All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, are intended to fall within the scope of the present invention.
Example 1
As shown in FIG. 1, the equipment batch upgrading method of the invention comprises the following steps:
s1: the service end sends the broadcast of the upgrading equipment to the local area network;
s2: the equipment end analyzes the received broadcast packet and judges whether the received broadcast packet meets upgrading conditions;
s3: if the upgrading conditions are met, the equipment end obtains an upgrading image from the server end through the TFTP;
s4: and after the equipment end is upgraded, sending a message of successful upgrading to the server end.
According to the method, the service end (PC end) sends the broadcast of the upgrading equipment to the local area network, the equipment end (client end) analyzes the received broadcast packet, and then the equipment in the network is upgraded in batches, so that the network section of the equipment is not required to be known, and the upgrading efficiency is improved.
In the step S1, the broadcasting carrying information includes:
upgrade feature code (e.g., 0 xaaa), model number of the device to be upgraded, upgrade image name, size of upgrade image, MD5 value of upgrade image, etc.
And sending three broadcasts to inform the equipment to be upgraded in the local area network, and receiving the information to indicate that the equipment is to be upgraded, and judging whether the equipment meets the upgrading conditions or not through the information carried by the broadcasts.
The step S2 specifically includes the following steps:
the equipment end analyzes the received broadcast packet and judges whether the received broadcast packet meets upgrading conditions or not through upgrading feature codes;
if the upgrade feature code is not identified, filtering the information;
if the upgrading feature code is identified, judging whether the upgrading condition is met or not by comparing the information in the package.
If the upgrading feature code is identified, judging whether the upgrading feature code meets upgrading conditions or not by comparing the information in the package, and specifically comprising the following steps:
judging whether the model of the equipment to be upgraded is consistent with the equipment, whether the name of the upgrade image is correct, whether the size of the upgrade image is consistent with the size of the upgrade image, and the like;
if one or more items do not accord with the information, filtering the information;
if both are met, step S3 is entered.
Analyzing the broadcast packet, and specifically judging whether the equipment end accords with the upgrading conditions or not through the information in the packet; the equipment in the network is upgraded one by one, the equipment is optimized to be upgraded in batches, and equipment with different models can be upgraded in batches through upgrading feature codes and the models of the equipment to be upgraded.
The step S3 specifically includes the following steps:
when the upgrade condition is met, the equipment end obtains an upgrade image from the server end, the IP of the server end and the name of the upgrade image are analyzed through the broadcast received in the step S2, and the tftp command is used for obtaining the upgrade image from the server end.
If the upgrade condition is met, the equipment side can pass the command: the tftp-p-l file name IP obtains the upgrade image file.
Wherein, the step S3 further includes the following steps:
if the tftp command is used for acquiring the upgrade image from the server, the upgrade image is acquired again, and if the upgrade image is not acquired successfully after 3 times, an upgrade failure message is sent to the server.
After the upgrade failure message is sent to the server, the method further comprises the following steps:
if the service end receives the upgrade failure message, the service end clicks on the upgrade again, and the upgrade image file is actively sent to the equipment end, so that the equipment end performs the upgrade again.
Generally, if the upgrade fails, the upgrade can be manually performed at the service end point to perform the upgrade again, and the upgrade image file is actively sent to the device end, so that the device end performs the upgrade again.
Wherein, before the step S4, the method further comprises the following steps:
the device side verifies the MD5 value of the upgrade image.
The verification of the MD5 value is performed to ensure that the upgrade image is correct.
MD5 action:
1. preventing tampering. 1) For example, an electronic document is sent, before sending, the output result a of MD5 is obtained, and then after the counterpart receives the electronic document, the counterpart also obtains the output result b of MD5. If a is the same as b, the middle part is not tampered; 2) For example, providing file downloading, in order to prevent lawbreakers from adding Trojan horse in an installation program, MD5 output results obtained by installing the file can be published on a website; 3) The SVN also uses MD5 after detecting whether the file was modified after CheckOut.
2. Preventing direct visibility of the plaintext. At present, many websites store the MD5 value of the user password when the database stores the user password, so that even if a lawbreaker obtains the MD5 value of the user password of the database, the user password cannot be known. For example, in the UNIX system, the user's password is encrypted by MD5 (or other similar algorithm) and stored in the file system, when the user logs in, the system calculates the password input by the user as MD5 value, and then compares the MD5 value with the MD5 value stored in the file system to determine whether the input password is correct. Through the steps, the system can determine the legality of the user logging in the system under the condition that the clear code of the user password is not known, so that the user password can be prevented from being known by the user with the authority of the system administrator, and the difficulty in cracking the password is increased to a certain extent.
3. Preventing repudiation (digital signature). This requires a third party certification authority. For example, user a writes a file, the certification authority generates and records digest information on the file by using the MD5 algorithm, and if user a later says that the file is not written by him, the authority only needs to regenerate the digest information on the file, and then compares the digest information recorded in the album with the digest information recorded in the album, and if the digest information is the same, the digest information is proved to be written by user a, which is called a digital signature.
The device side checks the MD5 value of the upgrade image, and specifically includes the following steps:
and the equipment end compares the MD5 value of the upgrade image carried in the previous broadcast with the MD5 value calculated by the upgrade image file obtained in practice, and if the MD5 value is consistent with the MD5 value, the step S4 is entered.
Algorithm principle of MD 5:
a brief description of the MD5 algorithm may be: MD5 processes the incoming information in 512-bit packets, each packet is divided into 16 32-bit sub-packets, after a series of processing, the output of the algorithm consists of four 32-bit packets, and after concatenating the four 32-bit packets, a 128-bit hash value is generated. The algorithm is common and mature, and is equivalent to a tool, and can be directly called.
In this way, the method in this embodiment sends the broadcast of the upgrade device to the lan through the server (PC), and the device (client) parses the received broadcast packet, so as to upgrade the devices in the network in batches, without knowing what network segment the device is in, thereby improving the upgrade efficiency.

the server side is used for sending the broadcast of the upgrading equipment to the local area network;
the equipment end is used for analyzing the received broadcast packet and judging whether the received broadcast packet meets the upgrading conditions or not; if the upgrading conditions are met, the equipment end obtains an upgrading image from the server end through the TFTP; after the upgrade is finished, a message of successful upgrade is sent to the server.
In this way, the system in this embodiment transmits the broadcast of the upgrade device to the lan through the server (PC), and the device (client) parses the received broadcast packet, so as to upgrade the devices in the network in batches, without knowing what network segment the device is in, thereby improving the upgrade efficiency.
