Armed Forces Network (AFN) signals via Transport Steams over Internet Protocol (TSoIP) on commercial internet using the Secure Reliable Transport (SRT)

            The US Army Regional Correctional Facility-Europe is exploring options for Contractor performance regarding the recommended equipment list for reception of Armed Forces Network (AFN) signals via Transport Steams over Internet Protocol (TSoIP) on commercial internet using the Secure Reliable Transport (SRT) protocol.

            Transition to SRT has been recommended for all last-mile distributors (LMDs) worldwide as AFN’s strategic modernization efforts include the abandonment of satellite delivery for AFN content. All SRT decoders provisioned to acquire and distribute AFN signals must be compatible with Multi-Program Transport Streams (MPTS) or Single Program Transport Streams (SPTS), have native or licensed Zixi support, and comply with Section 889 of the FY 2019 National Defense Authorization Act. MPTS is AFN’s preferred content delivery method to achieve operational efficiency within our licensing constraints. AFN will work with LMDs to verify proposed system topography and architecture and for those distributors using SPTS equipment to determine the best method to support their needs. AFN is not funded for, and cannot provide, the equipment needed for SRT distribution. All LMDs should have a stable internet service with redundant pathways, minimum bandwidth of 25 Mbps, and a static IP address for this service. AFN has identified SRT decoder options that meet the above technical specifications. Two SRT equipment options may meet LMD needs that offer an integrated and a modular solution. Integrated options are often the most straightforward choice for facilities that have existing distribution headend systems with available ASI or IP inputs. It acts as a simple, robust bridge between the incoming SRT streams and the existing infrastructure. Modular options provide versatility and can serve as a complete, self-contained distribution headend. It may be an ideal choice if the LMD needs to build a new headend or desires a single system to handle signal reception, processing, and direct-to-cable modulation. Its modularity allows for future expansion to meet changing requirements.
