find a list of urls on the localhost for the service, and then round robin in the
list to pick up one.
Currently, this load balance is only used if you deploy the service as standalone
java process on data center hosts. We need to find a way to identify two VMs or two
docker containers sitting on the same physical machine in the future to improve it.
It is also suitable if your services are built on top of light-hybrid-4j and want
to use the remote interface for service to service communication.

... | Writes the given int value (32bit, 4 bytes) to the given position in little endian
byte order. This method's speed depends on the system's native byte order, and it
is possibly slower than {@link #putInt(int, int)}. For most cases (such as
transient storage in memory or serialization for I/O and network),
it suffices to know that the byte order in which the value is written is the same as the
one in which it is read, and {@link #putInt(int, int)} is the preferable choice.
@param index The position at which the value will be written.
@param value The int value to be written.
@throws IndexOutOfBoundsException Thrown, if the index is negative, or larger than the segment
