The importance of app optimization for slow devices

Poor app performance on slow devices like home gateways leads to user frustration and abandonment, making optimization crucial for success.

#2about 4 minutes

How backend systems communicate with home gateways

Communication with home gateways relies on an Auto Configuration Server (ACS) using the slow and unstable CWMP protocol with TR-181 commands.

#3about 4 minutes

Backend strategies for managing slow, unstable devices

Implement backend retry policies, multi-level caching, and asynchronous communication to improve the stability and speed of interactions with home gateways.
