Technical Field
The invention relates to the technical field of data communication equipment, in particular to a method for upgrading data terminals in batches based on an optical network.
Background
With the development of the communication industry, data communication (digital communication for short) terminal products (PON, CM, WIFI, IPTV, etc.) have a requirement for batch upgrade during manufacturing, warehousing and after-sale of terminals, and there is a situation that one hardware state corresponds to a plurality of custom software. In order to improve the production efficiency, save the cost and reduce the development workload of production testing software, production is carried out in a software and hardware separation mode by production enterprises, namely, the production software is firstly used for completing hardware manufacturing and performance index testing, then the software is upgraded into custom software, and finally parameter verification is carried out. The existing batch upgrading mainly adopts a mode of a plug flow server and a switch, and the whole link adopts Ethernet transmission. The stream pushing server pushes the upgrading multicast stream, and the upgrading data reach the data terminal to be upgraded through the switch. At present, most of data terminal multicast upgrading is realized in a boot, fixed multicast addresses and ports are monitored, and the multicast addresses and the ports monitored by different types of products of the same manufacturer are often the same, so that upgrading data of data products cannot be transmitted in the same network. Due to the same limitation of Ethernet transmission distance and the same limitation of different types of data terminals in monitoring multicast address ports, a stream pushing server and a switch must be deployed for each production line in the production process. Thereby causing the problems of high cost, no unified management, inflexible procedure adjustment and the like.
Disclosure of Invention
The invention aims to provide a method for upgrading data terminals in batches based on an optical network, which is used for solving the problems that in the prior art, due to the same limitation of Ethernet transmission distance and the monitoring of multicast address ports by different types of data terminals, a stream pushing server and an exchanger must be deployed for each production line in the production process, the cost is high, unified management cannot be realized, and the process adjustment is inflexible.
The invention solves the problems through the following technical scheme:
a method for upgrading data terminals in batches based on an optical network comprises the following steps:
step S1: the stream pushing server maintains and manages the upgrade data, and pushes a plurality of multicast streams to the optical receiving terminal, wherein the multicast streams comprise service description streams and upgrade streams, the service description streams describe the related information of the upgrade streams, and the upgrade streams are the multicast upgrade data defined by manufacturers; adding a multicast address translation TransAddr field in the service description stream for upgrading the translation of the stream multicast address and the port;
step S2: the optical receiving terminal analyzes the multicast stream, analyzes the service description stream data, the user selects the corresponding multicast stream according to the service description stream and the type of the data terminal corresponding to the optical receiving terminal, the optical receiving terminal completes the conversion of the multicast address and the port of the upgrading stream according to the multicast address conversion TransAddr field of the service description stream in the selected multicast stream, and forwards the upgrading stream to the data terminal;
and step S3: and the data terminal finishes upgrading according to the received upgrading flow.
And the data message of the service description stream is packaged in a UDP layer, the data message of the service description stream comprises an identifier, a data packet number, a data length and a data field, and the data field is packaged in a json format and comprises push stream server information, equipment type and upgrading multicast stream information.
The flow pushing server sends the multicast flow to the optical exchanger, and the optical exchanger converts the multicast data into optical signals and sends the optical signals to the optical receiving terminal through the optical splitter.
Compared with the prior art, the invention has the following advantages and beneficial effects:
the invention is not limited by the product type and the manufacturer of the data terminal, the data terminal only needs to support the multicast upgrading function without independent customization and development, and can simultaneously carry out batch upgrading on different types of data terminals through one set of system, thereby having the advantages of low cost, flexible arrangement, convenient extension, unified management and planning, and the like.

Detailed Description
The present invention will be described in further detail with reference to examples, but the embodiments of the present invention are not limited thereto.
Example 1:
with reference to fig. 1 and fig. 2, a method for upgrading data terminals in batches based on an optical network includes:
step S1: the stream pushing server maintains and manages the upgrading data, a plurality of multicast streams are pushed to the optical switch, the optical switch converts the multicast data into optical signals and then sends the optical signals to the optical receiving terminal through the optical switch, the multicast streams comprise service description streams and upgrading streams, the service description streams describe the relevant information of the upgrading streams, and the upgrading streams are the multicast upgrading data defined by manufacturers; adding a multicast address translation TransAddr field in the service description stream for upgrading the translation of the stream multicast address and the port;
referring to fig. 3, the data packet of the service description stream is encapsulated in the UDP layer, the data packet of the service description stream includes an identifier, a data packet number, a data length, and a data field, and the data field is encapsulated in a json format and includes information of a push streaming server, a device type, and information of an upgraded multicast stream.
For example, the service description data is as follows:
step S2: the optical receiving terminal analyzes the multicast stream, analyzes the service description stream data and displays the data through the web, a user selects the multicast stream to be forwarded through the web according to the service description stream and the type of the data terminal corresponding to the optical receiving terminal, the optical receiving terminal completes the conversion of the multicast address and the port of the upgrading stream according to the multicast address conversion TransAddr field of the service description stream in the selected multicast stream and forwards the upgrading stream to the data terminal through the Ethernet; on the premise of ensuring that the address and the port of the converted upgrading stream are not conflicted, the optical receiving terminal can forward a plurality of upgrading streams to upgrade different types or the same type of equipment to be upgraded.
