Title
(EN) Priority-sensitive reallocation of buffer space
Abstract
(EN)
The invention proposes a priority-sensitive reallocation of buffer space shared among multiple ports. When reallocating, a share of buffer space allocated to one port is reduced by emptying occupied buffer space. The emptying of occupied 10 buffer space is performed in accordance with traffic priorities. Upon emptying the buffer space is reallocated to another port. The present invention allows for improved processing of quality of service traffic in systems with dynamic allocation of buffer space.
