Technical Field

The invention relates to a scene multiplexing method and a scene multiplexing device in a multi-user shooting range environment, and belongs to the technical field of networks.

Background

In a network target range, a scene topology is defined as a graph set of points and edges formed by a series of network devices such as virtual machines and routers, each point in the set represents one network device, and the edges represent the connection relationship between the devices. All node devices in the topology can be instantiated through virtualization technologies such as OpenStack, and the instantiated topology is defined as a scene. Depending on the scene, the user can complete various network experiments and scientific verification in the shooting range.

The typical scene topology mainly comprises a network, a router, a target machine, various operating machines and other equipment. In the actual use process of the user, the user needs to wait for the completion of the topology instantiation before the subsequent operation can be performed. The instantiation needs to apply for physical computing resources one by one from a virtualization platform such as OpenStack according to various configurations of devices in the network (for an operating machine, for example, a win10 version operating machine of 4-core 16G), and each physical resource executes serial instantiation; a scenario is in an available state only after all corresponding physical resources have been instantiated. Physical resource instantiation is a time-consuming operation, users often need to wait for minutes, and the user experience is not friendly. Under the condition of overlarge user amount, each user competitively starts a scene and applies for physical resources in parallel; the lack of a control mechanism causes the bottom-layer physical resources to be exhausted, so that the response of the whole system is slowed down, and the overall throughput of the system is reduced.

Detailed Description

The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, a scene multiplexing method in a multi-user shooting range environment disclosed in the embodiment of the present invention, wherein an application process of a scene mainly includes the following steps:

(1) after a service system is started, initializing partial idle scenes according to the minimum number of idle scenes predefined by the system, and monitoring a request of a user for applying for scene use;

(2) after receiving the application of a user, judging whether an idle scene exists at present; jumping to the step (3) if an idle scene exists, otherwise, jumping to the step (5);

(3) randomly distributing users to a certain idle scene, and marking the current scene state as in use; if the scene is defined as a shared scene, at least one operating machine is allocated to the current user, and the rest virtual machines in the scene are added into an idle operating machine list;

(4) according to the maximum number of idle scenes preset by the system, judging whether the number of the current idle scenes is lower than a preset value, and asynchronously starting a new scene, wherein the starting process comprises the following steps:

asynchronously starting a new thread, trying to initialize an idle scene in the new thread, and ensuring that the number of the idle scenes is maintained at a certain stable level; before the thread carries out actual scene initialization, a distributed lock for initializing a new scene is obtained from a distributed consistency server, the lock ensures the uniqueness of scene initialization, and the problem of resource deadlock caused by simultaneous initialization of a plurality of scenes can be avoided; if the lock can be successfully acquired, actual idle scene initialization work is carried out; otherwise, the thread enters a distributed lock waiting state, monitors the use condition of the lock, and continues to try to acquire the lock and perform subsequent initialization work after other threads release the lock; the initialization process is as follows:

when initializing the idle scene, firstly judging whether the current physical resource can support the application of more scenes, if so, starting a new idle scene, otherwise, abandoning the application. The physical resources comprise key indexes such as memory, CPU number, disk size, network and the like, and as long as the surplus of a certain index of the physical resources does not meet the current application requirement, the physical resources are judged not to support the application of more scenes;

(5) inquiring a multiplexing strategy of a scene, if the current scene is a sharing scene, and supporting multiple users to multiplex the same scene (multiple students are allowed to use the same set of environment to complete network experiments together in use environments such as school teaching and the like), multiplexing the scene by using the following strategies:

traversing a running scene list, acquiring a scene with the number of multiplexing people not reaching the maximum number, distributing users to the scene in use, and marking the number of multiplexing people of the scene plus one; and if all scenes reach the maximum multiplexing number of people, adding the users into a scene waiting queue, if the queue is not full, prompting the current waiting number of people of the users, and if the queue is full, prompting the current unavailable scenes of the users.

And if the scene does not support multiplexing, trying to add the user into a scene waiting queue, if the queue is not full, prompting the current waiting number of people of the user, and if the queue is full, prompting the user that no available scene exists currently.

The scenario is composed of a plurality of virtual machines and necessary network intermediary devices (such as routers), and the scenario supporting multiplexing (shared scenario) has the following characteristics:

A) the scene is composed of at least two virtual machines;

B) a single user only operates part of virtual machines in the scene, the machines are called as operation machines, and the rest machines exist as target drone machines. The user needs to start from the current operation machine and obtain the designated content of the drone as the necessary basis for completing the training according to the necessary guide. The drone is used as a carrier of appointed contents, and has no actual calculation task, so that in the task of the type, the drone of one user can be reused as an operating machine of another user.

C) The multiplexing scheme is as follows: assuming that the total number of virtual machines in a scene is M (M > = 2), and the number of required operating machines for each user is N (N > = 1); after the scene is actually started, adding virtual machines which do not exist as operation machines in the scene into an idle operation machine list; when a user applies for scene multiplexing, judging whether the length of a list of current idle operating machines is larger than N, if the length of the list is larger than N, popping or randomly selecting N idle operating machines from the head of the list to serve as operating machines distributed to the current user; otherwise, the current scene is considered to reach the maximum multiplexing number of people, and the reuse is not supported.

As shown in fig. 2, the release flow of the scenario mainly includes the following steps:

(6) the user actively releases the scene after the scene is used, or the system actively releases the scene after a certain scene reaches the maximum use time; when the scene is released, judging whether a user waits for using the scene in the current scene waiting queue, if so, performing a jump step (7), otherwise, performing a jump step (8);

(7) clearing the scene operation record of the current user, informing a scene waiting queue, scheduling a first user in the waiting queue to a scene needing to be released by the current user, and ending a scene releasing process;

(8) judging whether the scene is a sharing scene, and jumping the sharing scene (9), otherwise jumping (10);

(9) if the number of the shared users in the current scene is reduced by one by the last user in the non-scene of the user, adding the operation machines distributed by the current user into an idle operation machine list after executing a cleaning action, and ending the scene release process; otherwise, go to step (10)

(10) And judging whether the physical resources of the current scene need to be released or not. The judgment standard is as follows: and if the number of the idle scenes in the system is larger than the preset idle scene value, indicating that the physical resources of the current scene need to be released. If the physical resource needs to be released, a step (11) of jumping is carried out, otherwise, a step (12) of jumping is carried out

(11) The system releases the physical resources occupied by the scene, such as CPU, disk, network, memory and the like, and finishes the scene release process after the release is finished;

(12) cleaning the use trace in the scene, recovering the scene to the initialization state, and marking the scene to be in the idle state for the next user to use.

Based on the same inventive concept, the scene multiplexing device in the multi-user shooting range environment provided by the embodiment of the invention comprises: the scene initialization unit is used for initializing the idle scene according to the predefined minimum number of the idle scenes and monitoring the request of the user for applying the scene; when the number of the current idle scenes is lower than the predefined maximum number of the idle scenes, asynchronously starting a new thread to execute the work of initializing the idle scenes; the scene application distribution unit is used for judging whether idle scenes exist or not after receiving a scene use request of a user; if yes, randomly allocating the user to an idle scene, marking the state of the allocated scene as in use, if the scene is defined as a sharing scene, allocating at least one operating machine to the current user, and adding the rest virtual machines in the scene into an idle operating machine list; if no idle scene exists, acquiring and judging whether the scene is a shared scene, and if the same scene is multiplexed by multiple users, multiplexing the scene by using the following strategies: traversing a running scene list, acquiring a scene with the number of multiplexing people not reaching the maximum number, distributing users to the scene in use, and marking the number of multiplexing people of the scene plus one; if all scenes reach the maximum multiplexing number of people, adding the users into a scene waiting queue, if the queue is not full, prompting the current waiting number of people of the users, and if the queue is full, prompting the current unavailable scenes of the users; and if the scene does not support multiplexing, trying to add the user into a scene waiting queue, if the queue is not full, prompting the current waiting number of people of the user, and if the queue is full, prompting the user that no available scene exists currently.

The device further comprises a scene release processing unit, which is used for judging whether a user waits for using a scene in the current scene waiting queue when the user actively releases the scene or the system regularly releases the scene, if so, clearing the scene operation record of the current user and informing the scene waiting queue, scheduling the first user in the waiting queue to the scene needing to be released by the current user, and ending the scene release process; otherwise, judging whether the scene is a sharing scene, if the scene is the sharing scene and the user is not the last user in the scene, subtracting one from the number of sharing users in the current scene, adding the operating machines distributed by the current user into an idle operating machine list after executing the cleaning action, and ending the scene release process; if the scene is a shared scene and the user is the last user in the scene or not, judging whether the physical resources of the current scene need to be released or not, if so, releasing the physical resources occupied by the scene by the system, and ending the scene release process after the release is finished; and if the release is not needed, cleaning the use trace in the scene, recovering the scene to an initialization state, and marking the scene to be in an idle state.
