Mikrotik pcc load balancing with pppoe server network in this network mikrotik router s 1st interface ether1 is connected to isp1 having ip address 192 168 30 2 30 and 2 nd interface ether2 is connected to.
Load balancing servers network diagram. Basic load balancing topology. When discussing enterprise website hosting load balancing is a topic that comes up often. We ve previously discussed how load balancing can be implemented but we wanted to take a closer look at some of the specific advantages it can provide. To configure a load balancing and link redundancy network with mikrotik routeros i am following a network diagram like below image.
The scenario diagram would be the same with the exception that the load balancer would be essentially a switch load balancing by modifying l2 frames. The network load balancing nlb feature distributes traffic across several servers by using the tcp ip networking protocol. Network load balancing commonly referred to as dual wan routing or multihoming is the ability to balance traffic across two or more wan links without using complex routing protocols like bgp. This capability balances is network sessions like web email etc.
By combining two or more computers that are running applications into a single virtual cluster nlb provides reliability and performance for web servers and other mission critical servers. The virtual server selects the service and assigns it to serve client requests. But i will only focus on the routed mode as it is the most common and more easy to understand. As shown in the following high level diagram an internal tcp udp load balancing service has a frontend the forwarding rule and a backend the backend service and instance groups.
There are a number of specific types of load balancing you might need to consider for your network including sql server load balancing for your relational database global server load balancing for troubleshooting across multiple geographic locations and dns server load balancing to ensure domain name functionality. To be clear what we re discussing here is hardware load balancing of traffic to two or more web servers rather than load balancing as it relates. Load balancer is a network device that facilitates horizontal clustering where multiple servers are configured to perform the same function on the network the load balancing functionality may be provided by software or a hardware device in one of two ways. In the diagram load balancing is used to manage traffic flow to the servers.
Consider a scenario where the services service http 1 and service http 2 are created and bound to the virtual server named vserver lb 1. Load balancing refers to efficiently distributing incoming network traffic across a group of backend servers also known as a server farm or server pool. Distributed each node in the cluster receives every packet destined for the cluster.
