Embodiment approach 1

[0041] (Structure of remote management system)

[0042] figure 1 It is a figure which shows the remote management system of Embodiment 1 of this invention. The remote management system has an optical transmission device 1 , an operation terminal 2 and a management device 3 .

[0043] The optical transmission device 1 is, for example, a processing device that transparently stores a client signal such as 100GbE (Gigabit Ethernet) (Ethernet is a registered trademark) in an OTN frame, and transmits it to an optical transmission line superimposed on a laser beam as a carrier. Details of the structure of the optical transmission device 1 will be described later.

[0044] The operation terminal 2 is a computer device that instructs the optical transmission device 1 connected to itself to enable or disable a specific function installed in the optical transmission device 1 through an operation of an operator (hereinafter referred to as an operator). In addition, the operation terminal...

Embodiment approach 2

[0114] The configurations of the remote management system and the optical transmission device 1 (processing device) according to the second embodiment of the present invention are the same as those of the first embodiment. However, the structure of the device information and the function authentication key held by the information holding unit 11 is different from that of the first embodiment.

[0115] Figure 7-10 It is a diagram showing an example of information stored in the information storage unit of the optical transmission device according to Embodiment 2 of the present invention. Unlike Embodiment 1, the device status information and the function authentication key include the "license issuance count" which is a function authentication key issued separately for a plurality of functions installed in the digital coherent DSP-LSI 10 total.

Embodiment approach 3

[0162] The remote management system according to Embodiment 3 of the present invention is different from Embodiments 1 and 2. It also targets an optical transmission device 1 (processing device) in which a plurality of digital coherent DSP-LSI 10 is installed in one optical transmission device 1. The functions of the optical transmission device 1 are remotely set. In Embodiment 3, since the same function in a plurality of digital coherent DSP-LSIs 10 can be collectively set (validated or invalidated) using one function authentication key, it is possible to perform more flexible and low-cost remote management of the system. application of cost.

[0163] The structure of the remote management system of this embodiment is the same as that of Embodiment 1 figure 1 Similarly, the optical transmission device 1 (processing device) of this embodiment includes not only the figure 2 The configuration may also include a configuration in which a plurality of digital coherent DSP-LSIs 1...

Abstract

The processing device has a processing unit (12) having a plurality of functions. A holding unit (11) holds a device identifier capable of identifying a processing device. An interface unit (6) externally receives a function authentication key which is a code for setting a specific function among a plurality of functions to be valid or invalid. When the device identifier included in the received function authentication key matches the device identifier held by the holding unit (11), the control unit (13) sets the specific function to be valid or invalid according to the function authentication key .

Description

technical field [0001] The present invention relates to a processing device such as an optical transmission device and a remote management system for remotely managing the processing device. Background technique [0002] With the rapid popularization of broadband access that handles large-capacity data, communication services tend to increase year by year. In order to cope with the soaring communication business, the innovation of optical transmission technology is constantly carried out. In recent years, digital coherent optical transmission technology has been developed as a transmission technology that realizes a transmission capacity exceeding 100 Gbit / s per wavelength (see, for example, Non-Patent Document 1). [0003] The optical transmission device using the digital coherent optical transmission technology has, for example: a LAN interface part, which inputs and outputs client signals such as 100GbE (Gigabit Ethernet) (Ethernet is a registered trademark); Transmissi...
