Abstract
A system includes a first device that communicates a first configuration signal, an IP address and port identifier to a second device. The second device includes a router having a quality of service module therein. The second device deep packet inspects communication signals destined for the first device based on the IP address and port identifier. The quality of service module applies a quality of service policy to the communication signals based on deep packet inspecting to form modified communication signals. The first device performs a function in response to the modified communication signals.
Claims14
A method comprising:
- communicating, from a non-deep packet inspecting first device, a first dynamic host communication signal comprising a vendor extension comprising a first flow signal description corresponding to a type of content contained in a signal flow, an IP address and port identifier to a deep packet inspecting second device, said second device comprising a router having a quality of service module therein;
- communicating a universal plug and play signal from the first device to the second device comprising a second port identifier and a second IP address;
- thereafter, identifying and deep packet inspecting, at the router of the second device, communication signals destined for the first device based on the IP address and port identifier and the second port identifier and second IP address of the universal plug and play signal;
- applying a quality of service policy to the communication signals based on inspecting to form modified communication signals based on the first flow signal description;
- communicating the modified communication signals to the first device;
- and
- performing a function at the first device in response to the modified communication signals.
A system comprising:
- a non-deep packet inspecting first device communicating a first dynamic host communication signal comprising a vendor extension comprising a first flow signal description corresponding to a type of content contained in a signal flow, an IP address and port identifier to a deep packet inspecting second device, said second device comprising a router having a quality of service module therein;
- said first device communicating a universal plug and play signal to the second device comprising a second port identifier and a second IP address;
- said second device deep packet identifying and inspecting communication signals destined for the first device based on the IP address and port identifier and the universal plug and play signal;
- said quality of service module applying a quality of service policy to the communication signals based on deep packet inspecting to form modified communication signals based on the flow signal description and communicating the modified communication signals to the first device;
- and
- said first device performing a function in response to the modified communication signals.
