Systems disclosed herein may allocate buffer space using methods, which prevent other resource allocation methods from apportioning the other resources in a way that inhibits system needs from being met. As such, buffer space may be dynamically allocated without impeding other resource allocation by basing the buffer space allocation at least on the traffic priority class that each allocated buffer will handle. Alternatively, buffer space may be dynamically allocated without impeding other resource allocation by basing the buffer space allocation at least on the bandwidth needs of each respective buffer being allocated. Alternatively still, buffer space may be dynamically allocated without impeding other resource allocation by basing the buffer space allocation at least on a function of the traffic priority class that each allocated buffer will handle and the bandwidth needs of each respective buffer being allocated.
