mDNS support in unified access networks
Methods, systems and computer readable media for mDNS support in unified access networks are described.
1. A method for processing a service discovery request message, the method comprising:
monitoring, at a first switch, the service discovery request message and responses to determine available services from a second switch using a synced service record, wherein the first switch and the second switch are peer switches and are in different virtual local area networks (VLANs);
sending a copy of the available services to a wireless controller;
detecting, at the first switch, a service discovery request;
sending the service discovery request message from the first switch to the wireless controller requesting the available services;
receiving a response from the wireless controller;
determining a policy associated with the available services, wherein the policy is stored in a policy table at the first switch;
framing the response in a service request protocol format; and
based on the determined policy, relaying the available services in the framed response to other switches in a network, wherein the first switch and the other switches are in the same VLAN.
2. The method of claim 1 , wherein the service discovery request message is a multicast Domain Name System (mDNS) message.
3. The method of claim 1 , wherein sending the framed response comprises sending the framed response via a unicast message.
4. The method of claim 1 , wherein the first switch comprises an access point.
5. The method of claim 1 , wherein the first switch comprises a gateway switch.
6. The method of claim 1 , wherein sending the framed response comprises determining, based on end user privileges, whether to send the framed response to the network.
7. A system for processing a service discovery request message, the system comprising control circuitry configured to:
monitor, at a first switch, the service discovery request message and responses to determine available services from a second switch using a synced service record, wherein the first switch and the second switch are peer switches and are in different virtual local area networks (VLANs);
send a copy of the available services to a wireless controller;
detect, at the first switch, a service discovery request;
send the service discovery request message from the first switch to the wireless controller requesting the available services;
receive a response from the wireless controller;
determine a policy associated with the available services, wherein the policy is stored in a policy table at the first switch;
frame the response in a service request protocol format; and
based on the determined policy, relay the available services in the framed response to other switches in a network, wherein the first switch and the other switches are in the same VLAN.
8. The system of claim 7 , wherein the service discovery request message is a multicast Domain Name System (mDNS) message.
9. The system of claim 7 , wherein the control circuitry is configured to send the framed response via a unicast message.
10. The system of claim 7 , wherein the first switch comprises an access point.
11. The system of claim 7 , wherein the first switch comprises a gateway switch.
12. The system of claim 7 , wherein to send the framed response, the control circuitry is further configured to determine, based on end user privileges, whether to send the framed response to the network.
13. A non-transitory computer-readable medium having instructions stored thereon that, when executed by a processor, causes the processor to perform operations comprising:
monitoring, at a first switch, a service discovery request message and responses to determine available services from a second switch using a synced service record, wherein the first switch and the second switch are peer switches and are in different virtual local area networks (VLANs);
sending a copy of the available services to a wireless controller;
detecting, at the first switch, a service discovery request;
sending the service discovery request message from the first switch to the wireless controller requesting the available services;
receiving a response from the wireless controller;
determining a policy associated with the available services, wherein the policy is stored in a policy table at the first switch;
framing the response in a service request protocol format; and
based on the determined policy, relaying the available services in the framed response to other switches in a network, wherein the first switch and the other switches are in the same VLAN.
14. The non-transitory computer-readable medium of claim 13 , wherein the service discovery request message is a multicast Domain Name System (mDNS) message.
15. The non-transitory computer-readable medium of claim 13 , wherein for sending the framed response, the operations further comprise sending the framed response via a unicast message.
16. The non-transitory computer-readable medium of claim 13 , wherein the first switch comprises an access point.
17. The non-transitory computer-readable medium of claim 13 , wherein the first switch comprises a gateway switch.
18. The non-transitory computer-readable medium of claim 13 , wherein for sending the framed response, the operations further comprise determining, based on end user privileges, whether to send the framed response to the network.
