4.5.9.4 Service record
Service records (SRV record in DNS terminology) offer the possibility of storing information on available
system services in the DNS. In UCS service records are used amongst other things to make LDAP servers
or the domain controller master known domain-wide.
A service record must always be assigned to a forward lookup zone and can therefore only be added to a
forward lookup zone or a subordinate container.

Service (*)
The name under which the service should be reachable.
Protocol (*)
TCP and UDP are available.
Priority (*)
A whole number between 0 and 65535. If more than one server offer the same service, the client will
approach the server with the lowest priority value first.
Weight (*)
A whole number between 0 and 65535. The weight function is used for load balancing between
servers with the same priority. When more than one server offer the same service and have the
same priority the load is distributed across the servers in relation to the weight function.
Example: Server1 has a priority of 1 and a weight function of 1, whilst Server2 also has a priority
of 1, but has a weight function of 3. In this case, Server2 will be used three times as often as
Server1. The load is measured depending on the service, for example, as the number of requests or
connection.
Port (*)
The port where the service can be reached on the server (valid value from 1 to 65535).
Server (*)
The name of the server on which the service will be made available, as a fully qualified domain name
with a full stop at the end or a relative domain name.
