Dynamic service chaining and late binding
A visibility platform can be used to monitor traffic traversing private cloud infrastructures and/or public cloud infrastructures. In some instances, the traffic is provided to a set of network services that are accessible to the visibility platform. These network services can be provisioned in a serial or parallel fashion. Network service chaining can be used to ensure that traffic streams skip unnecessary network services and receive only those network services that are needed. For example, an email service chain can include virus, spam, and phishing detection, while a video streaming service chain can include traffic shaping policies to satisfy quality of service (QoS) guarantees. When the visibility platform is represented as a graph that makes use of action sets, network service chains can be readily created or destroyed on demand.
1. A method comprising:
receiving first input indicative of a selection of a map that includes a rule for filtering data packets from amongst a plurality of maps that were not bound to network objects during construction of the plurality of maps;
receiving second input indicative of a selection of (i) a source network object of a network visibility appliance and (ii) a destination network object of the network visibility appliance; and
binding the map to the network visibility appliance prior to runtime by associating the map with the source network object and the destination network object in a data structure upon deployment of the map within the network visibility appliance.
2. The method of claim 1 , wherein said binding is performed by a controller that is communicatively connected to the network visibility appliance.
3. The method of claim 1 , wherein said binding further comprises editing an action set that is associated with a programmable data structure corresponding to the map.
4. The method of claim 1 , wherein the network visibility appliance is configured to receive traffic from an agent hosted on a virtual machine belonging to one of a plurality of tenants to which a cloud computing platform is accessible.
5. A processing system comprising:
a memory;
a network interface;
a processor coupled to the network interface and the memory, and configured to control the processing system to:
receive first input indicative of a selection of a map that includes a rule for filtering data packets from amongst a plurality of maps that were not bound to network objects during construction of the plurality of maps;
receive second input indicative of a selection of (i) a source network object of a network visibility appliance and (ii) a destination network object of the network visibility appliance; and
bind the map to the network visibility appliance prior to runtime by associating the map with the source network object and the destination network object in a data structure upon deployment of the map within the network visibility appliance.
6. The processing system of claim 5 , wherein saki binding the map to the network visibility appliance is to be performed by a controller that is communicatively connected to the network visibility appliance.
7. The processing system of claim 5 , wherein said binding the map to the network visibility appliance comprises editing an action set that is associated with a programmable data structure corresponding to the map.
8. The processing system of claim 5 , wherein the network visibility appliance is configured to receive traffic from an agent hosted on a virtual machine belonging to one of a plurality of tenants to which a cloud computing platform is accessible.
9. A non-transitory machine-readable storage medium having stored therein instructions, execution of which in a processing system causes the processing system to perform operations comprising:
receiving first input indicative of a selection of a map that includes a rule for filtering data packets from amongst a plurality of maps that were not bound to network objects during construction of the plurality of maps;
receiving second input indicative of a selection of (i) a source network object of a network visibility appliance and (ii) a destination network object of the network visibility appliance; and
binding the map to the network visibility appliance prior to runtime by associating the map with the source network object and the destination network object in a data structure upon deployment of the map within the network visibility appliance.
10. The non-transitory machine-readable storage medium of claim 9 , wherein said binding is performed by a controller that is communicatively connected to the network visibility appliance.
11. The non-transitory machine-readable storage medium of claim 9 , wherein said binding further comprises editing an action set that is associated with a programmable data structure corresponding to the map.
12. The non-transitory machine-readable storage medium of claim 9 , wherein the network visibility appliance is configured to receive traffic from an agent hosted on a virtual machine belonging to one of a plurality of tenants to which a cloud computing platform is accessible.
