3SCHEDULE OF WORK Beginning of the project – 1999. Operational requirements and conception – 1999/2000.„Testbed” – 2001/2002.Tactical and Technical Requirements – end of 2002.Technical documentation of devices and shelters – 2003.Prototypes of the shelters – 2004/2005.Testing and national certification – 2006.Implementation and developing 2006/2007.Before going into details I will give you the necessary background information.The work under development of the KOKUS project started in 1999.The first stage of realization of this project was development of operational and functional assumptions and conception of the system (from 1999 to 2000).Next, to verify the conception there has been built the laboratory model (testbed), which modelled basic elements described in system’s conception.From 2001 to 2002 on the basis of the testbed (with variable structure – some of the elements were bought, some of them only borrowed) there have been performed groups of experiments.
4TESTBEDThe current structure of the testbed is shown on this slide. There can be seen particular groups of equipment, like ATM switches, ISDN exchanges, IP routers and support equipment (hubs, terminals). The architecture of the testbed was being changed and acquired during the researches. The main tests included:Tests of efficiency of performing ATM services (using link simulators and real connections)Tests of accuracy of performing ISDN and IP servicesTests of cooperation of ATM and ISDN technologies, for example CES – connection’s emulation and other solutionsTests of cooperation of ATM and IP technologies (using particular protocols: CLIP, LANE and MPOA)Tests of cooperation with narrowband networks - DSTG interface (based on STANAG 4578)Video services’ performance – in different technologiesand other groups and subgroups of detailed tests devoted to solving different problems.
5Tactical Communications for the Land Combat Zone - Post-2000 OTHER PROJECTSTactical Communications for the Land Combat Zone - Post-2000(TACOMS Post-2000) - NATO nationsWarfighter Information Network (WIN-T) - USARITA-2000, ATTILA - FranceCormorant, Falcon UKTITAAN NetherlandsTASMUS TurkeyPolish idea of developing the prospective communication system is not unique.Similar projects have been also carried out in other countries.They are undoubtedly the source of very important information and new ideas that must be taken into consideration by our engineers.The crucial project is international TP2K – TACOMS Post 2000, which will lead to developing the family of standards on the interoperability of heterogeneous communication systems.
6ProgramTACOMS PostPoland is one of thirteen participants in this project. We perform a group of, so called, Work Packages.While performing KROKUS project we are trying to meet requirements specified in TACOMS and prepare for future implementation of the whole standard.
7TACOMS Post - 2000 Objective a. Design,b. Validate, andc. Establishcommon standards for a post generation of NATO tactical communications system.The objective of the TP2K is to design, validate and establish common standard for the interoperation of the communication systems of NATO participant countries. It is not to produce the actual system, but to develop a special kind of common language that can be used to interconnect systems built in different technologies.
8MAIN FEATURES OF THE SYSTEM - required level of interoperability (TP2K)- interworking with stationary communication systems- interoperability with existing systems- COTS principle- the latest technologies- advanced telecommunications services- management- security- open for modificationNow let’s have a look at the basic features of the system developed in Poland.First of all – it must provide the required level of interoperability with other systems (in terms of TP2K to be able to enable interworking with stationary communication systemsIt should base on commercial equipment COTS - Commercial Off The ShelfAnd use the newest technologies and services (with emphasis on necessity of providing QoS -Quality of Service)The system should also provide high degree of security of transferred information and modern system management methodsThe last but not least – it should be open for modifications and enable implementation of emerging new solutions.
9ISDN Ethernet ATM Technologies used in the system used in the trunk and access nodes. ISDN switches first of all should provide phone services for subscribers.used in local area network based on TCP/IP family protocols. This technology should provide data transmission in the system.used in the trunk and access nodes. ATM switches are the main elements of these nodes. Purpose - integration of different technologies used in nodes, provision of effective trunks’ utilization in the system and quality of service.ISDNEthernetATM

11SECURITY SUBSYSTEMSecurity subsystem will be realised according to “two-level encryption” rule. It will be:Bulk encryption – performed by bulk encryption equipment (in internodal relations)Source encryption – performed in ISDN terminals as well as in IP networks (by IP-Crypto) and in radio subsystem.

13Location of the shelters in the trunk node This slide presents exemplary location of the communication shelters in the WAS node.It is foreseen to use one switching shelter and three transmission shelters, which means realization of 12 radiorelay directions.WAS node can also include: RAP shelter, delegated narrowband transmission shelter, and mentioned earlier satellite terminal.The major part of the node will be the switching shelter.
14LAS nodeSATHC LOSHC LOSLOSZCVSD systemsDSTGATMSwitchE1, E2ZE1STM-1other(PCM)systemsE1STM-1ZE1The architecture of the communication node on command post (that is LAS node) is very similar to the architecture described earlier.There should be noticed however major differences:The switching access part is expanded (because of the big number of users)Equipment will have a different module structure – for example ATM switch will have smaller number of network ports and greater number of access ones. This is true also for ISDN exchanges and IP routers.The transmission part will be limited, since the LAS node is connected to Wide Area Subnetwork by only two radiorelay links.Router (IP)PBX(ISDN)SwitchLANEthernetLANdigital (ISDN)analogvideoSubscribers
15Location of the shelters in the access node This slide presents exemplary location of the communication shelters in the LAS node.As we can see it is foreseen to use one switching shelter and one transmission shelter, which means realization of maximum 3 radiorelay directions.LAS node may include also elements mentioned while describing WAS node, the narrowband transmission shelter and satellite terminal.
