Introduction
According to the Notice on Accelerating the Large-Scale Deployment and Application of Internet Protocol Version 6 (IPv6), in order to accelerate the improvement of government application
my country has formulated a series of IPv6 standards to create and expand industry integrated applications, promote the large-scale deployment of IPv6 and standardize innovative application results.
Among them, GB/T 44887 "Technical Requirements for IPv6 Evolution" is a standard formulated to regulate the national IPv6 deployment and is intended to be divided into the following parts.
Part 1.Reference Architecture. The purpose is to define the application scenarios of IPv6 evolution technology in operators and industry fields, as well as the
Deployment in business and industry networks.
Part 2.IP bearer network based on IPv6 segment routing (SRv6). The purpose is to specify the overall IP bearer network based on SRv6.
Architecture, SRv6-based device layer technical requirements, and SRv6-based control layer technical requirements.
Part 3.IPv6 Segment Routing Header (SRH). The purpose is to specify the format of the IPv6 Segment Routing Header (SRH).
and technical requirements for SRH processing at the node.
Part 4.Network programming based on IPv6 segment routing (SRv6). The purpose is to specify the data plane based on SRv6 network programming.
plane, control plane, and management plane.
Part 5.Virtual Private Network (VPN) based on IPv6 Segment Routing (SRv6).
The processing flow and protocol messages of the VPN network include the implementation of Layer 3 services and Layer 2 services.
Part 6.IPv6 Segment Routing (SRv6) Policy. The purpose is to define the technology used to support SRv6 policy.
Development, design and testing of network equipment.
Part 7.Service chain based on IPv6 segment routing (SRv6). The purpose is to specify the data plane technical requirements of service chain based on SRv6.
Requirements and technical requirements for the service chain control plane based on SRv6.
Part 8.Header compression based on IPv6 Segment Routing (SRv6). The purpose is to specify the header compression applicable to supporting SRv6-based packets.
Development, design and testing of network equipment with header compression.
Part 9.Network Fault Protection Based on IPv6 Segment Routing (SRv6). The purpose is to specify the common network fault protection applicable to SRv6 networking.
Network failure scenarios, including SRv6 BE node/link failure, SRv6 Policy intermediate node/end node failure, micro-ring and SRv6
Policy failure scenarios, etc.
Part 10.Enhanced Virtual Private Network (VPN) supporting IP network slicing. The purpose is to specify enhanced virtual private network
(VPN) technical architecture, VPN technical requirements, and SR-based VPN implementation process.
Part 11.IPv6 flow detection technology. The purpose is to specify the data plane flow information applicable to multi-type service carrying scenarios.
Automated quality measurement, as well as development, testing and deployment of IP network equipment flow detection functions.

3 Terms and definitions
The following terms and definitions apply to this document.
3.1
In-situ flow information telemetry
By marking the characteristics of real network business flows, a detection technology that directly detects network performance indicators is implemented.
3.2
postcard-based telemetry
On the packet forwarding path, an in-band flow quality measurement method is used that collects and sends data hop by hop.
3.3
passport mode telemetry
On the packet forwarding path, an in-band flow quality measurement method is used with hop-by-hop collection and tail node uploading.
Note. In passport mode measurement, the flow quality information collected hop by hop is encapsulated in the data message and forwarded with the flow.
3.4
alternate﹘marking (coloring)
By directly marking service messages, quality detection technology that measures indicators such as packet loss and latency can be implemented.
3.5
in-situ operations, administration and maintenance
OAM is achieved by carrying network operation and measurement information in service messages and forwarding them along the service path.
