The term CCS network denotes the function network of two processors between which a CCS connection is set up.
Passwords can be allocated for the local and the partner processor which must be specified when a CCS connection is set up. Before a CCS network can be created, the local and the partner processor must know both passwords (see section “Establishing connections” and section “Clearing down connections”). This minimizes the risk for each processor of linking up with an illegal partner.
The CCS network mainly acquires practical value when it becomes part of the shared pubset or XCS network (a CCS network always consists of two processors; a shared pubset or XCS network, on the other hand, comprises up to 16 processors. The (CCS) connections necessary for this kind of network are set up between two processors at a time, i.e. a shared pubset network consisting of five processors has at least 4 CCS networks).
A CCS network can also be used to monitor partners without the aid of shared pubsets.
Connection, partner type
The CCS network is only handled via CCS connections and a partner can be a CCS or an XCS partner.
Connection monitoring
The two processors monitor the CCS connection (and thus also the relevant partner) independently of each other by periodically sending special messages which the partner must reply to within a certain time. In the event of failure or lost connection, a connection recovery action is implemented to restore the connection (and thus also the network) to normal functioning.
In this context, see also section “Failure of BCAM connections”.
Applications (functions)
As a rule, the CCS network is part of a shared pubset or XCS network. As an independent network, the CCS network possesses the functionality of the LCS network and can additionally be used for partner monitoring. In addition the software monitor openSM2 is also supported.
