Rate Limiter And Source limiter •

•

Rate limiter ensures that number of packets reach to application should be less then application can handle efficiently. And source limiter monitor every end points and limit each end point to send only required packets to server or to user. Rate limiter and source limiter prevent and report the DOS & DDOS attack where attacker send the packets from one IP or by continuously changing it’s identity( From different IP addresses hence difficult to identify) to server or to any user with the intention of exhausting server resources which lead to service available to the Users.

Server is under DDOS Attack

Register

Both calls completed During the DDOS Attack Bob calls to Alilce and John calls to his Bos
