Abstract

Techniques for implementing a single-addressable virtual topology element (VTE) in a virtual topology. A VTE in a virtual topology may be distributed as multiple instantiated elements in a physical topology. However, the multiple instantiated elements are addressable as a single entity. Obtaining information associated with the VTE includes obtaining and aggregating information from each of the instantiated elements. Applying an overall configuration to the VTE includes determining a respective configuration for each instantiated element based on the overall configuration, and applying the respective configuration to each instantiated element.

First claim

What is claimed is:

1. A non-transitory computer readable medium comprising instructions which, when executed by one or more hardware processors, cause performance of operations comprising:
receiving a request for information associated with a virtual topology element (VTE) in a virtual topology;
identifying a plurality of instantiated elements, in a physical topology, that is configured to perform a function associated with the VTE in the virtual topology;
obtaining a set of information from each of the plurality of instantiated elements;
wherein obtaining the set of information from a particular instantiated element of the plurality of instantiated elements comprises:
identifying data received by the particular instantiated element;
determining that a first portion of the data received by the particular instantiated element corresponds to the VTE in the virtual topology, and a second portion of the data received by the particular instantiated element corresponds to another VTE in the virtual topology;
selecting the first portion of the data received by the particular instantiated element to be included in the set of information from the particular instantiated element, without selecting the second portion of the data received by the particular instantiated element to be included in the set of information from the particular instantiated element; and

aggregating the set of information from each of the plurality of instantiated elements to obtain the information associated with the VTE in the virtual topology.

2. The medium of claim 1 , wherein the operations further comprise:
identifying a set of functions associated with the VTE in the virtual topology; and
executing the plurality of instantiated elements in the physical topology, such that each of the plurality of instantiated elements performs at least one of the set of functions.

3. The medium of claim 1 , wherein each of the plurality of instantiated elements performs a same function associated with the VTE in the virtual topology.

4. The medium of claim 1 , wherein each of the plurality of instantiated elements performs a different function associated with the VTE in the virtual topology.

5. The medium of claim 1 , wherein the operations further comprise: presenting the information associated with the VTE in the virtual topology, aggregated from the set of information from each of the plurality of instantiated elements, at a user interface.

6. The medium of claim 1 , wherein aggregating the set of information from each of the plurality of instantiated elements comprises transmitting the set of information, from each of the plurality of instantiated elements, to an aggregation component.

7. The medium of claim 1 , wherein aggregating the set of information from each of the plurality of instantiated elements is performed subsequent to receiving the request for information associated with the VTE in the virtual topology.

8. The medium of claim 1 , wherein aggregating the set of information from each of the plurality of instantiated elements is performed prior to receiving the request for information associated with the VTE in the virtual topology.

9. The medium of claim 1 , wherein aggregating the set of information from each of the plurality of instantiated elements comprises:
identifying metadata included in the set of information that identifies the set of information as being obtained from a particular element of the plurality of instantiated elements;
removing the metadata from the set of information; and
transmitting the set of information, without the metadata, to an aggregation component.

10. The medium of claim 1 , wherein aggregating the set of information from each of the plurality of instantiated elements comprises:
obtaining aggregated information based on the set of information from each of the plurality of instantiated elements; and
adding metadata, to the aggregated information, that identifies the aggregated information as being associated with the VTE in the virtual topology.

11. The medium of claim 1 , wherein aggregating the set of information from each of the plurality of instantiated elements comprises:
determining a chronological order in which the set of information is received by each of the plurality of instantiated elements; and
generating a single data set, including the set of information from each of the plurality of instantiated elements, in accordance with the chronological order.

12. The medium of claim 1 , wherein aggregating the set of information from each of the plurality of instantiated elements comprises:
computing a statistic corresponding to the set of information from each of the plurality of instantiated elements.

13. The medium of claim 12 , wherein the statistic comprises a total amount of data received by each of the plurality of instantiated elements over a particular time period.

14. The medium of claim 12 , wherein the statistic comprises a total number of errors generated by each of the plurality of instantiated elements over a particular time period.

15. The medium of claim 1 , wherein the VTE is a single addressable component that is mapped to a distributed implementation comprising the plurality of instantiated elements.

16. A method, comprising:
receiving a request for information associated with a virtual topology element (VTE) in a virtual topology;
identifying a plurality of instantiated elements, in a physical topology, that is configured to perform a function associated with the VTE in the virtual topology;
obtaining a set of information from each of the plurality of instantiated elements;
wherein obtaining the set of information from a particular instantiated element of the plurality of instantiated elements comprises:
identifying data received by the particular instantiated element;
determining that a first portion of the data received by the particular instantiated element corresponds to the VTE in the virtual topology, and a second portion of the data received by the particular instantiated element corresponds to another VTE in the virtual topology;
selecting the first portion of the data received by the particular instantiated element to be included in the set of information from the particular instantiated element, without selecting the second portion of the data received by the particular instantiated element to be included in the set of information from the particular instantiated element; and

aggregating the set of information from each of the plurality of instantiated elements to obtain the information associated with the VTE in the virtual topology.

17. A system comprising:
at least one device including a hardware processor; and
the system configured to perform operations comprising:
receiving a request for information associated with a virtual topology element (VTE) in a virtual topology;
identifying a plurality of instantiated elements, in a physical topology, that is configured to perform a function associated with the VTE in the virtual topology;
obtaining a set of information from each of the plurality of instantiated elements;
wherein obtaining the set of information from a particular instantiated element of the plurality of instantiated elements comprises:
identifying data received by the particular instantiated element;
determining that a first portion of the data received by the particular instantiated element corresponds to the VTE in the virtual topology, and a second portion of the data received by the particular instantiated element corresponds to another VTE in the virtual topology;
selecting the
