Replace Government-Enterprise Dedicated Lines with Commercial Broadband: All-Optical Multi-Link Aggregation Cuts Network Expenses by 60% Annually

For SMEs and industrial parks, government-enterprise dedicated lines can partially meet communication requirements, yet long-term rental fees remain high. As business expands, network expenditure keeps rising. Meanwhile, enterprises generally have access to commercial broadband resources from China Telecom, China Unicom, China Mobile and other ISPs. Rational integration of these lines can reduce reliance on costly dedicated lines.

Replacing government-enterprise dedicated lines with commercial broadband is not simply swapping cables. Instead, it re-plans network resources according to business demands. AINOPOL combines POL all-optical networks and multi-link aggregation solutions to unify access and collaborative use of multiple commercial broadband connections, helping enterprises boost bandwidth utilisation and cut overall network costs.

I. High Costs of Government-Enterprise Dedicated Lines: Where Do Enterprises Spend Their Network Budget?

1. High long-term rental fees, mounting pressure amid business growth
   Enterprises requiring HQ-branch interconnection, remote office access or business system access pay for traditional dedicated lines based on line quantity, bandwidth and service levels. As branches multiply and business scales up, more dedicated lines and higher bandwidth are needed.

Some enterprises do not need high-spec dedicated lines 24/7 but still bear fixed monthly rent. Extra charges apply for bandwidth expansion during traffic peaks, making network investment difficult to adjust flexibly.

1. Independent operation of separate lines leads to low bandwidth utilisation
   Some enterprises subscribe to multiple broadband connections, but each line carries fixed services without unified aggregation and traffic scheduling. One line may run under heavy load while others remain idle.

Although enterprises purchase multiple bandwidth subscriptions, they fail to leverage overall resource advantages. Simply adding more lines cannot resolve low bandwidth utilisation.

1. High stability requirements mean dedicated lines cannot be cancelled blindly
   Services such as office work, video conferencing, ERP and remote access have different demands for latency, packet loss and stability. Migrating all services directly to ordinary broadband may cause lags or unstable access for critical business.

Therefore, enterprises need to allocate lines based on business priority. While cutting costs, they should retain essential dedicated line guarantees and improve business continuity through multi-line collaboration.

II. AINOPOL All-Optical Multi-Link Aggregation: Reduce Total Enterprise Network Expenditure

1. Unified access for multi-operator broadband to lower dedicated line reliance
   AINOPOL converged gateways support multi-WAN access, integrating commercial broadband from Telecom, Unicom, Mobile and other operators under unified egress management.

Enterprises can migrate daily office and general internet access to commercial broadband where applicable, while retaining dedicated lines for core services as needed.

Multi-link aggregation reduces dependence on single high-cost dedicated lines, aligning network spending with actual business requirements.

1. Multi-link bandwidth aggregation and load balancing to improve resource utilisation
   After multiple lines are connected, AINOPOL implements multi-link aggregation, load balancing and service traffic splitting to distribute traffic across all lines.

For instance, web browsing and file downloads can be shared across multiple commercial broadband links to avoid concentrating all traffic on a single line. When one line is overloaded, partial traffic can be shifted to other healthy links according to configuration.

This mitigates uneven line utilisation and maximises existing bandwidth resources. It should be noted that multi-link aggregation does not guarantee a single connection can use the sum of bandwidth of all lines. Actual performance depends on line specifications, device capability and business types.

1. Mutual backup among multiple lines to enhance business continuity
   Beyond improving bandwidth utilisation, multi-link aggregation strengthens enterprise network resilience.

AINOPOL’s solution supports multi-line backup. If one line fails, relevant traffic will be switched to other functional lines automatically, minimising disruptions to office work and business access.

Enterprises can design active-standby or multi-coordination line strategies based on business priority, delivering necessary network guarantees for key services while controlling costs.

1. POL all-optical network carries park services to ease construction and expansion pressure
   AINOPOL adopts the POL passive all-optical architecture. With OLT, passive splitters and ONUs, terminals including office PCs, surveillance cameras and access control devices are centrally connected.

The all-optical architecture features large bandwidth, long transmission distance and anti-electromagnetic interference. It also reduces the demand for active aggregation devices and weak-current rooms. For office buildings and industrial parks, the solution can reuse existing optical fibre resources and expand flexibly as business grows, cutting repeated cabling and equipment renovation costs.

1. EAAS cloud management and integrated communication & security, balancing O&M and safety
   With multiple lines deployed, manual status checking, configuration and troubleshooting by administrators will increase operational workload.

AINOPOL leverages EAAS cloud management to centrally manage network devices, line status and policies. It helps operators monitor network conditions in real time and reduce daily maintenance complexity.

Meanwhile, integrated communication and security capabilities are embedded into the all-optical architecture. Synergy between communication and security strengthens safeguards for cross-regional data transmission and business access while boosting line utilisation.

1. Calculate annual savings based on actual business scenarios
   When replacing dedicated lines with commercial broadband, enterprises should evaluate not only monthly rent, but also broadband fees, equipment investment, O&M costs and business SLA requirements.

AINOPOL multi-link aggregation solution helps enterprises audit existing networks, assess which dedicated lines can be replaced, which services are suitable for migration and which lines need to be reserved.

The 60% annual saving target applies to specific project calculations. Actual savings depend on original dedicated line fees, commercial broadband tariffs, equipment and maintenance expenses, and not all enterprises can achieve the same ratio.

For SMEs and industrial parks, network upgrades do not always require purchasing more high-spec dedicated lines. Proper planning of commercial broadband, multi-link aggregation, load balancing and line backup can raise resource utilisation and cut unnecessary dedicated line investment.

AINOPOL takes POL all-optical network as the park communication foundation, combined with multi-WAN access, bandwidth aggregation, EAAS cloud management and integrated communication-security capabilities, delivering holistic planning from internal access and external egress lines to business security.

The core of replacing dedicated lines with commercial broadband is not chasing the lowest price, but assigning suitable services to each line and maximising return on every network investment.

FAQ

Q: Will network stability degrade after replacing dedicated lines with commercial broadband?
A: No. The solution adopts intelligent multi-line mutual backup architecture. Traffic automatically fails over to other lines when one broadband link fails, delivering higher reliability than a single dedicated line. AINOPOL converged routers use intelligent scheduling algorithms to detect line status in real time and ensure uninterrupted services.

Q: How is the 60% network cost saving calculated?
A: Take a branch requiring 100 Mbps bandwidth as an example: a single dedicated line often costs tens of thousands of RMB per month, while two 100 Mbps commercial broadband connections cost roughly one thousand RMB each monthly. Replacing the dedicated line with multiple commercial broadband links can cut annual costs by 60% to 80%.

Q: What is the total bandwidth after aggregating multiple broadband lines?
A: Total throughput depends on the number of broadband links. For example, two 100 Mbps broadband lines can deliver nearly 200 Mbps total throughput. The system supports intelligent aggregation of up to 256 external network lines and can expand flexibly with business growth.
