jetNEXUS ALB-X Features:
Layer 7 Load Balancing
Basic load balancer only solutions are today lacking much of the functionality and flexibility required by demanding business applications. jetNEXUS Application Delivery Controllers feature unbeatable high performance layer 7 server load balancing – that is, the provision of intelligent load balancing of traffic and visibility of that traffic.
What is Layer 7 Load Balancing?
Layer 7 load balancing is fundamental to application delivery control, operating, as it does, at the application protocol level. By operating at the application protocol level, the load balancer understands the type of data it is processing such as HTTP and HTTPs. This allows for many features that are not possible at lower level load balancing such as URL switching, Cookie based persistence, Request scanning etc. This content-aware load balancing strategy enables application performance optimisation and resilience across the application layer.

All jetNEXUS ADC devices have the following load balancing methods:
Round Robin Load Balancing
Round Robin is the most basic type of load balancing strategy. All web servers simply take turns with the incoming requests.Least Number of Connections Load Balancing
The least number of connections is the most popular non persistent load balancing method. This method takes into account the servers current work load and will allocate new requests to the least busy server. IP Sticky - Persistent Load Balancing
IP sticky is the most basic persistent load balancing technique. This method will simply direct the same user back to the same web server based on their IP address. Cookie Sticky - Persistent Load Balancing
This is the most advanced and popular method of persistent load balancing. The client is issued a cookie on the first connection with the internal server ID. Subsequent requests will read the cookie and redirect the request to the appropriate web server. Weighted Load Balancing
Weighted load balancing takes into account the fact that some servers have more capacity than others. The weighted option allows you to define the relative performance of particular web servers. This weight will influence the number of request the servers is sent to process.
