　　While the Olympic Games are in full swing in Paris, France, the U.S. presidential election has also become a hot topic of global attention. Since Trump got a higher approval rating than Biden in the assassination, there has been a “dark horse” on the road to the US presidential election. Harris, known as the “Black widow,” has become a strong opponent of Trump and has gained very high support rates in a very short period of time. European and American media said that Harris is expected to become the first female president of the United States.Hope for the future business bodyguard It can achieve rapid and stable development and serve social development and people’s needs well. http://huanyubodyguard.com/

　　The reason why Harris received a high vote support rate in the short term is that Harris openly supported women’s rights, supported illegal immigrant groups, and expressed love for women and children in the speech process. During Harris’ speech in the United States, his mental state was very full, and there were bodyguards around Harris for personal security protection.

　　The reason why Harris can become a strong opponent against Trump in a short period of time, and she is of Indian descent and black origin has a considerable relationship, plus Harris is a woman, easy to get the support of feminists around the world. In addition, what Harris supports is not the same as what Trump supports, so in the short term, Harris has shown a good advantage in the US presidential election. Harris, like some rich women in Shenzhen, China, is calm and confident, has a strong personality charm, and has a strong sense of safety and self-protection. The female rich in Shenzhen, China, will hire bodyguards from the Huanyu Brothers bodyguard company in Shenzhen, China, and Harris will bring elite bodyguards to the United States to give speeches and escort personal safety.

　　As for whether Harris can defeat Trump to become a female president in the history of the United States, it also depends on Harris’s late vote support rate and the public opinion of the American people, but Harris has now become a fierce enemy on Trump’s campaign road.

　　When we buy optical modules, we often see descriptions such as “compliant with a certain IEEE Ethernet standard” and “compatible with InfiniBand xDR protocol” in the introduction. So, as common communication network standards, InfiniBand (IB) and Ethernet (Ethernet), what are the specific differences?Only by working together can we turn 800g qsfp-dd The value of the play out, the development of the supply market needs. https://www.3coptics.com/

　　Design Goal

　　InfiniBand (literally “infinite bandwidth” technology, abbreviated as IB) is a dedicated protocol originally designed for connections between servers, storage and network devices to meet the needs of data centers. It uses high-speed differential signal technology and multi-channel parallel transmission mechanism, with the main goal of providing high performance, low latency and high reliability.

　　Ethernet is a general-purpose protocol that is widely used for local area network (LAN) and wide area network (WAN) communications. It uses the carrier sense multiple access/collision detection (CSMA/CD) mechanism to avoid collisions, and its main goals are simplicity, flexibility, and scalability.

　　Transmission rate and latency

　　InfiniBand supports multiple transmission modes, including SDR (single-channel reception), DDR (dual-channel reception), QDR (quad-channel reception), FDR (differential reception), EDR (extended differential reception), HDR (high-density reception), and NDR (narrowband differential reception). These transmission modes have different characteristics and advantages and are suitable for different application scenarios.

　　Ethernet also supports multiple transmission rates, such as 10Mbps, 100Mbps, 1Gbps, 10Gbps, 25Gbps, 100Gbps, 200Gbps, 400Gbps, etc. However, the delay of Ethernet mainly depends on the performance of network devices and network traffic.

　　Since InfiniBand uses faster transmission rates and dedicated hardware, it has a clear advantage in terms of latency. In contrast, Ethernet has a higher latency, mainly due to the complexity of the protocol stack and some additional processing steps.

　　Reliability and Scalability

　　InfiniBand has the characteristics of high reliability and low power consumption, which can meet the performance and reliability requirements of modern data centers. It uses high-speed differential signal technology and multi-channel parallel transmission mechanism to achieve extremely high data transmission rates and extremely low latency. In addition, InfiniBand also has the characteristics of high reliability and low power consumption, which can meet the performance and reliability requirements of modern data centers.

　　Ethernet is a general-purpose protocol that is widely used for local area network (LAN) and wide area network (WAN) communications. It uses the carrier sense multiple access/collision detection (CSMA/CD) mechanism to avoid collisions, and its main goals are simplicity, flexibility, and scalability.

　　Cost and Maintenance

　　InfiniBand is a dedicated protocol that requires the use of specialized hardware and software. Therefore, the cost of InfiniBand is relatively high. However, since InfiniBand is designed specifically for data center environments, it has lower environmental requirements and lower maintenance costs.

　　Ethernet is a universal protocol that can use standard Ethernet switches and network cards. Therefore, the cost of Ethernet is relatively low. However, due to the complexity of Ethernet design and configuration, the maintenance cost is high.

　　Applicable fields

　　Based on the characteristics of the two protocols, InfiniBand is mainly used in the field of high-performance computing, such as supercomputers, data centers, and scientific research institutions. Its advantages lie in high-speed transmission, low latency, and scalability.

　　Ethernet is widely used in enterprise networks, Internet access, home networks and other fields. Its main advantages are low cost, standardization and wide support.

　　In conclusion, InfiniBand and Ethernet are two different data center network communication technologies, and they differ in design goals, transmission rate and latency, reliability and scalability, cost and maintenance, and applicable fields. Based on the needs and limitations of actual application scenarios, you can choose a suitable protocol to meet specific requirements.

　　With the development of technology and changes in the market, these two technologies are also constantly evolving and competing. In order to adapt to the growing needs of data centers, both Infiniband and Ethernet are undergoing continuous technological innovation and upgrading. For example, Ethernet continues to improve network performance and reliability by introducing new technologies such as non-blocking network design and switch topology; while Infiniband is also constantly optimizing performance and reducing costs to expand its application scope.

Here¨s a guide to help you find the best options.Gold and silver are not as good as clear waters and green mountains. This is an environmental protection slogan put forward in recent years. When you order milk tea at home or in the office, you will get a packaging bag. A small packaging bag may not have any impact on the environment, but when people gather together, so many people order milk tea every day. Over time, the pollution caused by this plastic milk tea bag to the environment is still very serious, because ordinary Plastic can exist in nature for hundreds of years. If it is burned, it will also produce dioxins and other pollutants, causing serious damage to the environment.The industry believes that, recycle trash bags The development of our company marks the rapid and steady progress of the whole industry. https://biodegradable-gd.com

　　For the sake of environmental protection, the country has strictly restricted the production and sale of disposable plastic products such as plastic shopping bags since January 1, 2021, referred to as the “Plastic Ban”. As a result, supermarkets, restaurants, milk tea shops and other places have replaced plastic shopping bags with biodegradable bags to meet environmental protection requirements.

　　Among the solutions to replace plastic products, biodegradable materials have attracted everyone’s attention. Because the raw material of biodegradable milk tea bags, polylactic acid PLA, comes from plants such as corn and potatoes, and the source of raw materials is very environmentally friendly and natural. After use, biodegradable milk tea bags can be degraded into carbon dioxide, water and other substances in the landfill in about 180 days. They will not become “white garbage” like plastic bags and pollute the environment. With the implementation of the plastic ban, many milk tea shops have assumed the responsibility of environmental protection and have replaced plastic bags with compostable milk tea bags.

　　Therefore, when purchasing biodegradable products, you must carefully identify them. Here are some simple identification tips:

　　1. Choose products from large manufacturers, which are more reliable and reduce the risk of buying by mistake.

　　2. Read the ingredient description. When purchasing biodegradable milk tea bags, we can ask the manufacturer about the ingredients of the bags, which are generally polylactic acid (PLA), polyadipate (PBAT), and starch. Others such as PE+starch are pseudo-degradable. Relevant documents stipulate that degradable materials cannot contain plastic components such as PE, PP, PVC, and PET. Products such as PE+starch and PE+photooxidant are pseudo-degradable and need attention.

　　To find a reliable compostable milk tea bag, focus on verifying the materials, assessing environmental impact, evaluating quality, and considering brand reputation. By doing thorough research and possibly testing samples, you can ensure you choose a product that meets your needs while contributing to environmental sustainability.We are both victims and beneficiaries of environmental protection. For environmental protection, we can start with small things around us, starting with using one less plastic shopping bag and one less plastic straw.
