A first node of a wireless network comprising a radio access network and an enhanced packet core, said first node being adapted to manage user-plane of a plurality of bearers (Br) established for ingress flow from a second node of said wireless network to said first node, said first node comprising a first processor, a front-end processor and a plurality of end-point unit processors (PR2, PR2', PR2", PR2'''): - said first processor being adapted to: ∘ define subsets of contiguous tunnel endpoint identifiers within a set of tunnel endpoint identifiers; ∘ allocate a subset of contiguous tunnel endpoint identifiers to each end-point unit processor (PR2, PR2', PR2", PR2''') to define a virtual path for said ingress flow by means of at least one bit of the contiguous tunnel endpoint identifiers; o chose a tunnel endpoint identifier within a subset and send said tunnel endpoint identifier to said second node for a bearer (Br) to be established for said ingress flow from said second node to said first node; ∘ signal said tunnel endpoint identifier chosen to the corresponding end-point unit processor (PR2, PR2', PR2", PR2'''). - said front-end processor being adapted to: ∘ receive the user-plane from said second node through the bearer for which said tunnel endpoint identifier has been chosen; ∘ route the user-plane of said bearer to an end-point unit processor (PR2, PR2', PR2", PR2''') through the virtual path corresponding to the subset comprising said tunnel endpoint identifier; - said end-point unit processors (PR2, PR2', PR2", PR2''') being adapted to process the user-plane received from said front-end processor. - said first processor being adapted to: ∘ define subsets of contiguous tunnel endpoint identifiers within a set of tunnel endpoint identifiers; ∘ allocate a subset of contiguous tunnel endpoint identifiers to each end-point unit processor (PR2, PR2', PR2", PR2''') to define a virtual path for said ingress flow by means of at least one bit of the contiguous tunnel endpoint identifiers; o chose a tunnel endpoint identifier within a subset and send said tunnel endpoint identifier to said second node for a bearer (Br) to be established for said ingress flow from said second node to said first node; ∘ signal said tunnel endpoint identifier chosen to the corresponding end-point unit processor (PR2, PR2', PR2", PR2'''). ∘ define subsets of contiguous tunnel endpoint identifiers within a set of tunnel endpoint identifiers; ∘ allocate a subset of contiguous tunnel endpoint identifiers to each end-point unit processor (PR2, PR2', PR2", PR2''') to define a virtual path for said ingress flow by means of at least one bit of the contiguous tunnel endpoint identifiers; o chose a tunnel endpoint identifier within a subset and send said tunnel endpoint identifier to said second node for a bearer (Br) to be established for said ingress flow from said second node to said first node; ∘ signal said tunnel endpoint identifier chosen to the corresponding end-point unit processor (PR2, PR2', PR2", PR2'''). - said front-end processor being adapted to: ∘ receive the user-plane from said second node through the bearer for which said tunnel endpoint identifier has been chosen; ∘ route the user-plane of said bearer to an end-point unit processor (PR2, PR2', PR2", PR2''') through the virtual path corresponding to the subset comprising said tunnel endpoint identifier; ∘ receive the user-plane from said second node through the bearer for which said tunnel endpoint identifier has been chosen; ∘ route the user-plane of said bearer to an end-point unit processor (PR2, PR2', PR2", PR2''') through the virtual path corresponding to the subset comprising said tunnel endpoint identifier; - said end-point unit processors (PR2, PR2', PR2", PR2''') being adapted to process the user-plane received from said front-end processor.
