Abstract

A system (100) for dynamic orchestration is provided, the system configured to be used for embedding a virtual network into a physical infrastructure, the system comprising: a decision component (DC) which is configured to evaluate a performance of at least one orchestrator (O₁, O₂, . . . , O_n) based on at least one parameter (P₁, P₂, . . . , P_n), and which is configured to settle on a recomposing of the orchestrator (O₁, O₂, . . . , O_n) based on the evaluated performance and, which is configured to provide a recomposing signal (RS₁, RS₂, . . . , RS_n) when the recomposing is settled; and a recomposing component (RC) which is configured to execute the recomposing of the orchestrator (O₁, O₂, . . . , O_n) when the recomposing signal (RS₁, RS₂, . . . , RS_n) is received.

Claims

1. A system (100) for dynamic orchestration, the system configured to be used for embedding a virtual network into a physical infrastructure, the system comprising:

a decision component (DC) which is configured to

evaluate a performance of at least one orchestrator or a performance of a domain controller (DomC) or a performance of orchestrated infrastructure, based on at least one parameter (P₁, P₂, . . . , P_n), and which is configured to

settle on a recomposing of the at least one orchestrator based on the evaluated performance and, which is configured to

provide a first recomposing signal when the recomposing is settled; and

a recomposing component (RC) which is configured to execute the recomposing of the at least one orchestrator when a second recomposing signal is received.

2. The system (100) according to claim 1,

wherein the RC is configured to execute the recomposing by assigning or reassigning at least one DomC to the at least one orchestrator.

3. The system (100) according to one of the claim 1,

wherein the DC is configured to evaluate the performance based on a size of a physical infrastructure of the embedded virtual network, a number of DomCs assigned to the orchestrator, a topology of the physical infrastructure, or a performance parameter of the physical infrastructure as the at least one parameter.

4. The system (100) according to one of claim 1,

wherein the DC is configured to settle on a splitting of the orchestrator based on the evaluated performance and wherein the DC is configured to provide a first splitting signal as the first recomposing signal when the splitting is settled, wherein the RC is configured to execute a splitting of the orchestrator when a second splitting signal as the second recomposing signal is received.

5. The system (100) according to claim 4,

wherein the RC is configured to execute the splitting of the orchestrator by allocating resources for installing a new orchestrator and wherein the RC is configured to allocate at least one domain controller of the at least one orchestrator to the new orchestrator.

6. The system (100) according to one of claim 1,

wherein the DC is further configured to settle on a merging of at least two orchestrators based on the evaluated performance and wherein the DC is configured to provide a first merging signal as the first recomposing signal when the merging is settled and wherein the RC is configured to execute a merging of the at least two orchestrators when a second merging signal as the second recomposing signal is received.

7. The system (100) according to claim 6,

wherein the RC is configured to execute the merging of the at least two orchestrators by allocating resources for the merged orchestrator and wherein the RC is configured to allocate at least one domain controller to the merged orchestrator.

8. A DC for dynamic orchestration in a system for embedding a virtual network into a physical infrastructure according to claim 1.

9. A RC for dynamic orchestration in a system for embedding a virtual network into a physical infrastructure according to claim 1.

10. Computer system (1000) for embedding a virtual network into a physical infrastructure comprising:

a domain controller;

an orchestrator; and

a system (100) for dynamic orchestration according to one of claim 6.

11. The computer system (1000) according to claim 10, wherein the computer system (1000) is configured to be used in a carrier grade telecommunication or in a computer network.

12. A method for dynamic orchestration for embedding a virtual network into a physical infrastructure, the method comprising:

evaluating (Si) a performance of at least one orchestrator based on at least one parameter;

settling (S2) on a recomposing of the orchestrators based on the evaluated performance;

providing (S3) a first recomposing signal, when the recomposing is settled; and

executing (S4) the recomposing of the orchestrator when a second recomposing signal is received.

13. The method according to claim 12,

wherein the step of settling (S2) on a recomposing of the orchestrator comprises a splitting of the orchestrator and wherein a first splitting signal is provided as the first recomposing signal when the splitting is settled and wherein a splitting of the orchestrator is executed when a second splitting signal as the second recomposing signal is received.

14. The method according to one of the claim 12,

wherein the step of evaluating (Si) the performance of the at least one orchestrator comprises determining whether a failure of at least one domain controller or of at least one orchestrator or of an communication channel is present.

15. The method according to claim 12,

wherein the step of settling (S2) on a recomposing of the orchestrators comprises a merging of at least two orchestrators based on the evaluated performance and wherein a first merging signal is provided as the first recomposing signal, when the merging is settled and wherein the merging of the at least two orchestrators is executed when the a second merging signal as the second recomposing signal is received.
