Study Notes
ALOHA Protocol
- The primary characteristic of the ALOHA protocol is its use of a random access method.
- When a node experiences a collision in the ALOHA protocol, it waits for a random amount of time before retransmitting the data.
Random-Access Protocols
- The rate of transmission for a transmitting node in a random-access protocol is variable.
- Random access methods get their name because nodes access the channel randomly.
- The key feature of random access protocols regarding station superiority is that no single node has priority over others.
Addressing Protocols
- The Address Resolution Protocol (ARP) is used to map a logical address to its corresponding physical address.
- The Reverse Address Resolution Protocol (RARP) uses its own MAC address as the target and an IP address of 0.0.0.0.
- The Dynamic Host Configuration Protocol (DHCP) is more versatile than BOOTP and supports the mobility of devices.
DHCP and BOOTP
- DHCP allows assignment of subnet mask, default gateway, DNS address, and IP address of a boot server.
- In ARP, an ARP request is broadcast and an ARP reply is unicast.
