Performing context-rich attribute-based services on a host
Some embodiments provide a novel method for configuring a set of service one or more nodes on a host to perform context-rich, attribute-based services on the host computer, which executes several data compute nodes (DCNs) in addition to the set of service nodes. The method uses a context-filtering node on the host to collect a first set of attributes associated with service rules processed by the set of service nodes on the host computer. The context filter also collects a second set of attributes associated with at least one data message flow of a DCN (e.g., of a virtual machine (VM) or container) executing on the host. After collecting the first and second sets of attributes, the context filtering node on the host compares the first and second sets of attributes to generate a service tag to represent a subset of the first set of attributes associated with the data message flow. The method associates this service tag with the data message flow. This service tag can then be used to identify the subset of attributes associated with the data message flow when a service node needs to process its attribute-based service rules for the data message flow. |

Detecting device masquerading in application programming interface (API) transactions
This disclosure describes a technique to determine whether a client computing device accessing an API is masquerading its device type (i.e., pretending to be a device that it is not). To this end, and according to this disclosure, the client performs certain processing requested by the server to reveal its actual processing capabilities and thereby its true device type, whereupon—once the server learns the true nature of the client device—it can take appropriate actions to mitigate or prevent further damage. To this end, during the API transaction the server returns information to the client device that causes the client device to perform certain computations or actions. The resulting activity is captured on the client computing and then transmitted back to the server, which then analyzes the data to inform its decision about the true client device type. Thus, when the server detects the true client device type (as opposed to the device type that the device is masquerading to be), it can take appropriate action to defend the site. |

The present invention discloses a modulation method and a modulation apparatus applicable to an OvXDM system, and an OvXDM system.

Therefore, in the present invention, the good performance of the waveform is retained in the corresponding domain while the transmission rate is increased. |
