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.
Claims20
A method, comprising:
- detecting, by a first intercept library of a network device, a first socket system call from a first application associated with a user space of the network device,
- wherein the first intercept library is associated with the user space of the network device,
- wherein the first socket system call is addressed to a kernel associated with the network device;
- generating, by the first intercept library of the network device, a first intercept socket based on the first socket system call;
- detecting, by the first intercept library of the network device, a first request for a subscription for first asynchronous network state information addressed to a socket address of the kernel associated with the network device,
- wherein the first request for the subscription for the first asynchronous network state information is generated by the first application,
- wherein the first application is configured to search for network state information in the kernel associated with the network device, and
- wherein the network state information is maintained in the user space of the network device or in a distributed manner among multiple network devices;
- and
- providing, by the first intercept library of the network device, the first request for the subscription for the first asynchronous network state information to a service daemon, of the user space of the network device, via the first intercept socket.
