Round Robin is an algorithm that selects servers sequentially. Accordingly, the Load Balancer will start from server number 1 in its list corresponding to the first request. It then moves down the list in order and starts again at the top when it reaches the last server. What are the disadvantages of the Load Balancing – Round Robin algorithm? When there are 2 consecutive requests from the user, they can be sent to 2 different servers. This wastes time creating additional connections with the second server while the first server can also respond to the information the user needs. To solve this, round robin is often implemented in conjunction with session maintenance methods such as cookies. What is the Load Balancing – Weighted Round Robin algorithm? Similar to the Round Robin technique, WRR also has the ability to process according to the configuration of each target server. Each server is evaluated by an integer (weight value – default value is 1).
A server with twice the processing capacity of another server will be given a higher number and receive twice as many requests from the load balancer. What are the disadvantages of the Load Balancing – Weighted Round Robin algorithm? Weighted Round Robin causes dynamic load imbalance if the load of requests continuously changes over a large period of time. What is Load Balancing – Dynamic Round Robin (DRR) algorithm? The DRR algorithm works almost the same as the WRR algorithm. The difference is that the weighting here is based on continuous server checks. Therefore the weights Loan Phone Number List continuously change. Choosing a server will be based on many aspects in analyzing the server's performance in real time. For example: the number of connections currently available on the server or the fastest responding server, ... This algorithm is usually not implemented in simple balancers. It is commonly used in F5 Network's load balancing products. What is the Load Balancing – Fastest algorithm? This is an algorithm based on calculating the response time of each server (response time). This algorithm will choose the server with the fastest response time.
The response time is determined by the time interval between the time a packet is sent to the server and the time the response packet is received. This sending and receiving will be taken care of by the load balancer. Based on the response time, the load balancer will know which server to direct the next request to. The Fastest algorithm is often used when servers are in different geographical locations. So whichever server the user is near, that server's response time will be the fastest. Finally, that server will be selected for service. What is the Load Balancing – Least Connections algorithm? Requests will be routed to the server with the fewest connections in the system. This algorithm is considered a dynamic algorithm, because it must count the number of active connections of the server. Least Connections has good performance. Even when the load of the connections varies over a large range. Therefore, using RC will overcome the disadvantages of Round Robin.
