Remote Probing for Network Failover Resource Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network failover designs often lead to inefficient use of resources due to reservation of capacity for potential failover traffic, especially when network devices at standby locations are not directly impacted by failures.
Innovation Solution
Implementing remote probing for failover services, where network devices at standby locations receive and return failover traffic to the failover location, allowing both locations to utilize resources efficiently and minimizing unnecessary resource reservation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network devices at standby locations reserve capacity for potential failover traffic, then network reliability is improved, but resource usage efficiency deteriorates
Solution Approach 1:
The patent implements remote probing that performs preliminary detection of failover traffic conditions before actual failover occurs. Network devices at standby locations remotely probe for failover traffic only when needed, rather than continuously reserving capacity. This preliminary action approach maintains reliability by detecting failover conditions in advance while avoiding unnecessary resource consumption during normal operation.
2Loss of time
If network devices at standby locations continuously monitor for failover traffic, then failover response time is improved, but resource consumption increases
Solution Approach 1:
The patent implements periodic remote probing where network devices at standby locations monitor for failover traffic at specific intervals rather than continuously. The probing is triggered periodically or event-driven, allowing the system to maintain adequate failover response time while significantly reducing resource consumption compared to continuous monitoring approaches.
3Stability of the object's composition
If capacity is reserved at standby locations for failover traffic, then network stability is improved, but device complexity increases
Solution Approach 1:
The patent extracts the failover traffic handling function from the standby location network devices and relocates it to a centralized remote probing system. Instead of each standby device maintaining complex failover monitoring capabilities and reserved capacity, the system uses a centralized remote probing mechanism that simplifies individual device complexity while maintaining overall network stability through coordinated failover detection and routing.
Data Source
AI summary
A method, a device, and a non-transitory storage medium are described in which a remote probing for failover service is provided. The remote probing for failover service includes receiving, by a network device at a standby location associated with a geographic redundancy, failover traffic, which originates at a primary location of a network. The network device routes the failover traffic back to a corresponding network device at the primary location. The network device at the primary location may provide the failover traffic to a network performance analyzer device at the primary location.
