Glossary

packet	A block of data in a standard format for transmission.
PAP	Password Authentication Protocol is a simple PPP authentication mechanism in which a cleartext
	username and password are transmitted to prove identity.
Payload	The contents of a request packet.
PDU	Protocol Data Unit—An SNMP compliant request, response, or trap message.
PE Router	Provider Edge router—a router located at the edge of the provider’s MPLS core network.
POP	Point of Presence is the dial-in point or connection point for users connecting to an ISP.
PPD	Packet Processing Delay is the amount of time required for each peer to process the maximum amount
	of data buffered in their offered receive packet window. The PPD is the value exchanged between the
	LAC and LNS when a call is established. For the LNS, this number should be small. For an LAC
	supporting modem connections, this number could be significant.

PPP

Profile

Point-to-Point Protocol—a multiprotocol and includes UDP, Frame Relay PVC, and X.25 VC.

A collection of one or more attributes that describe how a user should be configured; for example, a profile may contain an attribute whose value specifies the type of connection service to provide the user, such as PPP, SLIP, or Telnet. Profiles can be set up for a specific user or can be shared amongst users.

Provider	Service Provider—A provider who operates the access networks and MPLS backbone and provides
	MPLS VPN service on the backbone.
PSTN	Public Switched Telephone Network enables async PPP through modems.

Quality of Service A given Quality of Service level is sometimes required for a given user being tunneled between an

(QOS)	LNS-LAC pair. For this scenario, a unique L2TP tunnel is created (generally on top of a new SVC) and
	encapsulated directly on top of the media providing the indicated QOS.

RAC Client

RADIUS

RADIUS Client

The IOS DHCP client used to generate requests for host addresses and subnets for non-PPP clients.

Remote Authentication Dial-In User Service. The RADIUS protocol provides a method that allows multiple dial-in Network Access Server (NAS) devices to share a common authentication database.

A Network Access Server (NAS) operates as a client of RADIUS. The client is responsible for passing user information to designated RADIUS servers, and then acting on the response that is returned. A RADIUS server can act as a proxy client to other RADIUS servers.
