Embodiment
Embodiment one
Fig. 1 is the schematic flow sheet of the propagation delay time method of testing of the embodiment of the invention, and as shown in Figure 1, this propagation delay time method of testing comprises:
Step 101, the tester that is arranged on the first website sends packet in the very first time to the router that is arranged on the second website, the destination address of described packet satisfies: when the router of described the second website was transmitted described packet, down hop was described the first website;
Step 102, described tester receives the described packet that the described router that is arranged on the second website is transmitted in the second time;
Step 103 is obtained the propagation delay time of described the first website and described the second website according to the described very first time and described the second time.
Particularly, at the first website tester is set, replaces the router of the first website with this tester, connect the router of the second website.The tester that is arranged on the first website sends the packet that is used for test the first website and the second website propagation delay time to the router that is arranged on the second website, and the record very first time, and this very first time is the time of Packet Generation.This packet can be the packet of arbitrary form, for example both can be the conventional packet that carries out data interaction, also can be the specified format packet that only is used for the test time delay.The destination address that this packet carries meets the following conditions: when the router of the second website was transmitted this packet, down hop was the first website, namely satisfied: after the second website receives this packet, can directly transmit this packet to the first website.
When the router that is arranged on the second website receives the packet that the tester that is arranged on the first website sends, resolve this packet, and the destination address that carries according to this packet is with this package forward to the first website.The tester that is arranged on the first website receives the packet that is used for test the first website and the second website propagation delay time of the router forwarding that is arranged on the second website, and recorded for the second time, this second time is tester receives this packet from the router that is arranged on the second website time.Tester can calculate the propagation delay time of the first website and the second website according to the very first time and the second time.
Because in actual applications, network transfer delay to be measured is usually in a few tens of milliseconds magnitude, and that the router Forwarding Delay only has is tens delicate, so the Forwarding Delay of end-to-end router (namely being arranged on the router of the second website) can be ignored whole delay performance impact.Therefore, propagation delay time is the poor of the second time and the very first time, and this propagation delay time is unidirectional transmission time delay divided by two quotients that obtain.
Propagation delay time method of testing according to above-described embodiment, when the propagation delay time between test the first website and the second website, by sending packet with the tester alternate router to the second website at the first website, so that the second website is behind the packet that receives the transmission of the first website, destination address according to packet directly returns package forward the first website, tester can accurately calculate propagation delay time between the first website and the second website according to time of Packet Generation and reception, thereby has realized efficiently, accurately propagation delay time test.
In addition, since at the first website with the tester alternate router, communicate with the router that is arranged on the second website, can also avoid between the second website, forming route loop at the first website, cause the problem of between two places, constantly transmitting for the packet of test.
Embodiment two

Step 201, the tester that is arranged on the first website sends packet to the router that is arranged on the second website, and the record very first time, i.e. the Packet Generation time;
Wherein, packet carries destination address, and this destination address satisfies: down hop is the first website when the router that is arranged on the second website is transmitted this packet.For example, tester can be according to the routing table of the second station maintenance, the destination address of packet is made as belongs to the address field that down hop is the first website, also can be in static routing of the second website router manual configuration, the down hop of a certain address field is pointed to the first website, and guarantee that this route preferentially comes into force, and tester when sending packet the destination address of packet be set to belong to this address field.
Step 202 is arranged on the second website router and receives and resolve this packet;
Step 203 is arranged on the router of the second website according to the destination address of resolution data bag acquisition, with this package forward to the first website;
Particularly, the router that is arranged on the second website carries out forward process to this packet, according to the routing table of self maintained, determines the forward-path of this packet that is:, and the down hop of this forward-path is the first website.
Step 204, the tester that is arranged on the first website receives the packet of being transmitted by the router that is arranged on the second website, and records for the second time, i.e. the packet time of reception;
Step 205 is arranged on the tester of the first website according to the very first time and the second Time Calculation propagation delay time;
Embodiment three
