best effort traffic. User Priority allows a user to request that traffic to/from a node be given
preferential treatment. The resulting priority order is reflective of queuing order.
Quality of Service
The primary objective for QoS is to provide the capability of differentiating traffic classes. The
QoS provision will be implemented on a per-hop basis without explicit end-to-end QoS
management.
Three main QoS functionalities have been implemented:
1) Packet classification
2) Prioritized channel access
3) Priority queue management with rate limiting
User Priority
The User Priority service can be provisioned per-node for use with tiered service and
emergency access systems. This priority feature is unique to the MEA network and only exists
between endpoints within the MEA network or between a MEA network node and the
ingress/egress node on the MEA network.
Nodes outside of the MEA Core LAN cannot request a particular priority for transmitted or
received traffic. Any traffic into the MEA network needing prioritization must be prioritized at the
ingress access point or router. Any traffic out of the MEA network will lose its priority
assignment at the egress.
MEA wireless traffic will carry priorities attached to each packet. The MeshAPI can be used to
tune the default priority of the local node
There is also an optional Emergency mode for use by special applications. The priority for use
in emergency mode is separately provisioned and must be explicitly enabled per node by the
network operator.
