Abstract: A network device may intercept, from an application associated with a user space of the network device, a request message to join a multicast group or to leave the multicast group. The request message may be addressed to a kernel of the network device. The network device may direct the request message to a service daemon associated with the user space of the network device. The network device may determine, using the service daemon, whether another application associated with the user space is a member of the multicast group. The network device may selectively generate, using the service daemon and based on whether the other application associated with the user space is the member of the multicast group, an advertisement message based on the request message, and transmit the advertisement message when the advertisement message is generated.

Abstract: An intercept library of a network device may detect a socket system call from an application associated with a user space of the network device. The intercept library may be associated with the user space, and the socket system call may be addressed to a kernel associated with the network device. The intercept library may generate an intercept socket based on the socket system call, and may detect a subscription for asynchronous network state information, wherein the subscription may be generated by the application. The intercept library may provide the subscription to a service daemon via the intercept socket.

Abstract: A network device intercepts, from an application associated with a user space, a request message associated with obtaining information regarding a network state from a kernel. The network device directs the request message to a service daemon of the user space based on intercepting the request message, and determines, using the service daemon, network state information regarding the network state. The network device intercepts, from the service daemon, a response message associated with providing the network state information to the application, and directs an altered response message to the application based on intercepting the response message such that the altered response message identifies the kernel as a source of the response message and not the service daemon as the source of the response message.
