“Structuring a real world test” Spirent and Crossbeam were recently part of a major collaboration to define and document a test methodology that could accurately assess the performance of a firewall on the demanding Gi(3G) or SGi(4G-LTE) interface of a mobile operator's network.  Working to design this test were EANTC (the European Advanced Networking Test Center, internationally recognized for its test expertise), Heavy Reading (a provider of deep analysis of telecom trends), S...
