It is not just the network hardware and software that are opening up, sometimes painfully, after years of proprietary systems. Even at chip level, there are pressures to open up the architectures, with open source initiatives targeting processors (as with RISC-V) and even modems. This is prompting response from the semiconductor giants as they go through their own process of adapting to a cloud and 5G world. Intel has started to work closely with some open initiatives and to drive its interfaces as standards in areas like chiplets. Xilinx has announced an open software development platform to make its FPGAs more deployable and interoperable with other vendors’ components.
