Route Table Ingress Association for Isolated Network Traffic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtualization technologies do not effectively allow for customizable and secure handling of network traffic within provider networks, limiting the integration of advanced security features and network appliances in logically isolated networks.
Innovation Solution
Associating route tables with ingress traffic to logically isolated networks enables the use of custom network appliances and service chains, allowing for optimized traffic routing and security by directing network packets through specific network appliances without modifying their destination fields.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If virtualization technologies are used to share computing resources among multiple customers, then resource efficiency and security are improved, but customization of network traffic handling is limited
Solution Approach 1:
The patent segments network traffic handling by introducing logically isolated networks (VPCs) that divide the provider network into separate, customizable virtual networking environments. Each VPC can have its own routing tables, network appliances, and traffic handling rules, allowing customers to customize network traffic handling without affecting other customers or the underlying substrate network complexity.
2Reliability
If advanced security features and network appliances are integrated into logically isolated networks, then security and traffic optimization are improved, but device complexity increases
Solution Approach 1:
The patent introduces route tables as an intermediary layer between the substrate network and logically isolated networks. These route tables act as mediators that enable integration of advanced security features and network appliances without directly increasing substrate network complexity. The route tables provide a standardized interface for customers to configure security rules and traffic optimization policies within their VPCs.
Solution Approach 2:
The patent adds a virtual networking dimension above the physical substrate network. By introducing VPCs with their own routing tables and network appliances, customers can implement advanced security features and traffic optimization in this new virtual dimension without complicating the underlying physical network infrastructure.
3Ease of operation
If route tables are associated with ingress traffic to logically isolated networks, then traffic routing control is improved, but system complexity increases
Solution Approach 1:
The patent creates universal route tables that can be applied across multiple logically isolated networks and different ingress traffic sources. This multi-functional routing mechanism allows customers to control traffic routing in their VPCs using standardized route table configurations, improving ease of operation without proportionally increasing system complexity through repetition.

AI summary
Route tables may be associated with ingress traffic for logically isolated networks. A routing device at the edge of a logically isolated network may receive a route to include in a route table that is associated with ingress traffic to the logically isolated network to forward the ingress traffic to a network appliance hosted in the logically isolated network. Network packets received at the edge routing device may have a destination of a computing resource hosted in the logically isolated network. The edge routing device may identify the route in the route table to override the destination in the network packet with the network appliance and forward the network packet to the network appliance according to the route.
