Hi Yunfei
 
(2)   “ Malicious peers may issue denial of service attack to the trackers by
   sending large amount of requests with tracker protocol. Distributed
   trackers deployment may alleviate the problem.”
 
CS: Can you please explain, why you are in the opinion, that distributed trackers can alleviate the problem? It even could increase the problem, because now you can attack the distributed parts of the tracker simultaneously. Which makes thinks worse.
 
Yunfei: The rational is that distributed trackers disperse the DoS attack to a specific tracker in centralized tracker senario. Therefore the attack to one certain tracker is alleviated.Does it make sense?
 
CS: I see, what about the following text proposal:
 
(2)   “ Malicious peers may issue denial of service attack to the trackers by
   sending large amount of requests with tracker protocol. In case of a distributed
   tracker the attack to some of these entities may not interrupt the service.”
 
Best Regards
Christian
