Tunnels Summary
Monitoring > Tunnel Health > Other Tunnel Statistics > Tunnels Summary
This tab summarizes tunnel statistics, including reduction, throughput, jitter, latency, and packet loss. For each Business Intent Overlay, the specified Link Bonding Policy determines the bandwidth efficiency. The data counts and trannsmission rates can be influenced by the policies you deploy. To guarantee service quality levels, High Availability requires the most overhead and High Efficiency requires the least. The table shows the total bandwidth used. The Payload filter removes overhead from the displayed values. The values reported are for the time period you specify.
The Tunnels Summary screen includes the columns listed in the table below.
Column | What is Reported | Comments |
---|---|---|
Tunnel | A logical connection established between two endpoints over a physical network infrastructure. | You can dynamically select the best path for data transmission based on real-time network conditions. Tunnels can be rerouted as needed to maintain optimal performance and reliability or can be configured to prioritize certain types of traffic. |
Status | Indicates whether the tunnel is active (up) or inactive (down). | An active status means the tunnel is successfully established and can transmit data. An inactive status indicates a failure or disconnection. |
<– LAN (inbound) | Amount of data transmitted to the LAN (post-WAN de-encapsulation). | Reports the amount of post-WAN de-encapsulated data transmitted through the tunnel from the WAN to the LAN. |
<– WAN (inbound) | Amount of data received from the WAN (pre-WAN de-encapsulation). | Reports the amount of pre-WAN de-encapsulated data recieved through the tunnel from the WAN. |
<– Reduction % (inbound) | Total traffic reduction for inbound traffic on this tunnel. | The calculation is as follows: Reduction % for inbound traffic = 100 (Received from LAN – Transmitted to WAN) / Received from LAN. |
<– LAN Throughput (inbound) | Inbound WAN to LAN Traffic Rate Kbps (post-WAN de-encapsulation). | Reports the post-WAN de-encapsulated data transmission rate to the LAN. |
<– WAN Throughput (inbound) | Inbound WAN Traffic Rate Kbps (pre-WAN de-encapsulation). | Reports the pre-WAN de-encapsulated data transmission rate through the tunnel. |
LAN –> (outbound) | Amount of Data Transmitted from the LAN to the WAN (pre-LAN encapsulation). | Reports the amount of pre-LAN encapsulated data transmitted to the WAN tunnel from the LAN. |
WAN –> (outbound) | Amount of Data Transmitted to the WAN (post-WAN encapsulation). | Reports the amount of post-WAN encapsulated data transmitted through the WAN tunnel. The policies you deploy can effect this amount. |
Reduction % –> (outbound) | Total traffic reduction for outbound traffic on this tunnel. | The calculation is as follows: Reduction % for outbound traffic = 100 (Received from LAN – Transmitted to WAN) / Received from LAN. The Reduction % shows the effect of the policies you deploy. |
LAN Throughput –> (outbound) | Outbound LAN Traffic Rate Kbps (pre-LAN encapsulation). | Reports the amount of pre-LAN encapsulated data transmitted to the WAN tunnel from the LAN. |
WAN Throughput –> (outbound) | Outbound WAN Traffic Rate Kbps (post-WAN encapsulation). | Reports the post-WAN encapsulated data transmission rate (kbits/second) through the tunnel. |
Loss(packets) | The percentage of packets that are lost during transmission through the tunnel. | High packet loss can severely impact application performance and reliability. |
Max Loss(packets) | The maximum number of packets that are lost during transmission through the tunnel. | Transient high packet loss can cause sporadic application performance and reliability issues. |
Avg Jitter (ms) | The average variation in packet arrival times. | High jitter can affect the quality of real-time applications, leading to issues like voice call distortion or video lag. |
Max Jitter (ms) | The maximum variation in packet arrival times. | Transient high jitter can cause sporadic degredation in the quality of real-time applications, leading to issues like sporadic voice call distortion or video lag. |
Latency (ms) | Reports the average time it took for a data packet to travel from one end of the tunnel to the other. | Low latency is crucial for real-time applications such as voice and video communications. |
Max Latency (ms) | Reports the maximum time it took for a data packet to travel from one end of the tunnel to the other. | Transient high latency can cause sporadic degredation of real-time applications such as voice and video communications. |
