An embodiment of the present invention provides an intelligent network switch based on sip, and as shown in fig. 1, the structural schematic diagram of the intelligent network switch includes:
the configuration module is used for receiving configuration information and carrying out initialization configuration in the intelligent network switch, wherein the initialization configuration comprises the step of configuring a plurality of communication channels with different bandwidths for each terminal connected with the intelligent network switch. The terminal can be a computer, a mobile phone, a tablet and other terminals. In the initialization configuration, a plurality of communication channels with different bandwidths are actively configured for the connected terminals to meet different data transmission requirements.
And the corresponding module is used for correspondingly setting a plurality of communication channels with different bandwidths with different types of multimedia sessions, wherein each type of multimedia session corresponds to at least one communication channel. The multimedia session may be a voice-type multimedia session, a video-type multimedia session, etc., among others. The multimedia session in the present invention is not limited to the voice type multimedia session and the video type multimedia session, but is exemplified by the voice type multimedia session and the video type multimedia session. During actual data transmission, the data of voice may be smaller than the data of video. Therefore, the invention corresponds to at least one communication channel for each multimedia session, and the communication channel is specially used for transmitting data of a certain multimedia type session so as to ensure the stability of data transmission when the multimedia session is carried out.
And the selection module is used for determining the type of the corresponding multimedia session and the corresponding communication channel according to the received session request, and establishing a multimedia data transmission channel with other terminals based on the type of the multimedia session and the communication channel. Request information can exist in the session request, the request information comprises the attribute of the session request, for example, if the session request is an instant video request, the selection module classifies the session request as a multimedia session of a video type; for example, if the session request is an instant voice request, the selection module classifies it as a voice-type multimedia session. For example, if the session request is a video download request, the selection module may classify the session request as a general session, and the present invention does not allocate a corresponding data transmission channel to the general session, so the intelligent network switch may allocate a corresponding data transmission channel and a corresponding bandwidth according to the situation, and the technical solutions of allocating a bandwidth to the general session and establishing a data transmission channel may be completed by the prior art.
After the type of the multimedia session corresponding to the session request is determined, a multimedia data transmission channel is established with other terminals based on a communication channel corresponding to the type of the multimedia session.
The intelligent network switch and the converged communication system based on the sip can configure a plurality of communication channels for each terminal when the intelligent network switch is connected with the terminal for the first time, and each communication channel corresponds to different types of multimedia sessions so as to be used for transmitting different multimedia data. When receiving the session request, the corresponding communication channel is determined according to the type of the multimedia session corresponding to the session request, so that the communication channel based on the session request can meet the data transmission requirement and the data transmission stability required by an online conference and the like. After the communication channel is configured, the communication channel is a dedicated channel and is only used for data transmission of the multimedia session of the type corresponding to the communication channel, so that the situation that the terminal has data congestion in the data transmission process of the corresponding multimedia session type is ensured, the situation that the whole data transmission system has data congestion is avoided, and the stability of data transmission provided by the invention is ensured.
In one possible embodiment, as shown in fig. 2, the configuration module includes:
the intelligent network switch comprises a first obtaining unit and a second obtaining unit, wherein the first obtaining unit is used for obtaining the number of terminals connected with the intelligent network switch, and setting a first bandwidth occupation ratio and a second bandwidth occupation ratio of the intelligent network switch based on the number of the terminals.
Due to the network or the attribute of the intelligent network switch device, the bandwidth of the intelligent network switch has a certain range in a certain time period, so the total data transmission amount of all the terminals connected with the intelligent network switch should be within the range of the bandwidth, and if the bandwidth is exceeded, the system cannot stably work, so the number of the terminals cannot be infinitely increased. The number of terminals is in a range, say, within 100, within 300, etc.
The invention can determine the first bandwidth occupation ratio and the second bandwidth occupation ratio according to the number of the terminals, when the number of the terminals is in a certain range, the first bandwidth occupation ratio can be larger and larger, but when the number of the terminals is increased to a certain range, the first bandwidth occupation ratio can be kept unchanged, because the first bandwidth occupation ratio pre-allocates the bandwidth, the pre-allocated bandwidth is only used for transmitting the multimedia data of the corresponding multimedia session and is not occupied by other sessions, in order to ensure that other sessions can be normally performed, a critical value is set for the first bandwidth occupation ratio or a function is used for dynamically adjusting, so that the first bandwidth occupation ratio is prevented from being infinitely larger to prevent other common sessions from being incapable of normally transmitting the data.
And the bandwidth calculating unit is used for calculating according to the first bandwidth occupation ratio and the rated bandwidth of the current intelligent network switch to obtain total pre-allocated bandwidth, and calculating according to the second bandwidth occupation ratio and the rated bandwidth of the current intelligent network switch to obtain total randomly allocated bandwidth. The present invention calculates a first bandwidth occupancy ratio, which may be 30 percent, 40 percent, etc., based on the nominal bandwidth in calculating the first bandwidth occupancy ratio and the second bandwidth occupancy ratio. In the above scheme, the total pre-allocated bandwidth that the intelligent network switch can pre-allocate for all terminals connected to the intelligent network switch is calculated, and when the sub-pre-allocated bandwidth is allocated to each terminal, the allocation is performed according to the total pre-allocated bandwidth.
And the initialization unit is used for generating a plurality of sub pre-allocated bandwidths with the same bandwidth based on the total pre-allocated bandwidth and the quantity of other terminals so that the terminals establish a multimedia data transmission channel through the sub pre-allocated bandwidths. After the total pre-allocated bandwidth is obtained, the sub-pre-allocated bandwidth is determined according to the number of the terminals, and the terminals can transmit corresponding multimedia data according to the sub-pre-allocated bandwidth.
The invention can determine the first bandwidth occupation ratio and the second bandwidth occupation ratio of the whole intelligent network switch according to the number of the terminals connected with the intelligent network switch, obtain the total pre-allocated bandwidth through the first bandwidth occupation ratio to pre-allocate each terminal, respectively allocate sub-pre-allocated bandwidth to each terminal, the terminal can preferentially use the sub-pre-allocated bandwidth when initiating the multimedia session and needing to transmit the multimedia data, and the stable transmission of the multimedia data can be ensured through the sub-pre-allocated bandwidth.
The sub pre-allocated bandwidth provided by the invention can only transmit data of the multimedia session, and when the sub pre-allocated bandwidth cannot meet the data transmission of the multimedia session, the data of the multimedia session is transmitted by combining the total randomly allocated bandwidth, so that the stability of the multimedia data transmission is ensured.
In one possible embodiment, each sub-pre-allocated bandwidth is calculated by the following formula, including:
Figure BDA0003153585830000091
where x is the sub-pre-allocated bandwidth per terminal, EForehead (forehead)Is the rated bandwidth of the intelligent network switch, k is the number of terminals connected to the intelligent network switch, a is a constant,
Figure BDA0003153585830000092
is a first bandwidth occupancy ratio.
In the present invention, a may be set according to the attribute of the intelligent network switch, for example, if the intelligent network switch is small, which may be suitable for connecting with 100 terminals, then a may be 50; for example, if the intelligent network switch is medium, which may be suitable for connecting to 300 terminals, then a may be 150; for example, if the intelligent network switch is large and it may be appropriate to connect to 500 terminals, then a may be 250 at this time.
Moreover, the invention can also adjust the value of a according to the operation habits of different terminals, for example, a plurality of terminals connected with an intelligent network switch need to carry out large-scale conference communication frequently, and the value of a can be increased at the moment, so that the value of a can be increased
Figure BDA0003153585830000093
The value becomes large. For example, a number of terminals connected to an intelligent network switch rarely engage in conference communication, and the value of a may be reduced to reduce the number of a
Figure BDA0003153585830000094
Figure BDA0003153585830000095
The value becomes small.
The invention can allocate multimedia communication channels with different bandwidths for different types of multimedia sessions, and because different types of multimedia sessions need to occupy different bandwidths in an actual scene, the occupation rate of the bandwidth is saved on the premise that the transmission stability of each type of media session is ensured by allocating corresponding bandwidth. And reflecting the bandwidth amount required by each type of multimedia session according to the bandwidth occupation coefficient, and calculating the bandwidth occupation coefficient and the sub-pre-allocated bandwidth to obtain a final multimedia communication channel of each type of multimedia session so as to realize the purpose of optimally allocating the sub-pre-allocated bandwidth.
In one possible embodiment, the method further comprises:
and the dividing unit is used for acquiring the sub-pre-allocated bandwidth and preset different types of multimedia session information, wherein each type of multimedia session has a bandwidth occupation coefficient corresponding to the multimedia session. Wherein the bandwidth occupancy factor may be a number, but the sum of the bandwidth occupancy factors for all types of multimedia sessions is 100. The amount of data transmission for this type of multimedia session is reflected by the bandwidth occupancy factor. For example, the bandwidth occupation coefficient corresponding to the multimedia session requiring a larger amount of data to be transmitted is higher, and the bandwidth occupation coefficient corresponding to the multimedia session requiring a smaller amount of data to be transmitted is smaller.
And the distribution unit is used for respectively distributing multimedia communication channels with different bandwidths to each type of multimedia session based on different bandwidth occupation coefficients.
In one possible embodiment, multimedia communication channels of different bandwidths are allocated by the following formula, including:
Figure BDA0003153585830000101
wherein, T1Bandwidth of a multimedia communication channel for a first type of multimedia session, T2Bandwidth of a multimedia communication channel for a second type of multimedia session, TnBandwidth of a multimedia communication channel for a multimedia session of the nth type, p1Bandwidth occupation coefficient, p, for a first type of multimedia session2Bandwidth occupation factor, p, for a second type of multimedia sessionnBandwidth occupation factor for the nth type of multimedia session, x pre-allocating bandwidth for each terminal's sub-set, EForehead (forehead)Is the rated bandwidth of the intelligent network switch, k is the number of terminals connected to the intelligent network switch, a is a constant,
Figure BDA0003153585830000102
Figure BDA0003153585830000103
is a first bandwidth occupancy ratio.
Through the formula and the technical scheme, the bandwidth of the multimedia communication channels of different types of multimedia sessions can be obtained by calculating according to the bandwidth occupation coefficients of the different types of multimedia sessions, the intelligent distribution of the multimedia communication channels to each terminal is realized, and the transmission of data based on the distributed multimedia communication channels when the terminals carry out corresponding multimedia sessions is ensured.
In one possible embodiment, the configuration module comprises:
and the second acquisition unit is used for acquiring the actual data transmission total amount of all the terminals in each preset time period and the operation types of the terminals, wherein the operation types comprise a multimedia operation type and a non-multimedia operation type. Each preset time period may be one hour, two hours, etc. In an actual data transmission scene and an actual data transmission operation process, an operator in front of each terminal can perform different operations according to different requirements, wherein the operations comprise a multimedia operation type and a non-multimedia operation type. Wherein the multimedia operation type can be instant video, instant voice, etc., and the non-multimedia operation type can be downloading of a file, transmission of a file, etc.
And the calculating unit is used for calculating the proportion of the data of the multimedia operation type to the data of the non-multimedia operation type in each time period. Due to production and life laws, the meeting time of each company and department is periodic, such as nine o 'clock to ten o' clock, 17 o 'clock to 18 o' clock later, and the like. The ratio of data of the multimedia operation type to data of the non-multimedia operation type may be different and dynamically varied in each time period.
And the dynamic adjusting unit is used for dynamically adjusting the first bandwidth occupation ratio and the second bandwidth occupation ratio according to time periods based on the proportion of the data of the multimedia operation type and the data of the non-multimedia operation type. Therefore, when the first bandwidth occupation ratio and the second bandwidth occupation ratio are allocated, the ratio of the data of the multimedia operation type to the data of the non-multimedia operation type needs to be adjusted according to each time period. For example, if the ratio of the first bandwidth occupation ratio to the second bandwidth occupation ratio is 1 to 2 in the first time period and the ratio of the first bandwidth occupation ratio to the second bandwidth occupation ratio is 1 to 3 in the second time period, the first bandwidth occupation ratio in the first time period is greater than the first bandwidth occupation ratio in the second time period.
In a possible embodiment, the dynamic adjustment unit is further configured to perform the following steps, including:
acquiring the actual data transmission total amount of the current terminal in the same time period within the past preset days;
comparing the data of the multimedia operation type in the same time period within the previous preset number of days with the actual data transmission total amount to obtain a first bandwidth occupation ratio;
and comparing the data of the non-multimedia operation type in the same time period within the previous preset number of days with the actual data transmission total amount to obtain a second bandwidth occupation ratio.
Wherein, the adjusting range can be adjusted by the following steps:
Figure BDA0003153585830000111
wherein the content of the first and second substances,
Figure BDA0003153585830000112
is the amount of data of the multimedia operation type in the z-th time period within n days,
Figure BDA0003153585830000113
