For each host remote procedures are uniquely identified by the triple (program number, version number, procedure number). GDS is using different rpc program numbers for different services. It is assumed that only one service of any given type can be run on a single host. However, multiple servers can run on multiple hosts (CPUs). To avoid potential conflicts the numbers used by GDS should not used for any other rpc service within LIGO. The following assignment of rpc services with program and version numbers is used by gds:

interface	program num.	version num.
test point	0x31001001	1
arbitrary waveform generator	0x31001002	1
diagnostics data server	0x31001003	1

The assignement of procedure number is maintained by the corresponding services.
