The RFP server may transmit an anti-attack packet towards a source IP address that has been identified as initiating a DoS IP attack. The anti-attack packet may include an Explicit Congestion Notification (ECN) value that echoes congestion to the source IP address, thereby alerting the source IP address that the RFP server is aware of the intended DoS IP attack. Further, the RFP server may generate, modify, and share filter criteria with one or more MGM node(s) of a multicast network, thereby improving DoS IP attack detection capabilities across the multicast network. Filter criteria may include, but is not limited to, source IP address, destination IP address, file size of IP packets, and a frequency by which IP packets are delivered."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Real-time policy filtering of denial of service (DoS) internet protocol (IP) attacks and malicious traffic","description":"This disclosure describes techniques that facilitate dynamic filtering and blocking of Denial of Service (DoS) Internet Protocol (IP) attacks via a Real-time Filtering policy (RFP) Server.
