Supported Topologies
Regardless of the JungleMUX network topology used (point-to-point
ring), at a node where Ethernet access is required (and the choice is to use
ETHER-1000 unit rather than ETHER-10 or ETHER-100), one ETHER-1000 unit
and one paddleboard assembly are required.
(intermediate) node in a linear network, Ethernet traffic may be dropped from
either of both directions.
An ETHER-1000 unit is connected with one or more other ETHER-1000 units in
the same JungleMUX network to form a point-to-point, linear or ring ETHER-
1000 network topology. Ethernet ports of all ETHER-1000 units that make up
such a topology create an Ethernet switch with geographically spread access
ports (a "distributed Ethernet switch"). An example of ETHER-1000 ring network
topology is shown in Figure 4. The devices on the LAN segments connected to
ETHER-1000 unit paddleboards at all six sites can exchange traffic through
common bandwidth (N x STS-1 SPE).

A point-to-point topology may be considered a special case of a linear network. Two-node ring
topologies are sometimes confused with point-to-point networks. The main difference is the
number of fibers used between the two nodes (two vs. four).
