ONFIGURATION
As shown in Figure
Routing/switching component: As the main part of routers and switches, it
■
performs complete router/switcher functions and is also the core of user
management control.
Independent service component: Also known as the open application platform
■
(OAP), it is the main part open for development by a third party and is mainly
used to provide various unique service functions.
Interface-connecting component: It connects the interface of the
routing/switching component to that of the independent service component. It
allows the devices of two manufacturers to be interconnected.
ACFP cooperation means that the independent service component can send
instructions to the routing/switching component to change its functions. ACFP
cooperation is mainly implemented through the simple network management
protocol (SNMP). By performing as a network management system, the
independent service component sends various SNMP commands to the
routing/switching component. The routing/switching component can execute the
instructions sent because it supports SNMP agent. In this process, the cooperating
MIB is the key to associating the two components with each other.
ACFP cooperation provides a mechanism that enables the ACFP client (namely, the
independent service component shown in
ACFP server (namely, the routing/switching component shown in
implementing the following functions:
Mirroring and redirecting the traffic on the ACFP server to the ACFP client
■
Permitting/denying the traffic from the ACFP server
■
Carrying the context ID in a packet to enable the ACFP server and ACFP client
■
to communicate the packet context with each other. The detailed procedure is
as follows: The ACFP server maintains a context table that can be queried with
context ID. Each context ID corresponds with an ACFP cooperation policy that
contains information including inbound interface and outbound interface of
the packet, and cooperation rules. When the packet received by the ACFP
server is redirected or mirrored to the ACFP client after matching a cooperation
rule, the packet carries the context ID of the cooperation policy to which the
cooperation rule belongs. When the redirected packet is returned from the
ACFP client, the packet also carries the context ID. With the context ID, the
ACFP server determines that the packet is returned after being redirected and
then forwards the packet normally.
For the ACFP client to control traffic better, the two-level structure of cooperation
policy and cooperation rules are set in the cooperation to manage the traffic
matching the cooperation rule based on the cooperation policy, achieving flexible
traffic management.
For effective support of the cooperation in the client/server mode and granular
and flexible rule settings, cooperation contents are divided into four parts: ACFP
server information, ACFP client information, ACFP cooperation policy, and ACFP
cooperation rule, all of which are stored in the ACFP server.
