Subnets

A node announces subnets to the rest of the network so traffic for network equipment (like clients' computers) connected (wirelessly or directly) to the node can be routed from the network to the node for it to pass the traffic to equipment in question.

Subnet status key:

ok
the allocated/registered subnet is announced properly by the node
peering
the subnet is being announced as a result of a peering to some external network
not announced
the subnet has been allocated/registered but is not announced by the node
not allocated
the subnet is announced by the node but has not been allocated/registered
collision
the subnet is announced by the node and is causing a collision with allocated/registered subnet of another node

Immediate Neighbours (Peers)

Each node can have multiple immediate neighbours (peers) to which it is connected with different link qualities.

Node LQ ILQ ETX
tbilisijska-118 (10.254.140.129) 1.0 1.0 1.0

Columns:

Node
the node and its primary IP address
LQ
the ratio of packets that are successfully received from the node's neighbour
ILQ
the ratio of packets that are successfully sent from the node to its neighbour
ETX
measure of the link quality calculated from LQ and ILQ and used for routing decisions; closer to 1.0 is better

Connected Clients
A more detailed global list of currently connected clients is also available.

Traffic - eth0
This graph represents traffic of the node's ethernet interface.

Traffic - tap0
This graph represents traffic of the node's Internet uplink.

Traffic - wl0
This graph represents traffic of the node's wireless interface.

WiFi Signal/Noise
This graph represents received signal and noise on the node's wireless interface.

WiFi Signal/Noise Ratio
This graph represents signal-to-noise ratio of the node's wireless interface.
Higher it is, better the transmission over the interface can be.

WiFi Bitrate
This graph represents bitrate of the node's wireless interface. It is an upper limit of real (transmission) bitrate (in practice lowered by noise and protocol(s) overhead).

Routing Peers
Each node can have multiple immediate neighbours (peers) to which it is connected
with different link quality. This graph represents the number of the node's peers.
To evaluate peer connectivity check the individual Link Quality graphs.

Packet Loss
Packet loss is measured from a central location and does not indicate connectivity quality to neighbouring nodes. To evaluate immediate neighbour (peer) connectivity check the individual Link Quality graphs. The graph does correlate with packet loss on the connection to/from the Internet.

Average Link Quality, Link Quality to replicator (10.254.0.1), Link Quality to tbilisijska-118 (10.254.140.129)
Display:
  • LQ – the ratio of packets that are successfully received from the node's neighbour
  • ILQ – the ratio of packets that are successfully sent from the node to it's neighbour

Average ETX, ETX to replicator (10.254.0.1), ETX to tbilisijska-118 (10.254.140.129)
Display:
  • ETX – measure of the link quality calculated from LQ and ILQ and used for
    routing decisions; closer to 1.0 is better

Latency
Latency is measured from a central location and does not indicate latency to neighbouring nodes.
The graph does correlate with latency on the connection to/from the Internet.

Load Average
This graph represents the node's CPU load.

Memory Usage
This graph represents various types of node's free memory.

Number of Processes
This graph represents the number of node's processes.
