Sarance's 100G and 40G Ethernet cores have already been licensed by major networking companies and have gone through rigorous testing by passing live Internet traffic ... The adoption of the same cores by a major test equipment vendor like Spirent further validates the robustness of Sarance IP and provides the quickest path for network equipment vendors to get their products to the market. We're excited to be working with Spirent and to accelerate the deployment of 100G and 40G equipment.
