A method, computer program product, and system of managing multicast groups for distribution of multicast content to a plurality of targets are provided. Managing multicast groups includes receiving a plurality of requests to join a multicast group sent by the plurality of targets and evaluating from the plurality of requests a resource utilization required for each of the plurality of targets. Managing multicast groups further includes generating the multicast group by accepting targets of the plurality of targets; accumulating each resource utilization corresponding to each accepted target into an accumulated resource utilization; and closing, by the processor, the multicast group when the accumulated resource utilization of the accepted targets exceeds a group resource utilization limit.

1. A method for managing multicast groups for distribution of multicast content to a plurality of targets, comprising: receiving, by a processor coupled to a memory, a plurality of requests to join a multicast group sent by the plurality of targets;evaluating, by the processor, from the plurality of requests a resource utilization required for each of the plurality of targets;generating, by the processor, the multicast group by accepting targets of the plurality of targets;accumulating, by the processor, each resource utilization corresponding to each accepted target into an accumulated resource utilization;closing, by the processor, the multicast group when the accumulated resource utilization of the accepted targets exceeds a group resource utilization limit; andgenerating a second multicast group beginning with a target that causes the accumulated resource utilization to exceed the group resource utilization limit. 2. The method of claim 1, further comprising closing the multicast group when the accumulated resource utilization of the accepted targets is less than the group resource utilization limit and a predefined time cutoff is reached. 3. The method of claim 1, further comprising defining the group resource utilization limit at a first instance based on environment conditions at a time of creating the multicast group. 4. The method of claim 3, further comprising varying the group resource utilization limit based on environment conditions at a time subsequent to creating the multicast group. 5. The method of claim 3, where the environment conditions include an available bandwidth and computing resources. 6. The method of claim 1, further comprising placing late joining targets in a queue while the multicast group is generated. 7. Repeating the method of claim 1 to satisfy a remaining set of the plurality of requests. 8. A computer program product, the computer program product comprising a non-transitory computer readable storage medium having program instructions for managing multicast groups for distribution of multicast content to a plurality of targets embodied therewith, the program instructions executable by a processor to cause the processor to perform: receiving a plurality of requests to join a multicast group sent by the plurality of targets;evaluating from the plurality of requests a resource utilization required for each of the plurality of targets;generating the multicast group by accepting targets of the plurality of targets;accumulating each resource utilization corresponding to each accepted target into an accumulated resource utilization;closing the multicast group when the accumulated resource utilization of the accepted targets exceeds a group resource utilization limit; andgenerating a second multicast group beginning with a target that causes the accumulated resource utilization to exceed the group resource utilization limit. 9. The computer program product of claim 8, the program instructions executable to further cause the processor to perform: closing the multicast group when the accumulated resource utilization of the accepted targets is less than the group resource utilization limit and a predefined time cutoff is reached. 10. The computer program product of claim 8, the program instructions executable to further cause the processor to perform: defining the group resource utilization limit at a first instance based on environment conditions at a time of creating the multicast group. 11. The computer program product of claim 10, the program instructions executable to further cause the processor to perform: varying the group resource utilization limit based on environment conditions at a time subsequent to creating the multicast group. 12. The computer program product of claim 10, wherein the environment conditions include an available bandwidth and computing resources. 13. The computer program product of claim 8, the program instructions executable to further cause the processor to perform: placing late joining targets in a queue while the multicast group is generated. 14. The computer program product of claim 10, wherein the program instructions are repeatedly executed to further cause the processor to satisfy a remaining set of the plurality of requests. 15. A system, comprising: a memory having computer readable instructions for managing multicast groups for distribution of multicast content to a plurality of targets embodied therewith; anda processor for executing the computer readable instructions, to cause the system to perform:receiving a plurality of requests to join a multicast group sent by the plurality of targets;evaluating from the plurality of requests a resource utilization required for each of the plurality of targets;generating the multicast group by accepting targets of the plurality of targets;accumulating each resource utilization corresponding to each accepted target into an accumulated resource utilization;closing the multicast group when the accumulated resource utilization of the accepted targets exceeds a group resource utilization limit; andgenerating a second multicast group beginning with a target that causes the accumulated resource utilization to exceed the group resource utilization limit. 16. The system of claim 15, the program instructions executable to further cause the system to perform: closing the multicast group when the accumulated resource utilization of the accepted targets is less than the group resource utilization limit and a predefined time cutoff is reached. 17. The system of claim 15, the program instructions executable to further cause the system to perform: defining the group resource utilization limit at a first instance based on environment conditions at a time of creating the multicast group. 18.
