Embodiment

[0039] The following takes the deployment of a load balancing data center and the configuration of network traffic monitoring services in the H College of A University as an example to illustrate the process of the forwarding strategy conversion method.

[0040] Such as figure 1 As shown, the network topology of this embodiment is composed of 1 core switch, 2 SDN switches S1 and S2, 5 servers, and several host / terminal devices. The whole network is divided into six network segments, network segment 1: network research institute (10.20.4.0 / 24); network segment 2: graduate student laboratory (10.20.5.0 / 24); network segment 3: cloud laboratory (10.20.6.0) / 24); Network segment 4: Cloud laboratory server group (10.20.7.0 / 24). The four servers in segment 4 are used to run the cloud laboratory operating system. Network segment 5: Audit server (10.20.8.0 / 24), which can selectively back up data packets according to the needs of the administrator for post-audit. Network segment 6: Data ...

Abstract

The invention discloses a service function chaining construction method for a SDN (Software Defined Network), which can dispose a network service function blocks (SFB) instance at a network node specific to a network service request. The method comprises: first, a controller creating a service function chaining according to a network service demand provided by a user; and creating a service function instance chaining according to network node information, wherein the service function chaining is composed of service functions, and the service function instance chaining is composed of SFBs. The service function is supported by SFBs; the main task of a classification SFB type is classifying data packets according to metadata; the main task of a scheduling SFB type is performing scheduling treatment on data packets; if a plurality of data streams have to go out from a same port, the sending order sequence and rhythm for the data streams are set. The classification greatly simplifies current SFB types, and guarantees SFB type conciseness.

Description

Technical field [0001] The present invention relates to the field of SDN (Software Defined Network, software defined network) and service function chains, and specifically relates to a division of service function block classes and a description method of service function blocks (Service Function Block) based on this division. Background technique [0002] New data center networks and network cloud architectures require more flexible deployment models to support a variety of applications and related network services. This includes traditional network services such as firewalls, service load balancers, and applications that operate on network data. Moreover, since each individual tenant is an isolated client organization connected to the data center, in the context of multi-tenancy, these services must meet the needs of all tenants when they are delivered. At the same time, each tenant may also need Unique capabilities, or tailor-made service features. [0003] In the past, there ...
