The modern network-centric warfare relies on the Internet Protocol to provide data routing capabilities across the battlespace and across the world. Appian is an IPv4 multicast router for embedded tactical environments and supports Ethernet, PPP, and MIL-STD-188-220 (SINCGARS) interfaces.


A network is only as secure as its weakest link. Appian supports the full range of Internet security protocols including PAP, CHAP, SNMP v3, and Access Control Lists (ACLs). Passwords protect both SNMP and maintenance access.


We know that interoperability is the key to successful network communications. That's why Appian supports a wide range of communication standards based on the Net-2 TCP/IP stack.


Packaged for JTRS environments, Appian provides the complete Internet Controller (INC) Outstation capability in a modular, SCA-compliant deployment.
