What Is DBA

With the vision of "building a new generation of national cabling that combines optical and copper, integrates networks, and smart cabling", adhering to the mission of "making signal transmission faster, safer, and more energy-efficient", we vigorously promote the research and development of optical communication equipment and are committed to providing advanced, comprehensive, and high-end all optical network solutions for information communication in various industries such as enterprises, healthcare, education, and transportation. Recently, Yuhong Communication has introduced "DBA technology".
Q: Some people say that an all optical network is a point to multipoint structure. When using a 1:16 or higher splitting ratio, there will be issues of "bandwidth sharing" and "insufficient single point bandwidth". It is not as good as a 1:1 symmetric high bandwidth network experience on an Ethernet all optical network. Is that true?
A: Of course not. The surface of the Ethereum full optical network is 1:1 symmetrical up and down, but in reality there is also an invisible spectral ratio. Taking the weak current room of a building as an example, the all optical convergence switch has a 40GE uplink, with 288 10GE ports on the user side. There is a convergence ratio of 40GE/2880GE, which is 1/72, and the congestion point is the uplink port. At the same time, due to the lack of a dynamic bandwidth mechanism to ensure bandwidth and maximum bandwidth in all optical aggregation switches, 2880GE's uplink data undergoes indiscriminate packet loss when the uplink port 40GE is congested, which has a very negative impact on the business experience and may lead to poor experience for small bandwidth office services, as small bandwidth traffic is crowded out by other users' large bandwidth traffic. The network congestion of the all optical network is controllable and has the function of fine bandwidth management DBA, which can not only ensure user business but also improve the bandwidth utilization of ports. The use of a 1:16 splitting ratio is also far superior to the invisible 1:72 splitting ratio of all optical convergence switches.
