Point-to-Point (P2P) transport service

Point-to-Point (E-line in the MEF classification, hereinafter also referred to as the P2P service) is a transport service within involves establishing a connection between two service interfaces of CPE devices on top of an Ethernet network for efficient and secure communication without the use of intermediate network devices. This is especially relevant when using applications that must transmit information in real time or exchange large files.

When creating a P2P service, you must specify the service interface that sends traffic (hereinafter referred to as the source interface) and the service interface that receives traffic (hereinafter referred to as the destination interface).

Creating a P2P service

Before creating a P2P service, you must complete the following steps:

• Activate CPE devices.
• Create a constraint (Manual-TE or threshold).
• Create service interfaces.
• Create a traffic filter.
• Create a QoS rule.

To create a P2P transport service:

1. In the menu, go to the Infrastructure section.

   The SD-WAN infrastructure management page is displayed. By default, the Network resources tab is selected, which displays the table of SD-WAN Controllers.

2. Click Management next to the SD-WAN Controller and in the drop-down list, select Configuration menu.

   This opens the SD-WAN Controller configuration menu. By default, you are taken to the Controller nodes section, which displays a table of Controller nodes.

3. Go to the P2P services section.

   A table of P2P services is displayed.

4. In the upper part of the page, click + P2P service.
5. This opens a window; in that window, in the Name field, enter the name of the transport service.
6. In the Constraint drop-down list, select a previously created constraint that you want to add to the transport service.
7. In the Balancing mode drop-down list, select the balancing mode for evenly distributing traffic among the links to prevent congestion of individual links and prevent performance issues for users:
   • Per-flow — Balancing across flows (sessions). During transmission, flows are evenly distributed across the links. This is the default setting.
   • Per-packet — Per-packet balancing. During transmission, packets are distributed evenly across the links.
   • Broadcast — Packets are sent to all links simultaneously to prevent losses.
8. If necessary, in the Description field, enter a brief description of the P2P service.
9. In the Switch and Port drop-down lists on the left, select the CPE device and the service interface created on it that you want to use as the source interface.
10. In the Switch and Port drop-down lists on the right, select the CPE device and the service interface created on it that you want to use as the destination interface.
11. To display service interfaces that were previously added to transport services in the Port drop-down lists, select the Show used interfaces check box. This check box is cleared by default.
12. To swap the values selected in the Port drop-down list for the source interface and the destination interface, select the Switch interfaces check box. This check box is cleared by default.
13. If necessary, add a backup source interface through which traffic must be transmitted if the primary interface goes out of service:
    1. Select the Use backup interface check box. This check box is cleared by default.
    2. In the Backup switch and Backup port drop-down lists, select the CPE device and the service interface created on it that you want to use as the reserve service interface.
    3. To display service interfaces that were previously added to transport services in the Backup port drop-down list, select the Show used interfaces check box. This check box is cleared by default.

       If the primary service interface goes back online, the transport service continues to use the reserve service interface.

14. In the Inbound filter drop-down lists on the left and right, select the previously created traffic filter for the source and destination interfaces.
15. In the QoS drop-down list, select the previously created QoS rule for the source interface.
16. If you need to monitor the status of both service interfaces and when one of them becomes disabled, automatically disable the other, select the Propagate interface status check box. This check box is cleared by default. This check box cannot be selected when the Use backup interface check box is selected.

    When the service interface that was disabled first goes back online, the second service interface that was automatically disabled also resumes operation. This functionality works only if the Access encapsulation type is used on the service interfaces. The encapsulation type is selected when creating the service interface.

17. Click Create.

The P2P service is created and displayed in the table.
