31.2.4 Network Topology

CAN network topology is bus based. Replicated busses are not referred in CAN standard; however, it is

possible

to imp

lement

the

m

[39

,41].

Over

the

years,

some

star

topologies

for

CAN

have

been

proposed

[5,26,38].

e

solution

presented

in

[26]

is

based

on

a

passive

star

network

topology

and

relies

on

the

use

of

a

central

element,

the

star

coupler,

to

concentrate

all

the

incoming

signals.

e

result

of

this

coupling

is

then

broadcast

to

the

nodes.

e

solution

presented

by

Rucks

[38]

is

based

on

an

active

star

coupler

capable

of

receiving

the
