Abstract
An access point providing a client device with access to a communication network detects an anomaly in packet traffic being transmitted to or received from the client device. In response, the access point performs a packet capture by triggering the release of stored packets. The access point determines an anomaly type representing a root cause of the anomaly and annotates the packet capture with the anomaly type. The access point also detects radio frequency interference exceeding a prescribed threshold and, in response, performs a spectrum capture. The packet capture, annotated with the anomaly type, and the spectrum capture are reported either automatically or in response to a request.
Claims19
A method comprising:
- detecting, by an access point providing a client device with access to a communication network, an anomaly in packet traffic, wherein the access point is configured to detect anomalies in packet traffic and anomalies in connectivity due to radio frequency interference;
- upon detecting the anomaly in the packet traffic, triggering, by the access point, a packet capture process of packets being transmitted to or received from the client device, wherein triggering the packet capture process releases the packets stored in a buffer at the access point responsive to detecting the anomaly;
- determining, by the access point, an anomaly type representing a root cause of the anomaly in the packets released from the buffer at the access point;
- annotating, by the access point, the packets with the anomaly type;
- detecting a radio frequency interference associated with the anomalies in connectivity, wherein the radio frequency interference exceeds a prescribed threshold;
- and
- responsive to detecting that the radio frequency interference exceeds the prescribed threshold, performing a spectrum capture process in addition to the packet capture process.
An access point providing a client device with access to a communication network, comprising:
- a buffer to store packets;
- a wireless radio transceiver to transmit or receive the packets to or from a client device;
- an anomaly detector to:
- detect an anomaly in packet traffic being transmitted to or received from the client device, wherein the access point is configured to detect anomalies in the packet traffic and anomalies in connectivity due to radio frequency interference;
- and
- upon detecting the anomaly in the packet traffic, triggering a packet capture process of the packets being transmitted to or received from the client device responsive to detecting the anomaly, wherein triggering the packet capture process releases the packets stored in the buffer;
- a radio frequency interference detector to:
- detecting a radio frequency interference associated with the anomalies in connectivity, wherein the radio frequency interference exceeds a prescribed threshold;
- and
- responsive to detecting that the radio frequency interference exceeds the prescribed threshold, performing a spectrum capture in addition to the packet capture process;
- an anomaly type identifier to determine an anomaly type representing a root cause of the anomaly in the packets released from the buffer;
- and
- an annotator to annotate the packets with the anomaly type.
A non-transitory computer readable medium comprising computer executable instructions stored thereon that, when executed by a processor in an access point of a communication network, cause the processor to:
- detect an anomaly in packets being transmitted to or received from a client device by the access point, wherein the access point is configured to detect anomalies in packet traffic and anomalies in connectivity due to radio frequency interference;
- upon detecting the anomaly in the packet traffic, triggering a packet capture process of the packets being transmitted to or received from the client device by the access point, wherein triggering the packet capture process releases the packets stored in a buffer at the access point responsive to detecting the anomaly;
- determine an anomaly type representing a root cause of the anomaly in the packets released from the buffer at the access point;
- annotate the packets with the anomaly type;
- report the packets annotated with the anomaly type;
- detect a radio frequency interference associated with the anomalies in connectivity, wherein the radio frequency interference exceeds a prescribed threshold;
- and
- responsive to detecting that the radio frequency interference exceeds the prescribed threshold, perform a spectrum capture in addition to the packet capture process.
