Functions

Application

The LE0DG48TBC00 and LE0DG48SBC00 of the S9300X have a large buffer capacity. The 1.25 GB buffer capacity on each port achieves 200 ms buffering, which prevents packet loss caused by traffic bursts on a network. When the network is congested and traffic bursts occur, the large-buffer cards can effectively buffer traffic on ports. The large buffer capacity, combined with QoS traffic shaping, ensures even, stable traffic transmission on a congested, unstable network. These cards prevent packet loss while reducing congestion and traffic bursts on upstream devices.

The large-buffer cards apply to data center networks and video networks:

• When used on a data center network, these cards ensure fast, stable, and low-latency data forwarding.
• When used on a video network, these cards can prevent voice/image distortion, delay, and asynchronous image and voice presence caused by packet loss and transmission latency, guaranteeing high-quality video conferences.

The following uses a collaborative computing scenario as an example to describe application of these cards in a data center.

Complicated computing tasks, such as search engine computing, oil exploration computing, and meteorological computing, must be carried out by multiple servers simultaneously. In this situation, the servers perform collaborative computing, which results in fast transmission of data flows on a network and traffic bursts when multiple servers send computing data to one server at the same time. Traffic bursts cause congestion on network nodes, as shown in Figure 7-97. Packets are dropped on congested network nodes.

Figure 7-97 Traffic bursts caused by collaborative computing in EoR deployment

As shown in Figure 7-98, all switches from the end of row (EoR) switches to core switches in a data center are equipped with large-buffer cards. These large-buffer cards prevent packet loss caused by traffic bursts in the data center.
