round robin load balancing algorithm

test by the core developers and users shows that it works well: The request connection is now evenly distributed. There is also a plan to turn the selection algorithm into a configurable or plugin-based approach.If you want to fall back to the previous assignment method, you can set the Cluster.schedulingpolicy:var cluster = require (' cluster '); // Set This before calling and other cluster functions. Cluster.schedulingpolicy = cluster. Sched_none;c

How does the Nginx load balancer do it? In fact, nginx load balancing has a lot of methods can be achieved, the following I will give you a concrete introduction of the Nginx load balancing algorithm, including polling, Weight,ip_

the original round robin algorithm, added a program for collecting dynamic weights and fed back it to the Load balancer's scheduling system in real time. Practice has proved that the use of dynamic balancing has improved the overall throughput of the cluster system, especially when the performance of each node in the

thrown load balancing in as a feat Ure. Round Robin: Round Robin passes each new connection request to the next server on line, eventually distributing C Onnections evenly across the array of machines being load balanced. Round

repeatedly, the algorithm is able to flow (session) to ensure that traffic from the same client can be processed all the time on the same server.6.URL HashAn algorithm that forwards requests sent to the same URL to the same server by managing a hash of the client's request URL information.The method of load balancing

What is load balancing Load balancing, the English name is load Balance, refers to the multiple servers in a symmetric way to form a collection of servers, each server has an equivalent status, can be provided separately from external services without the assistance of othe

The load master can provide many kinds of load balancing methods, that is, we often call the scheduling method or algorithm:Round robin (Round Robin)This method loops the received requests to each machine in the server cluster, which is the active server. If this is the case

In the Internet Distributed system, many services are data storage-related, mass access, direct access to storage media is not resistant, need to use Cache,cache cluster load balancing algorithm becomes an important topic, here to the existing load balancing

Model has a corresponding load balancing strategy for different application requirements. The advantages and disadvantages of the load balancing strategy and its implementation are two key factors: Load balancing

General scenarios and application scenarios of load balancing in summaryPolling schedulingTo request scheduling different servers in order of polling; When implemented, the server is generally weighted; this has two benefits: Performance differences for servers can be assigned different loads; When a node needs to be removed, it is only necessary to set its weight to 0; Advantages: Simple
