SummaryWap push has the advantages of active and timely information transmission and the ability to receive information anytime and anywhere. Therefore, it has good application prospects. This article briefly introduces the wap push system framework, PUSH protocol and PUSH method, and focuses on the implementation of wap push through sms gateway. KeywordsWireless Application Protocol, wap push, SMS gateway,

If you want to enter the official website, you should first break through the gateway (GetWay). This is easy to understand, because an intranet must always access the internet through the gateway. As for how to break through the gateway, this is no different from accessing a server that is not a gateway. After breaking

With the rapid development of network technology and information appliances, more and more families require the establishment of a home network. The home gateway is the core of the entire home network. It implements Internet access, remote control, and the function of connecting to a heterogeneous subnet in the home. The home gateway based on the PC solution is not only costly, but also requires that the co

Address: Use 21 bits to identify the network number, 8 bits to identify the host number, the front three bits are "110". The first paragraph of the Class C address has a value between 192~223, the first, second, and third paragraphs together to represent the network number. The last segment identifies the host number on the network. Class C addresses are suitable for small networks such as campus networks, and each class C network can have up to 254 hosts.From the above introduction we know tha

In a broad sense "gateway" refers to a network connected to another network "interface", such as an enterprise's intranet and the external Internet link, you need a gateway to manage and control. It is a kind of complex network connection device, which can support the conversion between different protocols, and realize the interconnection between different protocol networks. The so-called wireless

Wedge Networks, a world-renowned high-performance Web 2.0 security solution leader and high-end Web security device provider, announced that, beSecure Web security gateway participated in the horizontal comparison test of the "Performance Analysis and deployment of security gateway devices in content security applications in the Chinese Web application environment" research project of the Institute of Publi

After this period of thinking, practice, frustration, rethinking, and then practice, the API Gateway scheme is summed up. Overall goal Mainly in order to solve the SOA service framework to provide external API related issues, mainly related to the following aspects: Unified authentication of the flow of anti-attack system split API horizontal expansion, high availability, load all horizontal service automatic scaling ... To solve a series of problems

To get a thorough understanding of BGP, we'll start by answering the seemingly simple question of why BGP is needed, that is, how BGP is generated, and what it solves. With these questions, we will briefly review the trajectory of a routing protocol development.The essence of the first route is to describe the expression of a network structure, and the routing table is actually a collection of results. In the early Arpanet network era, the network size is limited, the number of routes is not sma

two digits can be arbitrarily varied within the 0~255 range, providing 2,552 IP addresses. However, the actual number of IP addresses available is 2552-2, or 65,023.The subnet mask setting for the IP address is not arbitrary. If the subnet mask is set too large, that is, the subnet range is enlarged, then, according to the subnet path rule, it is likely to be sent to the local machine is not in the same subnet of the destination machine data, because of the wrong judgment and think that the des

can get the required information from data dictionary of the Heterogeneous data source d) Convert data types between heterogeneous data sources and Oracle databases e) make up for the non-existent function method in the heterogeneous data source, so that it becomes a number of production-required statements to obtain the corresponding results. HS components have many common encodings and are configured to work together with many different heterogeneous data sources. Each

With the development of IPTV business in China, the bearer network has shifted from the original single service to the multi-service bearer. Similarly, for broadband users, previously only PC Internet terminal, the opening of IPTV business, business Terminal added a set-top box. Other business terminals, such as IP telephony, may also be added in the future. The use of multi-service terminals has directly promoted the application of home gateways in the home. What is a home

Shared guard version 2.0 has added many features. The most important one is that it can provide automatic host switch. In order to ensure the implementation of the host switching function, the configuration is much more complicated than Version 1.0, especially when users use the fixed IP Mode of a single Nic, the concept of the virtual network card and the virtual gateway is not very clear, resulting in configuration errors and cannot access the Inter

Recently, some friends have reported that they are not familiar with the configuration of wireless gateways, so I will explain in detail some questions about wireless gateways, including the selection of wireless gateways, wireless gateway settings and explanations of some related terms. In a broad sense, a "Gateway" refers to the "interface" connecting a network to another network. For example, if an enter

Gateways (Gateway) are also known as inter-network connectors, protocol converters. The gateway realizes network interconnection above the network layer, is the most complex network interconnection device, only for two high-level protocol different network interconnection. Gateways can be used for both WAN interconnection and LAN interconnection. A gateway is a c
