Responsibilities：
As a Software Engineer Intern, your role encompasses three key areas.
- In the research and exploration phase, you'll study the FusionCDN system's traffic scheduling mechanisms, IPT cost model, and operational constraints. You'll also conduct a literature review on CDN - related optimization strategies and work with the team to define project objectives, constraints, and key performance indicators. This involves identifying challenges like high costs during peak periods and devising strategies to maximize free bandwidth.
- The data collection and analysis phase is crucial. You'll gather historical traffic data to identify peak periods and patterns, and build a simplified cost model for IPT charges. By analyzing traffic characteristics and running simulations on different traffic distribution scenarios, you'll gain insights that will inform the subsequent design work.
- In the traffic scheduling framework design and implementation phase, you'll design and implement an algorithm to redistribute traffic during peak periods, making the most of the free bandwidth without exceeding the limit. You'll then test and validate the solution in a controlled environment, evaluating its cost - savings, service quality, and scalability. This includes comparing IPT costs before and after implementation and assessing metrics like latency and throughput.
Minimum Qualifications：
- Currently enrolled in a Phd program in Computer Science, Electrical Engineering, or related fields.
- Strong background in networking, CDN systems, and traffic optimization.
- Experience with programming languages like Go, Python, or similar.
- Knowledge of algorithm development, cost modeling, and real-time systems is a plus.
