6. Market Need for Critical
Communications
• Military, PPDR (public protection and disaster relief) & CIP
(critical infrastructure protection [e.g. energy supply]) actors
have similar needs for communications
• In many connections (e.g. PSCE conference 7-8 June 2011),
common secure network for MIL, PPDR & CIP is needed
• TETRA/TETRAPOL based voice
• LTE based data (operational from 2020’s, common European
wide frequency allocation needed)
• Roaming is essential
• cross-border PPDR operations,
• multinational CI; power (electricity, gas) networks and
companies

7. Important topics when
considering PSC
1(2)
1. Technical reliability and trustworthiness
The communication must be safe and ”unbreakable”
2. Considering the long time investment
Solutions must withstand time as technology constantly evolves
3. ”Special circumstances” may occur at any time
The telecom operator may not ALWAYS be there?

considering PSC
2(2)
4. Co-operation between different actors
Users may have different ”statuses” and ICT-policies. For
example: Government vs. Civilian as in Army, Public Safety and
Industry – yet users may need to interact on the same
communications platform. Solutions should support, not
suppress, co-operation
5. Freedom of choice
The customer should be the ”master” of his application, not the
telecom operator or vendor
6. Special situations
Communication solutions should allow Ad-hoq users in a safe
way – Safety and Reliability first

10. Multichannel communication
is the ability to communicate over multiple physical connections
simultaneously and in parallel so that all communication links appear
like a single uninterruptable and robust link
People can do this (if they want)
IP: x.y.z.q
Computers can’t generally do this
even if “they would want to”
IP: q.w.e.r
The IP protocol used for data transfer can not bind a socket over two
or more physical connections simultaneously

11. How Multi-modems work
Each modem will get its own ip-address
from their operators
At this point, the ”control room” application
will see connection attempts fom 3
different IP-addresses

application

ADSL
The ”control
room” application
A ”multimodem” system cannot share communication between different
physical media without re-writing the application program to do so.
The reason is: TCP/IP does not support multichannel communication!
Re-writing an application to support multichannel communication is practially
very difficult in most cases.
Presenter: Paresh Rathod

12. Multi-channel communication
All the separate IP-addresses should ”merge”.
NO changes to the application should need to be done!

The structure should make the applications ”to believe” that they are
communicating over a single connection, however, the communication is
spread over multiple physical connections which may be IP or non-IP based!
The possibility of combining multiple communication channels into a single
enables regular telecommunication to be used in mission critical systems –
the demand for secure communication is huge and ever increasing!
Presenter: Paresh Rathod

13. Multichannel communication is:
Parallel use of data links regardless of technology
All the multiple parallel communication paths must appear as a SINGLE
uninterruptable communications channel

14. Reasons for developing a
new protocol
1.
Cyber warfare IS REALITY – Viruses, Denial of Service attacks etc.
2.
The IP protocol can’t do multichanneling and
multichanneling VPN’s do NOT solve the problem
3.
More and more applications use IP-protocol for transfer
4.
Machines and Software are not compatible
5.
Mixing teleoperators and the application can be problematic
6.
Taking future protocols into account: IP v4, IP v6 and others

16. DSiP Consists of two types ofstart, they Nodes and Routers make
When the nodes and routers software; interconnect. Routers
Nodes are the interface points in a DSiP routing network
neighbour connections and nodes connect to one or more router
All connections
are authenticated

nodes actively maintain the connections – if a connection breaks,
others will automatically form.

36. Benefits
In many connections
(e.g. PSCE conference 78 June 2011), common
secure network for
MIL, PPDR & CIP is
needed.
Separate networks
are wasting of
resources!

37. Future work
To solve
1. mission critical voice roaming in cross-border
operations
•
TETRA push-to-talk (PTT) services over LTE
2. secure PPDR & CIP (data) communication
challenges before 2020’s, when LTE based
systems might be operable.
• Use case:
• Secure communications for multinational electricity supply
• Mobile field command center for PPDR field operations
