specific Embodiment 1

[0101] Figure 14 is a schematic diagram of a service function chain application scenario according to Embodiment 1 of the present invention, as shown in Figure 14 shown, including the following steps:

[0102] Step S1401, the controller configures the user data to execute the operation of SFP as the service function chain of NAT->DPI->firewall; and configures the NAT service to generate a forwarding table and send it to the switch, but the firewall service forwarding table cannot be sent to the switch;

[0103] Step S1402, the controller configures the parent SFP ID to be 100, the service chain of "NAT->DPI->firewall"; the child SFP ID is 1, and the service chain of "DPI->firewall" to each network element in the SFC domain;

[0104] Step S1403, the above-mentioned user on the intranet sends the first message to access the Internet. After the switch looks up the table and is filtered by the classifier, it is found that the message has no session in the local area and is the ...

Abstract

The invention provides a message transmitting method and device. The method includes the following steps that: a parent service function path identifier (SFP ID) and one or more child SFP IDs corresponding to the parent SFP ID are obtained; a message from user equipment is received; a specified parent SFP ID and a specified child SFP ID corresponding to the type of the message are obtained; and the message is transmitted to a parent SFP corresponding to the specified parent SFP ID or a child SFP corresponding to the specified child SFP ID. With the message transmitting method and device of the invention adopted, the problem that an SFC (Service Function Chain) cannot change a service chain path according to policies in some conditions in the prior art can be solved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a message sending method and device. Background technique [0002] Service Function Chaining (SFC for short) is a network technology currently being researched and standardized. Since the development of the data center network to the Overlay network, the edge of the network has become the dividing point between the virtual network and the physical network. The edge of the network is a Server or ToR, and may be a Gateway (Gateway). However, Overlay technology does not solve all problems. There are still many middleware (Middleware) in the data center, such as firewalls / load balancers, etc. These devices are processed based on user services. If these devices are traversed through tunnels, it is obviously a No way. [0003] This deployment model of the data center requires that the virtual firewall / load balancer can be deployed arbitrarily in the network, that is, it has nothing...
