20090119550 | IMAGE FORMING APPARATUS AND ANALYSIS METHOD - A sufficient number of packets necessary for analysis of a fault in a network communication apparatus are obtained. A multi function peripheral (MFP) temporarily stores received packets as a file for every print job, and stores communication failure information as a log (communication failure log). The MFP deletes data in which no error has occurred in an application among the stored files. Then, in a case where an error has occurred during processing of a certain print job, the MFP stores received packets in a storage device, and compares a communication failure in the job packet in which the error has occurred with a communication failure in packets associated with all the received print jobs. As a result of the comparison, the MFP extracts a communication failure in only the job packet in which the error has occurred, and creates a log so that the extracted result can be identified. | 05-07-2009 |
20090248890 | COMMUNICATION APPARATUS, CONTROL METHOD THEREFOR, AND STORAGE MEDIUM - A communication apparatus, which has a normal power consumption mode and a power saving mode lower in power consumption than in the normal power consumption mode and which is connected to a network via a network interface device, communicates with a device on the network via the network interface device. The communication apparatus acquires capability information indicating a communication capability of the device, and based on acquired capability information, determines a communication mode to be used when the network interface device communicates with the device under a condition that the communication apparatus has shifted to the power saving mode, and when the communication apparatus shifts from the normal power consumption mode to the power saving mode, sets the determined communication mode as a communication mode to be used when the network interface device communicates with the external device. | 10-01-2009 |
20090287941 | INFORMATION PROCESSING APPARATUS, CONTROL METHOD THEREFOR, AND STORAGE MEDIUM - An information processing apparatus which makes it possible to store encrypted data of packets in a decrypted state, and improve the efficiency of data analysis. A network interface receives encrypted data which has been encrypted, and data which has not been encrypted, from a network. A HDD stores received data. A IPSec module is operable when an item of the received is an item of the encrypted data, to decrypt the item of the encrypted data. A packet acquisition sub application searches the data stored in HDD for an item of the encrypted data corresponding to an decrypted item of data. The packet acquisition sub application updates the item of the received encrypted data based on the decrypted item of the data. | 11-19-2009 |
20100229030 | COMMUNICATION APPARATUS AND CONTROL METHOD THEREOF - A communication apparatus stores a first address in association with a second address of an apparatus which is targeted to permit or restrict processing of a received packet. The communication apparatus detects first and second addresses of a transmission apparatus which is a source of a packet received through a network, and if the detected first address of the transmission apparatus is stored, then the processing of the received packet is permitted or restricted. If the detected first address of the transmission apparatus is not stored in association with the second address of the transmission apparatus and the detected second address is stored, then the communication apparatus updates the stored first address with the detected first address. | 09-09-2010 |
20100262691 | INFORMATION PROCESSING APPARATUS, NETWORK INTERFACE DEVICE, CONTROL METHOD THEREFOR, AND STORAGE MEDIUM - An apparatus stores address information of a server and transmits information of an apparatus to the server at a regular interval. The apparatus, when shifting from a normal state to a power-saving state, keeps continued regular transmission, by notifying a network interface device of the stored address information and the information of the apparatus. | 10-14-2010 |
20110080910 | COMMUNICATION APPARATUS HAVING A PLURALITY OF NETWORK INTERFACES, METHOD OF COMMUNICATION BY THE COMMUNICATION APPARATUS, AND STORAGE MEDIUM - A communication apparatus which is capable of performing multicasting or broadcasting using a user-desired network interface. An MFP implementing the communication apparatus includes a plurality of network interfaces and performs multicasting or broadcasting via at least one of the network interfaces. A controller unit provides an application programming interface to an application that operates on the MFP. An operator of the MFP operates an operation unit to set a transmission condition for transmitting a multicast packet and a broadcast packet via a predetermined network interface. When a plurality of active network interfaces are detected, one of the plurality of detected active network interfaces which satisfies the set transmission condition is selected and multicasting or broadcasting is performed via the selected network interface. | 04-07-2011 |
20110082923 | COMMUNICATION APPARATUS HAVING A PLURALITY OF NETWORK INTERFACES, METHOD FOR CONTROLLING THE COMMUNICATION APPARATUS, AND STORAGE MEDIUM - A communication apparatus having a plurality of network interfaces and capable of properly returning MIB information requested by an external apparatus, even when a network interface actually in communication with the external apparatus and a network interface designated by the external apparatus are different. If it is determined that a value of interface information contained in a MIB information retrieval request received by a communication unit from an external apparatus is a predetermined value and a first network interface has received the request, information corresponding to the first network interface is created from the MIB information and returned to the external apparatus. If it is determined that the value is the predetermined value and that a second network interface has received the request, information corresponding to the second network interface is created from the MIB information and returned to the external apparatus. | 04-07-2011 |
20110216343 | COMMUNICATION APPARATUS, CONTROL METHOD THEREFOR, AND STORAGE MEDIUM - A communication apparatus, which has a normal power consumption mode and a power saving mode lower in power consumption than in the normal power consumption mode and which is connected to a network via a network interface device, communicates with a device on the network via the network interface device. The communication apparatus acquires capability information indicating a communication capability of the device, and based on acquired capability information, determines a communication mode to be used when the network interface device communicates with the device under a condition that the communication apparatus has shifted to the power saving mode, and when the communication apparatus shifts from the normal power consumption mode to the power saving mode, sets the determined communication mode as a communication mode to be used when the network interface device communicates with the external device. | 09-08-2011 |
20120110357 | COMMUNICATION APPARATUS, METHOD OF CONTROLLING THE SAME, AND STORAGE MEDIUM - A communication apparatus that is capable of communicating with network nodes more properly even when a control unit thereof shifts to a power-saving state. An NIC communicates with the network nodes via a network. The controller communicates with the network nodes via the communication unit. The controller stores node information on a network node that has transmitted data satisfying a predetermined condition, determines whether or not a shift condition for shifting the controller to a power-saving state is satisfied, and notifies the communication unit of the stored node information when it is determined that the shift condition is satisfied. The NIC stores node information notified by the controller, and executes communication processing based on the stored node information when the controller is in the power-saving state. | 05-03-2012 |
