摘要： In one embodiment, a device in a serial network de-multiplexes a stream of traffic in the serial network into a plurality of data streams. A particular one of the data streams is associated with a particular endpoint in the serial network. The device determines that data from the particular data stream associated with the particular endpoint should be reported to an entity external to the serial network based on an event indicated by the data from the particular data stream. The device quantizes the data from the particular data stream. The device applies compression to the quantized data to form a compressed representation of the particular data stream. The applied compression is selected based on a data type associated with the data. The device sends a compressed representation of the particular data stream to the external entity as Internet Protocol (IP) traffic.

摘要： Stateless network address privacy may be provided. A data packing may be received with an obfuscated destination address and an un-obfuscated source address. An un-obfuscated destination address may be determined based on the obfuscated destination address. An obfuscated source address may be determined based on the un-obfuscated source address. The obfuscated destination address may be replaced with the un-obfuscated destination address and the un-obfuscated source address may be replaced with the obfuscated source address. The packet may be forwarded.

摘要： In one aspect, a method of IP obfuscation of a user device includes receiving, over an Extendible Authentication Protocol (EAP) session between a user device and a network access point, location preferences of the user device, generating, based on the location preferences or a network policy, a geohash for the user device, identifying, for the user device, an IP anchor, sending, over the EAP session, the geohash to the user device, and receiving, from the user device, network traffic, wherein the network access point utilizes the geohash and the IP anchor to route the network traffic for the user device and obfuscate IP address of the user device from third-party access.
