Configuring ACSEI
ACSEI overview
As a private protocol, ACSEI provides a method for exchanging information between ACFP clients and
ACFP server. It well supports Application Control Forwarding Protocol (ACFP) collaboration, ensuring
valid information interaction between the ACFP clients and the ACFP server, so that the ACFP server and
clients can cooperate to run a service.
As a supporting protocol of ACFP, ACSEI also has two entities: server and client.
• ACSEI server is integrated into the software system (Comware) of the device and is supported by the
device.
• ACSEI client is implemented in two ways. One way is to integrate it into the system software
(Comware) of the device. In this way it is a function supported by the device. The other way is to
integrate it into the software system of the OAP module. In this way it is a function supported by the
OAP module. Hardware and configurations needed in the two implementations are different. This
chapter will introduce them respectively.
NOTE:
•
ACFP is designed based on the Open Application Architecture (OAA).
• OAP is designed for new services. On OAP module runs the operating system. You can load various
service software, such as security, voice, and so on as needed. For more information about the OAP
module, see the chapter “Configuring OAP modules.”
• This manual covers the configuration of the ACSEI server integrated into the software system of the
router.
ACSEI functions
ACSEI mainly provides the following functions:
• Registration and deregistration of an ACSEI client to the ACSEI server.
• ID assignment. The ACSEI server assigns IDs to ACSEI clients to distinguish between them.
• Mutual monitoring and awareness between an ACSEI client and the ACSEI server.
• Information interaction between the ACSEI server and ACSEI clients, including clock
synchronization.
• Control of the ACSEI clients on the ACSEI server. For example, you can restart ACSEI client on the
ACSEI server.
ACSEI timers
An ACSEI server uses two timers, the clock synchronization timer and the monitoring timer.
• The clock synchronization timer is used to periodically trigger the ACSEI server to send clock
synchronization advertisements to ACSEI clients. You can set this timer through command lines.
