    摘要: In communication method for communicating via a transmission channel to which first communication apparatuses communicating based on a first communication system, second communication apparatuses communicating based on a second communication system, and third communication apparatuses communicating based on a third communication system are connected, a data transmission domain and a notification domain for notifying a data transmission within the data transmission domain are allocated to the first communication apparatuses, the second communication apparatuses, and the third communication apparatuses, respectively. In the communication method, notices of the data transmission for each of the first communication apparatuses, the second communication apparatuses and the third communication apparatuses are transmitted within the notification domain, and the data transmission domain is reallocated in accordance with the notices transmitted from the first, second and third communication apparatuses.

    摘要: A method includes receiving, at a first distributed control system (DCS) node over a network, information associated with a security manager. The method also includes establishing multiple communication channels between the first DCS node and the security manager over the network using the information, where the communication channels include a non-secure channel and a secure channel. The method further includes receiving security credentials from the security manager at the first DCS node over the non-secure channel and receiving a security policy and an activation time from the security manager at the first DCS node over the secure channel. In addition, the method includes transitioning the first DCS node to communicate with a second DCS node over the network using the security policy at the activation time.

    摘要: A method includes receiving (304), at a first distributed control system (DCS) node (202) over a network, information associated with a security manager (208). The method also includes establishing (306, 310) multiple communication channels between the first DCS node and the security manager over the network using the information, where the communication channels include a non-secure channel and a secure channel. The method further includes receiving (308) security credentials from the security manager at the first DCS node over the non-secure channel and receiving (312) a security policy and an activation time from the security manager at the first DCS node over the secure channel. In addition, the method includes transitioning (316) the first DCS node to communicate with a second DCS node over the network using the security policy at the activation time.
