Methods, systems and computer readable media for network tapping and packet brokering in wireless networks
First Claim
1. A method for network tapping and packet brokering in wireless networks, the method comprising:
- using a wireless network tap to tap a signal transmitted between devices separate from the wireless network tap in a wireless network;
determining that the signal is a valid signal according to a wireless network protocol;
in response to determining that the signal is a valid signal according to the wireless network protocol, demodulating the signal into a sequence of bits arranged according to the wireless network protocol;
in response to determining that the signal is not a valid signal according to the wireless network protocol, generating an indication that the signal is not a valid signal according to the wireless network protocol;
generating a frame in a format compatible with a network tapping and packet brokering system;
inserting, in the frame, at least some of the bits, wherein inserting, in the frame, at least some of the bits includes inserting a payload of a wireless network protocol packet in an Ethernet frame; and
transmitting the frame from a network tapping and packet brokering system interface of the wireless network tap to the network tapping and packet brokering system.

Abstract
A method for network tapping and packet brokering in wireless networks includes tapping a signal in a wireless network and determining whether the signal is a valid signal according to a wireless network protocol. In response to determining that the signal is a valid signal according to the wireless network protocol, the signal is demodulated into a sequence of bits arranged according to the wireless network protocol. In response to determining that the signal is not a valid signal according to the wireless network protocol, an indication that the signal is not a valid signal according to the wireless network protocol is generated. A packet in a format compatible with a network tapping and packet brokering system is generated. At least some of the bits or the indication is inserted in the packet. The packet is transmitted to the network tapping and packet brokering system.

19. A non-transitory computer readable medium having stored thereon executable instructions that when executed by the processor of a computer control the computer to perform steps comprising:
-
using a wireless network tap to tap a signal transmitted between devices separate from the wireless network tap in a wireless network; determining that the signal is a valid signal according to a wireless network protocol; in response to determining that the signal is a valid signal according to the wireless network protocol, demodulating the signal into a sequence of bits arranged according to the wireless network protocol; in response to determining that the signal is not a valid signal according to the wireless network protocol, generating an indication that the signal is not a valid signal according to the wireless network protocol; generating a frame in a format compatible with a network tapping and packet brokering system; inserting, in the frame, at least some of the bits wherein inserting, in the frame, at least some of the bits includes inserting a payload of a wireless network protocol packet in an Ethernet frame; and transmitting the frame from a network tapping and packet brokering system interface of the wireless network tap to the network tapping and packet brokering system.
