Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a schematic flow diagram of a message generation method according to an embodiment of the present disclosure, where in the embodiment of the present disclosure, the message generation method includes:
s1, carrying out scheduling conversion processing on the initial message by using a preset load balancer to obtain an output message;
in the embodiment of the invention, the initial message is a network message which needs to be forwarded by the client, such as a TCP/UDP message.
In one application scenario of the embodiment of the present invention, the initial packet needs to be forwarded to a server node in a preset server cluster, but workloads of different server nodes of the server cluster are different. In order to ensure high availability of packet forwarding, the initial packet needs to be forwarded to a server node with a smaller load, so that a preset load balancer needs to be used to perform scheduling conversion processing on the initial packet, and a suitable server node is selected to obtain the output packet. The load balancer is a device which distributes all network requests to all server nodes of the server cluster in a balanced manner through various flexible distribution calculations.
In an embodiment of the present invention, referring to fig. 2, the performing scheduling conversion processing on the initial packet by using a preset load balancer to obtain an output packet includes:
s11, scheduling and screening all server nodes in the server cluster by using a scheduling algorithm in the load balancer to obtain a target server;
optionally, in this embodiment of the present invention, the scheduling algorithm includes: round robin algorithm, weighted round robin algorithm, least number of connections algorithm, weighted response algorithm.
S12, obtaining the information of the target server, and performing route conversion on the initial message according to the information of the target server to obtain the output message.
The information of the target server may include an IP and a port of the target server.
The initial message includes source IP/port and destination IP/port fields. In the embodiment of the present invention, the value corresponding to the source IP/port is an IP and a port of a client that sends an initial packet, and the value corresponding to the destination IP/port is an IP and a port corresponding to the load balancer, where the load balancer performs route conversion on the initial packet according to information of the target server to obtain the output packet.
In one embodiment of the present invention, the performing, according to the information of the target server, routing conversion on the initial packet to obtain the output packet includes: and setting a source IP/port field contained in the initial message as the IP and the port of the load balancer, and setting a destination IP/port field contained in the initial message as the IP and the port in the information of the target server to obtain the output message.
Because the IP and the port of the client cannot be seen in the output message, in another embodiment of the present invention, a preset field is added to the output message to store the information of the client, so as to ensure that the information of the client is not lost. The preset field may be, for example, toa field information. Wherein, the toa field includes the IP and the port of the client.
S2, inquiring the message format conversion rule corresponding to the load balancer in a preset conversion rule table;
when the load balancer is used for carrying out routing conversion on the initial message to obtain an output message, conversion rules corresponding to different load balancers are different, so that the embodiment of the invention inquires the message format conversion rule corresponding to the load balancer through a preset conversion rule table.
Optionally, in the embodiment of the present invention, an identifier code corresponding to the load balancer may be obtained, and a query statement is constructed by using the identifier code as a query parameter to query the conversion rule table for the message format conversion rule corresponding to the load balancer. The identification code corresponding to the load balancer may be an IP of the load balancer. Further, the message format conversion rule includes fields changed in the initial message and the output message, corresponding relations between the fields, newly added fields, and the like. Such as: the values corresponding to the source IP/port and the destination IP/port field in the initial message are respectively client IP, client port, VIP and V port, after passing through the load balancer A, the values corresponding to the source IP/port and the destination IP/port field in the initial message are changed into the values corresponding to the source IP/port and the destination IP/port field in the output message, namely local IP, local, RS IP and RS port, and the toa field and the value corresponding to the toa field are newly added in the output message, so that the message format conversion rule is that the value corresponding to the source IP field in the initial message corresponds to the local IP corresponding to the source IP field in the output message, the value corresponding to the source port field in the initial message corresponds to the local IP corresponding to the source port field in the initial message, the value corresponding to the source port field in the output message corresponds to the local IP corresponding to the destination IP field in the initial message, the value corresponding to the VIP field in the destination IP field in the initial message and the value corresponding to RS IP field in the output message, The value V port corresponding to the destination port field in the initial message corresponds to the value RS port corresponding to the destination port field in the output message, and the toa field is a newly added field in the output message.
S3, performing message difference analysis on the output message and the initial message according to the message format conversion rule to obtain a target difference value;
the embodiment of the invention determines the changed fields in the output message so as not to recalculate the checksum of the output message, thereby reducing the calculation time of the checksum and improving the generation efficiency of the message.
Optionally, referring to fig. 3, in an embodiment of the present invention, the S3 includes:
s30, extracting the value of the field in the output message according to the message format conversion rule to obtain a target field value set;
s31, extracting the value of the field in the initial message according to the message format conversion rule to obtain an initial field value set;
s32, converting each value in the target field value set and the value of the corresponding field in the initial field value set into a preset type of numerical value, and calculating to obtain an initial difference value;
because the types of the values corresponding to different fields are different, in order to facilitate unified calculation, in the embodiment of the present invention, the values corresponding to different fields need to be converted into the same type, and a preset type of numerical value is obtained and then calculated to obtain the corresponding initial difference. In one embodiment of the present invention, the preset type of value is a 16-bit binary value.
Optionally, in the embodiment of the present invention, the preset type of numerical value conversion is performed by using an ASCII code encoding manner.
In detail, in the embodiment of the present invention, each value in the target field value set and a value in a corresponding field in the initial field value set are converted into a preset type of numerical value, and then a difference is made to obtain the corresponding initial difference value.
And S33, calculating to obtain a target difference value according to all the initial difference values.
Specifically, in the embodiment of the present invention, the target difference is obtained by summing all the initial differences.
Further, since the output packet may have a newly added field, such as the toa field, relative to the initial packet, in order to ensure that all changed parts in the output packet are obtained, the embodiment of the present invention may further include:
s34, screening and judging newly added fields by using the target difference value and the message format conversion rule, converting the value corresponding to the newly added fields in the output message into a preset type of numerical value when the newly added fields exist, and then summing the numerical value and the target difference value to obtain an updated target difference value.
For example: the values corresponding to the source IP/port and the destination IP/port field in the initial message are respectively client IP, client port, VIP and V port, after passing through the load balancer A, the values corresponding to the source IP/port and the destination IP/port field in the initial message are changed into values corresponding to the source IP/port and the destination IP/port field in the output message, namely local IP, local, RS IP and RS port, and the toa option and the corresponding value are newly added in the output message The value V port corresponding to the destination port field in the initial message corresponds to the value RS port corresponding to the destination port field in the output message, and the toa field is a newly added field in the output message. Therefore, in the embodiment of the present invention, a value corresponding to the local IP field is subtracted from a value corresponding to the client IP field to obtain a difference a, a value corresponding to the local port field is subtracted from a value corresponding to the client port field to obtain a difference b, a value corresponding to the RS IP field is subtracted from a value corresponding to the VIP field to obtain a difference c, a value corresponding to the RS port field is subtracted from a value corresponding to the V port field to obtain a difference d, and a value corresponding to the toa field of the newly added field is e, so that the target difference is (a + b + c + d + e).
S4, extracting the inspection sum in the initial message, and carrying out message inspection sum calculation according to the target difference and the inspection sum to obtain an output message inspection sum;
in order to save computing resources and avoid overall computation of the checksum of the output message, the embodiment of the invention extracts the value corresponding to the checksum field in the initial message to obtain the checksum, and performs computation by using a preset algorithm according to the target difference and the checksum to obtain the checksum of the output message.
In detail, in the embodiment of the present invention, the calculating to obtain the checksum of the output packet according to the target difference and the checksum includes:
carrying out negation treatment on the inspection sum to obtain a first inspection sum;
calculating according to the first check sum and the target difference value to obtain a second check sum;
when the second check sum is zero, taking the second check sum as the check sum of the output message;
when the second checksum is not zero, adding the high N bit and the low N bit of the second checksum to obtain an updated second checksum;
and performing negation processing on the updated second checksum to obtain the checksum of the output message.
Further, in the embodiment of the present invention, the calculating according to the first checksum and the target difference to obtain a second checksum includes:
step A, judging whether the absolute value of the target difference value is larger than the first check sum;
step B, if the absolute value of the target difference is larger than the first check sum, judging whether the target difference is a negative value;
step C, if the target difference value is a negative value, performing borrowing processing on the target difference value, and adding the borrowed target difference value and the first check sum to obtain a second check sum;
for example: and if the target difference value is a, the target difference value after borrowing processing is (n +1) × 65535+ a, where n is the preset borrowing number.
Step D, if the target difference value is a non-negative value, adding the first check sum and the target difference value to obtain a second check sum;
and E, if the absolute value of the target difference is not larger than the first check sum, adding the first check sum and the target difference to obtain a second check sum.
Specifically, in the embodiment of the present invention, performing negation on the updated second checksum to obtain the checksum of the output packet, including:
step 1, judging whether the second check sum is zero or not;
step 2, if the second check sum is zero, taking the second check sum as an output message check sum;
step 3, if the second checksum is not zero, adding the high N bit and the low N bit of the second checksum to obtain a new second checksum,
optionally, in an embodiment of the present invention, N is 16.
Step 4, judging whether the second check sum is smaller than a preset threshold value or not;
optionally, in this embodiment of the present invention, the preset threshold is 0 xffff.
Step 5, if the second check sum is smaller than a preset threshold value, negating the second check sum to obtain an output message check sum;
in detail, the embodiment of the present invention inverts the second checksum to perform a bitwise inversion operation on the second checksum, such as: the second checksum is 00000101, and the second checksum is negated to yield an output message checksum of 11111010.
Step 6, if the second check sum is greater than or equal to a preset threshold value, judging whether the second check sum is zero;
step 7, if the second check sum is zero, taking the second check sum as an output message check sum;
and 8, if the second checksum is not zero, adding the high N bit and the low N bit of the second checksum to obtain a new second checksum, and returning to the step 1.
Optionally, in an embodiment of the present invention, N is 16.
For example: the second checksum is 0x11223344, where 0x1122 is the high 16 bits and 0x3344 is the low 16 bits, and 0x1122 and 0x3344 are added to obtain a new second checksum.
S5, carrying out message construction according to the output message inspection sum and the output message to obtain a target message.
In the embodiment of the present invention, the checksum field is a common field in all network messages, and the checksum field in the output message is checked and replaced with a value corresponding to the checksum field in the output message, so as to obtain the target message.
