Questions about Segment Routing Technology

How does segment routing technology improve network efficiency?

Segment routing technology improves network efficiency by simplifying the packet forwarding process and reducing the need for complex routing protocols. By using predefined segments in the packet header, routers can quickly determine the path a packet should take through the network, leading to faster and more efficient data transmission.

What are the potential security risks associated with segment routing technology?

While segment routing technology can enhance network security by encrypting sensitive information in packet headers, there may still be vulnerabilities related to key management, encryption algorithms, and potential attacks on the network infrastructure. It is essential for network administrators to implement robust security measures to mitigate these risks.


Original Abstract Submitted

A packet sending method, a network device, and a program product are disclosed, and pertain to the field of segment routing technologies. The method includes: A network device sends a packet which includes a segment routing header SRH and a payload, the SRH includes an encrypted field and an unencrypted field, the encrypted field includes at least an encrypted SID list, and the SID list indicates a transmission path of the packet. A SID list in an SRH of an SRv6 packet transmitted over a POP network is encrypted, thereby protecting SID information from being leaked. In addition, an intermediate node on a packet transmission path only needs to decrypt an encrypted field in the SRH to determine a next hop from the SID list, and does not need to decrypt the payload. This improves forwarding efficiency of the network device and protects secure transmission of the payload.
