[0005] From the perspective of the access server, the service quality of the service server depends not only on the processing capability of the service server itself, but also on the network bandwidth between the two, network delay, and changes in the external environment of the service server. The existing load balancing algorithm only distributes request packets in proportion to the maximum quota value of the business server, that is, only considers the processing capacity of the business server itself, and when the network leading to the business server is congested, packet loss occurs, or the business server When its own performance degrades, if the access server still distributes request packets according to the ratio of the maximum quota value, this will cause load balancing between business servers cannot be truly achieved

Embodiment Construction
[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0021] In the self-adaptive load balancing implementation method proposed by the present invention, the access server selects the target service server of the request packet by using the currently available quota value dynamically changed according to the service quality of the service server, so as to realize load balancing.
[0022] The method provided by the invention is described below:
[0023] figure 2 The flow chart of the method provided by the embodiment of the present invention. Such as figure 2 As shown, the process may include the following steps:
[0024] Step 201, the access server receives the request packet.
[0025] Step 202, the access server selects the service server from the cluster according to the current available quo...

The invention provides a self-adaption load balancing realizing method and an access server. According to the method, after the access server receives a request packet, the access server selects an objective service server of the request packet from a cluster according to current usable quota values of all service serves in the cluster and the principle that the bigger a current usable quota value is, the bigger the probability of the objective service server of the request packet is, and then the request packet is sent to the selected objective service server, wherein the current usable quota value of each service server is determined by service quality of the service server.
Description
technical field [0001] The invention relates to network communication technology, in particular to a self-adaptive load balance realization method and an access server. Background technique [0002] At present, connecting multiple business servers to form a cluster is widely used because it can improve data processing capabilities and service capabilities. see figure 1 , figure 1 Schematic diagram of the architecture serving an existing cluster. exist figure 1 In the above, each business server in the cluster will install a configuration client software, and regularly report its working status to the server called the configuration center (referred to as the configuration center server). When the configuration center server does not receive the When the status of a business server is reported, it is considered that the business server has failed, and the business server is excluded from the cluster. When the configuration center server receives the work status reported b...
