We are introducing a new feature for VSAT-connected vessels called Hunking, designed to help IT teams manage the growing size of Microsoft Windows updates within strict monthly bandwidth limits.
Windows update packages have increased significantly in size. Updates that were typically around 1.0 GB last year are now commonly 3 GB or more, with this month’s release reaching 4.5 GB. For vessels operating on VSAT, these update sizes can create a substantial bandwidth burden.
Even with A9X Windows Update’s standard optimized delivery, large Microsoft updates continue to present a challenge for bandwidth-constrained vessels. Without A9X, a 4.5 GB update deployed across 10 PCs could consume more than 45 GB of total bandwidth. On VSAT, that level of usage is not feasible, and even on a modest Starlink package shared between business and crew traffic, allocating 45 GB to Windows updates is difficult to justify.
To address this, Hunking enables administrators to define a fixed monthly data allowance for Windows updates. A9X then delivers the required update in controlled parts over multiple months, rather than attempting to download the full package at once.
For example, if the monthly update allowance is set to 2 GB, a 4.5 GB Windows update would be downloaded in three separate hunks over a three-month period.
Unlike standard Windows Update behaviour, A9X does not discard partial progress. The system locks onto the selected update, retains the downloaded portion, and continues delivery until the update is fully completed and installed. This avoids repeated partial downloads and reduces wasted bandwidth.
Key Benefits
- Predictable monthly bandwidth consumption for Windows updates
- Improved suitability for VSAT-connected vessels
- No loss of partially downloaded update data
- Assurance that updates are completed and installed over time
Hunking has been developed specifically for vessels where bandwidth is limited, costly, and operationally critical.
