Glossary
Access Control
Protocol (ACP)
Bay Networks software utility that provides a wide range of security features
to Annex, Remote Annex, and Remote Access Concentrator users, including
password authentication, dialback, in accord with user profiles, and access to
third party authentication systems, such as Kerberos.
adjacent host
A network device that is reachable without an intermediate hop; that is, a
device that is directly attached to the same network as the router.
BayDVS
Former name of Bay Networks Dial VPN Services.
care-of address
A termination point of a tunnel heading towards the remote node. The care-of
address, which is usually the address of the Dial VPN network access server,
is specified to the gateway during the connection process. When the gateway
encapsulates the frame relay packet into a GRE packet, it includes the care-of
address.
CHAP
Challenge Handshake Authentication Protocol. A method of establishing
security on PPP links where the peers must share a plain text “secret.” The
caller sends a challenge message to its receiving peer and the receiver
responds with a value it calculated based on the secret. The first peer then
matches the response with its own calculation of what the response should be.
If the values match, the link is established.
CPE router
The router on the customer’s home network (that is, the customer premises)
that receives and sends the data packet via the frame relay connection between
the Dial VPN network and the corporate home network.
corporate “home
network
A corporate (or customer) network to which a user at a remote node wants to
connect.
Customer Premise
Equipment (CPE)
A device at a customer site that connects to the Dial VPN network via a WAN
link. With Dial VPN, the customer site connects to a Dial VPN network by
means of a frame relay network.
