T500SB IP-to-IP Space Bridge
Overview
The RT Logic T500SB IP-to-IP Space Bridge systems provide a seamless bidirectional OSI Layer 2 Bridge or Layer 3 Routing interface between two terrestrial Ethernet (IEEE 802.3ab, 1000BASE-T) networks connected via satellite up- and downlink, or between a terrestrial Ethernet and an Ethernet network on a space vehicle.
Product Description
For the Layer 2 forward link, the T500SB accepts Ethernet packets into Gigabit Ethernet interfaces, performs CCSDS encapsulation, and generates AOS frames for transmission to the forward link. As part of the CCSDS encapsulation service, Reed-Solomon Forward Error Correction (FEC) encoding is applied to the input data. For the Layer 2 return link, the T500SB provides frame synchronization, derandomization, Reed-Solomon FEC, and Ethernet data distribution via Gigabit Ethernet. Similar to the Layer 2 process, the Layer 3 process supports standard routing protocols to provide ground-to-space routing using standard CCSDS encapsulation and AOS framing.
