Protecting Network Quality of Service Against Denial of Service Attacks

摘要

As quality of Service (QiS) capabilities are added to the Internet, our nation's business and research infrastructure will increasingly depend on their fault tolerance and survivability. Current frameworks and protocols (such as the Resource ReSer Vation Protocol (RSVP), Integrated Services (lntServ), and Differentiated Services (DiffServ)) that provide quality of service to networks are vulnerable to attacks of abuse and denial of service. Once QoS mechanisms are deployed, they will become tempting targets for malicious hackers or adversaries. It is wise to anticipate such attacks and develop effective and practical defenses prior to widespread deployment.
