This article describes how to use an external DHCP server to assign IP addresses to your IPsec VPN clients.

We usually have more contact with "hard" routes in our daily lives. 　　The so-called hard routing is a special application of hardware devices, including processors, power supply, embedded software, to provide the configured router function. 　　"Soft" routing is relative to "hard" routing, refers to the use of professional servers, with the free Linux/unix platform or professional Windows platform set up. "Soft" Routing has many advantages: first, should ...

Today, open source firewalls are numerous. 　　This article will cover 10 of the most practical open source firewalls that fit your business needs. 1. Iptables Iptables/netfilter is the most popular command line based on firewalls. It is the safe line of defense for Linux servers. Many system administrators use it to fine-tune the server. The function is to filter packets from the network stack in the kernel, including: listing the contents of the packet filtering rule set, and executing fast because it only checks the header of the packet, and the administrator can ...

For small and medium-sized enterprises, there are many free and open source router and firewall solutions, even as a business choice. 　　Many of these products offer LAN services, such as VPN services, hotspot gateways, and the use of mandatory network portals to share wireless networks. Here, the editors find open source and free router projects that are suitable for businesses that include small businesses, midsize, and even the size of Cisco and Juniper.  Gossip Less, we look at these seven open source and free Linux network operating system. &nb ...

Before the advent of cloud technology, the idea that the network should differentiate between each application has aroused considerable interest in the application of cognitive applications because everyone has a unique need called applied cognitive or applied cognitive networks. Cloud technology is particularly sensitive to application performance issues that are caused by network irregularities, along with potentially hosted applications on the network. The application of cognitive cloud computing requires a more complex application of cognitive methods, and the quality of the user experience will depend more on the availability of the applied energy itself. In most cases, through quality service (QoS) and understanding of network performance ...

The network on the cloud represents a bipolar problem: The Cloud network is one of the basic elements of cloud computing, but it is also one of the factors that make cloud users vulnerable. The degradation of network performance and network instability can greatly affect the use of cloud resources, and therefore, relatively isolated or designed to deal with network outages in the application of running in the cloud will have some advantages. From a different point of view, you can virtualize network resources and use them in cloud computing like other resources. Cloud provider or cloud user will be responsible for different levels of http://www.aliyun.c ...

1th page Cloud Network application cognition: In the end is real or fantasy? 　　"Tenkine Network channel October 31 feature" Before the advent of cloud technology, the idea that the network should treat each application differently has aroused considerable interest in the application of cognitive applications because everyone has a unique need called applied cognitive or applied cognitive networks. Cloud technology is particularly sensitive to application performance issues that are caused by network irregularities, along with potentially hosted applications on the network. Application of cognitive cloud computing requires a more sophisticated application of cognitive methods, the user's ...

Cloud-computing explosions have also brought about the explosion of the term "service", which makes it hard to distinguish between "services". The network as a service seems to be considered superfluous (if it is not a service, what the service provider is selling?) and it is undefined, but we cannot ignore it because it represents the future of the network. The network as a service concept originates from cloud computing and specific support for virtual networks in OpenStack, and the quantum interface describes how to create a network connectivity service to support the connection between cloud computing and storage services. Network is the relationship between service and physical network ...

Today, talk about the more traditional and more real topic-server hosting. Since it is a server hosting, of course, is to choose the right server products for most of the SME users, economic and practical is undoubtedly a fundamental principle of purchase, so the price is significantly higher IBM, Hewlett-Packard and the name of the association we do not think about it; The use of P4+sata system server, although the cost is very low, but the CPU does not have the possibility of dual expansion, disk systems, the average fault-free running time is also low, not conducive to data security, so we ...
