All‑Optical Multi‑Link Aggregation Compliant with Decree No.176: Bandwidth Superposition with Full‑Network Audit & Traceability

As business services on enterprise park networks grow increasingly complex, a single broadband circuit can hardly meet concurrent demands for office work, video conferencing, cloud applications and visitor Wi‑Fi access. Many enterprises therefore subscribe to multiple carrier lines from China Telecom, China Unicom, China Mobile and others, leveraging multi-link aggregation to expand egress bandwidth.

However, adding more lines brings new challenges: How to centrally manage multiple broadband links? Can internet behaviour across different egresses be fully recorded? In case of anomalous access, can administrators trace the specific user and terminal?

Decree No.176, Measures for the Supervision and Inspection of Cyberspace Security by Public Security Organs, will take effect on October 1, 2026. Enterprise network construction must no longer focus merely on internet speed; network security, log recording and traceability for abnormal behaviour are now mandatory.

What enterprises need is not simply “adding more broadband lines”, but expanding bandwidth while implementing network auditing in parallel.

I. Why Audit and Traceability Are Required after Multi‑Link Aggregation

1. Parallel multi-egress lines tend to fragment network behaviour
   After deploying multiple carrier lines, enterprises may route different services out through separate internet links, creating discrete traffic paths.

Under traditional network architectures, operators often only monitor line status and bandwidth capacity, ignoring whether online activities across different links can be logged uniformly. When security incidents occur, administrators have to inspect separate egress devices and scattered logs one by one, greatly increasing traceability difficulty.

1. Bandwidth superposition alone does not equal regulatory compliance
   Multi-link aggregation solves bandwidth capacity issues, while Decree No.176 governs cyberspace security supervision covering network security, data security and information security.

For open environments such as enterprise public Wi‑Fi and visitor networks, multi-line access is insufficient. Enterprises must answer critical questions: who is accessing the network, what terminal is used, when the connection occurs, and what websites or services are visited.

If authentication records are not correlated with network logs, even large volumes of stored logs cannot precisely identify users and terminals during security events.

1. Decentralised log storage leads to inefficient incident investigation
   When routing, authentication, firewall and logging functions run on separate hardware, data is scattered across disconnected systems.

Administrators must cross-reference records across multiple devices to associate accounts, IP addresses, MAC addresses and access behaviour. For small and micro enterprises and industrial parks without dedicated network administrators, this model creates heavy O&M burdens and risks incomplete log fields or insufficient retention periods.

Networks with multi-link aggregation therefore require a unified audit egress, so traffic from all lines enters one consolidated audit system.

II. Bandwidth Expansion and Full‑Network Auditing Implemented Simultaneously

Tailored for multi-service, multi-egress and compliance requirements of enterprise parks, AINOPOL integrates POL all-optical networks, multi-WAN multi-link aggregation and security audit capabilities. Enterprises can expand egress bandwidth while enabling unified authentication, recording and traceability of network behaviour.

1. Unified aggregation of multi-carrier lines to boost overall bandwidth utilisation
   AINOPOL supports unified access to multiple carrier lines from Telecom, Unicom, Mobile and more. Multi-WAN delivers multi-link bandwidth superposition and load balancing.

Traffic for office access, cloud applications, video conferencing and visitor internet access is allocated intelligently according to network policies. Multiple links share business loads to avoid congestion on one line while others remain idle.

Additional broadband connections become a unified pool of network resources rather than isolated egresses. This supports business growth and lays the foundation for centralised security management.

1. Unified audit egress to record behaviour across all links
   The key after multi-link aggregation is channelling traffic from all egresses through a single security gateway for management.

AINOPOL Dream Series secure multi-service gateways combine routing, firewall, authentication and log audit, linking real-name authentication with internet behaviour. Logs capture authenticated accounts, IP, MAC, timestamps and visited URLs for later query and traceability. AINOPOL’s public solution supports local log storage and centralised management via EAAS cloud platform.

Even when enterprises use multi-carrier links for bandwidth aggregation, the unified audit node centrally records network activities and eliminates audit blind spots caused by multiple egress points.

1. Evolve from simple log storage to identity-behaviour correlation
   For enterprise parks, the real value lies not in merely storing network logs, but in the ability to trace back to corresponding identities and terminals once anomalies emerge.

AINOPOL’s solution correlates real-name identity information with IP, MAC, authentication time and access behaviour. When abnormal access appears, administrators can query records by user, terminal, access location and network activity to build a complete traceability chain.

For visitor Wi‑Fi and public office networks, this mechanism resolves the common pain point: detecting suspicious traffic without knowing its source. Network auditing evolves from pure data preservation to actionable behaviour tracking.

1. Integrated communication & security to further protect data transmission
   Under Decree No.176, network construction requires not only logs and auditing, but also continuous network security defence.

AINOPOL’s integrated communication-security concept merges communication and security capabilities. Based on the all-optical network carrying business traffic, encryption transmission and access control strengthen data security.

The enterprise network forms a complete architecture: multi-link aggregation boosts bandwidth, unified audit enables traceability, and integrated communication & security safeguards transmission. Network performance and security are built together instead of deployed separately.

Decree No.176 is more than just adding log retention requirements; it drives enterprise networks from basic connectivity toward manageability, auditability and traceability.

AINOPOL leverages all-optical networks to carry park services, implements multi-carrier line aggregation and bandwidth superposition, and combines security gateways, real-name authentication, log audit, EAAS cloud management and integrated communication-security capabilities. Enterprises expand bandwidth and deploy security auditing in one project.

For enterprises undergoing park network upgrades, rather than purchasing bandwidth equipment and audit systems separately, it is better to plan from the network architecture level to realise higher bandwidth and full-network traceability concurrently.

FAQ

Q: After aggregating multiple commercial broadband lines, will logs be scattered across different devices?
A: No. AINOPOL’s solution converges all broadband lines into the M1 Dream Gateway. Traffic logs from every line are stored on this single appliance. No manual log splicing is required regardless of which egress the user takes to access the internet.

Q: Can the M1 Dream Gateway handle both bandwidth superposition and log auditing at the same time?
A: Yes. The M1 integrates routing, Portal authentication, log audit, IPS intrusion prevention, AV antivirus and WAF web application protection in one hardware unit. Multi-link aggregation and 180-day log retention are native built-in functions, with no separate procurement or configuration required.

Q: What is the difference between network security operation logs and internet behaviour logs?
A: Internet behaviour logs record user-level activities: who accessed what resources at what time. Network security operation logs cover device-level data including NAT sessions, firewall policy hits and link anomalies. Decree No.176 adds new requirements for retaining network security operation logs on top of Decree No.151. The M1 Dream Gateway can enable relevant modules to meet this requirement.
