Milestone #2
- Experiment takes time due to environmental factors and more complicated experiment process than initially planned
- Additional experiments and technical analysis were conducted to satisfy the requirements.
- The roles of modules and team members have been rebalanced in the design process.
- Team 1 changed the process to register individual tasks as issues, share statuses, and update progress using GITHUB Kanban
- Project : https://github.com/users/changjurhee/projects/3/views/1
- Issues : https://github.com/changjurhee/AONE/issues
- (Availablity ASR) Apply jitter buffer for network jitter (for audio/video)
- (Availablity ASR) Apply packet duplication for netwrok packet drop (for audio)
- (Performance ASR) Apply dynamic video quality change rule for network condition changes
- (Technical RISK) Use STAR TOPOLOGY that minimizes connection links to ensure performance and availability QA in low bandwidth
- (Technical RISK) Use the proven GStreamer open source for development efficiency, stability, secured data transfer w/ plugin module.
| N | Status | Experiments | Risks / QA tracability / Issues |
|---|---|---|---|
| 1 | Concluded | Network bandwidth measurement in operating environment | (Technical Risk) Find Video transfer throughput to meet Performance ASR within STAR topology. |
| 2 | Concluded | Find the correlation between network bandwidth and video quality. | (Technical Risk) Find optmal video qualitity to gurantee communiation availability (Performance QA) To make proper video bandwidth resize logics within network & participant condition |
| 3 | Concluded | Verify that receiver can improve network jitter problems using the jitter buffer. | (Technical Risk ) How to check and recover network jitter (Availability QA) System maintain call quality under amount of increated network jitter |
| 4 | Concluded | Verify that receiver can improve paket loss problems using duplication / reordering. | (Technical Risk ) How to check and recover Data drop (Availability QA) System maintain call quality under amount of increated data drop |
