Network super speed home hand-conditioned settings
-------------------------------------------------- ------------------------------
When you have a hard work, you can listen to the "cat" crisp, your beautiful mood is a smoky. slow! slow! slow! This is probably a large number of Internet users's most profound experience. In addition to the line of telephone line itself is not enough (we can't change), have you think of there is a problem with the specific operating environment you use, you didn't make special optimizations to it, so it didn't reach your best. State. Because of the various network settings of Win 95, it is not for users dial-up Internet access, but for this network architecture that makes the computer through the Ethernet network. This represents your dial-up speed, perhaps slower than you should have speed. Win98 has been able to automatically determine the dial network used to adjust its setpoint, but its set value does not exert the best transmission performance, so you must also adjust the network settings personally. I. In order to help you better adjust the network settings, please briefly introduce several basic concepts that affect network data transmission speed. 1. MTU (Maximum Transmission Unit) is used to set the size of the data packet exchanged through the line. Under Windows 95, it is a set value according to the 1500-byte standard of the Ethernet network. For dial-up users, most of the ISPs are smaller than 576 byte settings. This approach can reduce the charted probability of damage to the data package due to the microphone of the telephone line. If the host and client computer use two different MTU settings, the connection between the two will slow down because they must coordinate the new transmission rate. When you use dial-up online, your MTU is preferably set to 576. 2. MSS (Packet Data Maximum) Packet Data Maximum value refers to the number of MTU sizes that are used to coordinate interchange data between two network hosts. This value should be 40 more than MTU (in the standard dial-up line, MSS is 536). 3. RWIN (preset reception window) refers to a copy of the data of the transfer data that the computer receives and stored in the hard disk, and the transfer protocol regulates the information from 4, 6, 8 or 10 packets. Operation. If you change the MTU settings under Windows 95, you should also follow the multiple of the MSS settings, reset the RWIN value. If the RWIN value is too large, a group error will result in a packet in the entire buffer being discarded and reissued, and unnecessary losses will be increased. RWIN is too small, the size of the buffer is lower than the group data reached, which will cause the packet to block and reduce the speed. RWIN is preferably an integer multiple of the MSS value, mainly depending on the maximum speed of MODEM, MODEM's maximum speed = ×××× BPS / 9, for example: 56K.V90 modem maximum speed = 115200/9 = 12800bps (no compression In case), the RWin at this time should be 12328 bytes (23 times 536). However, since the quality of the communication lines vary, and the websites that each person goes different, it is recommended that you determine according to the measured effect. 4. TTL (retained time): This network setting refers to the setting of the number of jumper segments when establishing data transmission between different servers, which indicates how many jumps can be passed before failing. The default value of the TTL is 32. For users of the coament, enter the setting area, add TTL to 64, this value is almost for everyone. 5. NDI This is a Cache setting item based on the Token Ring network protocol. If it is not the network using the protocol, you don't have to manage him.
6. PMTU B.H.Detect (PMTUBLACKHOLDETECT) and PMTUDISCOVERY If you are not having problems with newsgroups or email, you don't have to take care of him because it is about communication between the host. II. After understanding the basic concept, you will start to modify now! 1. Modify MODEM port settings, select Start / Control Panel / System / Device Management / Port, find the communication port (for example, COM2) used by Modem, then click "Properties", open the Communication Port (COM2) Properties dialog In the Port Settings option, change the "baud rate" to the maximum value 921600, then click the "Advanced" button to adjust the receive buffer and the transfer buffer to the maximum. 2. Use Notepad to open the C: /Windows/system.ini this system file, add COM2BUFFER = 1024 under [386EN] (assuming 32MB memory, you can change depending on the size of the memory). 3. Add "% C0" in "Attached Settings (X)" in MODEM (Close the frame error mode). Its location is in the start / control panel / modem, click the "Properties" button, select "Connect" option in the Open Properties window, then click the "Advanced" button, fill in the% C0 in the "Additional Setup (X)" box ( It is 0) 0). 4. Next this is the most difficult step, perform C: /Windows/Regedit.exe Open the Registry Editor, modify the registry. 4.1 Looking for / HKEY_LOCAL_MACHINE / ENUM / ROOT / NET, there will be one or more subdirectories, such as "0000", "0001" class, etc., there will be "MSTCP / 0000" in this four-digit directory. String value, remember the four digits behind "MSTCP /". 4.2 Look for hkey_local_machine / enum / network / mstcp / nnnn this directory, where nnnn is the four digits you recorded in the first step (above). In this directory, there will be a word "driver". String value, its content is like NetTrans / NNNN, note the four digits behind "NetTrans /". 4.3 Looking for HKEY_LOCAL_MACHINE / SYSTEM / CURRENTCAL_MACHINE / SYSTEM / CURRENTCAL_MACHINE / SYSTEM / CURRENTCONTROLSET / SYSTEM / CURRENTCONTROLSET / SYSTEM / CURRENTCONTROLSET / SYSTEM / CURRENTCONTROLSET / SYSTEM / CRASS / NETTRAN / NNNN this directory, where nnnn is the four digits you recorded in the previous step, in this nnnn directory, add two string values Name "Maxmtu" and "MaxMSS", then set their values to "576" and "536", respectively. 4.4 Look for HKEY_LOCAL_MACHINE / SYSTEM / CURRENTCAL_MACHINE / SYSTEM / CURRENTCAL_MACHINE / SYSTEM / CURRENTCONTROLSET / SYSTEM / CURRENTCONTROLSET / SERVICES / CURRENTCONTROLSET / SERVICES / CLASS / NETTRANS / NNNN / NDI directory, and "maxInstance" is added then set to "8". 4.5 Look for / hkey_localmachine / system / currentcontrolset / service / vxd / mstcp / directory, new DEFAULTRCVWINDOW, the string content is set to 12328.
