Spirent Landslide 18.8 Release Available For Download


Landslide 18.8 is now available for download on the Spirent customer support website.

As NEMs and Carriers continue their fast track towards deploying the first commercial 5G SA network, one of the critical barriers to overcome will be the correct interconnection with legacy networks to guarantee mobility, services’ coverage and offloading. To aid this tremendous effort, release 18.8 continues Landslide’s strategic feature set alignment by enhancing mobility testing support with continuous 5G VoNR to VoWifi handovers, plus Mobility Registration for 4G to 5G after EPS Fallback. Furthermore, the Service Based Architecture library of testcases is enhanced in Landslide 18.8 with the new SMSF network function.

Cloud infrastructure providers are making inroads into mobile networking initially with cloud hosted core functions for private LTE. They are now moving towards MEC and even hosting their systems in carrier data centers. This Landslide release adds support for Amazon Web Services and enables testing of NFs in the AWS Cloud or Outposts infrastructure, as well as testing the performance and scale of networks which include core elements running in AWS.
