Load Balancing Special Services
Document ID: RDWR-ALOS-V2900_AG1302 325
4. Create a group to load balance the SIP proxy servers.
5. Define the group metric for the server group. TCP-based SIP load balancing supports all metrics.
For example, set the metric to minmisses.
6. Define the health check for the group. The health check is TCP for TCP-based SIP load balancing.
7. Configure a virtual server for Layer 4 SIP load balancing.
8. Configure the SIP service 5060 for Virtual Server 1.
9. Configure the SIP TLS service 5061 for Virtual Server 1.
10. Enable DAM.
Note: Distribution of sessions between servers is achieved using the minmisses hash method
and is not always even. Call distribution can be improved by increasing the number of Call ID
bytes that are used as input to the hash function. For example:
>> Virtual Server 1 sip Service# sip/hashlen 16
>> Real server 2# ena
(Enable Real Server 2)
>> # /cfg/slb/real 3/rip 10.10.10.3
(Define address for MCS 3)
>> Real server 3# ena
(Enable Real Server 3)
>> # /cfg/slb/group 100
(Define a group)
>>Real Server Group 100# add 1
(Add Real Server 1)
>>Real Server Group 100# add 2
(Add Real Server 2)
>>Real Server Group 100# add 3
(Add Real Server 3)
>>Real Server Group 100# metric minmiss
>>Real Server Group 100# health tcp
>> # /cfg/slb/virt 1
(Select Virtual Server 1)
>>Virtual Server 1# vip 40.40.40.100
(Set IP address for the virtual server)
>>Virtual Server 1# virt ena
(Enable virtual server)
>> # /cfg/slb/virt 1/service 5060
(Add the SIP service for Virtual Server
1)
>> # /cfg/slb/virt 1/service 5060 Group 100
(Add the real server group to the
service)
>> # /cfg/slb/virt 1/service 5061/Group 100
>> # /cfg/slb/adv/direct ena
