Method for enabling non-predetermined testing of network using IP measurement protocol packets
View Patent ↗The practice and need for active network measurement is well established, however, current tools are not well suited to this task, mostly because the protocols which they employ have not been designed for measurement of the modern Internet. The IP Measurement Protocol (IPMP) is based on packet-probes, and is designed to allow routers to participate in measurements by the insertion of path information as the probe passes between a pair of hosts.
1. A method for performing a measurement in a network comprising:
creating an Internet Protocol Measurement Protocol (IPMP) packet by a measurement host;
including, in the IPMP packet, instructions for a recipient of the IPMP packet, said instructions including instructions to the recipient to provide specified information and an instruction to the recipient to insert any additional data desired by the recipient in the IPMP packet when forwarding the IPMP packet; and
including, in the IPMP packet, an identification data element for enabling at least one network device to be identified as a redirect measurement host while redirecting the IPMP packet to the recipient, wherein the at least one network device is comprised in a route between the measurement host and the recipient.
2. The method according to claim 1 , further comprising:
encapsulating the IPMP packet in an Internet Protocol (IP) datagram and a predetermined link layer protocol.
3. The method according to claim 2 , further comprising sending the IPMP packet into the network from the measurement host.
4. The method according to claim 1 , wherein the additional data includes traffic levels.
5. The method according to claim 1 , wherein the additional data includes environmental data, weather data or other information that may impact communications link performance.
6. An apparatus for performing a measurement in a network comprising:
a processor disposed in a measurement host;
a memory coupled to the processor to store computer readable instructions causing the processor to:
create an Internet Protocol Measurement Protocol (IPMP) packet;
include in the IPMP packet instructions for a recipient of the IPMP packet,
said instructions including instructions to a recipient to provide specified information and an instruction to a recipient to insert any additional data desired by the recipient in the IPMP packet when forwarding the IPMP packet; and
include, in the IPMP packet, an identification data element for enabling at least one network device to be identified as a redirect measurement host while redirecting the IPMP packet to the recipient, wherein the at least one network device is comprised in a route between the measurement host and the recipient.
7. The apparatus according to claim 6 , wherein said computer readable instructions further cause said processor to:
encapsulate the IPMP packet in an Internet Protocol (IP) datagram and a predetermined link layer protocol.
8. The apparatus according to claim 7 , wherein said computer readable instructions further cause said processor to send the IPMP packet into the network from the measurement host.
9. The apparatus according to claim 6 , wherein the additional data includes traffic levels.
10. The apparatus according to claim 6 , wherein the additional data includes environmental data, weather data or other information that may impact communications link performance.
11. A computer readable media having encoded thereon computer readable instructions causing a processor to:
create an Internet Protocol Measurement Protocol (IPMP) packet;
include, in the IPMP packet instructions for a recipient of the IPMP packet, said instructions including instructions to the recipient to provide specified information and an instruction to the recipient to insert any additional data desired by the recipient in the IPMP packet when forwarding the IPMP packet; and
include, in the IPMP packet, an identification data element for enabling at least one network device to be identified as a redirect measurement host while redirecting the IPMP packet to the recipient, wherein the at least one network device is comprised in a route between the measurement host and the recipient.
12. The computer readable media according to claim 11 , wherein said computer readable instructions further cause said processor to:
encapsulate the IPMP packet in an Internet Protocol (IP) datagram and a predetermined link layer protocol.
13. The computer readable media according to claim 12 , wherein
said computer readable instructions further cause said processor to send the IPMP packet into the network from the measurement host.
14. The computer readable media according to claim 11 , wherein the additional data includes traffic levels.
15. The computer readable media according to claim 11 , wherein the additional data includes environmental data, weather data or other information that may impact communications link performance.
