The split up of data using Reservation-based Medium Access Conthel (resourceises the resource allocation requests according to the data type.
A resource controller (one for each linecard), collects the resource allocation requests from the different slices using the resources it controls and determines the allocations based on the available capacities of the resources.
The resource controller (for line-card or SF) receives resource allocations requests from slice controllers and then determines the allocated resources to the slices according to the available resources.
Using the target performance of the current control interval, it estimates the new optimal resource allocations requested by the slice to meet its performance.
The strategy of packet scheduling, resource allocation, and segment request can be obtained in our new framework.
If the total requested resource allocation is less than the available capacity, the controller satisfies all the requests and then partitions the remaining extra capacity proportionally to the requests taking into consideration the slice priority weight (w_{s}).
On one hand, in order to ensure the user experience of resource requesting, the system has to achieve fast resource allocation to timely process resource requests; on the other hand, in order to ensure the efficiency of resource allocation, how to allocate multi-dimensional resource requests to servers needs to be optimized, such that server's resource utilization can be improved.
(xr_{s,r,c}) is the total allocation request of resource type (r) in card (c) by slice (s), (0 le xr_{s,r,c} le 1).
It is the sum of the resource allocation time for the VM request, and the time to power on the VM to get it ready for use.
Slice controllers receive the performances of the slices they control from the monitors, compare them with their desired (target) performance and then generate a request for resource allocation to the respective card controllers.
The InP then simply applies a component-wise maximum (cmax) of the multiset representing all resource allocation state for a given VN request, V N b i, E a j b i = { C ( E a j k ) : ∀ EmbeddingId k ∈ V N b i } and reserves those resources.
