For PPP (PPPoE and PPPoA), IP address management will most
likely be dynamic. However, static IP address management can ex
-
ist. PPPoA has the following implementations of IP management:
• Static IP address management over PPP.
• Dynamic IP address management over PPP. In this case, the
IP address is requested and assigned at the time of the con-
nection.
Authentication is commonly used since it provides security for
the connection. In the case of PPP, identification is controlled
with a user name and password. These will be required in order
to open a link with the ISP. Identification can use either the PAP
or the CHAP authentication mechanisms. The PPP session is
opened with the Broadband-Remote Access Server (B-RAS). The
LCP session is handled between the B-RAS and the PC (CPE) to
manage the authentication of the user name and password.
