Community Identifiers for Automated Client Network Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual configuration of group identifiers in network devices for virtual network segmentation in VXLAN environments is complex and cumbersome, especially with large numbers of client devices, increasing setup complexity.
Innovation Solution
Automated segmentation of virtual networks using community identifiers, such as PAN IDs, assigned during authentication procedures based on shared secrets or user information, to group client devices and restrict interactions within defined communities.

Engineering Contradiction Analysis
1Reliability
If manual configuration of group identifiers is used for virtual network segmentation, then network security and isolation are achieved, but setup complexity and configuration overhead increase significantly
Solution Approach 1:
The system automatically assigns community identifiers to client devices based on their authentication credentials without requiring manual configuration. The network device autonomously groups devices into communities and enforces isolation policies, eliminating the need for administrators to manually configure group identifiers for each device while maintaining security requirements.
2Reliability
If manual configuration of group identifiers is used for virtual network segmentation, then network security and isolation are achieved, but configuration time and operational overhead increase
Solution Approach 1:
Community identifiers are assigned to client devices during the authentication phase before the devices join the virtual network. This preliminary assignment ensures that devices are pre-grouped into appropriate communities with proper security policies applied, eliminating the need for subsequent manual configuration and reducing overall setup time while maintaining security requirements.
3Ease of operation
If automated segmentation using community identifiers is implemented, then setup complexity and configuration overhead are reduced, but network isolation and security may be compromised
Solution Approach 1:
The network device continuously monitors community identifier assignments and enforces isolation policies by examining community identifiers in packet headers. When packets are received, the system automatically determines whether to forward or drop them based on community matching rules, providing real-time feedback that ensures network isolation is maintained despite automated assignment processes.

AI summary
In some examples, a system initiates an authentication procedure for a client device, and determines a group of client devices including the client device based on information associated with the client devices. The system assigns, to the client device, a community identifier as part of the authentication procedure, where the community identifier identifies the group of client devices that are able to communicate with one another over a virtual network.
