Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, an embodiment of the present invention provides a data forwarding method, which may include the steps of:
101. and analyzing the received data packet based on a preset analysis rule to obtain a data field and a load of the data packet, wherein the data field at least comprises protocol header data of the data packet.
The data packet transmitted in the network can be divided into a message header and a load, wherein a data set extracted from the message header according to a certain rule is a data field, the data field can comprise a protocol header data part to acquire all data, and a user can extract the data according to the need. The extraction user of the data field can acquire the protocol header data required by the user based on the self-defined analysis function, and the invention is not repeated here.
102. And screening the data domain based on the matching condition to obtain target data conforming to the matching condition.
The user can screen the obtained data fields according to the required matching condition, so as to obtain the target data wanted by the user, wherein the data set in the data fields is { a, b, c, d }, but a=1 in some network messages, a=2 in some network messages and the like, and when the condition of the user wanted to screen is a=1, the user only needs to screen the data messages of a=1 in the data fields and then perform subsequent calculation without considering other screening conditions.
103. And calculating the target load associated with the target data based on a preset calculation rule to obtain a new load.
After target data wanted by a user are obtained, target load corresponding to the target data can be calculated according to calculation rules set by the user, and the user can carry out data processing such as logic operation, comparison operation and the like on the load data according to the length of the load to obtain the load data wanted by the user. The calculation is a user-defined function, and the user-defined function comprises an input data format, a calculation method and an output data format. For example, it is defined that the first 4 bytes and the subsequent 4 bytes in the payload are added to obtain a 4-byte calculation result, and the 8 bytes in the original payload are replaced by the calculation result. The condition is defined by user, the data of the data field is taken as input, and the operation rule is defined, if the output 1 indicates that the condition is met, and 0 indicates that the condition is not met.
104. The data field and the new payload are reassembled into a new data packet.
After the load calculation is completed to obtain a new load, splicing the obtained new load and the data field according to the position relation between the message head and the load to obtain a new data packet.
105. And obtaining a forwarding port from the protocol header data of the data domain based on a preset forwarding rule, and forwarding the new data packet to the forwarding port.
The forwarding operation commonly used in the sending of network packets takes some elements in the data domain as input, and performs port lookup in a lookup table (similar to a dictionary structure), and outputs the labels of the ports that need to perform data forwarding, such as 1 port, 2 ports, 3 ports, and the like.
The data forwarding method realizes flexible data packet analysis, user-defined forwarding, in-band aggregation calculation and the like. Compared with the traditional network equipment which can only support the existing standard protocol, the method can meet the personalized requirements of users and enhance the operability of data forwarding colors.
As a possible implementation manner of the foregoing embodiment, the specific process of parsing the received data packet based on the preset parsing rule to obtain the data field and the load of the data packet may include:
and analyzing the data packet layer by layer based on the jump condition among the network protocols of each layer of the data packet until the data field and the load of the data packet under the network protocol of the lowest layer are obtained.
The jump condition may include a jump flag bit between adjacent network protocols, and the analyzing the data packet layer by layer based on the jump condition between the network protocols of each layer of the data packet until the data field and the load of the data packet under the network protocol of the lowest layer are obtained includes:
and starting from the network protocol of the highest layer, identifying the skip zone bit in the network protocol, and skipping to the target network protocol to carry out the skip zone bit based on the target network protocol represented by the identified skip zone bit until the network protocol of the lowest layer is skipped to obtain the data field and the load of the data packet.
Specifically, the data packet sequentially completes the analysis processing of the data packet according to the jump condition of the protocol tree. According to the subordinate relations among network protocols in each layer in the network structure, the jump zone bit in the layer-by-layer extraction network protocol obtains the network protocol of the next layer to be jumped, which is characterized by the jump zone bit, according to the filling value of the jump zone bit, and further realizes the layer-by-layer jump. For example, the structure of a network is ethernet, virtual local area network, network transmission protocol (IPv 4), and finally Transmission Control Protocol (TCP) and user packet protocol (UDP) at the same level from top to bottom, then the data parsing process may be:
when the ethernet Eth is parsed, when the skip flag bit ethtype=0x9100, the next layer of message protocol is VLAN, and the next step is to skip to VLAN (virtual local area network) for execution.
When ethtype=0x0800, the next layer message protocol is IPv4, and the next step is to skip to IPv4 execution.
When the VLAN is analyzed, when the skip flag bit type=0x0800, the next layer of message protocol is IPv4, and the next step is to skip to IPv4 for execution.
When the IPv4 is resolved, when the skip flag protocol=6, the next layer of message protocol is TCP, and the next step is to skip to TCP for execution.
When the skip flag protocol=17, the next layer of message protocol is UDP, and the next step is to skip to UDP execution.
It will be appreciated that those skilled in the art may select other parsing modes to parse the network protocol as needed, and the present invention is not limited herein.
Referring to fig. 2, in some embodiments of the present invention, the data fields are filtered based on the matching condition to obtain the target data meeting the matching condition, which may include the following steps:
201. target data characterized by target locations in the matching conditions are extracted from the data field.
202. And comparing the target data with example data in the matching condition to obtain a matching identifier, wherein the matching identifier has at least two states, the first state represents that the first state is matched, and the second state represents that the second state is not matched.
203. And identifying the matching identification, and taking the data domain as target data if the matching identification is in the second state.
Specifically, the transmission direction of the data can be determined according to the network address in the data field, and data can be screened according to the transmission direction, for example, the condition of screening the data field is that the data field is sent to the user a, the transmission direction can be used as a screening condition, the transmission direction is respectively used as corresponding matching identifiers, the matching state is characterized, and the network data packet meeting the condition is subjected to subsequent calculation.
Further, referring to fig. 3, calculating the target load associated with the target data based on the preset calculation rule to obtain a new load may include:
301. and acquiring at least two groups of data to be calculated from the target load based on the data distribution relation specified by the user.
302. And inputting each group of data to be calculated into the associated calculation function, and calculating based on the calling relation among the functions to obtain a new load.
Specifically, the calculation of the target load may be performed based on symbolic programming, with the user specifying the input data, calculation steps and methods, and output data in advance. Symbol programming is suitable for processing of data streams and can be used as a custom for network packet processing. For example:
A＝Variable('A')
B＝Variable('B')
C＝B*A
D＝C+Constant(1)
#compiles the function
f＝compile(D)
d＝f(A＝np.ones(10),B＝np.ones(10)*2)。
the calculation process means that the obtained A and B are added to obtain C, the C and the 1 are added as an input function to obtain D, and then the D is subjected to the next calculation.
Reassembling the data field and the new payload into a new data packet may specifically include:
and splicing the data field and the new load in sequence based on the position and the arrangement relation between the data field and the original load. Because the positions between the data fields and the loads and the respective occupied digits in the same network protocol are determined, the new data is correspondingly filled and spliced to obtain a new data packet.
Further preferably, the obtaining a forwarding port from the protocol header data of the data domain based on a preset forwarding rule, and forwarding the new data packet to the forwarding port includes:
and searching a key value associated with the key word in a preset key value storage system by taking the network address acquired from the protocol header data as the key word.
And then forwarding the new data packet to a forwarding port corresponding to the key value.
The determination of the forwarding port can be performed according to a lookup table, the lookup table is stored in a key-value form, part of data in a data field can be used as a key, and the value can be obtained from the lookup table, and the value contains information of the forwarding port. The forwarding port may be a number, for example, 1-48 is a serial number of the front panel of the switch, and then a corresponding forwarding end can be found according to the corresponding relationship between the forwarding port and the serial number for forwarding.

comparing the target data with example data in the matching condition to obtain a matching identifier, wherein the matching identifier at least has two states, the first state representation is matched, and the second state representation is not matched;
identifying the matching identifier, and taking the data field as the target data if the matching identifier is in the second state;
the calculating the target load associated with the target data based on the preset calculating rule to obtain a new load includes:
acquiring at least two groups of data to be calculated from the target load based on a data distribution relation specified by a user;
inputting each group of data to be calculated into an associated calculation function, and calculating based on the calling relation among the functions to obtain the new load;
wherein said reorganizing said data field and said new payload into a new data packet comprises:
based on the position and the arrangement relation between the data field and the original load, splicing the data field and the new load in sequence;
the obtaining a forwarding port from the protocol header data of the data domain based on a preset forwarding rule, forwarding the new data packet to the forwarding port, includes:
using the network address obtained from the protocol header data as a keyword, and searching a key value associated with the keyword in a preset key value storage system;
and forwarding the new data packet to a forwarding port corresponding to the key value.
