What is IP header compression?

Users questions: What is IP header compression? Why is turned on, will increase network speed? Opens, you impact on system security?
Experts answer: hit in the right network connection - properties - web-internet protocol - Properties - Advanced - Gouxuan PPP links using IP header compression, you can start (by F A key to see the following Help file) specifies whether to use VanJacobson (VJ) TCP * IP header compression. VJ compression is widely supported by dial-up implementation of the protocol optimization. If you are disabled, it will try to detect the compressed data packets, if found, then the VJ compressed mode Type will automatically start. It will most likely successful connection, and in most cases to provide effective optimal performance. Sometimes, where both ends attempt to test compression, may not activate the compression. If it is determined the remote access server support VJ compression, select the check box to activate the compression, improve performance. By monitoring the connection, "status" dialog "General" tab on the compression of information, you can verify that during compression. If you select this check box, but the remote access server does not support VJ compression, the normal inbound traffic to continue, out of the station communication failure. Because most applications require communication in both directions So stop the conversation is usually
