Definitions
- the present invention relates to a method for distributing configurations of network devices. Such a distribution of configurations according to the invention can be used to automatically configure network devices without configuration, for example newly used replacement devices.
- EP 0 241 878 A2 discloses a method for self-configuration in networks designed in the form of a ring. This determines which devices are present in the ring-like network so that a corresponding request can be made when a device is replaced. To configure the new device, a corresponding configuration must then be sent to the new device via the network.
- WO 2008/082587 A1 discloses a further method for the configuration of network devices, in which case parameters for the correct use of the network are transmitted. This happens when requested by the network device to be reconfigured. Corresponding peripheral devices connected to the network device are not taken into account.
- the object of the present invention is therefore to provide a method for distributing the configuration of network devices in which the configuration is not only stored locally on the network device to be exchanged and can thus be called up and used by an exchange device after the network.
- a method is proposed with at least one network to which network devices can be connected. All are suitable as network devices Types of devices that have a network connection, which network connection could be wired or wireless. Thus, computers, tablets, printers, scanners, routers, monitors or televisions are examples of network devices.
- the method according to the invention requires at least two network devices which are connected to the network via ports.
- the network devices can have several ports via which further peripheral devices can be connected.
- the network devices are provided with a definable, unambiguous identification.
- This can be a simple name, a Mac address or an ID.
- a memory is assigned to at least one of the network devices connected in the network. This memory can be used to save and read the required configurations of the network devices. These memories are non-volatile and are provided in addition to the local memories of the network devices.
- the network device to be configured has means for determining its location. The location of this network device is determined by these means of location determination.
- the position can be determined by a topological fingerprint or by the fact that the neighboring devices of the network device to be configured know which device was connected to the position to be configured.
- a topological fingerprint is understood to be a character string that can be interpreted, for example, as the file name of a configuration file. The configuration of the device is then contained in the file.
- the port numbers of the network device to be configured, under which the neighboring network devices are connected can also be read out.
- the character string used in this way then consists of the port numbers used and the identifiers of the neighboring network devices connected to the port numbers.
- Configuration file can be interpreted, that can be configured
- Network device clearly create a special configuration file and first save it locally.
- a storage of the configuration file in a memory of the further network devices is provided according to the invention.
- Network devices their own identifier is stored so that the neighboring network devices know the network device to be configured and their own position can be determined.
- the respective configuration is stored on the memory of another network participant, including the location.
- provision can also be made for a specific network subscriber or that the configuration is distributed so that it is then available on multiple memories of the network devices.
- the network device on whose memory the configuration is saved can be determined according to certain rules. For example, one rule could be to first select those neighbors who themselves have the fewest neighbors. This means that devices with many neighbors do not have to save many configuration files.
- the configuration file is transferred to the corresponding device (s) and stored there in a non-volatile manner.
- the storage takes place in copy in addition to the local storage of the configuration file, as known from the prior art. If there is a server in the network, it can also be specified as a rule that the configuration files are stored centrally on the server.
- the configuration files can be saved according to a specified schedule or every time a network participant experiences a configuration change.
- a network device fails, it must be removed and replaced with a fresh network device at the same location so that all connections that the defective device had are re-established in the same way. In this case, the replaced device recognizes that there is no configuration and exchanges information the other network devices in the network in order to access the configuration file intended for him.
- the storage of the configuration files can be encrypted in a special embodiment. It can also be compressed to save storage space.
- the compression and encryption can also be carried out in combination.
- P2P point-to-point protocol
- this protocol is used to send the configuration file to be saved to the relevant participant and, if necessary, to read it out again.
- Corresponding protocols for this are sufficiently known from the prior art.
- At least one display be provided and that parameters be generated for the states of the individual network devices, which parameters can be visualized on the display. This means that the status of the network devices and / or the configurations can be made visible on the display at any time.
- the aforementioned generated parameters can in particular contain how often and on which network devices a configuration is stored, whether the configuration files with the same name have the same content, the number of network devices involved in the process, free and used memory of the network participants and / or a table of neighboring ones Network devices and their status.
- the configuration files are then stored on the server according to a rule and retrieved from it.
- the communication protocol is not only a P2P protocol, but that the extended neighborhood of network devices can also be included. This can be achieved by having a log field, for example a
- Transmission level contains (TTL - "time-to-live”).
- the sender of the protocol message then sets this value to 2, for example, in order not to reach the next network device in the immediate vicinity of the sender, but the next but one.
- the first recipient of the message and thus a direct neighbor of the sender checks whether the message contained in the message Value is greater than 1. If this is the case, it forwards the message to all other ports and at the same time reduces the TTL value by one.
- the subsequent recipient of the message recognizes the 1 in the log and answers the message accordingly. This allows the sender of the message to determine whether the direct neighbor or more distant network devices should be queried or addressed.
- the original TTL value When using such a protocol field, the original TTL value must also be retained in the protocol, so that when the corresponding network device responds, this value can be used for the protocol packets of the response in order to reach the sender of the message in the opposite direction.
- the advantages achieved with the invention are, in particular, that the use of an additional component per network device can be dispensed with, by means of which the configurations are stored on existing neighboring devices or possibly a server. This can save costs.
- the device to be exchanged only has to be connected in the same way to the separate connections of the exchanged device in order to be able to be recognized with the claimed method and provided with a configuration.
- FIG. 1 a method according to the invention for distributing configurations in networks.
- FIG. 2 a method according to the invention for distributing configurations in networks from FIG. One, but with an additional network device as a server.
- FIG. 1 shows a network 11 for using the method according to the invention for distributing the configuration of network devices 1, 2, 3, 4, 5, 6, 7.
- the network 11 shown is partly ring-shaped, but partly star-shaped. To use the method according to the invention, however, it is not necessary to have a specific network topography.
- the method can be used in well-known networks, Network devices 1, 2, 3, 4, 5, 6, 7 are provided in network 11.
- the network connections themselves are implemented via ports 9 so that every network device 1, 2, 3, 4, 5, 6, 7 could access every other network device 1, 2, 3, 4, 5, 6, 7.
- At least one network device 5 in FIG. 1 also has a memory 10.
- data for example as files, can be stored and read out.
- the memory 10 is to be viewed in addition to the focal storage possibilities of each network device.
- the network devices 1, 2, 3, 4, 5 shown in FIG. 1 can be, for example, network routers or hubs to which the two computers 6, 7 are connected, for example.
- the method is not limited to this type of network device. Rather, all types of network devices can be used.
- At least one network device 1, 2, 3, 4, 5, 6, 7 is equipped with means for determining its location.
- the at least one network device 1, 2, 32, 4, 5, 6, 7 is localized by this means of determining the location, so that its defined location is present in the network 11.
- the method now proposes that the configuration of the at least one network device 1, 2, 3, 4, 5, 6, 7, taking into account the location that was read out by the location determination means, is stored on the memory 10 of another network device 1, 2, 3, 4, 5, 6, 7 is saved. If, for example, the method is to be carried out for the network device 4, the location of the network device 4 is determined by the location determination means and the configuration of the network device 4 is stored on the memory 10 of the network device 5.
- FIG. 1 only one (5) of the network subscribers 1, 2, 3, 4, 5, 6, 7 is equipped with a memory 10.
- more storage options are also conceivable, as shown in FIG. 2, among other things. So that it can be determined which network device 1, 2, 3, 4, 5, 8, 7 is provided with memories 10 and on which memory 10 the configurations can be stored, rules for the method according to the invention can be defined. These rules then clearly define which memory 10 must be accessed in order to store or read the configurations.
- exemplary network device 4 fails because it has a defect or shows other malfunctions, it must be exchanged for a device of the same construction, fresh from the factory. The location of this new device is then determined, also using the aforementioned method. Since there is no configuration for the new device, an attempt is made to find a corresponding configuration. For this purpose, the network device 4 to be configured is identified by means of the position determination as well as its associated configuration file, namely taking the position into account. This is read out from the corresponding memory 10 via the aforementioned rules and applied in the network device 4.
- FIG. 2 shows the presence of a server 8 for the other network devices 1, 2.3.4.5, which also has a memory 10.
- a network 11 with two memories 10 is thus shown.
- Corresponding rules can now be used to define the memory 10 on which the configurations are stored.
