Description
Technical Field
The invention relates to the field of network communication, in particular to a cross-domain switching resource dynamic allocation method.
Background
In the existing network, the requirement for cross-domain controlled transmission of a service system among different networks is higher and higher, wherein a gatekeeper, a unidirectional transmission device, a bidirectional transmission device, a firewall, a bastion machine and an interconnection control device account for a considerable proportion in the deployment of the cross-domain controlled transmission network, and as services are increasingly complicated, service guarantee and service control become more and more complex. At present, for controlled intercommunication of services across different network domains, a mode of analyzing service logic and adapting to corresponding cross-domain controlled network equipment is mainly adopted for support. With the gradual expansion of the types and the number of the cross-domain services, the increase of the types and the number of the correspondingly deployed cross-domain switching devices will cause the waste of cross-domain switching resources, and in the process of device management, operation and maintenance, managers can only start from the cross-domain services to judge whether the services are normal, but cannot manage the network devices providing the cross-domain services.
Most of the currently common service cross-domain switching devices are deployed at the edge of the network, and the devices themselves have respective service capabilities and service bearing states, such as: the utilization rate of a CPU (Central processing Unit), the utilization rate of a memory, the bandwidth of a current bearing service, the types of externally provided services of equipment, the access of a physical link of the equipment and the like, and the working capacity and the current working condition of the equipment are objectively described by the state indexes. Due to the non-centralized unified management of the working state of the cross-domain switching equipment, the cross-domain services are repeatedly deployed to the same type of cross-domain switching equipment in the deployment process. A great deal of manpower waste, a great deal of material resources waste and a great deal of bandwidth waste in network bearing planning are caused in the maintenance process and the implementation process.
Disclosure of Invention
Aiming at the problems that the working state of cross-domain switching equipment is non-centralized and unified managed in the prior art, so that a large amount of manpower and material resources are wasted in the implementation and maintenance process of deploying cross-domain services and a large amount of bandwidth is wasted in network bearing planning, the invention provides a cross-domain switching resource dynamic allocation method.
In order to achieve the purpose of the invention, the invention adopts the technical scheme that:
a method for dynamically allocating cross-domain switching resources is provided, which comprises the following steps:
step one, the management control system uniformly classifies the cross-domain switching equipment: the method comprises real-time | bidirectional, real-time | unidirectional, non-real-time | bidirectional, non-real-time | unidirectional and the like, and classifies cross-domain switching equipment (such as a network gate, internetwork interconnection control equipment, unidirectional transmission equipment and the like) according to the types of bearable services (real-time and non-real-time) and the transmission characteristics (bidirectional and unidirectional) of the equipment, so as to provide an equipment election dictionary for switching resource allocation.
And secondly, the management control system communicates with the cross-domain switching equipment, collects the running state (CPU utilization rate and memory utilization rate) and the service load state (service current load bandwidth) of the cross-domain switching equipment, and performs unified online state presentation, wherein the specific process comprises the following steps:
2.1 inputting the IP address of the deployed cross-domain switching equipment into a management and management control system;
2.2 the management control system adopts an active inquiry mode to acquire the self state of the input cross-domain switching equipment, and the method comprises the following steps: information such as device type, device self-running state, device physical link access state, device service providing type (such as FTP, mail, database migration and the like), device processing capacity (tera performance, gigabit performance and the like) and the like;
2.3 the management control system associates the accessed cross-domain switching equipment with the classification dictionary after acquiring the self state information of the cross-domain switching equipment;
2.4 the management control system acquires the current service bearing state of each cross-domain switching device by using a timing acquisition mode, such as: the current service bearing bandwidth of the equipment;
and 2.5, the management control system maintains the real-time state of the access equipment and performs unified display management on the acquired state of the cross-domain switching equipment.
Thirdly, the cross-domain service terminal system sets a cross-domain service data sending target as a management control system through configuration, so that the cross-domain service data is subjected to service landing in the management control system;
fourthly, the management control system distinguishes services (such as non-real-time unidirectional service, non-real-time bidirectional service, real-time bidirectional service and the like) of the landing service and finds out the corresponding IP set of the cross-domain switching equipment. The concrete mode is as follows:
4.1 the management control system can analyze the service type of the cross-domain data through the IP triple (protocol, source port and target port) or data format of the landing data, and the classification and division of the service are related through the service type;
4.2 the management control system obtains the IP address set of all the access cross-domain devices under the classification from the real-time state of the current uniformly managed access cross-domain switching device according to the classification and division of the service, and all the devices under the address set can provide cross-domain switching service for the service.
And fifthly, after acquiring the IP address set of the cross-domain switching equipment, the management control system selects the target equipment from the set. The management control system acquires the IP address of the target equipment by adopting service matching, performance priority and load idle priority when the target equipment is elected by analyzing the factors of the self state, the service load state, the physical link access state and the like of each equipment in the set;
sixthly, after the target IP is obtained, the management control system sends the landing cross-domain service data to target cross-domain switching equipment in an IP transmission mode, and the subsequent cross-domain switching transmission process is completed by the target equipment;
and seventhly, the target equipment informs the management control system of the transmission results, such as transmission success and transmission failure, in a real-time mode, and the management control system acquires the working stability and reliability of the current access cross-domain switching equipment in the mode and provides election reference for later-period resource allocation.
The invention has the beneficial effects that: the invention realizes the dynamic allocation of the cross-domain switching resources by uniformly managing the cross-domain switching resources through the management control system, can ensure that an administrator can uniformly manage both from the service perspective and the cross-domain switching equipment management perspective, and greatly improves the manpower maintenance cost of the cross-domain transmission system and the equipment deployment service load utilization rate.
