Abstract
The invention discloses a method for detecting network routing, which is applicable to the mobile internet. The method includes firstly, establishing an echo-reply type ICMP (internet control messages protocol) packet with TTL (time to live) of 1 by means of a SOCK_DGRAM parameter according to an address of a target terminal by a source terminal; secondly, sending the ICMP packet to the target terminal by the source terminal, and waiting for a timeout reply of TTL of a target machine or a midway router by the source terminal; thirdly, extracting and analyzing the IP (Internet Protocol) address therein by the source terminal after receiving the reply packet; if the packet is sent by the midway router, then recording the IP address of the router, adding 1 to the TTL and returning to the former step; and if the packet is sent by the target terminal or the timeout reply of the TTL reaches the upper limit of the default, completing the whole routing detection. According to the technical scheme, the basic function of traceroute can be implemented on mobile devices, and the collection of data of network connectivity problems in use is facilitated.
Description
Technical field
The present invention relates to mobile internet technical field, relate in particular to the method that a kind of network route detects.
Background technology
At present; In network route testing process; The Traceroute modes that adopt, Traceroute is an order in Unix and the (SuSE) Linux OS originally, can know that through this order information arrives the routing node of object-computer passage in transit from local computer more.
Traceroute sends Internet control message protocol (ICMP) back message using with different life spans (TTL) to object-computer, to be determined to the route of object-computer.Each router on the path all will subtract 1 with its TTL value at least before transmitting this icmp echo message, so TTL is effective jump on count.When the TTL of message value reduced to 0, router was beamed back the ICMP time-out information to source computer.Be first back message using of 1 and in transmission subsequently, the TTL value added 1 at every turn that up to target response or reach maximum TTL value, Traceroute can confirm route through sending TTL.Through ICMP overtime (Time Exceeded) information that the inspection intermediate router is beamed back, can confirm router.
But this mode is not suitable on mobile devices such as mobile phone, using because function is various, and its use SOCK_RAW parameter, needs administrator right to move, and on mobile device, can't realize.
Summary of the invention
The objective of the invention is to propose the method that a kind of network route detects, be applicable to mobile Internet, can on mobile device, realize basic Traceroute function, help to collect the data of the network connectivity issue that runs in the use.
For reaching this purpose, the present invention adopts following technical scheme:
The method that a kind of network route detects is applicable to mobile Internet, may further comprise the steps:
A, source terminal be according to the address of target terminal, uses the SOCK_DGRAM parameter to set up the ICMP bag that a life span is 1 echo acknowledgement type;
B, source terminal send said ICMP bag to target terminal, and source terminal is waited for overtime the replying of life span of router in target machine or the way;
After C, source terminal receive the response packet of router in target terminal or the way; Extract and analyze the IP address in the said response packet, if overtime the replying of life span that router sends in the way, the IP address of then writing down said router; And life span is added 1, return step B; Reply or the overtime upper limit that reaches preset of replying of life span if the life span that target terminal sends is overtime, then accomplish whole route and detect.
Adopted technical scheme of the present invention; Can use SOCK_DGRAM and IPPROTO_ICMP parameter to create socket; Avoided the problem of the necessary use and management person's authority of SOCK_RAW parameter; Thereby can on mobile device, realize basic Traceroute function, help to collect the data of the network connectivity issue that runs in the use.
Description of drawings
Fig. 1 is the flow chart that the network route detects in the specific embodiment of the invention.
Embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and through embodiment.
Fig. 1 is the flow chart that the network route detects in the specific embodiment of the invention.As shown in Figure 1, this flow process that is applicable to that the network route of mobile Internet detects may further comprise the steps:
After step 103, source terminal receive the response packet of router in target terminal or the way, extract and analyze the IP address in the response packet.
The IP address of step 105, record router, and TTL added 1, return step 102.
The SOCK_RAW parameter among original Traceroute that this embodiment has been used the SOCK_DGRAM parameter substitution has been walked around use and management person's authority.Because the SOCK_RAW parameter can let application program that the Ethernet header is had complete control; Therefore can bring comparatively serious safety problem (such as forging MAC Address); So have only the root authority just can be provided with; But the head that SOCK_DGRAM can only the control transmission layer does not have any potential safety hazard, therefore can open to application layer and use.
The above; Be merely the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, anyly is familiar with this technological people in the technical scope that the present invention disclosed; The variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
Claims (1)
1. the method that the network route detects is applicable to mobile Internet, it is characterized in that, may further comprise the steps:
A, source terminal be according to the address of target terminal, uses the SOCK_DGRAM parameter to set up the ICMP bag that a life span is 1 echo acknowledgement type;
B, source terminal send said ICMP bag to target terminal, and source terminal is waited for overtime the replying of life span of router in target machine or the way;
After C, source terminal receive the response packet of router in target terminal or the way; Extract and analyze the IP address in the said response packet, if overtime the replying of life span that router sends in the way, the IP address of then writing down said router; And life span is added 1, return step B; Reply or the overtime upper limit that reaches preset of replying of life span if the life span that target terminal sends is overtime, then accomplish whole route and detect.
