according to k2Rank of order, priority response and execution k2Higher value user network low latency requirements;
according to k3Rank of order, priority response and execution of k3High-value user network large flow demand;
further, the allocation method includes using a dynamic allocation system for satellite bandwidth management, as shown in fig. 1, the allocation system includes:
the user management module is configured to manage the distribution point account of the user, and comprises the steps of increasing operation, checking and canceling the value of the distribution point, and informing the user to operate and supplement the distribution point when the allowance of the distribution point account is insufficient; simultaneously recording the setting value of the verification and cancellation proportion parameter of the user;
the network monitoring module is used for monitoring various working conditions of the satellite network, acquiring the verification and cancellation proportion parameter of the user and dynamically responding to the network use requirement of the user according to the verification and cancellation proportion parameter; the network monitoring module further comprises:
(1) a load submodule for counting the total load degree of the satellite network and feeding back the network load index bt；
(2) A delay submodule for feeding back a delay index u of the satellite network transmissiont；
(3) Flow submodule for feeding back a flow function wuser(t) an output value;
(4) the dynamic control submodule is used for distributing the bandwidth of the user according to the core-cancellation proportion parameters of the users and controlling the delay performance;
in the actual working process of the satellite network, factors influencing the application quality of the satellite network are many, the main concerned parameters are mainly bandwidth and delay, and the overall speed performance of the satellite network is actually the result of the bandwidth and the delay;
as shown in the diagram of fig. 2, the bandwidth refers to the amount of data that can be transmitted in a unit time (generally, 1 second), and can be understood as the caliber of the data pipe;
as shown in FIG. 3, latency refers to the time required for a data request to reach the data server and then the data to return to the target requestor;
"network bandwidth" and "network latency" are sometimes used interchangeably, but they actually describe two separate concepts;
given the scenario applied to Web page access requests, the following statements more readily explain the differences between them:
(1) if the bandwidth of the network is good, but the delay is poor: web pages take a long time to start loading, but once the initial connection is completed, the rest of the page is loaded immediately;
(2) if the delay of the network is good and the bandwidth is poor: the Web page can start to load almost immediately, but the page loading is slow, and the data which can be loaded in each unit time is little;
on the other hand, for calculating the network use cost of the user, the degree of the user using the network can be basically and completely expressed by setting the bandwidth and the delay of the user and then calculating the consumed network flow, so that the cost to be deducted is set;
therefore, based on the fact that the resources of the satellite network are relatively precious, and users have different application scenes and network use requirements, a dynamic bandwidth allocation mode considering the bandwidth, delay and flow of the satellite network is provided, so that the use requirements and cost of the users are balanced, and the performance utilization rate of the satellite network is improved;
in a user situation mainly oriented to the application for instant voice communication, the verification and cancellation proportion parameter k is very high for the user because the application for voice communication requires very high instantaneity and the bandwidth requirement of voice data is very low1The value of (d) may be set to a lower level; nuclear-to-sales ratio parameter k2The value of (a) is set to an upper-middle level for ensuring that the delay is in a fast response state; nuclear-to-sales ratio parameter k3The value of (c) can also be set to a lower level since the overall flow consumption does not vary significantly;
in another user situation facing to periodic ground data transmission, the data transmitted by the user is transmitted periodically every day, so that the requirement on the overall speed of the network is not high, and relatively, the amount of the transmitted data is large, and the consumed flow is large, so that the cancel-and-verify proportion parameter k is large1And k2Can be set to a lower level value, and k3Is set to a higher level for ensuring that its request for traffic transmission can continue to be responded to and executed by the satellite network;
in another user situation facing news reports, the user needs to instantly transmit the report scene pictures to the news center, so that the requirement on the bandwidth of a short time is high, and a plurality of high-definition pictures with large capacity can be transmitted in a short time; on the other hand, the user has certain requirements on network delay, and the requirements are used for ensuring that the transmission time is within a controllable range; meanwhile, the degree of network flow consumption is unstable; therefore, preferably, the setting of the verification and cancellation ratio parameter can be as follows: k is a radical of1Set to a higher level, k2Intermediate level, k3Moderate levels;
optionally, the service provider of the satellite network sets the reference point rate std according to the overall satellite network operation cost and in consideration of the possibly participating market competition environmental factors; the reference point rate std is used as an important calculation factor of the verification and cancellation function p, and obviously influences the distribution point consumption speed of users, so that a satellite network service provider can reasonably set the reference point rate std according to various factors;
further, the network load index btFor representing the overall load level of the current satellite network, namely:
in formula 4, V is the overall bandwidth load of the current satellite network, VmaxA is a buffer factor for the maximum bandwidth load of the satellite network, and is used for reserving reasonable calculation margin when the bandwidth is dynamically changed;
by the network load index btThe consumption rate of the distribution point consumption of the user is increased when the network bandwidth load is higher, and meanwhile, the parameter k is passed1The adjustment of (3) makes the amplitude of the distribution point consumption rise of the user with low bandwidth requirement relatively smaller;
further, the delay index utThe system is used for indicating whether the delay of the current satellite network meets the standard network delay promised by the distribution system after negotiation with the user; root of herbaceous plantAccording to equation 2, the actual network delay l is greater than the standard network delay lproThen the delay index u is accordinglytBecomes smaller, so that the consumption of allocation points is partially reduced for the user; and parameter k1Similarly, while passing the parameter k2Is adjusted so that the parameter k2Setting a higher user to obtain a better network delay demand response; on the other hand, when the network delay performance is reduced, the parameter k2The higher user is set to have a greater degree of exemption from the allocation points; and when the network delay is normal, the parameter k2The allocation point consumption for the higher users is also relatively fast.
The second embodiment:
this embodiment should be understood to include at least all of the features of any of the foregoing embodiments and further modifications thereon;
for a user with strong application scene regularity, the relation function of network flow-time is changed periodically; FIG. 3 shows a statistical plot of flow versus time for a user over a period of one week; counting a flow-time function of a user through big data, and establishing a flow model q (t) which can be used for estimating the flow consumption speed of the user at a certain t moment;
further, by integrating the flow patterns Q (t) over time, Q can be calculateduser(t), namely:
according to the calculation method of equation 3, when the actual consumption flow of the user is greater than the theoretical consumption value, the flow function W is determineduser(t) increases accordingly, speeding up the consumption of the user's allocation points; on the contrary, when the actual consumption flow of the user is smaller than the theoretical consumption value, the consumption of the distribution points of the user can be slowed down, and a certain cost reduction effect is brought to the user.
Example three:
this embodiment should be understood to include at least all of the features of any of the foregoing embodiments and further modifications thereon;
furthermore, in order to give greater flexibility to users of the satellite network, the user is allowed to adjust the verification and cancellation proportion parameter k according to actual application conditions1、k2、k3One or more than one of the numerical values;
in one implementation, the user is allowed to perform self-adjustment on the verification and cancellation proportion parameter within a certain numerical range; for example, under some temporary demands, the user needs to temporarily increase the upper limit value of the bandwidth and raise the priority level of the bandwidth response of the distribution system; in this case, the user adjusts the parameter k1To a higher value, thereby achieving a high bandwidth requirement for the interim period; and can reset the parameter k after the temporary requirements are over1Reducing to the original level; setting the numerical range of the verification and cancellation proportion parameter can protect the service income of a satellite network service provider and avoid the phenomenon that a user excessively adjusts the numerical value of the verification and cancellation proportion parameter to generate a poor calculation value of the verification and cancellation function p;
in one implementation, the distribution system generates the sets of the verification and cancellation ratio parameters k by evaluating the overall bandwidth and delay condition of the current satellite network1、k2、k3The optimized numerical combination is recommended to users with specific network requirements, so that the core-cancellation function p obtains a lower consumption value based on different user requirements; set of parameters k, e.g. "adapted for instant voice communication1、k2、k3Combined, or as a set of parameters k "adapted for geographical data transmission1、k2、k3Combining; in this way, the self-adjustment parameter k of the user is reduced1、k2、k3Resulting in wasted time and testing costs.
