  • Patent number: 8356169
    Abstract: If the communication partner of a client node (A1a) is an encryption communication target node (C1), a DNS Proxy unit (A12a) in the client node rewrites a response to a name resolution request for the communication partner node of an application from the actual IP address of the communication partner node to a loopback address that changes depending on the communication partner. On the basis of the destination loopback address of a data packet transmitted from the application, a communication encryption module (A13a) in the client node identifies the communication partner and the encryption communication path to be used for communication with the communication partner. Hence, encryption communication can simultaneously be executed directly with a plurality of communication partner nodes by using the communication encryption module that operates as an independent process.

  • Patent number: 8355329
    Abstract: The packet relay device includes a clock generation portion adapted to generate a clock signal of prescribed frequency as a standard for operation of the packet relay device; a timer portion adapted to count up a timer value over a first number of clock cycles on the basis of the clock signal; a relay control portion adapted relay received packets while limiting to a prescribed amount of packets the amount of packets forwardable per a predetermined increment of the timer value; and a power control portion adapted to reduce the frequency of the clock signal to 1/n in order to reduce power consumption by the packet relay device. If the frequency of the clock signal has been reduced to 1/n by the power control portion, the timer portion counts up the timer value over a number of clock cycles equivalent to 1/n the aforementioned number of clock cycles.

  • Publication number: 20120195201
    Abstract: In a packet relay apparatus or bandwidth policing apparatus, when the bandwidth of a flow having a function to respond to a congestion notification surpasses a first threshold, a congestion notification is given to rewrite a value representing the congestion state of the network out of the packet headers of the packet received by the apparatus. The packet is dropped if the bandwidth of the flow surpasses a second threshold higher than the first threshold. One of the following, including packet drop, rewriting the value representing the priority level in the network out of the packet headers and altering the priority level in the apparatus is imposed on the packet when the bandwidth of the flows surpasses a second threshold higher than the first threshold.

  • Publication number: 20110058564
    Abstract: A network relay device includes a packet buffer for temporarily storing a received packet, and a packet buffer control section for changing an effective buffer number depending on the received amount of packet. When a traffic amount is small, the packet buffer control section reduces the power consumption by stopping the feeding of power or the supply of clock to a part of the packet buffers. The network relay device further includes plural table memories storing a table for deciding the transfer destination of packet, and a table memory control section for changing an effective table number according to a required number of table entries. When the required table entry number is small, the table memory control section reduces the power consumption by stopping the feeding of power or the supply of clock to a part of the table memories.
