Introduction to the three-tier network model of Internet products
What is the biggest feature of Internet products? In fact, it is the network effect. Specifically, the Internet itself gives Internet products the most important three characteristics: connection: people connect people, people and things, things and things, and open up an online world in the real world. . Interaction: Simultaneous interaction between large numbers of users, between characters, and between objects. Networking: Users interact and form division of labor and organization, generate social collaboration, and improve production efficiency. Take Taobao as an example, you can use a simplified network diagram to represent the following:
A simplified network blue represents the product, here is Taobao. Other colors represent roles, where red represents the seller; green represents the buyer; yellow represents the Taobao operator. In reality, the seller may ask the model to shoot, ask the professional to take care of the store decoration, and use the advertising system to advertise. When the buyer browses the website, there will be recommended system recommended products. When the buyer places an order, he needs to pay with Alipay. When the payment is successful, the seller will ship the goods, the buyer can query the logistics information, and here is the logistics company and logistics system. This is a more complex network:
A complex network, in addition to Taobao, there are also a lot of cost-effective, Tmall, Tmall supermarkets, panning, flying pigs and other products, which form a more complex network:
The key to understanding a complex network with a more complex network is the communication protocol of the network. First, let's look at the relationship between users and products in this network: From the relationship between users and products: products need to meet the needs of users, and the ability of products to meet user needs is the connection between users and products. From the relationship between users and users: Users should be able to divide and collaborate, and the collaborative relationship between users is the connection between users. From the relationship between products and products: products exist in the form of systems, and the connection between products is the flow of data between systems. The previous network can be abstracted into a three-layer model, as shown in the following figure:
The three-layer network model and the network communication protocol is simplified into a three-layer communication protocol model:
The three-layer communication protocol model: user connection: indicates social cooperation relationship; demand connection: indicates the ability of the product to meet user needs; product connection: indicates data flow between systems.
