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.
