Description

Micro service system supporting P2P

Technical Field

The invention relates to the technical field of micro service systems, in particular to a micro service system supporting P2P.

Background

The microservice architecture is a distributed system architecture that suggests to segment traffic into finer-grained services and requires independent deployment of responsibility for each service, high cohesion within the service, low coupling between services, mutual isolation, etc. In addition, a unified API is provided to the outside according to a model for service-oriented business domains. The micro service architecture suggests to disassemble services according to services, and the most appropriate technology can be completely selected to realize specific services, and only the API interfaces provided externally are required to be kept consistent. Since the system can be split into multiple services, when these services are configured, the current practice generally directly deploys the services on the public network (or deploys one-end services on the public network and one-end services on the local area network) to facilitate mutual communication between the services, which has the disadvantage that more money is required, and a large number of services are configured by buying a large number of ip addresses of the public network; a large number of services are deployed in a public network, so that network attacks are easy to find, and the security is poor; when the systems are all placed in a local area network, the system does not have good expansibility (a machine room cannot be built across regions) so as to respond to the requests of a large number of cross-region clients, and therefore, a micro service system supporting P2P is provided.

TRAVERSA L, the STUN server protocol establishes NAT mapping table items of media stream in advance on NAT, and after the network between P2P clients is established, the information exchange of the P2P clients between internal networks is carried out through NAT TRAVERSA L.

Preferably, the network service types supported by the P2P client include an intranet service and a STUN service, wherein the intranet service serves as a basis for establishing contact between the P2P client and serves as an information communication carrier, and the STUN service serves as a control center in an information communication process between the P2P clients.

Preferably, the microservice system where the P2P client is located is deployed in different intranet services, and services not in the same lan are subjected to network penetration through STUN service, so as to realize registration and communication between services.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

STUN's full name Simple traversal over UDP Through Network addresses relays, i.e. Simple traversal over NAT by UDP (Symmetric NAT), client (host provided service within the home Network, compare STUN C L iett) sends a request to STUN SERVER outside NAT according to UDP request protocol, the request message continues forwarding the translated Address after reaching NAT, STUN SERVER receives the request message, generates a response message carrying the source port number of the request message (i.e. the port number on which STUN C L iett communicates outside on NAT) and then sends the response message to STUN C L iett Through NAT, STUN C L iett knows its corresponding external Address on NAT by the content in the response message body and fills it in the UDP load of the later call protocol, the opposite end, and also can register this translated Address directly at the terminal, thus solving the problem of traversal over mgc NAT and media stream mapping on the NAT.

Referring to fig. 1-2, the present invention provides a technical solution, wherein a P2P-supporting microservice system includes a P2P client 1, an intranet server 2, a ROUTER 3, a STUN server 4 and a trasversa L5, a UDP request protocol is used as a communication protocol of the microservice system, the STUN server 4 filters and forwards the communication protocol uniformly, and supports the P2P client 1 to send directly through the trassa L5, the STUN server 4 establishes a NAT mapping table entry of a media stream in advance on a NAT, and the specific component contents are:

STUN server 4: the STUN server 4 is a control center of a micro service system supporting the P2P, all request messages are detected and distributed by the STUN server 4, when entering the network, the P2P client 1 needs to perform request registration in the STUN server 4, after the registration is passed, the P2P client 1 information registered by the P2P client 1 is stored in a memory of the STUN server 4, and the functions of establishing information exchange and modifying conversation between the P2P clients 1 are achieved in the system;

the P2P client 1 joins the network of the STUN server 4, one P2P client 1 is used as a service site of the STUN server 4 to carry out information transmission with another P2P client 1, and when the detection information passes, the P2P client 1 joins the STUN server 4 site and carries out TRAVERSA L5 direct information transmission;
