Abstract
A plurality of networking nodes provides a wireless network fabric that serves at least two devices. Each networking node stores global communication topology information for the wireless network fabric. One of the networking nodes performs global fabric management functions to maintain a communication channel among the at least two devices, and is responsive to a triggering event to identify a next global fabric manager from the other networking nodes. Upon detection of an attack, the global fabric management responsibilities migrate from the networking node to the next global fabric manager while maintaining connectivity between the at least two devices.
Claims20
A networking node in a network fabric of networking nodes interconnected with each other through physical links;
- wherein the networking nodes include a plurality of wireless access points, each access point configured to allow a first wireless device to exchange data with a second wireless device through the network fabric, the networking node comprising:
- at least one physical port through which data packets are communicated with other networking nodes;
- and
- a network fabric manager configured to establish a network topology among the networking nodes;
- maintain a communication channel over the network topology between the first wireless device and the second wireless device regardless of relative movement with respect to the networking nodes;
- and migrate the network fabric manager to a different networking node while retaining connectivity.
In a networking node in a network fabric of networking nodes interconnected with each other through physical links, wherein the networking nodes include a plurality of wireless access points, each access point configured to allow a first wireless device to exchange data with a second wireless device through the network fabric, a non-transitory computer readable memory storing software instructions that cause, via execution, at least one processor to operate as a network fabric manager configured to at least:
- establish a network topology among the networking nodes;
- maintain a communication channel over the network topology between the first wireless device and the second wireless device regardless of relative movement with respect to the networking nodes;
- and
- migrate operations of the network fabric manager to a different networking node while retaining connectivity.
A method of operating a networking node in a network fabric of networking nodes interconnected with each other through physical links, wherein the networking nodes include a plurality of wireless access points, each access point configured to allow a first wireless device to exchange data with a second wireless device through the network fabric, the method comprising:
- establishing a network topology among the networking nodes;
- maintaining a communication channel over the network topology between the first wireless device and the second wireless device regardless of relative movement with respect to the networking nodes;
- and
- migrating operations of the network fabric manager to a different networking node while retaining connectivity.
