Compared with the prior art, the beneficial effects of the present invention are:

1. Compress the fixed interactive content into a static dictionary, which is stored in the server and the router respectively, forming a common agreement between the server and all the routers; compressing the content that needs to be dynamically set into a dynamic dictionary, forming a relationship between the server and a specific router The convention; the static dictionary and the first dynamic dictionary generally each index represents a key-value pair, so that when the message is sent, the index can be used instead of the original plain text for transmission, saving bandwidth. When the router receives the SOAP packet, it will determine the composition of the SOAP packet after parsing. If the SOAP packet is composed of the index in the first dynamic dictionary and/or the static dictionary, the index is searched in the dictionary. The encoded information of the representative is reorganized to form a complete uncompressed message, and the operation is performed according to the meaning of the message. The originally transmitted plain text SOAP message is replaced by the corresponding index, and the transmitted content is greatly reduced, and does not occupy a large amount of bandwidth.

2. The router determines that there is no index of the second dynamic dictionary, the first dynamic dictionary, and the static dictionary in the received SOAP message, indicating that the SOAP message cannot be replaced by the index in the dictionary, and is composed of plain text, that is, They are all composed of encoded information. Without compression, the router can directly perform operations based on the content represented by the encoded information.

3. When the index of the second dynamic dictionary exists in the SOAP message, the index of the second dynamic dictionary is first parsed, and becomes the index in the first dynamic dictionary and/or static dictionary represented by the latter. Further judgments are provided to provide the basis.

4. When a SOAP message is composed of a mixture of partial index and coded information, it will be reorganized according to the content and coded information represented by the index part to form a complete message, and then the operation is performed according to the complete message. The part of the index compresses the size of the message, saving a portion of the bandwidth and increasing the transfer speed.

5. When all the SOAP messages are composed of the encoded information, after performing the operation, the encoded information is judged, and the encoded information capable of forming the key-value pair is updated into a corresponding new index into the first dynamic dictionary. When it is convenient to send the same content again, it can be replaced by the index; when the SOAP message is composed of the mixed information and the index, after the operation is performed, it is determined whether the encoded information and the index can form a key-value pair, and , judging purely encoded information is Can it be composed of key-value pairs, if possible, each key-value pair of the composition is updated into a new index into the first dynamic dictionary, and when the same content is sent again, the index can be replaced by this index, and SOAP is compressed. The size of the message is used to save bandwidth.

6. A complete SOAP message is divided into three parts, an envelope element (Envelope), a header element (Header), and a body element (Body). Each element also contains a different number of key-value pairs. When the SOAP messages are all composed of indexes, that is, the key-value pairs in each element are replaced by indexes, and a new index is formed to the second dynamic dictionary for the index combination in each element, that is, each new index represents a certain The index combination of the elements. When the content of the same element is sent next time, it can be directly replaced by the index in the second dynamic dictionary, which is smaller than the message replaced by the index in the first dynamic dictionary and/or the static dictionary, which greatly improves the number of messages. The compression ratio reduces the occupation of the network.

7. Before sending the message, the server will first retrieve whether the content of the message can be replaced by the index in the dictionary. If possible, replace it with an index, compress the size of the message, and save bandwidth.

The SOAP message transmission method and system of the present invention greatly compresses the size of the SOAP message through the agreed dictionary between the router and the server, reduces the network occupation rate, and improves the user experience.

detailed description

In order to more clearly illustrate the embodiments of the present invention or the technical solutions of the prior art, the specific embodiments of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings in the following description are only some embodiments of the present invention, and those skilled in the art can obtain other drawings according to the drawings without obtaining creative labor, and obtain Other embodiments.

In order to simplify the drawings, only the parts related to the present invention are schematically shown in the drawings, and they do not represent the actual structure of the product. In addition, in order to make the drawings simple and easy to understand, components having the same structure or function in some of the figures are only schematically illustrated, or only one of them is marked. In the present context, "a" means not only "only one" but also "more than one".

In an embodiment of the present invention, as shown in FIG. 1, a SOAP message transmission method includes: Step S10: A router receives a SOAP message sent by a server, where the SOAP message includes an envelope element, a header element, and a body element, and an envelope The element, the header element and the body element each include at least one key value pair; the step S20 router parses the SOAP message; and the step S50 the router retrieves whether the SOAP message is all the index in the first dynamic dictionary and/or the static dictionary stored in the router. If yes, step S60 is performed; in step S60, the router reorganizes the content indicated by the index, and performs an operation according to the reorganized content.

Specifically, the static dictionary and the dynamic dictionary constitute a dictionary, and the dynamic dictionary includes a first dynamic dictionary and a second dynamic dictionary.

A complete SOAP message is divided into three parts, namely the envelope element (ENV, Envelope), the header element (Header) and the body element (Body). The following is an example of the ENV part:

This mainly describes the use environment, coding method, coding scheme, etc. These are the most commonly used, and generally do not change, so you can create a static dictionary for these fixed key-value pairs, see Table 1 below. In the Header and Body sections of a SOAP message, most of the key-value pairs are generally invariant, but the values are changed, as in the Header section of the SOAP message below:

<SOAP-ENV:Header>

<cwmp:ID SOAP-ENV:mustUnderstand="1">24758</cwmp:ID>

</SOAP-ENV:Header>

This part mainly marks the ID of the message. Although the content of the ID will change, except for the part of "24758", other parts generally do not change. Therefore, the static dictionary can be further extended, see Table 2 below.

Table I

Table II

In summary, the static dictionary consists of two parts: 1) for a completely fixed key-value pair, it can be straight Use an index representation; 2) For key-fixed key-value pairs, you can use a fixed key to represent it.

In the simplest case, the key-value pairs are in the dictionary. You only need to use one byte to represent the entire key-value pair, as shown in Table 3 below. The leftmost one is fixed to 1, indicating that the key-value pair is in the dictionary, and the last 7 digits. Stores the index of the key-value pair in the dictionary. E.g:

Xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"

Xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"

Xmlns:xsd="http://www.w3.org/2001/XMLSchema"

Xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Xmlns:cwmp="urn:dslforum-org:cwmp-1-0"

Such a bunch of key-value pairs, according to the previously defined dictionary, can be expressed as follows:

1000 0001------- (indicating that the key-value pair is in the dictionary, the index value is 1)

1000 0010------- (indicating that the key-value pair is in the dictionary, the index value is 2)

1000 0011------- (indicating that the key-value pair is in the dictionary, the index value is 3)

1000 0100------- (indicating that the key-value pair is in the dictionary, the index value is 4)

1000 0101------- (indicating that the key-value pair is in the dictionary, the index value is 5)

Through actual comparison, it can be seen that the content that needs to be represented by tens of hundreds of bytes is now only required to be 5 bytes, and the SOAP message is greatly compressed during the transmission process, thereby reducing the bandwidth occupation.

Table 3

When the key is in the dictionary, and the value is not, you need to use static Huffman coding to encode the value. You can use a large number of interactive messages to train the Huffman tree to make it fit the actual situation of the interactive message. The maximum compressed message size is reached.

Huffman coding uses a variable length coding table to encode a source symbol (such as a letter in a file). The variable length coding table is obtained by evaluating the probability of occurrence of the source symbol. Encoding, if the probability of occurrence is low, the longer encoding is used, which reduces the average length and expected value of the encoded string, thus achieving the lossless compression number. According to the purpose. Huffman coding is used here to enable previously frequent messages to be transmitted with shorter coded information, so that the size of the message transmitted between the server and the router is better compressed.

For specific applications, please refer to Table 4 below. The first position of the first byte is 0, indicating that the value is not in the dictionary. The following Index is the index of the key in the dictionary, and the second byte is used to indicate the length of the value. Value. It should be noted here that since the Huffman coding is used for the variable length coding, the length of the value needs to be in bits, one byte, that is, 8 bits.

Table 4

such as:

<cwmp:ID SOAP-ENV:mustUnderstand="1">24758</cwmp:ID>

The key in the above encoded information belongs to the index in the dictionary, and the value is not, then after the first transmission of the SOAP message, the above key value pair can be added to the first dynamic dictionary, see Table 5 below. The next time you send this code, you can directly use the index in the first dynamic dictionary instead, 1000 0111------- (indicating that the key-value pair is in the dictionary, the index value is 7), compared to the first The need for 7 bytes of content, this time only requires 1 byte; compared to the case of not using compression, the degree of compression is much better.

Table 5

Both the router and the server store the same dictionary. When the SOAP message is transmitted, the two parties can analyze the contents of the index without any problem, and reorganize according to the contents of the indexes, so as to obtain a complete plain text SOAP message. Then proceed according to the content of this message. In general, static dictionaries exist for fixed content. Therefore, the content of static dictionaries is agreed between the server and all routers, that is, the server and all routers are stored in static. The content of the state dictionary is the same; the dynamic dictionary is generated according to the content of the interaction between the server and the router. Because the content of the interaction between the server and each router is different, the content of the dynamic dictionary is also different, that is, the dynamic dictionary is a server and some A common convention between specific routers.

Preferably, the step S20 and the step S50 further comprise: step S30: the router retrieves whether the SOAP message has an index of the second dynamic dictionary stored in the router, and if not, performs step S40; and the step S40 searches whether the SOAP message is retrieved by the router. There is an index of the first dynamic dictionary and/or the static dictionary stored in the router. If yes, step S50 is performed. If not, step S80 is performed; and step S80 performs an operation according to the content indicated by the encoded information in the SOAP message. .

Preferably, step S30 further includes: the router retrieving whether the SOAP message has an index of the second dynamic dictionary stored in the router, and if yes, performing step S31; and step S31, the router parsing the index of the second dynamic dictionary existing in the SOAP message And obtaining the content represented by the index of the second dynamic dictionary; wherein the content represented by the index of the second dynamic dictionary includes an index of the static dictionary, and/or an index of the first dynamic dictionary.

Specifically, the second dynamic dictionary is a secondary compression performed when most of the messages become part of the dictionary. For example, the SOAP message is:

Although 5 bytes of content are used instead of hundreds of bytes, there is room for optimization in this part. These 5 bytes can also generate a second dynamic dictionary, generating a new dynamic dictionary index "8" to represent This collection of 5 bytes:

1000 1000-------- (indicating that the key-value pair is in the dictionary, the index value is 8)

Such a byte to represent the original hundreds of bytes of content, greatly improving the compression ratio and reducing the occupation of the network. Therefore, after receiving the SOAP message, it first retrieves whether there is an index of the second dynamic dictionary, and if so, the index of the second dynamic dictionary is solved. Analyze it into an index of the first dynamic dictionary and/or static dictionary, and then perform subsequent judgment and retrieval.

Even if the dictionary is constantly updated, there may be cases where the transmitted SOAP message cannot be replaced by an index. In this case, the operation may be performed directly according to the content indicated by the encoded information in the SOAP message.

Preferably, the step S50 further includes: the router retrieving whether the SOAP message is all the index of the first dynamic dictionary and/or the static dictionary stored in the router, if not, executing step S70; the step S70 reorganizing the index and the The content represented by the encoded information in the SOAP message is performed, and the operation is performed according to the recombined content; in step S90, the server determines whether the combination of the index and the encoded information, the individual encoded information constitutes at least one key value pair, and if so, the performing step S110; Step S110: The server updates each of the composed key-value pairs to a new index of the first dynamic dictionary stored in the server, and feeds the new index to the router; and in step S120, the router updates the feedback new index to the router. The first dynamic dictionary.

Preferably, after step S80, the method further includes: step S100: the server determines whether the encoded information constitutes at least one key value pair, and if yes, performs step S110; and the step S110 updates each of the composed key value pairs to the first stored in the server. A new index of a dynamic dictionary and each new index is fed back to the router; in step S120 the router updates each new index of feedback to the first dynamic dictionary stored in the router.

Specifically, if the SOAP message is composed of a mixture of index and coded information, the content of the index can be re-formed into a complete plain text SOAP message, and then the router performs the operation according to the complete message. . After performing the operation, the server will judge the SOAP message. When the SOAP message is composed of the index and the coded information, the server will determine whether the individual coded information can form a key-value pair, and the code. Whether the combination of information and index can form a key-value pair (as in the previous case, the key is in the dictionary, and the value is not). If a key-value pair can be formed, a new index will be generated for the key-value pair. Update to the first dynamic dictionary of the server and router for subsequent use; when the SOAP message is composed only of the encoded information, the server only needs to determine whether the encoded information can form a key-value pair, if possible, Generate corresponding new indexes for these key-value pairs, Update to the first dynamic dictionary of servers and routers. The next time you send these messages, you can use these indexes instead to better compress the size of the SOAP message.

Preferably, after step S60, the method further includes: step S61: the server determines whether the envelope element, the header element, and the body element are respectively composed of multiple indexes, and if yes, executing step S62; and step S62, respectively, updating the envelope element composed of multiple indexes. The header element and the body element are newly indexed into the second dynamic dictionary stored in the server, and the updated new indexes are fed back to the router; in step S63, the router updates the feedback new index to the second dynamic dictionary stored in the router.

Specifically, after multiple communications, most of the SOAP packets become part of the dictionary. In this case, the SOAP packets can be compressed twice. In this embodiment, when the envelope element, the header element, and the body element are all composed of indexes, a corresponding new index may be generated for each element, and an index set representing each element is stored in the second dynamic dictionary, next time. When the content is sent, the index in the second dynamic dictionary is directly sent, and when received, parsing is performed to obtain an index of the static dictionary and/or the first dynamic dictionary, and then combined to obtain a complete message content, and then according to the content The content performs the operation. The compression ratio is greatly improved, and the occupation of network bandwidth is reduced.

In other embodiments, as long as an element of each element has an index combination, a corresponding new index can be generated and stored in the second dynamic dictionary, and not all of the elements are completely combined by the index. And when an element is composed of an index set and coding information, the key value pair composed of the encoded information (or the encoded information is indexed) may be updated into the first dynamic dictionary, and the remaining index set is updated to the new index storage. To the second dynamic dictionary.

Preferably, before step S10, the method further includes: step S01: the server retrieves the SOAP message to be sent, whether there is content that can be replaced by the index stored in the dictionary of the server, and if so, step S02 is performed, and if not, step S03 is performed; The dictionary includes: a static dictionary, a first dynamic dictionary, and a second dynamic dictionary; in step S02, the server replaces the content represented by the index in the SOAP message with an index to form a new SOAP message; and the server sends a SOAP message to the router in step S03.

Specifically, before sending a SOAP message, it will be retrieved in its own dictionary. Whether the content can be replaced with a corresponding index to achieve the purpose of compressing the size of the SOAP message.

In another embodiment of the present invention, referring to FIG. 2, a SOAP message transmission method includes: Step S01: The server retrieves whether a SOAP message to be sent has content that can be replaced by an index stored in a dictionary of the server. If yes, go to step S02, if no, go to step S03; wherein, the dictionary includes: a static dictionary, a first dynamic dictionary and a second dynamic dictionary; in step S02, the server replaces the content represented by the index in the SOAP message with an index to form a new The SOAP message is sent to the router in step S03; the router receives the SOAP message sent by the server in step S10, the SOAP message includes an envelope element, a header element, and a body element, and the envelope element, the header element, and the body element each include at least a key value pair; the step S20 router parses the SOAP message; the step S30: the router retrieves the SOAP message whether there is an index of the second dynamic dictionary stored in the router, and if yes, executes step S31; if not, proceeds to step S40; The S31 router parses the index of the second dynamic dictionary existing in the SOAP packet, and obtains the second dynamic dictionary. The content represented by the index; wherein the content of the index represented by the second dynamic dictionary includes an index of the static dictionary, and/or an index of the first dynamic dictionary; and step S40: the router retrieves whether the SOAP message has the first dynamic stored in the router The index of the dictionary and/or the static dictionary, if yes, step S50 is performed, and if not, step S80 is performed; step S50, the router retrieves whether the SOAP message is all index of the first dynamic dictionary and/or static dictionary stored in the router. If yes, go to step S60, if no, go to step S70; step S60, the router reorganizes the content indicated by the index, and performs an operation according to the reorganized content; step S61, the server determines whether the envelope element, the header element and the main element are respectively Each of the indexes is composed of a plurality of indexes, and if yes, step S62 is performed; in step S62, the server updates the envelope element, the header element, and the body element composed of the plurality of indexes into a new index to be stored in the second dynamic dictionary of the server, and updates the update. Each new index is fed back to the router; in step S63 the router updates the new index of the feedback to the store The second dynamic dictionary step S70 of the router reassembles the index and the content represented by the encoded information in the SOAP message, and performs an operation according to the recombined content; in step S90, the server determines the combination of the index and the encoded information, respectively. Whether the encoded information constitutes at least one key value pair, and if so, executing step S110; step S80: the router performs an operation according to the content indicated by the encoded information in the SOAP message; and the step S100 determines by the server Whether the encoded information constitutes at least one key-value pair, and if yes, executing step S110; the step S110, the server updates each of the composed key-value pairs to a new index of the first dynamic dictionary stored in the server, and feeds back the new index to Router; step S120: The router updates the new index of the feedback to the first dynamic dictionary stored in the router.

Specifically, the transmission of the SOAP packet is bidirectional. In this embodiment, only the manner in which the server sends the SOAP packet to the router is performed, and the manner in which the router sends the SOAP packet to the server is the same. The router retrieves the index in the dictionary to replace the content of the SOAP message. If it is, it will be replaced and sent to the server. The server will retrieve its own dictionary based on the parsed message and parse the content of the SOAP message. The message content performs the operation. When updating the dynamic dictionary, it is judged by the server. If it needs to be updated, the server will feed back the content that needs to be updated to the router, let the router update, and the server will also store the content that needs to be updated into its own dictionary.

It should be noted that when the communication is more frequent and longer, the dynamic dictionary will become larger and larger, and the compression effect will be better and better, but the content of the dictionary will occupy a part of the memory of the server and the router, essentially It is to exchange memory space for network space.
