Embodiment Construction

[0076] figure 1 An SDN environment including an SDN controller 1, a flow table 13 and a plurality of SDN applications 4 according to an embodiment of the present invention is shown. The SDN controller 1 is used to understand services provided in the SDN network, that is, understand multiple SDN applications 4 . Each SDN application 4 can be identified by a specific application type 5 .

[0077] According to various embodiments of the present invention, at least one service chain 3 is created and implemented in the SDN controller 1 . The service chain 3 defines the sequence of the SDN applications 4 according to their application types 5 . The SDN controller 1 can apply network traffic according to the order of the SDN application 4 in the service chain 3, that is, at least one flow 9 (such as Figure 4 As shown), the route passes through the service chain 3. The SDN application 4 of the service chain 3 then operates on the flow 9 according to its sequence. Thus, SDN appli...

Abstract

The present invention relates to a method and a software defined network, SDN, controller (1) for chaining applications (4) in a SDN. A service data table (2) is created in the SDN controller (1). In the service data table (2) a plurality of applications (4) are associated with a plurality of application types (5). Furthermore, at least one service chain is created in the SDN controller (1). The at least one service chain (3) defines an order of application types (5) running on the SDN controller (1). At least one application is registered to the service chain (3) based on its application type (5) as associated with the application (4) in the service data table (2).

Description

technical field [0001] The present invention relates to a method for linking applications in a software defined network (software defined network, SDN), and also relates to a corresponding SDN controller and a system. Specifically, the present invention provides the SDN controller with service awareness, service link infrastructure and service information sharing infrastructure. Background technique [0002] In modern business-oriented networks, especially in cloud and SDN environments, it is necessary to provide complex business products composed of linked business units, such as linked SDN applications. SDN applications can be, for example, firewalls (firewalls, FW), wide area network (wide area network, WAN) optimization controllers (WAN optimization controllers, WOC), deep packet inspection (deep packet inspection, DPI), network address translation (network address translation, NAT), application delivery controllers (application delivery controllers, ADC) and other appl...
