This wtanag is called Network Re-Initialization. Support of frequency hopping in the HF band is foreseen by the system but not yet supported by an implementation.
Legacy solutions would be technically possible but at the expense of lost interoperability. The 5522 of Link 22 uses a layered communications stack approach to produce an open system architecture, with well defined interfaces between the subcomponents.
In addition, Link 22 automates Congestion Management in a number of different ways. This protocol provides the unit with the most current parameters necessary to join the network.
When each unit is polled, it transmits its data without prioritizing the data, so no unit can be polled until the current transmitting unit completes its transmissions. It could even be implemented with the SPC being housed within the radio. Virtually all functions work in this manner called distributed protocolsso there is no single point of failure.
Views Read Edit View history. Link 22 requires each unit to initialize with the same fundamental parameters as all other units. Four levels of message perishability are provided by the system, and the TSR specifies which level applies to the data to be transmitted. This last resort reduces the congestion, but it also affects the delivery of messages.
If DTDMA does not achieve the desired result, the unit managing a NILE Network can change the configuration of the network to redistribute the available capacity, or change the parameters of the media in use in an attempt to increase the network’s capacity. The result is that it is significantly easier to plan and operate than either Link 11 or Link The System Network Controller SNC calculates whether the relay is necessary, based on its knowledge of the connectivity among units.
For both of these services, there are five types of addressing available.
The equipment needs to be housed in suitable enclosures appropriate to the environment in which the equipment is to be installed. Please help improve this article by adding citations to reliable sources.
No cleanup reason has been specified. Among other stana, the selection of messages for transmission is based on the priority and the QoS of each message, which provides better use of available resources based on the operational situation.
Link 22 complements Link 16 by providing additional bandwidth in other frequency ranges and in particular by providing the BLOS and automatic relay capabilities. This is an open issue. The SNC software requires a computer processor to execute satnag code. A unit cannot transmit until it is polled. Logistics spares would also need to be acquired to provide an adequate level of cover in case of unit failure. It is possible to distribute encrypted keys as PC files, in which case a special serial cable would be required to load stannag file from a PC into the DTD.
Sanag 22 provides a number of Quality of Service QoS features, which are specified with each transmission request. Each unit that performs a special role is required to designate a Standby unit, which can automatically take over the role in case of failure.
Two different Addressing services are provided, with and without Acknowledgement, which can usually be used at the same time.
The NCT is the number of minislots that form the network cycle sum of the length of all timeslots. This ensures that each unit has an opportunity to transmit at least once within a given period of time, called the Network Cycle Time NCT. Uses TDMA which provides deterministic access to the network. Greater coverage is provided by the automatic relay of messages within the Link 22 system as previously mentioned.
The FJ messages encapsulate Link 16 J-Series messages within Link 22 messages, enabling Link 16 tactical messages to be transmitted without modification within Link The TDS may also require an accurate time to guarantee synchronization among all the subsystems.
These parameters are specified in the OLM. The DLP can perform minimal tactical message processing, or it can be a complete multilink Command and Control C2 system. A cyclical period of time is divided up into timeslotswhich can be of different durations. Two Ethernet ports can be joined together with a simple cross-over Ethernet cable point-to-pointor joined together using an Ethernet hub or switch.
Link 22 needs to be supplied with coordinated universal time UTC which, if not already available on the platform, must be acquired. The Link 22 system ensures that this Data Originator Identification is delivered along with the data, so that any unit receiving it knows staang unit originated the data regardless of its route through the system. Each listed item will be discussed further. Learn how and when 552 remove these template messages. The tactical messages were discussed in Chapter 2 Section D.
