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.

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.

·           The monitoring timer is used to periodically trigger the ACSEI server to send monitoring requests to ACSEI clients. You can set this timer through command lines.

An ACSEI client starts two timers, the registration timer and the monitoring timer.

·           The registration timer is used to periodically trigger the ACSEI client to multicast registration requests (with the multicast MAC address being 010F-E200-0021). You cannot set this timer.

·           The monitoring timer is used to periodically trigger the ACSEI client to send monitoring requests to the ACSEI server. You cannot set this timer.

ACSEI startup and running

ACSEI starts up and runs in the following procedures:

1.      Run the ACSEI client application to enable ACSEI client.

2.      Start up the router and enable the ACSEI server function on it.

3.      The ACSEI client multicasts registration requests.

4.      After the ACSEI server receives a valid registration request, it negotiates parameters with the ACSEI client and establishes connection with the client if the negotiation succeeds.

5.      The ACSEI server and the ACSEI client mutually monitor the connection.

6.      If detecting the disconnection of the ACSEI client, the ACFP server will remove the configuration and policies associated with the client.
