My purely technology oriented take on that is that telecom manufacturers had really embraced the idea “everything is IP over Ethernet” during the development of LTE and then during first deployments found out, that such approach does not realy work on real networks with mixed generations of both infrastructure and user terminals (this is the reason for existence of VoLTE). And on other hand everybody found out that “computer networking” hardware is commodity thing that is cheap. So, Huawei knows that they need something which is not IP and tries to make hardware that supports it commodity product instead of niche telco weirdness by trying to push their thing as end-all solution to everything networking. In fact, from this PoV this is somewhat reminiscent of late 90's and ATM.
