In the age of AI agents,
API traffic control is essential
This is more than blocking requests because volume is high.
AI-native architectures are changing the very paradigm of traffic management.
NetFUNNEL API is an API traffic-control solution that stores API requests exceeding processing capacity in a loss-free queue, then processes them sequentially according to available capacity and priority.
Conventional traffic control
cannot handle AI agents
A single request fans out into hundreds of internal calls, and response times swing from milliseconds to minutes. RPS-centric rate limiting is already showing its limits.
LLM agent traffic
- Recursive calls where AI invokes AI
- One request → hundreds of internal calls
Unpredictable processing time
- Milliseconds → explosive swings up to minutes
- Legacy rate limiting cannot respond
Token-based cost structure
- Traffic control by TPM, not RPS
- Context size drives infrastructure cost
One request can fan out into hundreds —
keep API traffic flowing
An era where one external LLM delay from an AI agent's recursive calls can paralyze the entire backend.
NetFUNNEL controls the inflow and usage of server-to-server API requests to match your system's processing capacity, reducing the risk of overload.
Beyond fixed values,
real-time resource-based control
Fixed rate limits use resources inefficiently and fail to reflect the server's real state. NetFUNNEL watches CPU, memory, response time, and tokens in real time to adjust the flow dynamically.
Limitations of traditional rate limiting
Because values are fixed, resources are inefficient, the server's real state is ignored, and every environment change requires manual tuning.
- Fixed values → resource inefficiency
- Real server state ignored
- Manual tuning on every change
How NetFUNNEL solves it
It controls dynamically based on real-time server resource metrics, staying in Bypass normally and switching to automatic filtering only under load.
- Real-time resource-based control
- Bypass normally → auto-filter under load
- Based on AI API tokens and response time
Keep critical APIs available —
even under load
When traffic surges, you cannot handle every request equally. By assigning priority per URI, header, and tier, we protect the availability of critical APIs and VIP traffic first.
Control every traffic flow from one screen
Total requests, completed, waiting, and blocked — every traffic state shown in real time.
When anomalies are detected, a single console lets you act immediately.
Without manual intervention,
the system adjusts on its own
It monitors system resource metrics in real time,
activates the queue automatically the moment thresholds are crossed,
and resumes sequential processing once the load eases.
Operators never have to touch the thresholds.
Even when AI responses slow down,
the service never stops
A mere 2-second external LLM delay can push the entire internal server into a Blocking state.
NetFUNNEL automatically reduces inflow the moment it detects rising response times, then expands throughput again once things normalize.
Frequently Asked Questions
Common questions before getting started. Reach out anytime to learn more.
NetFUNNEL API is an API traffic-control solution that, instead of immediately rejecting API requests beyond the system's processing capacity, holds them in a queue and processes them sequentially according to available capacity and configured policies. If current throughput is within the configured admission rate, requests are processed immediately; a waiting policy applies only when processing capacity is exceeded. This reduces the loss of legitimate API requests during traffic surges and prevents backend overload.
