Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.
Load balance (also called load sharing) is established on the existing network structure, load (work task) is balanced and then distributed to a plurality of operation units for execution, for example, distributed to a Web server, an FTP server, an enterprise key application server and other key task servers for execution, so as to jointly complete the work task. The load balancing method can expand the bandwidth of network equipment and a server, increase the throughput, strengthen the data processing capacity of the network and improve the flexibility and the availability of the network.
The early load balancing method has relatively single mode for selecting the server and is not flexible enough. For example, the polling method is to arrange the servers into a sequence and distribute the load to them in turn. The source address algorithm records the source address accessed by the client based on the polling algorithm, and the client request with the same source address is processed by the same server. A minimum connection algorithm was developed to record the number of connections currently existing for each server and assign new requests to the server with the smallest number of connections.
In the existing load balancing method, a weight value is set for most of the backend member servers. For example, a weighted round robin algorithm allows a user to set a weight value for each server by himself, with larger weights handling more requests. And the addition of the weight value enables the load balancing method to be more flexible.
However, when the current load balancing method is used for load balancing of data volume transmission at ultra-high-level, the balancing efficiency is low, expensive equipment needs to be purchased additionally for realization, and the cost is high.
In order to solve the above technical problems, the present application provides a virtual network resource service method as shown in the figure, which is applied to a data forwarding cluster as shown in fig. 2, where the data forwarding cluster includes an area sink node, an area load balancing node, an area transmission node, a system sink node, a system load balancing node, a system transmission node, a field sink node, a field load balancing node, and a cloud server; the method comprises the following steps:
step S11, the area aggregation node receives a plurality of department data streams of a specific geographic area;
the data forwarding cluster is suitable for data transmission of smart cities, the smart cities relate to data transmission of cross-fields, systems and departments, and the smart cities face application environments with wide fields, multiple systems and multiple departments. For example, the fields include various fields such as city management, social life, resource environment, industrial economy, special services and the like, and more specifically, the business systems in the city management field can be business systems such as government affairs, traffic, city management, security, fire fighting and the like; the business system in the social and civil field can be a medical, community, social security, education and other business system; the service system in the resource environment field can be an energy, environment-friendly, ecological and other service system; the business system in the industrial economic field can be business systems of tourism, finance, port, park, enterprise service and the like; the business system in the characteristic service field can be a city ecological service platform, a postdoctor management service platform, a scientific and technological enterprise management service platform, a self-service enterprise management platform and other business systems. More specifically, each business system further includes each department.
As shown in fig. 2, data transmission of departments and service systems in various fields of a smart city is ultra-massive, and the data forwarding cluster provided by the present application is embedded in data transmission systems of all the departments and service systems, so that load balancing is dispersed in data transmission processes of all the departments and service systems, and on one hand, flexibility of load balancing can be improved, that is, no matter whether a department is added or a department is deleted, the data transmission is very convenient and fast; on the other hand, load balancing is carried out on the department data flow with low data volume, the system data volume with medium data volume, the domain data volume with high data volume and the multi-domain data volume with ultra-sea level, so that the load balancing pressure is dispersed, and the load balancing efficiency is improved.
Specifically, according to the characteristics of urban distribution, city management, social and civil life, resource environment, industrial economy and characteristic services are involved in each administrative district and county of a city, and the closer the transmission distance is, the faster the transmission rate is during data transmission, so that in order to accelerate the data transmission manner, the city can be divided according to the geographical position, for example, the city can be divided according to administrative districts, and the department data streams of each department in an administrative district are all sent to the regional aggregation node. That is, the data received by the regional aggregation node is a data stream including each domain, each service system, and each department.
That is, the number of the area aggregation nodes for one city is plural, and the number may be specifically set according to the geographical area.
Step S12, the regional load balancing node selects a physical port from the regional transmission node according to the load balancing parameters of the multiple department data streams received by the regional sink node, and sends the multiple department data streams to the system sink node;
the number of the regional load balancing nodes is the same as that of the regional aggregation nodes, and the regional load balancing nodes correspond to the regional aggregation nodes one to one. And the load balancing node distributes a physical interface for the department data stream according to the load balancing parameter of the department data stream received by the regional sink node, so that the department data stream is transmitted to the system sink node.
Specifically, the load balancing parameter of the multiple department data streams is a transmission quality requirement;
step S12, where the regional load balancing node selects a physical port from the regional transmission node according to the load balancing parameters of the multiple department data streams received by the regional sink node, and sends the multiple department data streams to the system sink node, specifically including:
step S1201, the regional transmission node sorts the physical ports in the regional transmission node according to the transmission quality of the physical ports from high to low;
step S1202, when department data streams with transmission quality requirements exceeding a first preset quality threshold exist in the department data streams, the regional load balancing node sends the department data streams with transmission quality requirements exceeding the first preset quality threshold to the system aggregation node from a physical port with first transmission quality in the regional transmission node;
step S1203, when there is a department data stream whose transmission quality requirement is smaller than a first preset quality threshold and exceeds a second preset quality threshold in the multiple department data streams, the regional load balancing node transmits the department data stream whose transmission quality requirement is smaller than the first preset quality threshold and exceeds the second preset quality threshold from a physical port of a transmission quality second of the regional transmission node to the system aggregation node.
The transmission quality of the physical ports of the regional transmission nodes may be different, the transmission quality requirements of data streams of a plurality of departments may also be different, in order to better provide adaptive services for different departments and make the best use of the regional transmission nodes, the method divides the physical ports in the regional transmission nodes according to the transmission capacity (that is, the transmission quality), and sorts the physical ports according to the transmission quality from high to low.
Adaptively, classifying the plurality of department data streams according to transmission quality requirements of the department data streams, which may specifically include a first type: transmitting a department data stream whose quality requirement exceeds a first preset quality threshold; the second type: department data streams less than a first preset quality threshold and exceeding a second preset quality threshold; the third category and the fourth category may also be added according to specific requirements, which are not described herein again.
Sending the first type of department data stream to a system sink node through a physical port with first transmission quality; sending the second type of department data stream to a system sink node through a physical port of a second transmission quality; by analogy, the department data streams with different transmission quality requirements are sent to the physical ports with corresponding transmission quality grades for transmission, so that the utilization rate of the physical ports is improved, the data transmission efficiency is improved, and meanwhile, the load tasks of the physical ports are balanced.
Before the regional load balancing node sends the department data stream whose transmission quality demand exceeds a first preset quality threshold value from the physical port of the regional transmission node where the transmission quality is first to the system aggregation node, the method further includes:
when the transmission task quantity of a physical port with first transmission quality in the regional transmission node exceeds a first preset transmission threshold value of the physical port with first transmission quality in the regional transmission node, the regional load balancing node sends a department data stream with transmission quality requirement exceeding the first preset quality threshold value from a physical port with second transmission quality in the regional transmission node to the system aggregation node;
and when the transmission task quantity of the physical port for transmitting the quality second in the regional transmission node exceeds a second preset transmission threshold value of the physical port for transmitting the quality second in the regional transmission node, the regional load balancing node sends the department data stream with the transmission quality requirement exceeding the first preset quality threshold value from the physical port for transmitting the quality third in the regional transmission node to the system aggregation node.
In order to avoid the situation that the physical port with the high transmission quality level is busy and the physical port with the first transmission quality level is idle, on the basis of the steps S1201 to S1203, if a certain physical port exceeds the preset transmission threshold of the certain physical port, the data stream which is originally sent to the physical port is transferred to the physical port with the next transmission quality level for sending, so as to further balance the transmission task amount of each physical port under the condition of ensuring the transmission quality.
Step S13, the system sink node receives the department data streams and classifies and packs the department data streams according to the service system to which the department belongs to form a plurality of service system data streams;
because the data streams of the multiple departments are obtained by each field, each service system and each department in a specific geographic area, in order to better manage the data streams, the system aggregation node classifies the data streams of the multiple departments according to the service systems to which the data streams belong, and packs the data streams of the departments of the same service system together to form the data streams of the corresponding service system.
Step S14, the system load balancing node selects a physical port from the system transmission node according to the load balancing parameters of the multiple service system data flows received by the system sink node and sends the multiple service system data flows to the domain sink node;
similarly, the system transmission node sequences the physical ports in the system transmission node from high to low according to the transmission quality of the physical ports;
when a service system data stream with a transmission quality requirement exceeding a third preset quality threshold exists in the service system data streams, the system load balancing node sends the service system data stream with the transmission quality requirement exceeding the third preset quality threshold to the field aggregation node from a physical port of the system transmission node, which transmits the quality first;
and when the service system data streams with the transmission quality requirements smaller than a third preset quality threshold and larger than a fourth preset quality threshold exist in the service system data streams, the system load balancing node sends the service system data streams with the transmission quality requirements smaller than the third preset quality threshold and larger than the fourth preset quality threshold to the field aggregation node from a physical port of a transmission quality second in the system transmission node.
Similarly, when the transmission task quantity of the physical port of the first transmission quality in the system transmission node exceeds a third preset transmission threshold of the physical port of the first transmission quality in the system transmission node, the system load balancing node sends the service system data stream of which the transmission quality demand exceeds the third preset quality threshold from the physical port of the second transmission quality in the system transmission node to the domain aggregation node;
and when the transmission task quantity of the physical port of the second transmission quality in the system transmission node exceeds a fourth preset transmission threshold value of the physical port of the second transmission quality in the system transmission node, the system load balancing node sends the service system data stream of which the transmission quality requirement exceeds the fourth preset quality threshold value from the physical port of the third transmission quality in the field transmission node to the field aggregation node.
Step S15, the domain sink node receives the multiple service system data streams, and classifies and packages the multiple service system data streams according to the domains to which the service systems belong, so as to form multiple domain data streams;
since the multiple service system data streams can be further classified according to the fields, in order to better manage the data streams, the field sink node classifies the multiple service system data streams according to the fields to which the multiple service system data streams belong, and packs the service system data streams in the same field together to form corresponding field data streams.
Step S16, the domain load balancing node selects a physical port from the domain transmission node according to the load balancing parameters of the domain data streams received by the domain sink node to send the domain data streams to the cloud server;
similarly, the domain transmission node sorts the physical ports in the domain transmission node according to the transmission quality of the physical ports from high to low;
when a domain data stream with a transmission quality requirement exceeding a fifth preset quality threshold exists in the plurality of domain data streams, the domain load balancing node transmits the domain data stream with the transmission quality requirement exceeding the fifth preset quality threshold from a physical port of a first transmission quality in the domain transmission node to the cloud server;
and when the domain data streams with the transmission quality requirements smaller than a fifth preset quality threshold and exceeding a sixth preset quality threshold exist in the plurality of domain data streams, the domain load balancing node sends the domain data streams with the transmission quality requirements smaller than the fifth preset quality threshold and exceeding the sixth preset quality threshold to the cloud server from the physical port of the second transmission quality in the domain transmission node.
Similarly, when the transmission task quantity of the physical port of the first transmission quality in the domain transmission node exceeds a fifth preset transmission threshold of the physical port of the first transmission quality in the domain transmission node, the domain load balancing node sends the domain data stream of which the transmission quality demand exceeds the fifth preset quality threshold to the cloud server from the physical port of the second transmission quality in the domain transmission node;
and when the transmission task quantity of the physical port for transmitting the quality second in the domain transmission node exceeds a sixth preset transmission threshold value of the physical port for transmitting the quality second in the domain transmission node, the domain load balancing node sends the domain data stream with the transmission quality requirement exceeding the sixth preset quality threshold value to the cloud server from the physical port for transmitting the quality third in the domain transmission node.
And step S17, the cloud server receives and stores the plurality of domain data streams.
Specifically, the regional transmission node includes a common physical port and a standby physical port;
the regional load balancing node selects a physical port from the regional transmission node according to the load balancing parameters of the department data streams received by the regional sink node, and sends the department data streams to the system sink node, and the method specifically includes:
the regional load balancing node selects a common physical port from the regional transmission node according to the load balancing parameters of the department data streams received by the regional sink node and sends the department data streams to the system sink node;
and when the common physical port of the regional transmission node is unavailable, the regional load balancing node replaces the unavailable common physical port with a standby physical port and sends the department data streams to the system aggregation node from the standby physical port.
The standby physical port is configured for the common physical port, when the common physical port fails, data stream transmission can be performed through the standby physical port, the stability of the data forwarding cluster can be improved, and meanwhile, the situations of data loss and data delay transmission are avoided.
Similarly, the system load balancing node selects a common physical port from the system transmission node according to the load balancing parameters of the plurality of service system data streams received by the system sink node to send the plurality of service system data streams to the domain sink node;
and when the common physical port of the system transmission node is unavailable, the system load balancing node replaces the unavailable common physical port with a standby physical port and sends the service system data streams to the domain aggregation node from the standby physical port.
Similarly, the domain load balancing node selects a common physical port from the domain transmission nodes according to the load balancing parameters of the domain data streams received by the domain aggregation node to send the domain data streams to the cloud server;
and when the common physical port of the domain transmission node is unavailable, the domain load balancing node replaces the unavailable common physical port with a standby physical port and sends the domain data streams to the cloud server from the standby physical port.
