Centralized configuration with dynamic distributed address management

摘要

The present disclosure discloses a network device and/or method for centralized configuration with dynamic distributed address management. The disclosed network device receives, at a first network node, a range of sub network addresses and a specified size for a sub network. The disclosed network device then divides the range of sub network addresses into a plurality of sub-ranges of sub network addresses based on the specified size. Further, the network device allocates the plurality of sub-ranges of sub network addresses to a plurality of sub networks, and transmits an allocated sub-range of sub network addresses to a corresponding sub network at a second network node through an established secure communication channel. Moreover, the network device can retrieve a profile template that includes the range of sub network addresses and the specified size of the sub network; and create a profile based on the profile template.

1. A computer implemented method, comprising:
receiving, at a remote network device connected to a remote network node, a network address for a remote node controller at a central network node; establishing a secure communication channel between the remote network device and the remote node controller over a public network, wherein establishing includes using the network address for the remote node controller, wherein establishing includes establishing an encapsulation tunnel between the remote network device and the central network node, wherein network traffic between the remote network node and the central network node is routed through the encapsulation tunnel, and wherein the encapsulation tunnel facilitates creation of a LaYer-2 network that extends across the remote network node and the central network node; receiving a network configuration for the remote network node over the secure communication channel, wherein the network configuration includes a network address allocation for the remote network device and a set of network addresses for dynamically allocating to devices connected to the remote network node, wherein the set of network addresses correspond to central network node routable addresses, and wherein the received network configuration facilitates continued functioning of the remote network node when the remote node controller at the central network node is unreachable from the remote network node, and wherein network addresses from the set of network addresses are dynamically allocated when the remote node controller at the central network node is unreachable from the remote network node; determining a subset of network addresses of the set of network addresses to reserve for a sub-network connected to the remote network node; and transmitting a sub-network profile to the sub-network, wherein the sub-network profile includes the subset of network addresses, and wherein receiving the sub-network profile at a sub-network access point facilitates allocation of one address of the subset of network addresses to the sub-network access point and reservation of remaining addresses of the subset of network addresses for dynamic allocation.
