Background
Internet Traffic Management on Maritime Vessels in Vietnam
Maritime vessels, including cruise ships and service vessels, often rely on satellite internet connections such as Starlink. While these connections provide essential internet access even in remote ocean locations, they come with high costs, typically calculated based on data usage (GB). To manage these costs effectively, a solution for distributing and controlling internet access onboard is crucial.
Challenges
-
High Cost of Satellite Internet
Satellite internet is expensive, and uncontrolled usage can lead to outrageous costs. -
Limited Bandwidth
The limited speed of satellite internet requires careful management to prioritize critical tasks. -
Need for User Accountability
Without proper controls, users may consume excessive data on non-essential activities, leading to increased costs. -
Configure Bandwidth limitation based on each user’s network plan.
-
Segment the network for each user to prevent interference and protect personal data and privacy.
Solutions and Benefits
The DrayTek Vigor2962 router provides an advanced solution for managing internet traffic on maritime vessels through its user-based management features. This approach allows for precise control over how each user or device accesses the internet, ensuring that data usage aligns with the vessel's operational needs.
1. User Authentication
Every user must log in to access the internet, ensuring that only authorized personnel can use the satellite connection. This is managed through a local user database on the router.
2. Data Quotas
Each user account can be assigned a specific data quota, either on a daily or monthly basis. For example, a user might be allocated 500MB per day or 10GB per month. Once the quota is reached, internet access can be restricted or slowed, preventing overuse.
3. Carry on portal
Users can log in from multiple devices, allowing for flexible access while sharing the same data quota. This is particularly useful for crew members who may need to switch between personal and work devices.
4. Time-Based Access
The router can restrict when users can log in, ensuring that internet usage is aligned with the vessel's operational schedule. For example, access can be limited during peak hours to prioritize critical communications.
5. Firewall and QoS
The firewall on Vigor2962 restricts non-essential services like streaming sites or gambling websites, which are typically high data consumers. Furthermore, Quality of Service (QoS) settings can prioritize bandwidth for mission-critical applications, ensuring smooth operations despite the limited bandwidth of satellite connections.
