Abstract
A communication device in a network may receive a stream of frames from the network, in which each frame includes one or more beacon packets. A communication protocol being used by the network may be identified by tracking a preselected field within a sequence of beacon packets, in which the preselected field varies in a first known manner for a first protocol and in a second known manner for a second protocol. The communication device may then join to the network using the identified communication protocol to transmit and receive data.
Claims20
A device comprising:
- a receiver configured to couple to a network to receive a set of frames over the network, wherein the set of frames includes a first packet and a second packet;
- at least one processor coupled to the receiver;
- a non-transistor computer-readable memory coupled to the processor and storing instructions that cause the at least one processor to:
- identify a first value of a first field in the first packet;
- identify a second value of a second field in the second packet, wherein the second field corresponds to the first field;
- compare the first value to the second value;
- and
- determine a communication protocol of the set of frames based on the comparison of the first value to the second value.
A method comprising:
- receiving a first packet and a second packet over a network;
- identifying a first value of a first field in the first packet;
- identifying a second value of a second field in the second packet, wherein the second value corresponds to the first field;
- comparing the first value to the second value;
- and
- determining a communication protocol of the network based on the comparing of the first value to the second value.
A device comprising:
- a receiver configured to couple to a network to receive a set of frames over the network, wherein the set of frames includes a first packet and a second packet;
- a network protocol detection circuit coupled to the receiver and configured to:
- identify a first value of a first field in the first packet;
- identify a second value of a second field in the second packet, wherein the second field corresponds to the first field;
- compare the first value to the second value;
- and
- determine a communication protocol of the set of frames based on the comparison of the first value to the second value.
