Fancy Wang

An ISP backbone is a high-speed network between or within an Internet Service Provider (ISP) that is used to transport large amounts of Internet traffic. The performance and quality of the ISP backbone network directly affect the experience and satisfaction of Internet users. In order to meet the performance and quality requirements of the ISP backbone network, 100G Ethernet, as a high-speed, low-cost, and low-power network technology, has great advantages and potential.

What are the technical requirements of the ISP backbone network for 100G Ethernet?

? Bandwidth requirements: The ISP backbone network requires high-speed network bandwidth to ensure the transmission efficiency and quality of Internet traffic. According to different application scenarios and user requirements, the bandwidth requirements of the ISP backbone network are also different. For example, for high-traffic applications such as video streaming, social media, and online games, it is necessary to support features such as high definition, high frame rate, and high speed; for emerging applications such as cloud computing, Internet of Things, and artificial intelligence, it is necessary to support massive data, Features such as real-time analysis and intelligent optimization. 100G Ethernet can provide up to 100Gbps network bandwidth, which can meet various bandwidth-intensive ISP backbone network scenarios.

? Latency requirements: The ISP backbone network requires a low-latency network to ensure real-time and stable transmission of Internet traffic. According to different application scenarios and user requirements, the delay requirements of the ISP backbone network are also different. For example, for real-time interactive applications such as video conferencing, telemedicine, and autonomous driving, it needs to be controlled within tens of milliseconds; for non-real-time interactive applications such as e-commerce, online education, and financial transactions, it needs to be controlled within hundreds of milliseconds. 100G Ethernet can provide an end-to-end delay of less than 1 microsecond, which can meet various delay-sensitive ISP backbone network scenarios.

? Reliability requirements: The ISP backbone network requires a reliable network to ensure the integrity and security of Internet traffic transmission. Due to the complex and changeable network environment, there may be various interferences and failures, resulting in packet loss, jitter or interruption of Internet traffic. These problems will affect the performance and quality of the ISP backbone network, and even lead to user service interruption or data leakage. 100G Ethernet can provide a variety of mechanisms to improve network reliability, such as forward error correction (FEC), link aggregation (LAG), multipath (MPTCP), etc. These mechanisms can effectively reduce packet loss rate, increase redundancy, balance load and enhance fault tolerance.

? Scalability requirements: The ISP backbone network requires an extended network to ensure the adaptability and optimization of Internet traffic transmission. Due to the rapid growth and diversification of Internet traffic, the ISP backbone network needs to be able to adapt to traffic demands of different scales and types, as well as traffic changes in different regions and time periods. 100G Ethernet can provide various types and specifications of physical layer interfaces and media, such as twisted pair cables, optical fiber cables, electrical backplanes, etc., as well as logical layer protocols of various rates and modes, such as 10G, 25G, 40G, 100G, etc., as well as full-duplex, half-duplex, adaptive, etc. These characteristics can make 100G Ethernet highly scalable and compatible.

What are the application cases of ISP backbone network for 100G Ethernet?

? Interconnection between ISPs: Interconnection between ISPs refers to the connection of different ISPs through high-speed networks to realize the transmission and exchange of Internet traffic. The interconnection between ISPs requires high-bandwidth, low-latency and high-reliability network technologies to support the business needs of large traffic, real-time and stability. 100G Ethernet can provide high-speed, low-latency and reliable network connections for the interconnection between ISPs, and supports multiple protocols and standards, such as BGP, MPLS, IPv6, etc.

? Interconnection within the ISP: The interconnection within the ISP refers to the connection of different network nodes within the same ISP through a high-speed network to realize the transmission and exchange of Internet traffic. The interconnection within the ISP requires high-bandwidth, low-latency, and highly flexible network technologies to support small traffic, real-time, and optimized business requirements. 100G Ethernet can provide high-speed, low-latency and flexible network connections for the interconnection within the ISP, and supports multiple topologies and architectures, such as ring, star, tree, etc.

? Interconnection between ISP and data center: A data center refers to a facility for storing and processing large amounts of data, usually consisting of multiple servers. The interconnection between ISP and data center refers to connecting the ISP backbone network to the data center through a high-speed network to realize data transmission and exchange. The interconnection between ISP and data center requires high-bandwidth, low-latency and high-reliability network technology to support the business requirements of large traffic, real-time and stability. 100G Ethernet can provide high-speed, low-latency and reliable network connections for the interconnection between ISPs and data centers, and support a variety of services and applications, such as cloud computing, Internet of Things, artificial intelligence, etc.

? The interconnection between ISP and Content Distribution Network (CDN): Content Distribution Network (CDN) refers to caching content (such as video, music, pictures, etc.) experience. The interconnection between ISP and CDN refers to connecting the ISP backbone network to the CDN node through a high-speed network to realize the transmission and exchange of content. The interconnection between ISP and CDN requires high-bandwidth, low-latency and high-flexibility network technologies to support small traffic, real-time and optimized business requirements. 100G Ethernet can provide high-speed, low-latency, and flexible network connections for the interconnection between ISPs and CDNs, and support multiple content distribution and recommendation strategies, such as by region, by time period, and by user preferences.

? Interconnection of ISPs with Mobile Operators (MNOs): Mobile Operators (MNOs) are businesses that provide mobile communications services such as voice, SMS, data, etc. The interconnection between ISP and MNO refers to connecting the ISP backbone network to the base station or core network of the MNO through a high-speed network to realize data transmission and exchange. The interconnection between ISPs and MNOs requires high-bandwidth, low-latency, and high-reliability network technologies to support the business needs of large traffic, real-time, and stability. 100G Ethernet can provide high-speed, low-latency and reliable network connections for the interconnection between ISPs and MNOs, and supports multiple communication technologies and standards, such as 4G, 5G, VoLTE, VoWiFi, etc.
