Abstract
In a wide area network arrangement composed of some number of secure local networks and an Internet service provider (ISP) back-bone, LAN hosts are able to indirectly access network routers, through an ISP quality of service (QoS) module, to request that information transmitted during certain specified sessions be given priority treatment by the network.
Claims20
A method comprising:
- receiving, at a quality of service (QoS) module from an originating router, a session request for establishing a QoS session for transmitting information from the originating router to a destination router, the originating and destination routers being Internet Protocol (IP) routers;
- sending, from the QoS modules, a message to the originating router in response to the session request, the message including a request to reserve resources at the originating router for transmitting the information according to parameters of the QoS session;
- and
- setting up, by the QoS module, the QoS session on the transmission path between the originating and destination routers in accordance with the session request if the resources are available and reserved at the originating router;
- wherein the QoS module is located at a QoS hosting site of a Wide Area Network (WAN) that is communicably coupled to the originating and destination routers.

A network, comprising:
- an originating router coupled to a host in a first local area network, the originating router being an Internet Protocol (IP) router;
- a destination router coupled to another host in a second local area network, the destination router being an IP router;
- and
- a quality of service (QoS) module at a QoS hosting site of a Wide Area Network (WAN) communicably coupled to the originating router and the destination router to:
- receive a session request for establishing a QoS session for transmitting information from the originating router to the destination router;
- send a message to the originating router in response to the session request, the message including a request to reserve resources at the originating router for transmitting the information according to parameters of the QoS session;
- and
- set up the QoS session on the transmission path between the originating and destination routers in accordance with the session request if the resources are available and reserved at the originating router.
5 more elements
An article of manufacture, comprising a computer-readable medium storing instructions that, when accessed by a computer, cause the computer to execute operations comprising:
- receiving, at a quality of service (QoS) module from an originating router, a session request for establishing a QoS session for transmitting information from the originating router to a destination router, the originating and destination routers being Internet Protocol (IP) routers;
- sending, from the QoS modules, a message to the originating router in response to the session request, the message including a request to reserve resources at the originating router for transmitting the information according to parameters of the QoS session;
- and
- setting up, by the QoS module, the QoS session on the transmission path between the originating and destination routers in accordance with the session request if the resources are available and reserved at the originating router;
- wherein the QoS module is located at a QoS hosting site of a Wide Area Network (WAN) that is communicably coupled to the originating and destination routers.
