Discovery Agent Proxy Server Load Balancing via Dynamic Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional agentless discovery methods face challenges in managing dynamic proxy server activations and deactivations, leading to issues with connectivity and load balancing in network management systems, which can result in disrupted communication and inefficient resource utilization.
Innovation Solution
Implementing agent-based discovery with discovery agents that receive a registration payload listing available proxy servers, allowing them to dynamically select the best proxy server based on response time and load, ensuring nearly uninterrupted connectivity and balanced load distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If preconfigured proxy server addresses are used by discovery agents, then initial connectivity can be established, but connectivity is disrupted when proxy servers are activated or deactivated frequently
Solution Approach 1:
The discovery agent implements a feedback mechanism by periodically testing connectivity to proxy servers and receiving updated registration payloads from the computational instance. When a proxy server becomes unavailable, the agent detects this through connectivity tests and receives updated proxy server lists from the computational instance, allowing it to adapt to dynamic changes in proxy server availability.
Solution Approach 2:
The system transitions from static preconfigured proxy server addresses to dynamic proxy server selection. The discovery agent maintains a list of available proxy servers that is periodically updated by the computational instance, allowing the agent to dynamically adapt to proxy server activations and deactivations rather than relying on fixed configurations.
2Reliability
If all discovery agents connect to the same available proxy server, then connectivity is maintained, but load on the proxy server becomes unbalanced
Solution Approach 1:
The system segments the proxy server connections by distributing discovery agents across multiple available proxy servers. Instead of all agents connecting to a single proxy server, the computational instance provides multiple proxy server options in the registration payload, and agents are distributed across these servers, balancing the load and improving overall system efficiency.
3Reliability
If discovery agents perform connectivity tests to all proxy servers, then optimal proxy server selection is achieved, but time and computational resources are consumed
Solution Approach 1:
The discovery agent performs partial connectivity tests by testing only a subset of proxy servers rather than all available proxy servers. The agent receives a registration payload with multiple proxy server options and performs connectivity tests on selected servers to determine the best available proxy, balancing selection quality with time and resource consumption.

A non-transitory computer readable storage medium may have stored thereon instructions that, when executed by an endpoint device, cause the endpoint device to perform operations including: (i) establishing, by the endpoint device, a first communication channel with an intermediary proxy server; (ii) receiving, from a computational instance and via the intermediary proxy server, a registration payload comprising a list of available proxy servers; (iii) ranking, at the endpoint device, the list of available proxy servers; (iv) selecting, by the endpoint device, a particular proxy server from the list of available proxy servers as ranked; (v) establishing, by the endpoint device, a second communication channel with the particular proxy server; and (vi) communicating, by the endpoint device, with the computational instance via the particular proxy server by utilizing the second communication channel.
