DBOL Only Cycle
---------------



The term "DBOL" (Designated Bypass Object Layer) refers to a specialized comp>=1)

BETA = 1.5
Smoothing factor for exp> instantaneous rate measurement (bytes/sec)
Updates the EMA rates for each user.
"""
global last_update_time
now = time.time()
dt = now - last_update_time
last_update_time = now

for uid, meas in new_measurements.items():
if uid not in user_stats:

Initialize EMA with first measurement

ema = meas
else:
ema_prev = user_statsuid'ema_rate'

Exp> `max_rate` -> block for some time or deny.



Step 3: For burst detection: check if number of requests in last `burst_window` > `burst_threshold`. Use same deque but with shorter window (e.g., 1s).



Step 4: To avoid false positives, apply exp> 0:

update running average of the request rate

current_rate = state.req_count / dt
state.smooth_rate = SMOOTHING current_rate + (1-SMOOTHING)state.smooth_rate


reset for next interval

state.last_time = now
state.req_count = 0

state.req_count += 1
count this request



decide whether to throttle

if state.smooth_rate > THRESHOLD:
return "Throttle"
or drop / delay the request

else:
return "Accept"



The algorithm:





It keeps a running estimate of how many requests per sec
