Abstract
A method and apparatus for link discovery among domains, the method including receiving a link discovery packet from a second switch in a second domain, generating a response packet with respect to the link discovery packet, and transmitting the response packet to the second switch, wherein the link discovery packet is generated by a transmission controller to control the first domain in order to detect a link between the second switch and the first switch in a first domain.
Claims15
A transmission controller to control a first domain, comprising:
- a packet generator configured to generate a link discovery packet;
- a packet transmitter configured to transmit the link discovery packet to a first switch in the first domain;
- a packet receiver configured to receive, from the first switch, a response packet with respect to the link discovery packet;
- and
- a link manager configured to detect, based on the response packet, a link between the first switch and a second switch in a second domain,
- wherein the response packet is generated by a reception controller to control the second domain.
A reception controller to control a second domain, comprising:
- a packet receiver configured to receive a link discovery packet from a second switch in the second domain;
- a packet generator configured to generate a response packet with respect to the link discovery packet;
- and
- a packet transmitter configured to transmit the response packet to the second switch,
- wherein the link discovery packet is generated by a transmission controller to control a first domain in order to detect a link between the second switch and a first switch in the first domain.
A method of link discovery of a transmission controller to control a first domain, the method comprising:
- generating a link discovery packet;
- transmitting the link discovery packet to a first switch in the first domain;
- receiving, from the first switch, a response packet with respect to the link discovery packet generated by a reception controller to control a second domain;
- and
- detecting, based on the response packet, a link between the first switch and a second switch in the second domain.
