Glossary

A

Term	Definition
RADVD (Router	RADVD is an open-source software product
Advertisement Daemon)	that uses the Neighbor Discovery Protocol
	(NDP) to listen for router solicitations in the IPv6
	LAN. It responds with router advertisements to
	support stateless address auto-configuration.
	When a new host connects to the network, it
	sends a request for its configuration
	parameters, and the router responds with a
	router advertisement packet that contains the
	network-layer configuration parameters
	including IPv6 prefixes. The node takes the
	prefix and extends it to a full 128 bit address by
	adding an EUID based on its hardware address.
Request to Send (RTS)	The packet size, in bytes, that requires an RTS/
Threshold	Clear to Send (CTS) handshake before sending.
	A low setting can be useful in areas where many
	client devices are associating with the wireless
	device, or in areas where the clients are far
	apart and can detect only the access point but
	not other clients. Although a low threshold value
	consumes more bandwidth and reduces the
	throughput of the packet, frequent RTS packets
	can help the network to recover from
	interference or collisions.
Routing Information	This protocol uses use distance vectors to
Protocol (RIP)	mathematically compare routes to identify the
	best path to any given destination address. RIP
	sends routing-update messages at regular
	intervals and when the network topology
	changes. Upon receiving a RIP message, a
	router updates its routing table and transmits
	the updates to other routers. RIP prevents loops
	and has features to provide stability despite
	potentially rapid changes in a network's
	topology.
	RIPv2 supports subnet masks, allows more
	information to be included in RIP packets, and
	provides a simple authentication mechanism
	that is not supported by RIP.
