Comparison of two versions of WAP protocol stack

We need a protocol stack for a complex network environment. The so-called protocol stack is a collection structure of multiple Ordered protocols. In the communication network, our WAP protocol stack has undergone various changes. First, let's take a look at the comparison between its basic versions.

Considering the network support capabilities, especially the mobile phone support capabilities, in the early stages of mobile data business development, WAPl. the X protocol does not directly use the HTTP/TLS/TCP protocol on the wired Internet, but uses the WSP/WTP/WTLS/WDP protocol and adds the WML language, these protocols are generated based on the fixed network protocol (HTTP/TLS/TCP), but this also causes the inability to directly access the Internet through a mobile phone ｡

With the development of the network, especially the terminal, the difference in transmission performance between the mobile network and the fixed network is reduced. In terms of protocol implementation, WAP2.0 is closer to the mature protocol (TCP and HTTP) of the fixed network ), however, to ensure compatibility with existing mobile phones that only support WAPl.2, WAP2.0 must provide support for the WAPl.2 protocol stack. Therefore, WAP2.0 adopts a dual-protocol stack architecture: including the WAPl.2 protocol stack and WAP2.0 protocol stack ｡

One of the key features of WAP2.0 is to introduce Internet protocols into the WAP environment. It provides wireless network transfer protocols with higher efficiency than WAPl. X on 2G and 3G ｡

In short, to provide IP connection bearing, WAP protocol stack 2.0 with WP-TCP instead of WSP/WTP/WDP in WAP1.2, cannot provide IP connection bearing, the WSP/WTP/WDP cometric stack is still used, so we can say that WAP2.0 has returned to the original HTTP/TCP protocol ｡

Protocol Stack support. based on the WAP protocol stack introduced by X, WAP2.0 has added support and services for the Common Internet protocol stack, including tcp tls and HTTP support, WAP2.0 provides a connection model for a wider range of networks and wireless carriers ｡

Faster: the WAP gateway does not need to convert HTTP/TCP and WSP/WTP/WDP protocols; the mobile phone side does not need to parse WSP/WTP/WDP; this requires Wireless Configuration of HTTP/TCP ｡

Performance Improvement: because a large number of protocol conversions are not performed, the same hardware device supports more concurrent users ｡

Provides end-to-end security. For example, if TLS is used, the WAP gateway does not need to parse HTTP applications, which is passthrough and end-to-end ｡

Rich Content: Because the WAP2.0 protocol adopts a language compatible with the wired Internet, it has gained more extensive support and more applications can be used on the mobile Internet more easily, this is in WAPl. this compatibility also makes WAP2.0 better than WAPl. X has a longer term of use and a stable product form (without frequent upgrades in protocols and Markup languages), allowing mobile users to enjoy the rich content of the wired Internet ｡

It is generally believed that the deciding factor for a technology to succeed in the market is not only the technology itself, but the degree to which it satisfies the needs of users. When the WAP protocol stack first emerged, poor market performance is evidence. Only a large number of content and service providers are further developing a large number of mobile data applications based on WAP2.0. Users can enjoy a satisfactory experience in the use process, users are willing to use the service again, and operators can continue to expand the operating network, enhance the service content, and improve the service level, WAP equipment manufacturers and service providers can also obtain stable returns and good development prospects. Thus, a benign industrial value chain can be formed, this will further promote the continuous development of WAP protocol stacks and related technologies ｡
