Abstract
A network management system is provided in which a transmission band for preceding access is guaranteed even when simultaneous access to shared data is obtained by plural nodes and which does not suffer any problem even in the case of accessing to data that requires real-timeness such as with video data. In order to guarantee an I/O band for a hard disc and a band for the network when simultaneous access by plural nodes to shared data is obtained, an access manager for controlling access bands is provided inside the system, which guarantees a transmission band for preceding access on the occasion of simultaneous access by plural nodes by making mode-of-access judgment, managing the network band and the hard disc I/O transmission band, and judging whether or not to approve the access based on whether or not the bands are saturated.
