Embodiment Construction

[0065] Hereinafter, some embodiments of the present invention are described in detail with reference to the accompanying drawings, in which the features of the embodiments can be freely combined with each other unless otherwise specified. It is to be expressly understood, however, that the description of certain embodiments has been given by way of example only, and it is in no way intended to be construed as limiting the invention to the disclosed details.

[0066] Furthermore, it should be understood that an apparatus is configured to perform a corresponding method, although only an apparatus or only a method is described in some cases.

[0067] There is some skepticism from the considerations above that a one-to-one mapping of a chain's physical service function or even its decomposed components to a virtual SF in a VM is an optimal migration to a service function link in the cloud.

[0068] according to figure 1 and figure 2 In the architecture shown, different SFs may ...

Abstract

The present invention relates to a method, an apparatus and a computer program product related to service function chain management. Management functionality is directed to efficient controlling software configuration for service function chains and to adaptively invoke, reconfigure or stop virtual machines for load balancing purposes to cope with the dynamic life traffic.

Description

technical field [0001] The present invention relates to a method, device and computer program product related to service function chain management. More specifically, the present invention relates to methods, apparatus and computer program products related to loading and software configuration control of service function chains. Background technique [0002] One way to reduce the TCO of an operator network is to virtualize network functions and use common data center (DC) hardware for different network functions (see ETSI NFV (Network Functions Virtualization Research Group) document). [0003] This also applies to service function links. Service function chaining typically observes, alters, or even terminates and re-establishes the session flow between a user device and an application platform (Web, video, VoIP, etc.) by invoking a set of service functions in a given order. Service functions involved in a given service function chain (SFC, hereinafter sometimes referred t...
