摘要： Provided is an operational status testing apparatus and method for an Ethernet-based APS process. A test command signal which contains a command to perform an operational test for the APS process of a first node and a second test response signal that indicates that the operation of the APS process of a second node is performed normally, from among far end request signals that are received from the second node connected to own first node via an Ethernet network, are filtered. When the far end request signals are test command signals, a first test response signal that indicates that the operation of the APS process of the first node is performed normally is generated, and a top priority local request signal is selected based on priorities of the first test response signal and at least one local request signal that indicates the status of the APS process of the first node, and an output signal to be transmitted to the second node is determined based on priorities of the top priority local request signal and the filtered the far end request signal. The function for testing the operational status for the APS process defined in ITU-T recommendation G.8031 is embodied, and when an operational status test request is received from another node, the APS process can be tested effectively without having to perform a complicated diagnosis operation for the APS process.

摘要： An address resolution protocol (ARP) processing method for Ethernet matching is provided in which a message authentication code (MAC) request message including IP information is received from another application module and provides a MAC corresponding to the MAC request message, the method including: determining whether a MAC matching the IP information included in the MAC request message is stored; determining whether the MAC request message includes Ethernet over synchronous optical network/synchronous digital hierarchy (SONET/SDH) (EoS) channel information; if it is determined that the MAC request message does not include EoS channel information, detecting EoS channel information that is previously stored and that matches the IP information; and broadcasting an ARP request message to an external host via an EoS channel. The ARP processing method is performed using the EoS channel, thereby reducing unnecessary broadcast traffic packets.

摘要： Provided is a network resource provisioning method for bandwidth guarantee per flow in a differentiated service Internet in which bandwidth needed for each flow is individually requested. The method includes setting an optimum path between a source node and a destination node based on a request for traffic for a specific period of time; performing static provisioning in which bandwidth is allocated to the optimum path according to a service class thereof; determining whether all of the bandwidth allocated to the optimum path by performing static provisioning are used up, and accepting connection admission according to the determination result; and when connection admission is not accepted, performing dynamic provisioning in which additional bandwidth is allocated to the optimum path based on a request for traffic from a new incoming flow. Accordingly, it is possible to efficiently provide a quality-guaranteed service by accepting a request for bandwidth per flow.
