| # FL parallelism## Goals- Have the ability to move FL instance closer to switch- Remove Single point of failure- Distribute the load to multiple instances (horizontal scale)- Do high load testing## The ideaCreate more topic for distributing messages to FL and use Storm as therouter. Each FL instance has separated input/output topic forcommunicating with Storm. When Switch connected to FL, and we have aswitch_add message we save switch_id to FL instance mapping. New Stormtopology collects all messages from all FL instances and sends it toone topic for further processing. In case of sending a message to FLsender writes a message to a common topic and New Storm topology getsthat message and resends it to the corresponding topic.## Affected- All calls to FL without switch id for example get all switches.## Diagrams | |||
