HiProvision - CSM Connection Scenarios
There are multiple connection scenarios possible between the HiProvision PC and the CSM (or
Dragon PTN network).
Direct connection;
Connection via switch, router;
Connection with CSM Redundancy;
Connection with HiProvision Redundancy;
Connection with Entry Point Redundancy.
Depending on the connection scenario, the configuration differs and IP addresses must be
configured in different places. All these connection scenarios are described in detail in Ref.
[2Mgt] in Table 2. In this manual, verify following chapters:
HiProvision: Discover and Approve the Dragon PTN Network Topology (DCN);
HiProvision Connectivity Redundancy: Use Cases.
c.
IP Address
The IP address of this management port (= CSM Front IP Address) can be changed via
HiProvision, see Ref. [2Mgt] in Table 2. How to set up the IP address on the HiProvision PC,
see also Ref. [2Mgt].
CAUTION: When changing IP addresses or IP ranges:
- Make sure that the Device IP Range of your network does not conflict with the CSM
Front IP Addresses of your entry points for this network. All these IP addresses and
ranges can be verified in the Entry Point(s) in the Discovery Tile in HiProvision.
- Make sure that the CSM Front IP address of each node only belongs to its own unique
subnet. Therefor each node must be configured in a different subnet.
- Redundant CSMs can be configured in the same subnet. If they are configured in a
different subnet, make sure each subnet is unique network wide.
2.2
Functional Operation
2.2.1
Exchange Data with the Outside World
The node exchanges services data (Ethernet, MPLS-
TP, E1/T1, SHDSL, C37.94, Serial data…)
with the outside world via the IFMs that are plugged into the Dragon PTN node. This means
that a Dragon PTN node communicates with other Dragon PTN nodes via its IFMs, not via the
CSM. The only data to enter/leave the front panel of the CSM is the management data
exchanged with HiProvision.
2.2.2
I/O with NSM, PSUs, IFMs and Dragon PTN Network
The active CSM processes status & control data between the NSM, PSUs, IFMs, backup CSM
and the Dragon PTN network via the node's backplane. The active CSM communicates this and
its own status & control data to HiProvision.
Furthermore, the active CSM controls the flow of user data by switching MPLS-TP packets
between the Dragon PTN network and the IFMs in its node. The IFMs are connected to the
active CSM in a star configuration resulting in an individual data bus for each IFM. Data
transfer is full duplex. See also §2.2.3.
