Mesh Network Overview

The AOS-W Instant secure enterprise mesh solution is an effective way to expand network coverage for outdoor and

indoor enterprise environments without any wires. As traffic traverses across mesh OAW-IAPs, the mesh network

automatically reconfigures around broken or blocked paths. This self-healing feature provides increased reliability

and redundancy and allows the network to continue operation even when an OAW-IAP stops functioning or if a

connection fails.

Mesh OAW-IAPs

Mesh network requires at least one valid uplink (wired or 3G) connection. Any provisioned OAW-IAP that has a valid

uplink (wired or 3G) functions as a mesh portal, and the OAW-IAP without an Ethernet link functions as a mesh

point. The mesh portal can also act as a Virtual Controller. A Mesh portal (MPP) uses its uplink connection to reach

the switch, a mesh point, or establishes an all wireless path to the mesh portal. Mesh portals and mesh points are

also known as mesh nodes, a generic term used to describe OAW-IAPs configured for mesh.

If two OAW-IAPs have valid uplink connections, there is redundancy in the mesh network, and most mesh points try

to mesh directly with one of the two portals. However, depending on the actual deployment and RF environment,

some mesh points may mesh through other intermediate mesh points.

In an AOS-W Instant mesh network, the maximum hop count is two nodes (point >point >portal) and the maximum

number of mesh points per mesh portal is eight.

Mesh OAW-IAPs detect the environment when they boot up, locate and associate with their nearest neighbor, to

determine the best path to the mesh portal.

AOS-W Instant mesh functionality is supported only on dual radio OAW-IAPs only. On dual-radio OAW-IAPs, the 5

GHz radio is always used for both mesh-backhaul and client traffic, while the 2.4 GHz radio is always used for client

traffic.

Mesh service is automatically enabled on 802.11a band for dual-radio OAW-IAP only, and this is not configurable.

The mesh network must be provisioned for the first time by plugging into the wired network. After that, mesh works

on OAW-IAP-ROWs like any other regulatory domain.

Mesh Portals

A mesh portal (MPP) is a gateway between the wireless mesh network and the enterprise wired LAN. The mesh

roles are automatically assigned based on the OAW-IAP configuration. A mesh network could have multiple mesh

portals to support redundant mesh paths (mesh links between neighboring mesh points that establish the best path

to the mesh portal) from the wireless mesh network to the wired LAN.

The mesh portal broadcasts a mesh services set identifier (MSSID/ mesh cluster name) to advertise the mesh

network service to other mesh points in that AOS-W Instant network. This is not configurable and is transparent to

the user. The mesh points authenticate to the mesh portal and establish a link that is secured using Advanced

Encryption Standard (AES) encryption.
