Traffic Shaping

Traffic Shaping allows administrators to control bandwidth usage and prioritise critical traffic.

Configuration

Enable Traffic Shaping: Enables or disables the traffic shaping engine.

WAN Capacity

WAN Download Throughput: Specifies the maximum download bandwidth available from the ISP.
LAN Download Throughput: Specifies the maximum upload bandwidth available to the ISP.

Dedicated VoIP Capacity

Enable VoIP dequeuing and prioritisation: VoIP traffic is prioritised above other traffic.
VoIP Bypass DPI Engine (Not Recommended): VoIP traffic bypasses the Deep Packet Inspection engine.
Note: Bypassing the DPI engine for voice traffic could allow for better quality VoIP calls, however traffic will not be accounted for or protected.
VoIP Download Throughput: Specifies the reserved download bandwidth for VoIP traffic.
VoIP Upload Throughput: Specifies the reserved upload bandwidth for VoIP traffic.

Queues / Allocation / Rules

Traffic shaping is achieved by:

Creating Download and Upload Queues.
Defining bandwidth limits and priorities.
Assigning traffic to queues using Traffic Allocation Rules.

Add Download Queue

Name: The descriptive name of the queue.

Rate: The guaranteed minimum bandwidth allocated to the queue.

Ceiling: The maximum bandwidth the queue is allowed to use. If bandwidth is available, the queue can use up to this limit.

Priority: Determines queue precedence during congestion.

Lower number = Higher priority
Higher number = Lower priority

Example: Priority 2 will be served before Priority 5.

SFQ: Stochastic Fairness Queuing prevents a single stream from being able to use the entire queue. Recommeneded for highly constrained WAN connections and requires fair sharing. (Not recommeded for low latency requirements).

Add Upload Queue

Name: The descriptive name of the queue.

Rate: The guaranteed minimum bandwidth allocated to the queue.

Ceiling: The maximum bandwidth the queue is allowed to use. If bandwidth is available, the queue can use up to this limit.

Priority: Determines queue precedence during congestion.

Lower number = Higher priority
Higher number = Lower priority

Example: Priority 2 will be served before Priority 5.

Default Queues

The default-download-queue and default-upload-queue handle all traffic that does not match a specific traffic allocation rule.

These queues ensure that unmatched traffic is still shaped and controlled.

Traffic Allocation Rules

Traffic Allocation Rules determine which traffic is assigned to which queue.

Rules are evaluated in order from top to bottom.

When traffic matches a rule’s criteria, it is assigned to the specified:

Download Queue
Upload Queue

Add Traffic Tagging Rule

URL Group

Rule Type: URL Group
URL Group: Select a URL Group created on the Policies page.
Download Queue: The Download Queue the rule will be applied to
Upload Queue: The Upload Queue the rule will be applied to

Blacklist

Rule Type: Blacklist
Blacklist: Select a Blacklist category
Download Queue: The Download Queue the rule will be applied to
Upload Queue: The Upload Queue the rule will be applied to

IP Rule

Rule Type: IP Rule
Inbound Interface: This option allows the rule to apply to traffic coming in through the selected interface (such as WAN, LAN, VLAN etc.).
Source: Specifies where the inbound traffic originates from:
- Any Source: Apply the rule to any source
- MAC Address: Apply the rule to a specified MAC address
- Identity: Apply the rule to identies
- Policy: Apply the rule to a policy created on the Policies page
- IP Address/Range: Apply the rule to an IP address or range
Destination: Specifies the destination for the traffic:
- Any Destination
- IP Address/Range
Protocol: Specifies which protocol (TCP, UDP, etc.) the rule will apply to. Setting this to Any Protocol means the rule is not restricted to a specific type of traffic, and will accept all protocols.
- TCP
- UDP
- GRE
Download Queue: The Download Queue the rule will be applied to
Upload Queue: The Upload Queue the rule will be applied to
