Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a search and discovery model based on multicast. Background Art

[0002] Many application systems in a LAN environment have multiple microservice devices and multiple client devices. Each client needs to search and connect to its associated microservice device, and after pairing, complete the business interaction under independent multicast. If the business multicast address conflicts, it is easy to cause mutual interference between business units.

[0003] Based on this, the present invention designs a multicast-based search and discovery model to solve the above problems. Summary of the invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a search and discovery model based on multicast.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: A multicast-based search and discovery model includes multiple business units, multiple client units, and a local area network; The business unit generates a customer identification code of the customer unit paired with it; The local area network communication connection is provided with a public multicast creation module for public multicast creation for communication between multiple business units and multiple client units; The service unit is used to create a service multicast; The public multicast is used for querying network packets between multiple service units to inquire whether the service multicast is occupied; When a service multicast is occupied by a service unit, it replies to the public multicast with a reply network packet indicating that the service multicast is occupied; When the service multicast is not occupied, the service unit that creates the service multicast sends a joining invitation network packet that records the service multicast address and the client identification code to the public multicast; The public multicast is also used for the client unit to receive a joining invitation network packet and identify whether the client identification code in the joining invitation network packet is paired with it, and when paired, the service unit searches for the service multicast address in the joining invitation network packet; The client unit chooses whether to interact with the user unit for private network data via service multicast.

[0006] Furthermore, the service unit includes a service server, an identity creation module, a service multicast address generation module, a channel occupancy processing module, a service multicast creation module and a communication module; The service server is connected to the identity creation module, the service multicast address generation module, the channel occupancy processing module, the service multicast creation module, and the communication module; The channel occupancy processing module is connected in communication with the service multicast address generation module, and the service multicast address generation module is connected in communication with the service multicast creation module; The service multicast creation module and the communication module are both connected to the local area network communication; The service multicast creation module is used to create a service multicast set on the local area network; The service multicast address generation module is used to generate a service multicast address; The identity creation module is used to create a customer identification code.

[0007] Furthermore, the service server is used to generate a joining invitation network packet recording the service multicast address and the client identification code; The service server is further used to generate an inquiry network packet containing a service multicast address and inquiring whether the address is occupied, and to generate a reply network packet containing a service multicast address and inquiring whether the address is occupied.

[0008] Furthermore, the query network packet is used when the service multicast creation module generates a service multicast, and the communication module sends it to the public multicast once at an interval of ms; The communication module 1 is used for the service server to send and receive network packets to the public multicast and service multicast set on the local area network; The channel occupancy processing module is used for processing and judging the reply network packets.

[0009] Furthermore, the channel occupation processing module compares the service multicast address in the received reply network packet with the service multicast address generated by the service multicast address generation module to see whether they are the same; If they are the same, the channel occupancy processing module sends a service multicast occupancy signal to the service server, and the service server sends a service multicast generation signal to the service multicast creation module; If they are not the same, the channel occupation processing module sends a service multicast available signal to the service server, and the service server sends a joining invitation network packet sending instruction to the communication module.

[0010] Furthermore, the client unit includes a client device, a communication module 2 and a channel search module; The client device is connected to the communication module 2 and the channel search module, and the communication module 2 is connected to the local area network.

[0011] Furthermore, the communication module 2 is used for the client device to send and receive network packets to the public multicast and service multicast set up on the local area network; The client device is used to identify whether the client identification code in the received joining invitation network packet matches; When a match occurs, the client device reads the service multicast address in the joining invitation network packet, and searches for and joins the service multicast through a channel search module.

[0012] Furthermore, the channel search module is also used to select whether to join the service multicast.

[0013] Furthermore, in step one, multiple service servers and client devices join a common multicast; Step 2: randomly generate a service multicast through a service multicast creation module and generate a service multicast address through a service multicast address generation module; Step 3: The service server generates a query network packet and sends it to the public multicast through the communication module once every ms. When the communication module 1 does not receive a reply network packet after the inquiry network packet is sent more than times, the service server determines that the service multicast is not occupied, and the communication module 1 sends a joining invitation network packet to the public multicast; When the communication module 1 receives the reply network packet, the communication module 1 sends the reply network packet to the business server, and the business server sends it to the channel occupation processing module; Step 4: the channel occupancy processing module determines whether the service multicast address in the reply network packet is the same as the service multicast address generated by the service multicast address generation module; If they are the same, the channel occupation processing module determines that the service multicast is occupied, and the channel occupation processing module sends a multicast reset instruction to the service server. The service server sends a multicast reset instruction to the service multicast creation module. The service multicast creation module deletes the service multicast and generates another service multicast, and returns to step three. If they are not the same, the service server determines that the service multicast is not occupied, and the communication module sends a joining invitation network packet to the public multicast; Step 5, when the communication module 1 receives the inquiry network packet, the communication module 1 sends the inquiry network packet to the business server, and the business server sends it to the channel occupancy processing module; Step 6, the channel occupancy processing module compares whether the service multicast address in the query network packet is the same as the service multicast address used by the communication module 1; If they are the same, the business server generates a reply network packet and sends it to the communication module 1, and the communication module 1 sends it to the public multicast; If they are not the same, return to step 5.

[0014] Furthermore, in step seven, the communication module 2 receives a join invitation network packet on the public multicast and sends it to the client device; Step 8, the client device determines whether the client identification code recorded in the invitation network packet matches itself; If there is a match, the client device extracts the service multicast address in the joining invitation network packet and searches through the channel search module.

[0015] Compared with the prior art, the present invention has the following beneficial effects: when the present invention is used, all client units and service units join the same public multicast, and service units perform occupancy inquiries on the service multicasts generated by themselves, thereby avoiding service interference caused by service multicast address conflicts.

[0016] When the present invention is used, the client unit can receive a joining invitation network packet matching with it in the public multicast, and can search and join the service multicast address, thereby performing private network data interaction on the multicast network.

[0017] When the present invention is used, a multicast communication network is set up in a local area network, and network packets can be sent to multiple receivers at the same time without sending a separate piece of data to each receiver, thereby improving the utilization rate of bandwidth.
