Abstract
The invention provides a trace route testing method, system, device and equipment. The method comprises the steps of: receiving a trace message with a message header carrying a TTL (Time to Live) value as N, wherein N represents the number of spacing equipment between a source mainframe and a target mainframe; copying the message; and adding 1 to the TTL value in a hop-ty-hop option in the original trace message; sending a TTL time-out message to the source main frame when the TTL value in the hop-ty-hop option is not more than the TTL value carried in the message header of the trace message; or else, stopping forwarding the message. At a target node, because a port number cannot be found for the message, a port unreachable message is sent to the source mainframe. Because only one trace message is transmitted in the trace test performed in the invention and used for modifying and completing the trace test according to the copy of the trace message, the number of the message to be transmitted is reduced, and the bandwidth burden is effectively alleviated.

S201: receive Internet Protocol version 6 IPv6 traceroute trace message; Wherein carrying the life span ttl value in the heading of this trace message is N; And the ttl value that also carries in this trace message in the hop-by-hop options is M; N is the amount of equipment of being separated by between source host and the destination host, and M is not less than 1 integer.
S202: whether the destination address of judging this trace message is local address, when confirming the non-local address of destination address of this trace message, carries out step S203, otherwise, carry out step S207.
In addition, when source host sent the trace message, the ttl value in the hop-by-hop options of carrying in this message was set to 1 in the present invention.Certainly the initial value of TTL is set to other integer values and also is fine in the hop-by-hop options, judges whether that according to the ttl value in this hop-by-hop options continuing to send this trace message gets final product as long as how follow-up intermediate router and destination host are known.
S203: copy this trace message, and the ttl value in the hop-by-hop options in the original trace message is added 1 back forwarding.
In the present invention in order to realize sending a trace message; Each equipment that bar is jumped on the link all carries out the trace test; When each equipment (intermediate router or destination host) receives this trace message; Copy this trace message, judge whether to return the TTL timeout packet to source host to the trace message of this copy.And transmit processing for original trace message.
S204: judge that whether the ttl value add in this hop-by-hop options after 1 carries ttl value in the heading greater than the trace message, when judged result when being, carry out step S206, otherwise, carry out step S205.
Because this trace message whenever is forwarded once, the ttl value in its hop-by-hop options of carrying is upgraded, according to the ttl value in the hop-by-hop options of carrying in the trace message after upgrading, judge to source host and send the TTL timeout packet.
S205: the ttl value in this trace message that will copy is revised as 1 and when transmitting, the ttl value in this trace message of copy is subtracted 1 after, become 0 after its ttl value subtracts 1, send the TTL timeout packet according to the agreement regulation to source host.
S206: stop forwarding this message.
S207: to the unreachable message of source host transmit port.
In the present invention for middle router and destination host are tested; Source host is after sending the trace message; Record sends the time point of this trace message; According to said delivery time and receive moment of each error message, judge whether the equipment between source host and the destination host breaks down.Wherein this error message comprises TTL timeout packet and the unreachable message of port.
Concrete, in the present invention according to said delivery time and receive moment of each error message, judge whether the equipment between source host and the destination host breaks down, comprising:
According to each jumps t average time that sends the TTL timeout packet between said delivery time and this source host and the destination host, confirm to receive the time that each jumps the TTL timeout packet;
According to each times prior of jumping the TTL timeout packet, whether receive the TTL timeout packet that this jumping is returned, judge whether this jumping can reach.
In the present invention in order to save bandwidth, the trace message that source host sends, for having utilized Internet Protocol version 6 (IPv6) hop-by-hop options heading, this message at each equipment place of its process, all detects this message in the process of transmission.In this IPv6 basic agreement stack; The form of this hop-by-hop options heading is as shown in Figure 3; One by one in the option heading preceding 8 be the information of next heading, identified immediately following type at the next heading of hop-by-hop options heading back, extension header length is unit with 88 hytes; The length that does not comprise the hop-by-hop options heading of preceding 88 hytes is option afterwards.

After the first hop router R1 receives this trace message; Adopt the IPv6 agreement that this message is resolved; According to the destination address of this trace message, judgement need be transmitted processing to this message, and owing to carry hop-by-hop options in this message; Confirm that this message is the trace message, need carry out trace and handle.
The first hop router R1 is a trace message copy earlier, and the value of the TTL in the hop-by-hop options in the original trace message is added 1, and the ttl value in this hop-by-hop options becomes 2 at this moment.Judge that 2 are not more than 4; Ttl value in the heading in the trace message of copy is revised as 1; Carrying out the process that message is transmitted afterwards, is 0 after in the time of forwarding the ttl value in the heading in this trace message being subtracted 1, and then this moment, the first hop router R1 sent the TTL timeout packet.
After receiving this trace message for the second hop router R2; Adopt the IPv6 agreement that this message is resolved, judgement need be transmitted processing to this message, and owing to carry hop-by-hop options in this message; Confirm that this message is the trace message, need carry out trace and handle.
The second hop router R2 is a trace message copy earlier, and the value of the TTL in the hop-by-hop options in the original trace message is added 1, and the ttl value in this hop-by-hop options becomes 3 at this moment.Judge that 3 are not more than 4; Ttl value in the heading in the trace message of copy is revised as 1; Carrying out the process that message is transmitted afterwards, is 0 after in the time of forwarding the ttl value in the heading in this trace message being subtracted 1, and then this moment, the second hop router R2 sent the TTL timeout packet.
To the 3rd hop router R3, it continues above-mentioned and first hop router and the second hop router identical operations, the trace message is sent to destination host after.Destination host is resolved this message, and judgement need be carried out this locality processing to this message, because can not find port numbers, to the unreachable message of source host transmit port.
Because each hop router all can send the TTL timeout packet to source host; Therefore in its hop-by-hop options, all include ttl value in each TTL timeout packet that source host receives; And comprise IPv6 address, source; Therefore source host can be with the ttl value in the TTL timeout packet that receives, and the time of reception that reaches IPv6 address, source and each TTL timeout packet is noted.
Concrete; To the two-way time of first hop router is to receive that first hop router returns the time and the time difference that sends the trace message of TTL timeout packet; Be designated as T1, be T2 the two-way time of corresponding second hop router, and it equals time and the time difference that sends the trace message that second hop router returns the TTL timeout packet; And the like, can confirm two-way time of each jumping.
And, in source host, be provided with the time-out time t of trace message, for first hop router corresponding overtime t two-way time, second jump corresponding overtime be 2t, it is Nt that corresponding N jumps the overtime of correspondence.When TTL timeout packet that the router that in this time-out time, does not receive corresponding jumping returns, confirm that then this hop router is unreachable.If source host has received the unreachable message of port that the destination address destination host returns, then the Trace test process finishes.If source host is never received the unreachable message of port that the destination host of destination address returns,, confirm that then the equipment between source host and the destination host breaks down up to reaching the max-timeout time (time-out time * maximum probe ttl value).
