CGN/BNG Performance Tests on Huawei NE8000 Platform

Learn from Luiz Puppin, a Huawei specialist, how to perform a technical analysis of the Forwarding Performance tests carried out in a laboratory environment with the Huawei NE8000 platform, validating the equipment’s ability to operate as an integrated BNG+CGN at high load. The tests sought to verify: Purpose of Performance Tests The aim was to prove that the Huawei solution can be sustained: These features are essential for ISPs and operators with a high concentration of subscribers behind CGNs. Architecture used The topology used connects: Methodology 5. Evidence and Results Below are the verifications taken directly from the test file. 5.1. Subscribers successfully authenticated The report confirms the simultaneous authentication of thousands of PPPoE subscribers: The total validated was: 5.2. Creation of 32 million NAT sessions The DUT has reached the scalability limit set by the manufacturer: In other words, the equipment was able to withstand 32 million simultaneous streams without any noticeable degradation. 5.3. Sustained Traffic at 50 Gbps – No Packet Loss In other words: 5.4. Bidirectional traffic 50 Gbps (25G + 25G) The laboratory validated simultaneous upstream and downstream operation: Again, with zero packet loss: 5.5. CPU stability The CPU remains at stable levels, without reaching critical limits. 5.6. Completion of Performance Tests Based on the evidence, it is possible to conclude that: Therefore, the platform demonstrates real capacity to operate CGN/BNG in large-scale environments, with a high volume of traffic and a high density of subscribers.
