Configuring Packet Redundancy for Circuits (CTPView)
The packet protector feature transmits one-for-one
duplicate packets into the IP network, which enables a possible recovery
scenario in the event of lost IP packets caused by transmission errors.
You can configure this feature on CTP, SAToP, and CESoPSN bundles.
Before you begin:
- Log in to the CTPView software at least at the Net_Admin
level.
- Connect the CTPView server to the CTP device for which
you want to configure this feature.
To configure packet redundancy using CTPView:
- In the side pane, select Bundle > Configuration.
- Run your mouse over the Display and
Select an Existing Bundle bar.
- In the table of bundles, select the bundle that
you want to modify.
- Under Bundle Options, place a check mark in the Advanced Options show check box to display
advanced parameters, and configure the parameters described in Table 1.
- Click Click to Submit Bundle AND Port
Changes.
Table 1: Packet Redundancy Parameter
Settings in CTPView
Field | Function | Your Action |
---|
Packet Protector | Specifies whether the CTP device sends and/or receives
cloned (duplicated packets). This option is useful in networks where you expect significant
IP packet loss. You need to configure the packet protector so that the setting
at one end of the bundle corresponds with the setting at the other
end of the bundle. For example, if you configure the local bundle to send cloned
packets to the network, configure the remote bundle to expect cloned
packets from the network. | Select: - Disabled—The CTP device does not send cloned packets
over the IP network, and it ignores cloned packets that it receives.
- Send cloned pkts to NET—The CTP device sends duplicated
packets over the IP network.
- Expect cloned pkts from NET—The CTP device uses
cloned packets that it receives when the IP network drops the original
packet. If the device receives both the original and cloned packets,
it ignores the cloned packet.
- Send & expect cloned pkts—The CTP device sends
duplicated packets over the IP network. The CTP device uses cloned
packets that it receives when the IP network drops the original packet.
- Send delayed cloned packets to NET—The CTP device
sends duplicated packets after the interpacket delay of the circuit.
- Send delayed & expect cloned packets—The CTP
device sends duplicated packets after the interpacket delay of the
circuit. The CTP device uses cloned packets that it receives when
the IP network drops the original packet.
- Expect cloned XOR packets—The CTP device uses cloned
XOR packets that it receives when the IP network drops the original
packet to regenerate the missing packet. If the device receives both
the original and cloned XOR packets, it ignores the cloned packet.
- Send & expect cloned XOR packets—The CTP device
sends duplicated XOR packets over the IP network. The CTP device uses
cloned XOR packets that it receives to regenerate missing packets
when the IP network drops the original packet.
