Track Overview Figure 363 Collaboration through the Track module
The Track module is used to implement collaboration between different modules.
The collaboration here involves three parts: the application modules, the Track
module, and the detection modules. These modules collaborate with one another
through collaboration objects. That is, the detection modules trigger the
application modules to perform certain operations through the Track module.
More specifically, the detection modules probe the link status, network
performance and so on, and inform the application modules of the detection
result through the Track module. After the application modules are aware of the
changes of network status, they deal with the changes accordingly to avoid
communication interruption and network performance degradation.
The Track module works between the application modules and the detection
modules and is mainly used to obscure the difference of various detection modules
to provide a unified interface for application modules.
