SD-WAN Observed Protocols Test

A particular application in the network can be defined by the group of rules that is applied to it. The SD-WAN configuration editor provides a default list of rule groups, and also lets you to create custom rule groups and tag individual rules to the application. Using the configuration editor, you can also create rules for traffic flow and associate the rules with applications and classes. You can specify criteria to filter traffic for a flow, and can apply general behavior, LAN to WAN behavior, WAN to LAN behavior, and packet inspection rules. It is important to monitor the LAN to WAN behavior, WAN to LAN behavior, and packet inspection rules periodically so that the any change in the WAN LAN behavior is identified instantly and preemptive measures taken accordingly. The SD-WAN Observed Protocols test helps administrators in taking these pre-emptive measures.

For each configured rule, this test reports the data/packet traffic between LAN to WAN and WAN to LAN. Using this test, administrators can figure out the rule that is most frequently used for LAN TO WAN data/packet transmission and vice versa.

Target of the test : A Citrix SD-WAN

Agent deploying the test : A remote agent

Outputs of the test : One set of results for the each Rule Group:Rule ID pair on the target appliance.

Configurable parameters for the test

Parameter	Description
Test Period	How often should the test be executed. By default, this is set to 5 minutes.
Host	The IP address of the target SD-WAN appliance for which this test is to be configured.
Port	Refers to the port at which the target SD-WAN listens to. By default, this will be NULL.
Timeout	Specify the time duration (in seconds) beyond which this test should time out in the Timeout text box. The default is 10 seconds.

Measurements made by the test

Measurement	Description	Measurement Unit	Interpretation
LAN to WAN data transmission	Indicates the amount of data transmitted over the LAN to WAN link for this rule during the last measurement period.	MB	An unusually high value of this measure may indicate a potential congestion or slowdown of traffic over the LAN to WAN link. It also indicates that you may have to reconfigure the appliance with more robust QoS policies to prevent such unpleasant eventualities.
LAN to WAN packet transmission	Indicates the number of packets transmitted over the LAN to WAN link for this rule during the last measurement period.	Packets
WAN to LAN data transmission	Indicates the amount of data transmitted over the WAN to LAN link for this rule during the last measurement period.	MB	A very high value of this measure may indicate a potential congestion or slowdown of traffic over the WAN to LAN link. It also indicates that you may have to reconfigure the appliance with more robust QoS policies to prevent such unpleasant eventualities.
WAN to LAN packet transmission	Indicates the number of packets transmitted over the WAN to LAN link based on this policy during the last measurement period.	Packets
