CSS technology assists Huawei enterprise network switches

Previously, the Huawei virtualization VS technology is actually the 1: N technology. Now I want to introduce another technology of the Huawei enterprise network data switch: 2: 2 CSS cluster exchange technology. The earliest cluster exchange technology in the Huawei enterprise network market was implemented through the 9300 switch. As a virtualization technology in the enterprise network market, Huawei's biggest feature is that the cluster Exchange Board is directly built on the main control board, it not only saves business boards, but also increases bandwidth. The high bandwidth of GB surprised the performance. Now let's take a look at what new breakthroughs we have made in the industry market in the field of DT pass through years of experience in the field?

First, let's take a look at what CSS technology is? A cluster switch system connects multiple switches supporting clusters to form a more powerful switch. What are the characteristics of CSS?

1. Multiple virtual switches: CSS acts as a logic switch, with control plane in one and unified management.

2. Integration of forwarding planes: in CSS, the devices in the house are integrated with the forwarding plane. The forwarding information is shared and synchronized in real time.

3. Cross-device link aggregation: Links of physical devices across CSS are aggregated into a ETH-TRUNK port for interconnection with downstream Devices

So many features have been mentioned. where do our network managers feel about our operation?

1. Simplified operation: the entire CSS is managed as a switch, which simplifies O & M and reduces Opex;

2. High Reliability: one device in CSS is faulty. Other devices can take over the control and forwarding of CSS to avoid spof;

3. Loop-Free Network: link aggregation across devices. When CSS is interconnected with other devices, loops are naturally avoided;

4. Link balancing: Cross-device link ECMP, 100% network link and bandwidth utilization;

In my opinion, let's look at the deployment and features of CSS.

CSS deployment features:

In the past, we had to use the Spanning Tree Protocol for multi-link deployment. The advantage was line backup. When a link went wrong, another link would be taken over. What would happen to us, that is, if you have two links and only one is in the active State and has a hot standby mechanism of, you cannot completely use the link. After using CSS technology, the spanning tree can be saved, at the same time, the bandwidth of the 1 + 1 link can be used better in the link, and hot backup can be performed at the same time. When a link is faulty, the other one can be taken over smoothly, at ordinary times, 1 + 1 is used to back up each other when an exception occurs. This is the network change that CSS cluster technology brings to us. In the future of the flat network trend, CSS cluster technology will surely have another impact on the network. As a leader in CSS clustering technology, Huawei will surely bring us another change.
