Aplas
billing
system
-­‐
software
for
ISPs
Corporate
product
Project
Description:
The
billing
system
for
Internet
Service
Providers
offers
full
control
over
customers`
IP
traffic,
provides
QoS(WFQ+,
IP
VLANs,
etc.),
firewalling
and
powerful
detailed
statistics.
Consists
of
the
routing
module(trafX),
billing
system
back-­‐end(with
proprietary
RADIUS
server,
DB
API,
etc.)
and
front-­‐end
with
multi-­‐language
support,
build
99%
in
JavaScript.
TrafX
is
the
low-­‐level
“slave”
module
written
entirely
in
C,
that
performs
IP
traffic
manipulation
and
gathers
statistic.
One
part
of
it
works
in
the
kernel
environment
in
a
form
of
the
FreeBSD
kernel
module.
Sophisticated
know-­‐how
algorithms
makes
it
extremely
efficient
for
broadband
channels.
Another
it’s
part
is
a
user-­‐level
extension
that
maintains
exchange
of
the
information
between
in-­‐kernel
trafX
part
and
the
remote
billing
server
over
network
connection.
Written
in
C++.
Also
there
is
a
command
line
tool
for
controlling
trafX
from
the
console,
SSH
for
example.
The
billing
system
back-­‐end
is
the
“brain”
of
the
entire
billing
system.
It
is
written
in
C++.
Has
modular
structure
with
embedded
RADIUS
server,
which
is
responsible
for
authenticating
users
who
work
over
VPN,
as
well
as
granting
to
them
privileges.
Thanks
to
the
state-­‐of-­‐art
database
synchronization
API
and
know-­‐how
sync
algorithm,
it
reacts
immediately
to
any
change
in
the
DB
within
5
seconds.
It’s
low-­‐level
C++
networking
API
takes
care
for
sending
instructions
to
every
“slave”
trafX
router,
as
well
as
for
receiving
statistic
from
them.
Statistic
is
being
then
analyzed,
and
moved
to
the
db.
The
back-­‐end
system
is
complete
multithreaded
system
designed
to
work
under
extremely
heavy
loads.
The
front-­‐end
consists
of
two
parts:
administrator
dashboard
and
user
panel.
The
admin
panel
is
a
modular
windows©-­‐like
system
written
99%
in
JS/AJAX,
with
extra
levels
of
security
and
efficient
data
exchange.
Has
multi-­‐language
support
with
dynamic
on-­‐fly
translation
with
a
single
click.
(no
reload
needed,
know-­‐how)
The
second
part
of
the
front-­‐end
is
a
user
panel,
i.e.
page
where
every
user
can
see
it’s
statistic
and
expenses
for
the
received
service.
Multi-­‐language
support.
Conclusion.
The
system
is
software
“monster”,
which
utilizes
big
number
of
technologies
and
techniques,
including
completely
unique
ones.
It
has
been
developing
over
almost
5
years,
and
unfortunately
didn’t
see
the
real
world
for
the
lack
of
financing.
However
it
is
still
functioning
in
the
closed
environment
on
the
testing
platform.
The
current
state
of
the
project
–
FROZEN.
