and a terminal and a system for realizing the method. Background technique [0002] In the current IPv4 network, the trend of many service applications based on IP network integration is becoming more and more obvious, and IP technology has gradually become a broad and general network bearer platform. The economy, flexibility and ability to support multiple services of IP are unmatched by the original circuit switching network. However, the IP network also encountered some problems in the development process. Due to the lack of IP addresses, the traditional IP network generally assigns one IPv4 address to a terminal, and sometimes only assigns a public IP address to multiple terminals. This public IP ...

AI Technical Summary

Problems solved by technology

After the service data flow sent from the user terminal reaches the network edge router, the IPv4 network needs to conduct in-depth analysis on the transport layer (TCP or UDP (User Datagram Protocol, User Datagram Protocol)) port or even the application layer data protocol to determine the service it belongs to. Type, due to the dynamic changes of ports in the transport layer and the diversity of application layer protocols, it is currently difficult to accurately identify business flows

Secondly, in-depth analysis of data packets increases the processing overhead of network edge devices, affects device performance, and reduces data transmission quality

In the IPv4 network, the method of classifying the data flow based on the source and destination IP addresses is also adopted, but since the address space of the IPv4 network is not classified according to the service, it is difficult to determine the service flow according to the IPv4 address category, unless in the routing The table indicates that a certain address segment serves a specific service, but this will increase the capacity of the routing table and cause many problems for network organization and management

Another method of business flow identification is based on network physical ports. This method classifies all data flows sent from this physical port into one category. However, the granularity of business flow identification in this method is too coarse to detail the upper-layer services. Classification

[0006] 2) Since the ToS (Type of Service, service category) field is easy to be modified, it is unreliable to provide differentiated services based only on the ToS field

[0009] At present, when a telecom operator signs a service level agreement (SLA) with a customer, it stipulates the commitment of the operator's network to provide services for the customer, and specifies it in the form of specific index parameters, such as network RTT (Round-Trip Time, loop Time), time, jitter, and network availability, but these definitions are mainly for customers, and are not refined to target different services within customers, so the granularity is relatively coarse

[0010] 4) It is difficult to realize the service quality guarantee of bidirectional data flow including reverse data flow

For the reverse data flow, that is, the data flow sent by the communication peer to the customer, it is difficult to achieve the QoS processing corresponding to the customer's SLA level, mainly because the access segment where the communication peer is located is located at the far end , it is difficult to know the SLA level of the client, so it is difficult to guarantee its service quality

[0012] 5) It is difficult to implement business-oriented data flow routing in the network

Currently, IPv4 data packets do not contain service class information, so service-oriented routing cannot be realized simply by destination IPv4 address

Another method is to analyze the transport layer and application layer information of the data packet. This problem is consistent with the essence of problem 2 and will bring many problems

[0014] 6) Illegal traffic is difficult to identify and track, and it is difficult to restrict

[0015] In the current IPv4 network, illegal traffic including illegal P2P and self-operated services of telecom operators use the same IP address space, and due to the disorder of global IPv4 address planning, it is difficult to use IP addresses in the network for specific The legality of IP packets is judged, which has resulted in the current situation where various illegal traffic occupies most of the network resources of network operators, but they are helpless

[0016] In short, building a high-quality IP bearer network that supports multiple telecommunication services based on the IPv4 protocol will encounter various problems. One of the core reasons for these problems is the disorder of IPv4 address space planning, and the IP The address does not contain service category information, so after any IP packet arrives in the network, it is difficult for the network device to judge the service category of the IP packet, so it is difficult to make consistent processing with the service category at the network level
