JCSS STANDARD MILITARY MODELS
JCSS is based on OPNET Modeler and includes all standard OPNET COTS Models and Protocols. The models listed below are a subset of the overall model library. Please refer to the Model Userguide for additional information.
JCSS features a wide variety of IP network devices that can be configured to evaluate network and traffic performance. IP devices from Cisco and Juniper Networks for example can be deployed to route IP traffic and to conduct network convergence, capacity planning, and other types of network connectivity studies. JCSS supports all standard IPv4 and IPv6 standard routing protocols. (
Ex: Cisco 7600s, Juniper MX480, Cisco 3000s, Juniper ERXs)
JCSS ATM models including Foundry FastIron family of devices, Marconi offer ATM switching, ATM QoS Priority Scheme, and Port Buffer Configuration.
(Ex: Marcons_ASX1000, FoundryNetIron, CISCO_LS_1010)
The PSTN Voice model suite provides the ability to model real-world end devices (phones), routers/switches, gateways, and other special voice elements.
(Ex: DNVT, LEN, NCS, DSS1-3, REDCOM IGX, SEN, SMU, TTC-39, TTC-49, MCU)
WAN Performance Improvement Devices:
JCSS provides support for several devices that can be used to optimize WAN performance. Some of the models include:
Featuring both the
Riverbed Steelhead Appliance
users can study impact of Caching, TCP Acceleration, Packet Compression and Data De-duplication which all reduces the amount of data that travels across the WAN and improves the speed of data. The Riverbed model has been enhanced to allow the pre-population of application data in the model at simulation start time, ensuring that even the initial application request will result in reduced data transmission over the WAN links.
The QoS Edge Device (QED) is a model that utilizes the Measurement-based Approach to Call Admission Control, referred to as the
. The QED device measures detailed per-packet statistics and uses these statistics to interpret network congestion, to make call admission and preemption decisions based on continuous congestion measurements.
A Performance Enhancing Proxy (PEP) device serves as a WAN accelerator for TCP, performing TCP Acceleration Open and other TCP optimization techniques to improve the performance of TCP over high latency WAN connections.
JCSS offers a variety of crypto models including KGs, KIVs and HAIPEs. These encryption devices can affect connectivity and performance by preventing non-secure traffic from accessing the secure network and adding encryption overhead on traffic traveling between encrypted enclaves.
HAIPES provide Layer 3 encryption support while allowing secure enclaves to discover and advertise remote enclaves to the local network.
In addition to the ability to configure Peer Enclave and Local Enclave Prefix Tables (PEPTs and LEPTs), JCSS introduces BGP Peer Discovery, allowing HAIPE host servers to share PEPT and LEPT data utilizing BGP to manage the data between servers. HAIPE connections can be predefined manually, or set up via the PEPT/LEPT table information contained in HAIPE host servers.
Tactical Radio Devices:
The JCSS model library includes a wide variety of DoD tactical radio models that include the following:
PRC Radio Family:
JCSS includes PRC Radios, such as the
models that utilize the MIL-STD-188-220 for modeling the PRC radio Network Access Delay (NAD) scheme and support Frequency hopping
The Enhanced Position Location Reporting System (EPLRS) model suite offers support for
CSMA, HDR, MSG
needlines, allowing users to customize EPLRS Network Managers (ENMs) to dictate Needline configuration and time slot block assignment
Developed by SPAWAR Systems Center, San Diego, the Link-16 suite of devices from the Tactical Data Link (TADIL) family are designed to support real-time tactical data between units within military operations. JCSS offers
devices with customizable Time Slot Blocks (TSBs) and Network Participation Groups (NPGs), allowing users to create Link-16 networks and determine if any TSB conflicts, data reservation and NPG connectivity issues occur as a result of network configuration or mobility
The Combat Service Support Automated Information Systems Interface (CAISI) was added into JCSS 12.0. The CAISI model performs Access Point, Ethernet switching and long range wireless mesh functionality to allow for multiple wireless connections between multiple tactical units on the field.
JTRS Radio Family:
waveform models are supported in JCSS. Please note that waveforms are not shipped with the software and must be requested through the website. In addition, JCSS provides a
Waveform Translation Gateway
model to allow communication between the JTRS waveforms and among legacy waveform models including UHF DAMA, Link-16, PRC and EPLRS networks.
Allowing for near Ethernet connection speeds in a point-to-point or point-to-multipoint network configuration, the Harris 7800w radio models support VLAN configurations over the wireless devices as well as Adaptive Modulation that responds to the condition of the network connection between Harris devices
STD, ABE, Discovery and Network CDLs are supported in JCSS, allowing for mobile air-to-ground communication, including dynamic connection formation between networks utilizing D-CDL to create ABE-CDL network connections, N-CDL slot allocation tracking and Adaptive Modulation.
JCSS has Smartphone models available for deployment that support UMTS, LTE, WiMAX, Wireless 802.11 and TDMA communications. By configuring and modifying the technology priority list of a Smartphone, users can observe Smartphones switch between technologies during simulation execution to observe performance impacts as a result of network swaps.
Highband Network Radio (HNR):
Contributed by Harris Corporation, the HNR models have been integrated into the JCSS software. Users are now able to deploy and configure HNR networks and can use the HNR Model User Guide as reference. However, due to the proprietary information, model code access has been restricted and users will not be able to view or modify the HNR source code.
