Location Awareness to Packet Flows using Network Service Headers |
| 摘要 |
A classifier network device in a service function chain receives a data packet from a first computing device. The classifier network device generates an encapsulated packet for the service function chain by encapsulating the data packet with a network service header. The network service header includes at least one metadata header. The classifier network device determines a location of the first computing device and writes location information corresponding to the location of the first computing device in the metadata header. |

1. A method comprising:
receiving at a classifier network device in a service function chain, a data packet from a first computing device; generating an encapsulated packet for the service function chain by encapsulating the data packet with a network service header, the network service header including at least one metadata header; determining a location of the first computing device; and writing location information in the metadata header, the location information corresponding to the location of the first computing device. |
