Problems solved by technology

Providing improved quality of service for certain packets adds burden on network resources such that it is not usually possible to maintain the highest levels of QoS for every packet travelling through a network section.
Unfortunately, most sources of data packets (e.g. at the customer premise) cannot be trusted to assign their own priority level to packets, as it is in the best interest of each to declare a high priority.
This makes it difficult for carriers to discriminate between those packets that should truly be entitled to improved QoS and those that should not.

Embodiment Construction

[0023]FIG. 1 shows a network architecture comprising a data network 115, a server 120 and customer premise equipment at a customer premise 110. At the customer premise 110, a plurality of customer devices 130A-F are in communication with a network access component 105 that provides and regulates access to the data network 115 for the entire customer premise 110. The customer devices 130A-F may be in direct communication with the network access component 105 through local links 175 or in indirect communication with the network access component 105 through a router 140. The network access component 105 connects to the data network 115 via a network link 160.

[0024]The data network 115 can be any network of data processing equipment and can include network equipment such as routers 125 interconnected in any particular arrangement and may include the server 120, as in the example shown. For illustrative purposes, the data network 115 will be considered to be a carrier-operated data netwo...

Abstract

Provided are methods, apparatuses and systems for providing prioritized data distribution at a customer premise. A network access component may receive priority information from a trusted source, the priority information being indicative of an association between at least one identifier and a respective priority level. The network component may determine a particular identifier associated with data received from a communication entity. The network access component may determine a particular priority level associated with the data based on the particular identifier and the priority information. The network component may also prioritize at least a portion of the data on a basis of the particular priority level.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority from International Application No. not yet available, entitled “Differentiated Priority Level Communication” filed in the Canadian Receiving Office on Dec. 23, 2008 and hereby incorporated by reference herein.FIELD OF THE INVENTION[0002]The present invention relates to the field of network communication and more particularly to the field of network communication with different priority levels for different types of data.BACKGROUND[0003]Packet-based networks such as the internet tend to employ best-effort forwarding strategies whereby packets travel through the network with no particular guarantees regarding travel time or jitter. In certain instances, however, network services require or would benefit from certain guarantees or preferential treatment and systems have been developed to provide higher priority for certain packets and to guarantee certain Quality of Service (QoS) standards for these packets. P...
