       ETSI SDG OpenSlice and OpenCAPIF:



       Transforming the Telecom


       Standardization Landscape





       Within  ETSI,  renowned  for  developing  standards  that  drive  technological  innovation,  the  Software
       Development  Group  (SDG)  is  a  new  type  of  group  tailored  for  collaborative  software  development.
       Two significant initiatives under this group are OpenSlice and OpenCAPIF, which are set to revolutionize the
       telecom industry by enhancing interoperability, flexibility, and scalability in network services.


       OpenSlice:
       Network Slice as a Service


       OpenSlice   is   an   open-source    Network  slices  in  OpenSlice  are   for accessing and designing services,
       Operations  Support  System  (OSS)   described  according  to  the  GSMA   and  the  NFV  portal  for  managing

       OpenCAPIF:
