In order to resolve network failures, some sort of facility to handle line redundancy of the transmission paths is required.
However, depending on how a network is used, there are different ways of connecting to networks and simply gathering redundant lines complicates the system itself, which in turn makes operating and managing systems more complicated. In addition to this, program developers must undertake extra work, such as designing and developing methods to detect and resolve network failures.
By installing GLS, you avert such potential problems and can set up a network system characterized by high degrees of fault tolerance, availability, and reliability. You can also ensure that applications communicating through TCP/IP continue to operate smoothly without having to worry about finding redundant transmission paths or network failures in transmission paths.
