Route Advertisement Protocol for Network Security Capability Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network security systems lack effective mechanisms to communicate and utilize network security capabilities between different networks and nodes, leading to inefficient resource utilization and potential misuse of resources in filtering malicious traffic.
Innovation Solution
Extending route advertisement protocols to include network security capabilities information, allowing routers to advertise and direct traffic based on available threat detection and mitigation services, enabling informed routing decisions and efficient resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all traffic is analyzed for threats by a local NSS when network security capabilities are not shared, then network security is maintained, but expensive and limited NSS resources are inefficiently utilized and potentially wasted
Solution Approach 1:
The patent implements feedback mechanisms where NSS capabilities are advertised through route advertisement messages, allowing network nodes to receive information about available security services and make informed routing decisions that direct traffic to appropriate NSS resources, preventing both security gaps and resource waste
Solution Approach 2:
The patent introduces route advertisement messages as intermediaries that carry network security capabilities information between NSS and network nodes, enabling indirect communication and coordination without requiring direct complex interactions, thus improving both security reliability and resource utilization efficiency
2Productivity
If network security capabilities information is advertised through route advertisement messages, then resource utilization efficiency is improved, but device complexity increases
Solution Approach 1:
The patent extends existing route advertisement protocol messages to also carry network security capabilities information, allowing these messages to serve multiple functions (routing and security capability advertisement) simultaneously, thereby improving resource utilization without proportionally increasing system complexity
Solution Approach 2:
The patent modifies route advertisement messages by adding security capability parameters to existing protocol structures, enabling enhanced functionality through parameter extensions rather than creating entirely new complex communication mechanisms, thus balancing improved productivity with controlled complexity

AI summary
Methods, systems, and computer readable media for advertising network security capabilities are disclosed. According to one method, the method occurs at a network node. The method includes receiving a first route advertisement message that includes network security capabilities information indicating capabilities of a network security system associated with a route. The method also includes receiving a packet associated with a packet flow. The method further includes directing the packet associated with the packet flow to a downstream network node associated with the network security system.
