For the ACFP client to better control traffic, the two-level structure of collaboration policy and
collaboration rules is set in the collaboration to manage the traffic matching the collaboration rule based
on the collaboration policy, implementing flexible traffic management.
To better support the Client/Server collaboration mode and granularly and flexibly set different rules, the
collaboration content is divided into four parts: ACFP server information, ACFP client information, ACFP
collaboration policy and ACFP collaboration rules. These four parts of information are saved in the ACFP
server.
An ACFP server supports multiple ACFP clients. Therefore, ACFP client information, ACFP collaboration
policy, and ACFP collaboration rules are organized in the form of tables.
ACFP server information is generated by the ACFP server itself. ACFP client information, ACFP
collaboration policy, and ACFP collaboration rules are generated on the ACFP client and sent to the
ACFP server through the collaboration MIB or collaboration protocol.
ACFP information overview
ACFP server information
ACFP server information contains the following:
• Supported working modes—host, pass-through, mirroring, and redirect. An ACFP server can
support multiple working modes among these four at the same time. The ACFP server and client(s)
can collaborate with each other only when the ACFP server supports the working mode of the ACFP
client.
• Maximum expiration time of the supported collaboration policy—This indicates for how long the
collaboration policy of the ACFP server will remain valid.
• Whether the ACFP server can permanently save the collaboration policy—It mainly refers to
whether the ACFP server can keep the original collaboration policy after reboot.
• Currently supported context ID type—The location of the context ID in the packet is HGPlus-context
(carrying the preamble HGPlus as the context ID).
The above-mentioned information indicates the collaboration capabilities of an ACFP server. ACFP
clients can access this information through a collaboration protocol or collaboration MIB.
ACFP client information
ACFP client information contains the following:
• ACFP client identifier. It can be assigned by the ACFP server through a collaboration protocol or
specified by the network administrator to make sure that each ACFP client has a unique client ID on
the ACFP server.
• Description—ACFP client description information.
• Hw-Info—ACFP client hardware type, version number, and so on.
• OS-Info—System name and version number of the ACFP client.
• App-Info—Application software type and version number of the ACFP client.
• Client IP—ACFP client IP address.
• Client Mode—Working mode currently supported by the ACFP client, namely, the combination of
the host, pass-through, mirroring, and redirect modes.
ACFP collaboration policy
ACFP collaboration policy refers to the collaboration policy that the ACFP client sends to the ACFP server
for application. The policy information is as follows:
