using the one or more processors, determining, for each publisher computer system of the plurality of publisher computer systems, a ratio of the actual rate of updates and the publisher limit rate;

using the one or more processors, whenever the ratio is less than a threshold ratio, assigning to the publisher computer system, an updated publisher limit rate that is less than the offered rate of updates.

3. The subscriber computer system of claim 1 , further comprising instructions which when executed cause:

using the one or more processors, receiving, from each of the publisher computer systems of the plurality of publisher computer systems, one or more updates over a period of time;

using the one or more processors, determining, for each publisher computer system of the plurality of publisher computer systems, an actual rate of updates;

using the one or more processors, determining, for each publisher computer system of the plurality of publisher computer systems, a ratio of the actual rate of updates and the publisher limit rate;

using the one or more processors, whenever the ratio is greater than a threshold ratio, assigning to the publisher computer system, an updated publisher limit rate that is upper bounded by a maximum increase in the publisher limit rate.

4. The subscriber computer system of claim 1 , further comprising instructions which when executed cause:

using the one or more processors, sending to a publisher computer system of the plurality of publisher computer systems, an instantaneous publisher limit rate of zero.

5. The subscriber computer system of claim 1 , further comprising instructions which when executed cause:

using the one or more processors, determining, for each publisher computer system of the plurality of publisher computer systems, an available network bandwidth associated with the publisher computer system;

wherein the publisher limit rate of the publisher computer system is assigned using the available network bandwidth associated with the publisher computer system.

6. The subscriber computer system of claim 1 , further comprising instructions which when executed cause:

using the one or more processors, determining, for each publisher computer system of the plurality of publisher computer systems, a quality of service (QoS) class level of the publisher computer system;

wherein the publisher limit rate of the publisher computer system is assigned using the QoS class level of the publisher computer system.

7. A resource allocation method providing an improvement in control of rates at which a plurality of publisher computer systems send digital electronic update messages to the subscriber computer system comprising:

using one or more processors, determining for a subscriber computer system a subscriber limit rate at which the subscriber computer system can process updates received from a plurality of publisher computer systems, and storing the subscriber limit rate in computer memory, wherein each of the updates comprises an electronic digital message received over a computer network;

using the one or more processors, determining, for each publisher computer system of the plurality of publisher computer systems, an offered rate of updates sent to the subscriber computer system and storing a plurality of the offered rates in the computer;

using the one or more processors, determining, for each publisher computer system of the plurality of publisher computer systems, a utility of updates sent by the publisher computer system and storing a plurality of the utilities in the computer memory, each utility that is associated with a publisher computer comprising a combination of a difference between a current value of a data element and a previous value of the data element, a first value set to indicate that the data element was created and that a previous update indicated it had been removed, and a second value set to indicate that the data element was removed and that the previous update indicated that it existed;

using the one or more processors, determining, for each publisher computer system of the plurality of publisher computer systems, a priority level of the publisher computer system in relation to other publisher computer systems of the plurality of publisher computer systems,

using the one or more processors, assigning to each publisher computer system of the plurality of publisher computer systems a publisher limit rate at which the respective publisher computer system sends updates to the subscriber computer system using the offered rate, the utility of updates of the respective publisher computer system, and the priority level of the publisher computer system.

8. The resource allocation method of claim 7 , further comprising:

using the one or more processors, receiving, from each of the publisher computer systems of the plurality of publisher computer systems, one or more updates over a period of time;

using the one or more processors, determining, for each publisher computer system of the plurality of publisher computer systems, an actual rate of updates;

using the one or more processors, determining, for each publisher computer system of the plurality of publisher computer systems, a ratio of the actual rate of updates and the publisher limit rate;

using the one or more processors, whenever the ratio is less than a threshold ratio, assigning to the publisher computer system, an updated publisher limit rate that is less than the offered rate of updates.

9. The resource allocation method of claim 7 , further comprising:

using the one or more processors, receiving, from each of the publisher computer systems of the plurality of publisher computer systems, one or more updates over a period of time;

using the one or more processors, determining, for each publisher computer system of the plurality of publisher computer systems, an actual rate of updates;

using the one or more processors, determining, for each publisher computer system of the plurality of publisher computer systems, a ratio of the actual rate of updates and the publisher limit rate;

using the one or more processors, whenever the ratio is greater than a threshold ratio, assigning to the publisher computer system, an updated publisher limit rate that is upper bounded by a maximum increase in the publisher limit rate.

10. The resource allocation method of claim 7 , further comprising:

using the one or more processors, sending to a publisher computer system of the plurality of publisher computer systems, an instantaneous publisher limit rate of zero.

11. The resource allocation method of claim 7 , further comprising:

using the one or more processors, determining, for each publisher computer system of the plurality of publisher computer systems, an available network bandwidth associated with the publisher computer system;

wherein the publisher limit rate of the publisher computer system is assigned using the available network bandwidth associated with the publisher computer system.

12. The resource allocation method of claim 7 , further comprising:

using the one or more processors, determining, for each publisher computer system of the plurality of publisher computer systems, a quality of service (QoS) class level of the publisher computer system;
