    摘要: The network comprises an optical interconnection tree linking sending points of stations to a receiving point of a concentrator via access links (F1-F3), a coupling system (C) and a common optical link (OL). The stations can send optical signals (λu1, λu2, λu3) each carried by the same “uplink” wavelength (λu). Each station includes a carrier detection system able to detect the presence at its sending point (Ki) of an optical wave at said uplink wavelength (λu) that was not sent by the same station. The detection system cooperates with sending control means to inactivate sending if such presence is detected. The network further includes: an emulator (LDa, Ca, G1-G3) adapted to send auxiliary waves (λa1, λa2, λa3) at said uplink wavelength (λu) and to couple them into the access links (F1-F3) so that they propagate in the downlink propagation direction; and a control system (2a) of the emulator for selectively activating the sending of the auxiliary waves. The invention is particularly applicable to optical access or metropolitan networks.

    摘要: A packet-switched communications network (PSN) includes a multiplicity of nodes (Ni) adapted to switch streams of packets benefiting from circuit emulation services, known as CES packets. The network uses a particular method of resynchronizing the CES streams. According to that method, for a CES stream intended to take an associated path (CE) from an ingress node (N1) passing through a set of nodes including a subset of nodes adapted to resynchronize CES streams selectively, effective resynchronization of said stream by a node selected from said subset is conditioned by a value representative of the cumulative jitter suffered by said stream as far as that node.

The aforementioned optical network access node comprises means such as a hub (320) which can be used for the communication between the optical receiver (330-2) and the optical emitter (330-1). The wavelengths of the rising signals and the wavelengths of the falling signals are shared by several stations.
