Reference Point System Architecture vs Service Based Architecture

Shares

​Let’s start with simple definitions for these two type of architectures​ Reference Point architecture consist of a set of Network Elements (NE) which use point to point interfaces to inter-connect those Network Elements.Signalling procedures are specified for each point to point interface.  This architecture type can lead to repetition within the specifications if same signalling procedure […]
