## Description

**VIRTUAL PROPOSERS DAY Q&A SESSION:** The Defense Advanced Research Projects Agency (DARPA) will host a Virtual Proposers Day question and answer (Q&A) session in support of PS-25-14, FLexible networking Using Intelligent Dialecting (FLUID) program on April 8, 2025, on Microsoft Teams from 1:00 to 2:30 pm Eastern Time (ET). The purpose of this virtual session is to provide possible FLUID proposers a forum to ask questions on the FLUID program. The Proposers Day Q&A session will be held at the Controlled Unclassified Information (CUI) level.

**PROGRAM OBJECTIVE AND DESCRIPTION:** The goal of the FLUID program is to enable Command, Control, Computing, Communications, Cyber, Intelligence, Surveillance, Reconnaissance and Targeting (C5ISRT) systems to operate under Degraded, Disrupted, Intermittent, and Limited (DDIL) network conditions.

The specific objective of FLUID is to reduce the load (consumed communication capacity) of a C5ISRT system (applications and network services), without sacrificing the overall system utility, so it can continue to operate under extreme capacity degradation: up to 30dB (i.e., 3 orders of magnitude) degradation compared to normal conditions. The FLUID program consists of a single Technical Area, divided into Phase 1A and Phase 1B.
