Abstract
The invention provides a method and a system for testing an MTU value in an uplink network model of a router. The method comprises steps of configuring a way to surf the Internet of the router and configuring the to-be-tested MTU value in the router after the to-be-tested router is connected to the assigned server via a wide area network port; setting a test data packet according to the MTU value, wherein the data packet is the same as the MTU value in number, the packaging length of the data packet is selected from 1 to N in order, and N is the MTU value; and testing data packets with package lengths from 1 to N and outputting test results according preset loop test procedures, and determining whether the currently configured MTU value matches the required maximum MTU value according to the test results. The method is advantageous in that test for the MTU value can be automatically, comprehensively and simply performed; and problems in the prior art are effectively solved that test for the MTU value is quite tedious, test workload is heavy and coverage area of the test is not wide enough.
Description
Technical field
The present invention relates to communication technical field, particularly relate to communication router technical field of measurement and test used, be specially the method and system of MTU value under a kind of test router uplink network pattern.
Background technology
Above certain one deck that MTU (Maximum Transmission Unit, MTU) refers to a kind of communication protocol by maximum data packet size (in units of byte).This parameter of MTU usually relevant with communication interface (network interface unit, serial ports etc.).
When connecting less than ISP or can not using other Internet service, and correlation technique support staff advises changing MTU value; As use VPN, can consider when running into performance issue to change MTU; In order to improve some performance of network, employ the application program can optimizing MTU value, and which results in problem that is connective and other aspect of performances.
When a packets of information is sent to the less equipment of MTU value (router), some fritters will be broken down into.In theory, the MTU value on all computers, switch, router and all devices of internet that can have access to should be set to same size.But the MTU value that can not control on internet, and the best MTU value in fact in a local area network (LAN) depends on hardware, software, wave point etc.
The large I revising MTU in one case makes equipment work well, but may cause performance and connectivity problem in other respects; When the equipment with different MTU value intercoms mutually, packets of information will be divided into multiple can pass to the equipment with minimum MTU value; Windows XP Lookup protocol MTU, in other words, it makes MTU for various application combination property optimization.The article of Microsoft explains the reason using the broadband user of Windows XP can not be connected to ISP, once the network equipment has decomposed a packets of information, this packets of information keeps the state of decomposing before reaching a destination always.The process that MTU size is a repetition test is set: decline by maximum 1500, until Resolving probiems.Test is also like this, and decline from 1500 in trial, each MTU value needs to carry out testing authentication.Under router being given tacit consent to various network network access, MTU scope is: DHCP/Static:576 ~ 1500, PPPoE:576 ~ 1492, PPTP:576 ~ 1436, L2TP:576 ~ 1452.
In prior art, generally adopt manual test to the test of MTU, the shortcoming of manual test is loaded down with trivial details, consuming time, can only choose some representative MTU value and test, and reach comprehensively test and will consume a large amount of time and loaded down with trivial details.
Summary of the invention
