A network device obtains a data package associated with an ISSU procedure and determines, based on the data package, that a control plane of the network device is to be rebooted to facilitate performance of the ISSU procedure. The network device causes, based on determining that the control plane is to be rebooted, a plurality of applications of the network device to stop executing on the network device and a control plane state of the network device to be frozen. The network device then causes the ISSU procedure to be performed. The network causes, based on causing the ISSU procedure to be performed, the control plane state of the network device to be restored and the plurality of applications to resume executing on the network device.

Hitless upgrade of a network device

A first system manager operating on a first node of a distributed computing system, receives data indicating a current state of the distributed computing system. The first system manager may determine, based at least in part on the current state of the distributed computing system and a set of rules for an application, an updated state of the distributed computing system. Furthermore, the first node may send the updated state of the distributed computing system to a second node of the distributed computing system. Responsive to receiving the updated state of the distributed computing system, a second system manager on the second node may modify a state of the second node. Modifying the state of the second node may comprise at least one of: starting the application on the second node, stopping the application on the second node, or modifying a state of the application on the second node.

Policy based framework for application management in distributed systems

A first system manager operating on a first node of a distributed routing system, receives data indicating a current state of the distributed routing system. The first system manager may determine, based at least in part on the current state of the distributed routing system and a set of rules for an application, an updated state of the distributed routing system. Furthermore, the first node may send the updated state of the distributed routing system to a second node of the distributed routing system. Responsive to receiving the updated state of the distributed routing system, a second system manager on the second node may modify a state of the second node. Modifying the state of the second node may comprise at least one of: starting the application on the second node, stopping the application on the second node, or modifying a state of the application on the second node.
