Introduction

SPN southbound interface standard technical background

As a key technology of 5G bearer network, Sliced Packet Network (SPN) needs to realize standardized interaction between management and control system and equipment. This test method standard is matched with YD/T 4372-2023 technical requirements to build a complete SPN southbound interface technology system.

Core test module architecture

Major test categories	Number of sub-items	Key technical points
Network element and port management	8 items	Board active/standby switching, optical module threshold configuration
Service interface	9 items	L2/L3 VPN model, QoS policy
Synchronization management	4 items	1588v2 time synchronization accuracy

Analysis of typical test scenarios

MTN port mode switching test

The test equipment needs to support dynamic switching of the three port modes of MTN/FlexE/ETH:

Configuration parameters include time slot negotiation mode
Verification switching delay needs to be <50ms
Test topology requires 6-node networking

Standard evolution direction

Compared with the 2019 version, this standard adds:

SR-TP tunnel test (optional)
IPv6 DCN management interface
GPB encoding format support
