An equalization optimizer (300) analyzes successive samples of at least one channel-related parameter (Pc) so as to determine contribution values of one or more time-reference classes representative of timescales of impact of channel impairments on response of an optical channel. The equalization optimizer (300) obtains environmental conditions data (Ed) representing environmental conditions at which equalization-related operations have to be performed. The equalization optimizer (300) performs channel inference so as to determine a contribution value for one or more remaining time-reference classes among said time-reference classes by relying on information learnt (Ld) from another channel in similar environmental conditions. The equalization optimizer (300) determines a value of at least one equalization-related parameter (Pe) according to the contribution values of the time-reference classes, and configures the equalization-related operations in accordance.

A method (60a) for determining assistance information for transmitting an upcoming data packet (j) via a route in a delay tolerant network including at least one contact (C₁-C₄) linking two routing entities (A-E),the method (60a) comprising:(S60) obtaining data related to the contact (C₁-C₄),(S611, S621) obtaining data related to the transmission of a data packet (i, j) among the upcoming data packet (j) and an ongoing data packet (i),based on at least said data related to the transmission of the data packet, (S612, S624) splitting the contact, said splitting resulting in at least first and second split contact (C_3a, C_3a*, C_3b, C_3b*) linking said two routing entities (A-E),(S614, S626) determining the assistance information, including at least data related to the first split contact and the second split contact (C_3a, C_3a*, C_3b, C_3b*).

An equalization optimizer analyzes (S401) successive samples of at least one channel-related parameter Pc so as to determine contribution values of time-reference classes representative of timescales of impact of channel impairments on response of an optical channel. The equalization optimizer determines (S402) a value of at least one equalization-related parameter Pe according to the contribution values of the predetermined time-reference classes and configures (S403) equalization-related operations in accordance. The equalization optimizer reviews (S404) the contribution value of each time-reference class at a rate of the timescale corresponding to the time-reference class in question, and updates (S406) accordingly the at least one equalization-related parameter Pe so that a part thereof which depends on the time-reference class in question is only updated, and the equalization optimizer reconfigures (S407) the equalization-related operations in accordance.
