Packet routing via payload inspection for quality of service management

A method, executed by a processor, for routing messages in a network, comprising:

• receiving a message having a header section, at least one subject, and a plurality of data attributes;
• retrieving the subject and the data attributes from the message;
• retrieving a subscription based upon the subject;
• determining a quality of service guarantee for the message, said quality of service guarantee is associated with a reserved bandwidth;
• applying the data attributes to the subscription in a network core in order to determine how to route the message, the subscription specifying a plurality of filters, the step of applying the data attributes, comprising:
• extracting data attributes from the payload section,
• comparing the extracted data attributes to two or more attributes filters, and
• if the comparing step indicates that each of the two or more attributes filters is satisfied, performing a set of functions;
• and
• selectively routing the message based upon the applying and the quality of service guarantee,
• wherein each attributes filter describes a set of events that a subscriber is interested in receiving from publishers.

An apparatus for routing packets in a network in conjunction with a quality of service guarantee, comprising a processor and a memory, said processor comprising:

• means for receiving a packet having a header section and a payload section;
• means for inspecting the payload section of the packet in a network core, an inspection comprising:
• extracting data attributes from the payload section,
• comparing the extracted data attributes to two or more attributes filters, and
• if the comparing step indicates that each of the two or more attributes filters is satisfied, determining how to route the packet;
• means for determining a quality of service guarantee for the packet, said quality of service guarantee is associated with a reserved bandwidth;
• and
• means for selectively routing the packet based upon the inspection results obtained from and the quality-of-service guarantees determined by the inspecting and quality of service modules above,
• wherein each attributes filter describes a set of events that a subscriber is interested in receiving from publishers.

An apparatus for routing messages in a network, comprising a processor and a memory, said processor comprising:

• means for receiving a message having a header section, at least one subject, and a plurality of data attributes;
• means for retrieving the subject and the data attributes from the message;
• means for retrieving a subscription based upon the subject, wherein the means for retrieving the subscription includes means for retrieving a plurality of filters corresponding with the subscription;
• means for matching the data attributes to the plurality of filters in a network core in order to determine how to route the message;
• and
• means for determining a quality of service guarantee for the message, said quality of service guarantee is associated with a reserved bandwidth;
• wherein each filter describes a set of events that a subscriber is interested in receiving from publishers.
