Abstract
An apparatus of determining blocking in an Ethernet ring network sets blocking with respect to each of the plurality of links in an Ethernet ring network, and determines one of the plurality of links as a link to be blocked by using traffic request amounts of a plurality of service flows with respect to the respective links set to be blocked.
Claims20
A method of determining logical blocking by a blocking determining apparatus of an Ethernet ring network in which nodes are connected by links, the method comprising:
- setting blocking with respect to each of a plurality of links in the Ethernet ring network and calculating a traffic request amount of a plurality of service flows in the Ethernet ring network;
- determining one of the plurality of links as a link to be blocked based on the traffic request amounts calculated according to the setting of blocking of each link;
- and
- blocking one of two ports connected through the blocked link.
An apparatus of determining blocking in an Ethernet ring network in which nodes are connected by links, the apparatus comprising:
- a calculation unit configured to set blocking with respect to each of the plurality of links in the Ethernet ring network, and calculate traffic request amounts of the plurality of service flows with respect to each of the links set to be blocked;
- and
- a determining unit configured to determine one of the plurality of links as a link to be blocked by using the traffic request amounts of the plurality of service flows with respect to the respective links set to be blocked.
An apparatus of determining blocking in an Ethernet ring network in which nodes are connected by links, the apparatus comprising:
- a calculation unit configured to set blocking with respect to each of the plurality of links in the Ethernet ring network, and calculate a capacity of each of the links set to be blocked with respect to the plurality of service flows by using traffic request amounts of the plurality of service flows;
- and
- a determining unit configured to determine one of the plurality of links as a link to be blocked by using the capacity of each of the links set to be blocked.
