2. Overview of Ethernet and MIL-STD-1553
2.1 Ethernet
Ethernet is a widely adopted technology for local area networks (LANs) that facilitates high-speed data communication between devices. Developed initially in the 1970s and standardized by the IEEE 802.3 committee, Ethernet has undergone significant evolution, offering various standards to meet diverse needs:
- Data Rates: Ethernet supports a range of speeds from 10 Mbps (10BASE-T) to 400 Gbps (400GBASE-R).
- Frame Structure: Ethernet frames consist of several fields, including the destination MAC address, source MAC address, EtherType/Length, payload, and Frame Check Sequence (FCS).
- Protocols: Operating primarily at the Data Link layer (Layer 2) of the OSI model, Ethernet uses protocols such as Address Resolution Protocol (ARP) for mapping IP addresses to MAC addresses.
2.2 MIL-STD-1553
MIL-STD-1553 is a military standard for serial data buses used predominantly in aerospace and defense applications. Established in the 1970s, MIL-STD-1553 defines a communication protocol that ensures high reliability and fault tolerance:
- Bus Structure: MIL-STD-1553 employs a dual-redundant, balanced-line bus structure that includes a data bus, control bus, and timing bus.
- Message Format: The standard specifies a message format comprising a command word, data word(s), and status word.
- Protocols: Operating at both the Physical layer (Layer 1) and Data Link layer (Layer 2) of the OSI model, MIL-STD-1553 involves bus controllers, remote terminals, and bus monitors.
