network interface device uses 50U gold-plated thickness to improve the stability of the network connection.
The network of the Internet cafe is upgraded. The backbone switch is the heavy weight of the header. When selecting a backbone switch, four factors must be taken into account: performance, reliability, scalability, and QoS.
Here I recommend SpeedNetworks SP 2400GM/NT to Internet cafe owners. There are also Gigabit networking solutions for this
As a leader in the routing industry, there is a lot of market demand. Here we mainly analyze the Cisco router configuration issues. Cisco SDM is based on Cisco IOS? An intuitive Web device management tool developed by Software routers. It simplifies Cisco router configurations through smart wizard, so that customers and Cisco partners do not need to understand the CLI) can we quickly and easily deploy, configure, and monitor Cisco Systems? The company's router. Many Cisco router configurations a
More than 40 countries around the world have carried out 100 PLC connected lab projects to ensure the feasibility of PLC Technology and commercialization. In order to expand the Power Line Communication Market, current research hotspots focus on the integration of power line access and IPv6.
The feasibility of IPv6 technology and PLC Integration
In recent years, several important fields of communication technology have developed considerably, including IPv6,
Architecture router, and the vro Based on the cluster system.
Router Composition
A vro has four elements: the input port, the output port, the switch, and the route processor.
The input port is the entrance of the physical link and input package. A port is usually provided by a line card. A line card generally supports 4, 8, or 16 ports. An input port has many functions. The first function is to encapsulate and deencapsulate the data link layer. The second function is to find the destination ad
a limited range, which may be a device of the same brand, a man or a carrier. For WAN users, in recent years, with the increase in basic network investment by operators, the basic network traffic requirements have been basically solved, and the pipeline is already wide enough, quasi-intelligent networks based on a city and a region cannot meet their needs.
Therefore, the carrier's WAN network will only be a network with a lack of overall brain for a long time in the future and will not meet the
, packet encapsulation at the IPSec virtual tunnel interface eliminates the need for additional encapsulation of GRE headers or L2T for incoming tunnel traffic compared to IPSec over GRE or IPSec over L2TP tunnel encapsulation The P-header reduces the level of packet encapsulation and saves bandwidth.More flexibility in business applications: IPSec virtual Tunnel interface in the implementation of the clear areas of the "pre-encryption" and "post-encryption" two phases, users can flexibly choose
The user said that several websites may disappear after using the user reconstruction function. After checking one of the servers, the staff found the reasons as follows:
A large number of sites on this server use the bandwidth restriction function (that is, to limit the maximum bandwidth of a Website per second). However, QoS service is not installed in the NIC, as a result, IIS considers this to be a wrong website and will lose it. The solution t
by IP technology, while the ATM technology will exit the historical stage. In fact, as long as you carefully analyze and study the characteristics of the IP technology and ATM technology, it is not difficult to find this view is one-sided. For the construction of network telecommunication networks or computer networks, its development will not change with the emergence of new technologies), but it can only evolve gradually. The existing telecommunication network has formed a huge amount of reso
complementary.SDH-TDM is a mature and widely used technology, and is the most basic infrastructure of the existing network. To consider the economics and reliability of the broadband network, it is necessary to establish it on the existing SDH network. IP is a type of connectionless. Routing Technology. In this aspect, IP applications on the Internet show their advantages in price and performance.ATM is a connection-oriented technology that uses cell Packet Exchange. The bandwidth statistics re
the router inconspicuous.
Of course, the wireless router requires an AC outlet and a connection to your cable or DSL data source. If the building's DSL or cable modem lines are in an inconvenient position, please don't panic, you can use directional antennas (we'll mention the next serial article), or extend your DSL and cable lines.
If you choose the latter, you will find that the wall-broken wiring is a laborious and costly project to keep your router in the right place and can cause damage
not change hardware frequently can set the device type above the bus device to None (none) in the system properties.
3, turn off the effects of the system properties, this is a simple and effective way to speed up. Click start → control Panel → system → advanced → performance → settings → in the visual effect, set to adjust for best performance → OK. So the desktop will be very similar to Win2000, I still like XP blue window, so in the "Use visual style on Windows and buttons" tick, so as to s
according to the common port. Security equipment filtering function has URL filtering, MAC address filtering, content filtering, anti-network attacks, ignoring WAN ping, etc., these functions can only play a general preventive role, can be said to be against the gentleman, the villain is still difficult to prevent.
In addition to the general security features, the router that adapts to Internet cafes should also have QoS features, line backup functi
deletion of scalable VPN users is only a logical operation, without the need for specialized physical devices and connections.Easy to manage the enterprise can outsource the VPN solution to the ISP, and focus on the enterprise's own business, rather than on the network.The secure access VPN for mobile users can be used for global Internet access of growing mobile users worldwide.Quality of Service (QoS) guarantees that VPNs can provide a certain qual
The quality of Service (QoS) policy in Windows Server 2008 and Windows Vista allows network administrators to prioritize traffic between specific clients and servers, or between application servers. Priority selection settings can determine the specific application name, specific resources and destination IP address, as well as specific resources and target TCP or UDP port. QoS policy settings are configure
undoubtedly a good solution in Multi-Service routers. In addition, all users put QoS first in terms of support for PoE, QoS, MPLS and IPv6. Indeed, the core of multiple businesses is to differentiate the types of businesses, and then provide corresponding policies based on different businesses to allocate different service quality. As said Wu Jianxin, Cisco ISR product manager, "
With the rapid development of IP networks and applications, the next-generation network (NGN) based on the IP bearer network and Softswitch technology has been widely considered as the most suitable technology for realizing the three-in-one network. As NGN adopts a separate architecture of Call Control and media bearer, it enables operators to maximize their network potential and attract users by providing various new telecom services, and effectively reduce operating costs, thus greatly improvi
mode not only greatly improves the transparency of user access operations, but also reduces the configuration process of user terminals, it can also serve as a business portal to provide space for the next service expansion. For operators, this is indeed an ideal business operation mode and has become the future direction of business development.

Application VoIP service quality (QoS) has four key steps. If you do not follow these four steps, your VoIP implementation will not realize its full potential. In addition to enabling the vro function, QoS has many things to do. Therefore, it takes some time for you to plan and design the correct QoS for your speech environment. The following are the four key ste
specifications are added for the LMDS/MMDS market. These extensions will be included in a new standard or an extension of the existing DOCSIS standard), which is currently being studied by the IEEE 16th Committee. At present, the market has launched a DOCSIS-based wireless access system. However, how to ensure real-time business and reliable application in the wireless environment requires further lab verification, which is also a further improvement of this standard.
Since the DOCSIS specifica
