1. A system, comprising:
a computing device, communicatively coupled to a network, the computing device comprising: one or more computer processors; a control module stored in a memory and executed by the one or more computer processors, wherein the control module receives and responds to data requests; a forwarding module stored in the memory and executed by the one or more computer processors, wherein the forwarding module:
receives measurement traffic comprising a data request from one or more trace-routes, wherein the use of the one or more trace-routes identifies a traffic type associated with traffic received from at least one network element included in the network as measurement traffic; andforwards a response to the data request to the at least one network element, and wherein the data request is directed to the control module; and a sensor module stored in the memory and executed by the one or more computer processors, communicatively coupled to the forwarding module and the control module, wherein the sensor module:
emulates the control module by at least receiving and responding to the data request and handling data received from the forwarding module so that the data is routed from the forwarding module to the sensor module;creates an out-of-band sensor layer based at least in part on routing information from the control module, forming a sensor overlay network with dedicated paths for separation of the identified measurement traffic comprising the data request from other traffic for the network; andfilters, using at least one customizable filter, identified measurement traffic away from the other traffic that is forwarded to the control module, wherein the identified measurement traffic is based on an identified protocol; and wherein the data request is a request for basic performance measurements, wherein the basic performance measurements can be functions of rate limiting, logging, sysloging, or forwarding to the control plane any sensor traffic that meets one or more profiles. |
