LB Algoritm
The algorithm that will be distributed to Backend Services is selected.
- Round Robin > The load balancing is done independent from the dynamic loads (weights) of the vServices.
- Weighted Round Robin > The load balancing is done based on the dynamic loads (weights) of the vServices.
- Least Connection > The servers that currently have less connections get the priority. Recommended for servers with long session times such as LDAP and SQL.
- Locality Based Least Connection > As long as the server is not overloaded, client traffic requesting the same IP is distributed to the same server. In case of overload, the distribution is made to the server with least connection.
- Weighted Least Connection > Distribution is made to the pool with the fewest connections to the server weight.
- Source Hash > Distribution is made according to the hash value of the source IP.
- Destination Hash > Distribution is made according to the hash value of the target IP.
- L4 Persistence
Persistance period is entered. If persistant is not desired, 0
should be entered as a value.
- SIP Persistence
