If a service is marked as Out Of Service, it will continue to serve existing requests but will not accept new ones or connections. If the configured persistence applies to a down service, the appliance selects a new service using load balancing methods, and the new service becomes persistent for subsequent client requests. Once the server has been selected, the load balancing algorithms are overridden if persistence is enabled. The appliance then selects a server using the defined load balancing mechanism, however all subsequent requests from the same client are forwarded to the same server. ![]() If you want to keep the states of connections on the servers represented by that virtual server, you must configure persistence on that virtual server. Which service currently is receiving the fewest packets.įewest active connections and the lowest average response time. Which service currently has the fewest bandwidth constraints. Which load balanced server has the fastest response time right nowĪ hash of the source and destination IP addresses.Ī hash of the client’s IP address and port. After that service is selected for a connection, it moves to the bottom of the list. Which service is at the top of a list of services. Which service has the fewest client connections right now. The following load balancing methods are supported: LEASTCONNECTION The methodical and efficient distribution of network or application traffic across multiple servers in a server farm is referred to as load balancing. Each load balancer sits between client devices and backend servers, receiving and distributing incoming requests to any server that can fulfill them. Virtual servers are used to map LLB services, and those services are then represented for each individual link (router or next hop). Virtual servers configured on the appliance provide connection points that clients use to access the applications behind the appliance in a typical installation. In case of load balancing, where service represents a server, a service in LLB represents a router or the next hop. While services are typically combined with virtual servers, a service can still manage application-specific traffic in the absence of a virtual server. ![]() Services are applications that run on a server. Configure reverse NAT (RNAT) and backup links to personalize your system.īelow are the different components for configuring Link Load Balancing: The default monitor is PING, although setting up a transparent monitor is advised. Source IP address-based persistence, destination IP address-based persistence, and source IP and destination IP address-based persistence are all options. There are two Link Load Balance services available with 192.168.30.x1 and 192.168.30.x2, and traffic data travels through the efficient internet service provider, as shown in the example below,įor connections to be sustained on a specific link, you can optionally configure persistence. You can customize a basic setup for your environment once it is operating. Services, virtual servers, monitors, routes, an LLB method, and persistence are all part of a basic configuration (optional). Configuring a basic setup with default parameters while configuring link load balancing is the most common scenario. The Citrix ADC appliance and the router are connected through a link. Outbound traffic is balanced via link load balancing (LLB) over numerous Internet connections offered by different service providers. ![]() The Citrix ADC appliance uses LLB to monitor and regulate traffic, ensuring that packets are sent over the best possible network. ![]()
