Abstract
Methods, systems and data structure for facilitating identification of nodes in a ring network are provided. According to one embodiment, a data structure is stored on a computer-readable storage media of a node (e.g., a blade) participating in a ring network, within a multi-blade system, for example. The data structure includes a packet-ring master field, a control-node master field, a node characteristics field, a connection state field, a node identification field and a marker field. The packet-ring master field indicates whether the node is a current packet-ring master. The control-node master field indicates whether the node is a control-node master. The node characteristics field specifies per-node characteristics. The connection state field indicates a current connection state of the node. The node identification field specifies the node. The marker field indicates whether the data structure is a node discovery marker.
