With the maturity of ADSL Broadband Access Technology, a variety of new technological applications have already penetrated into thousands of households, resulting in faults. Below, I will share with you several typical ADSL Broadband faults encountered during the maintenance process, hoping to help the ADSL users.
I. Error 678 during dialing
Fault performance: Windows XP SP2 operating system, ADSL virtual dialing user. The error 678 is displayed when you click "Broadband connection. According to
Broadband Access Servers are still commonly used. So I have studied the extended functions of broadband access servers. I will share them with you here, hoping they will be useful to you. The above section briefly introduces the system structure and access functions of the broadband access server.
In fact, the broadband access server function is far from the same. In terms of specific network implementation, the bandwidth access server has changed the
Chat, email sending, download, online video ...... Many of my friends perform these operations at the same time. How can I allocate a limited bandwidth? In this case, we only need to use NetLimiter to allocate bandwidth reasonably.
First install the installation program at http://www.netlimiter.com/download/nl_v130.exe. When the software is installed for the first time, a network configuration window will
Before today, it is always considered that the 2M bandwidth download speed should be 2m/s, but this is not true. The following is an example of the 1M bandwidth to explain the relationship between the bandwidth and download speed that you just understood.Bandwidth is the "highest data rate" that can be passed from one point in a network to another.1M==1MB?

I wrote a typical configuration for a resource download website one afternoon based on my online materials and personal practices. This configuration allows WEB site
Network server bandwidth Mbps, MB/s, MB/s differenceThe meaning of MB/s is megabytes per second, MB/s means megabits per second, the former refers to the number of bytes transmitted per second, the latter refers to the number of bits transmitted per second. The two are completely different.The so-called 10M bandwidth, in fact, refers to 10Mbps (megabits)Computational ba

Network bandwidth resources are limited, some computer high-speed download, online video occupy a lot of bandwidth, resulting in other computers appear "slow Internet, network card" phenomenon. The speed limit function can limit the maximum up and down line speed of the computer, thus ensuring the reasonable utilization of the whole network

The speed limit function can limit the maximum up and down line speed of the computer, thus ensuring the reas
Backplane bandwidth is the maximum amount of data that can be throughput between a switch interface processor or an interface card and an information bus. The higher the bandwidth of a switch's backplane, the stronger the ability to process data, but also the cost of design. But how do we see if the backplane bandwidth of a switch is sufficient? Obviously, the me
How does a router limit the speed of a LAN, how does the LAN allocate network bandwidth, and Control LAN traffic?
The following two methods can be used to limit the network speed of a computer and prevent the network speed of a LAN:1. Methods of limiting others' network speeds, controlling the network speeds of other computers, and limiting lan network traffic through RoutersThe specific method is as follows:1. Enter the correct account passwordMany v
We know that many users reflect that VOLANS routers cannot be superimposed, but they can actually implement the bandwidth superposition function. The specific solution is as follows:1. Shared devices generally allow multiple users to access the Internet at the same time. They can achieve a 4-to-1 M bandwidth overlay function.2. The data flow of some specific applications only follows one line. At this time,
Usb3.1 technology has been released, and the 10 Gbps speed is enough to meet the data and HD video transmission requirements.

However, only bmaxburst of ISO out EP under Alt 2 is 1, while bmaxburst of the other three iso ep is 0, and the mult of all iso ep
Server hosting important one maintenance, to know the cost of the server hosting a year, we need to understand what the hosting server maintenance and which factors are related, these factors are important factors that affect server hosting costs:Server specification Size: Generally have 1u,2u,4u such, the larger the specification, the higher the cost of hosting.Server power consumption: CPU several hard disks several pieces of memory how many models are what these all result in different power

In terms of voice, how does one calculate the bandwidth consumed by codec?By default, after the analog voice is converted to a digital voice, it is cut in 20 ms segments for 20 ms segments, encapsulated with RTP, and then wrapped with UDP header, IP header, finally, the packet header of Layer 2 is sent out.
Suppose we use g.729 encoding and transmit it over Ethernet. Calculate the bandwidth
