High-Density 10GE Infrastructure Network SolutionThe infrastructure network of the 10GE campus network solution uses multi-layer, modular, redundant architecture.10GE campus infrastructure network architecture• Multi-layer design: The network consists of a core layer, an aggregation layer, and an access layer. Each layer has clearly defined
functions and a stable topology, making the network easy to expand and maintain.
• Modular design: Each module corresponds to an enterprise department, facilitating fault location. Network topology changes in one department do not affect other departments.
• Redundant design: A two-node redundant design makes the network more reliable without significantly increasing the maintenance workload. Too much redundancy is difficult to maintain.
Large and medium scale campus networks use the three-layer architecture described here. Small-scale networks use a two-layer architecture that combines the core layer with the aggregation layer.Recommended networking schemesHuawei offers high performance core, aggregation, and access switches, all with high port densities: • CE12800 and S9700 can be deployed at the core layer. The CE12800 provides a maximum of 288 40GE ports. The 40GE port density is more than 3 times the industry average.
• S9700 and S7700 can be deployed at the Aggregation layer. The S9700 and S7700 provide a maximum of 480 10GE ports. The 10GE port density is more than 3 times the industry average.
• Access switch S5700 provides a maximum of 64 GE ports, much more than the average of 52 GE ports on access switches of other vendors.Comparison of port densities on Huawei and non-Huawei switches
Green NetworkAccording to IDC (International Data Corporation), energy consumption costs account for 25% of hardware operating expenses. Planning for energy efficiency is a key consideration of enterprise network design.
Traditional Ethernet technologies consume much power even no service traffic is being transmitted. Energy Efficient Ethernet (EEE) defines a Low Power Idle (LPI) state and monitors service traffic in real time. A link that is not transmitting traffic enters the LPI state to save power. EEE reduces the energy consumption by 30%.EEE reduces power consumption by 30%Huawei switches use Huawei's patented device sleeping technology. Huawei switches can set idle ports to sleeping mode and adjust chip power consumption based on port traffic volume. If all ports enter the sleeping state, chips also enter a deep sleep state. Miercom (a famous test and certification firm) tested power consumption of Huawei S5700-LI switch and similar switch from other vendors. The test results showed that Huawei S5700-LI consumes 69% less power than similar switches.Power consumption comparison between Huawei S5700-52P-LI and a similar productA Huawei switch that supports device sleeping and EEE can result in considerably lower powers costs. The example here shows power consumption of a Huawei S5700-52P-LI and a competitor's switch deployed in a typical office demonstrates. Company work hours are from 7:00 a.m to 7:00 p.m and five days a week (see Figure 8). The Huawei S5700-52P-LI switch uses 2876 Wh less per week (5952 – 3076 = 2876 W) than the competitor's switch. Annual power consumption decreases by about 150 kWh (2876 x 365/7≈150 kW). Use of Huawei switches results in considerable savings.Power consumption of Huawei switches and non-Huawei switches
