Traffic-shaping algorithm
A traffic-shaping algorithm controls the rate, volume, or distribution of traffic to conform to specified limits or routing rules.

Shaping is a quality-of-service technique that enforces a traffic rate limit by buffering excess traffic and transmitting it later at the permitted rate.
- How it is used
- Controls traffic rates in QoS policies when excess traffic should be delayed rather than dropped.
- How deep it goes
- Defines buffering, queues, conforming traffic, exceeding traffic, scope, and bursts, but provides no CLI syntax or verification output.
- Examples
- Uses a 300 Mbps ISP connection, GigabitEthernet interfaces, provider policing, and customer outbound shaping.
- What you can do after
- Apply shaping to smooth traffic and avoid drops caused by a downstream provider’s rate limit.
Python Concurrency with asyncio
Traffic shaping is the control of network traffic volume or rate to conform to specified limits.
- How it is used
- Limits API request bursts when concurrency control alone could create spikes of load.
- How deep it goes
- Contrasts concurrency limiting with rate shaping and names two algorithms, but stops short of implementing either.
- Examples
- Uses ten concurrent requests as a semaphore example and identifies simultaneous bursts as the problem to shape.
- What you can do after
- Evaluate whether a semaphore is sufficient or whether a leaky-bucket or token-bucket design is needed.
