NETWORK SEGMENTATION USING REGIONS
Segmenting personal area networks (PAN) in a computer network using regions, which may include: associating a first client device to a first PAN, where the first PAN is assigned to a first region from a plurality of regions; receiving an indication that the first client device is in communication with a first computer networking device; identifying whether the first computer networking device is a member of a plurality of computer networking devices that service the first region; selecting one of a first identifier or a second identifier based on whether the first computer networking device is or is not a member of the plurality of computer networking devices; and communicating the selected one of the first identifier and the second identifier to the first computer networking device. The first computer networking device may be configured to tag PAN network traffic from the first client device using the provided identifier.
1 . A method comprising:
establishing a wireless connection between an access point and a client device, where the access point is configured to service a first region from a plurality of regions;
identifying, by the access point, that the client device is a member of a first personal area network (PAN) associated with a second region from the plurality of regions;
establishing, by the access point and in response to the identifying, a network tunnel between the access point and a gateway device; and
communicating first PAN traffic for the client device via the established network tunnel.
2 . The method of claim 1 , wherein the access point is configured to identify that the client device is a member of the first PAN based on a message received from an authentication and authorization server.
3 . The method of claim 2 , wherein the message is an access acceptance message indicating that the client device is authorized to access a network via the access point.
4 . The method of claim 2 , wherein the message includes an identifier, and wherein the access point is configured to associate the first PAN traffic with the identifier.
5 . The method of claim 4 , wherein the access point is configured to encapsulate the first PAN traffic in a data unit that comprises the identifier.
6 . The method of claim 4 , wherein the identifier is a virtual network identifier (VNI).
7 . A method comprising:
associating a first client device with a first personal area network (PAN), wherein the first PAN is assigned to a first region from a plurality of regions;
detecting that the first client device is in communication with a computer networking device that services a second region from the plurality of regions;
establishing a tunnel between the computer networking device that services the second region and a network edge device; and
transmitting, via the established tunnel, first PAN network traffic received at the network edge device and directed to the first client device.
8 . The method of claim 7 , further comprising transmitting, via the established tunnel, second PAN network traffic received at the computer networking device and directed to a second client device associated with the first PAN.
9 . The method of claim 7 , wherein the computer networking device is configured to establish the tunnel with the network edge device based on a message received from an authentication and authorization server.
10 . The method of claim 9 , wherein the message is an access acceptance message indicating that the first client device is authorized to access a network via the computer networking device.
11 . The method of claim 9 , wherein the message includes an identifier, and wherein the computer networking device is configured to associate the first PAN traffic with the identifier.
12 . The method of claim 7 , wherein the computer networking device is an access point.
13 . The method of claim 7 , wherein the established tunnel has a timeout period lasting at least one week.
14 . A method comprising:
associating a first client device to a first personal area network (PAN), wherein the first PAN is assigned to a first region from a plurality of regions;
receiving an indication that the first client device is in communication with a first computer networking device;
identifying whether the first computer networking device is a member of a plurality of computer networking devices that service the first region;
selecting one of a first identifier or a second identifier, wherein the first identifier is selected in response to identifying that the first computer networking device is a member of the plurality of computer networking devices, and wherein the second identifier is selected in response to identifying that the first computer networking device provides service to a second region different than the first region; and
communicating the selected one of the first identifier and the second identifier to the first computer networking device, wherein the first computer networking device is configured to tag PAN network traffic from the first client device using the communicated selected one of the first identifier and the second identifier.
15 . The method of claim 14 , wherein the first identifier is a virtual local area network (VLAN) identifier, and the second identifier is a virtual network identifier (VNI).
16 . The method of claim 14 , wherein the first computer networking device is an access point.
17 . The method of claim 14 , wherein the first computer networking device is a networking switch.
18 . The method of claim 14 , wherein the selected one of the first identifier and the second identifier is communicated in an authorization access message indicating that the first client device is authorized to access a network via the first computer networking device.
