Network Load Balancer
Load Balancer
The DataReel load balancer (LB) is a software based TCP load balancing solution designed to run on Linux operating systems. The DRLB project was designed to handle any type of TCP connection, acting as a front end server distributing high volumes of TCP connections to multiple back end servers. Load balancing protects your back end servers from saturation when you have more clients connections than any one server can handle. The DRLB server can be used as a high availability resource to provide seamless server fail over. In signal server environments the DRLB server can provide connection limits and cached buffing.
Features
- Round robin: Distribute connections equally to server nodes in order received.
- Weighted: Distribute connections based on a weight value assigned to each server node.
- Distributed: Distribute connections based on a load percentage assigned to each server node.
- Assigned: Assign connections to specific server nodes with the option to use round robin, weighted, or distributed load balancing for fail over and unassigned connections.
- Connection throttling: Prevent server saturation by throttling connections based on preset connections values or number of connection per second.
- Statistics: Option to log connection information and monitor connections per second in real time.
- Connection limits: Option to set connections per server node or all server nodes.
- Caching: Buffer server connections with option to set custom buffer sizes.
- Buffer overflow detection: Option to detect buffer overflows for specific applications.
