Abstract:
1. A communication management system comprising: a first system packet transfer board including a controller and a function unit; a second system packet transfer board including a controller and a function unit; a first system packet processing board including a controller and a function unit; a second system packet processing board including a controller and a function unit; a communication control board Including a controller; a first system switch board connected to the communication control board, the first system packet transfer board, the second system packet transfer board, the first system packet processing board, and the second system packet processing board; and a second system switch board connected to the communication control board, the first system packet transfer board, the second system packet transfer board, the first system packet processing board, and the second system packet processing board; wherein the controller of the communication control board comprises: a failure detector configured to detect at least one of a failure in the first system packet transfer board, the first system packet processing board, and the first system switch board; a function setting information storing unit configured to store function setting information needed to execute functions of the function unit of the first system packet transfer board and the function unit of the first system packet processing board; a system switching controller configured to, upon detection of a failure in one or more of the first system packet transfer board, the first system packet processing board, and the first system switch board, output a system switching instruction to said one or more of the second system packet transfer board, the second system packet processing board, and the second system switch board, corresponding to the board in which the failure has occurred; and a function setting unit configured to provide the corresponding function setting information stored in the function setting information storing unit to one or both of the second system packet transfer board and the second system packet processing board that corresponds to the board in which the failure has occurred, wherein the first and second system switch boards includes: a control packet switching circuit connected to the control board, the first and second system packet transfer boards, the first and second system packet processing boards by a first connecting member; and a user packet switching circuit connected to the control board, the first and second system packet transfer boards, the first and second system packet processing boards by a second connecting member, which is physically different from the first connecting member.
