Definitions

  • GFP defines two types of frames: GFP client frames and GFP control frames.
  • customer frames are available in both customer data frames and customer management frames.
  • the client data frame is set to transmit the client signal
  • the management frame is set to transmit management information related to the client signal or GFP connection.
  • GFP also provides a flexible payload extension header mechanism.
  • GFP can be applied in transport network elements, such as SDH, OTN, or in data network elements such as IP routers and Ethernet switches.
  • transport network elements such as SDH, OTN, or in data network elements such as IP routers and Ethernet switches.
  • SDH transport network elements
  • GFP has become a mainstream encapsulation technology.
  • the MSTP is an SDH-based multi-service delivery platform, and the Ethernet service is encapsulated into GFP through EoS (Ethernet over SDH) technology. It is convenient to realize the interconnection and intercommunication of equipments of various manufacturers.
  • the primary site sends the GFP client management frame to a designated site connected to the primary site, or the secondary site sends the GFP to a designated site connected to the secondary site.
  • the method includes: the designated site continues to send the GFP client management frame to a site connected to the designated site.
  • FIG. 4 is a schematic structural diagram of a GFP client frame according to an alternative embodiment of the present invention.
  • FIG. 1 is a flowchart of a method for protecting an Ethernet ring network according to an embodiment of the present invention. As shown in FIG. 1 , the process includes the following steps:
  • the first data frame carries identifier information that is set to indicate the primary site.
  • the slave port is set to receive the GFP Ethernet data frame, and the primary station determines whether the received GFP Ethernet data frame contains the identifier of the local station, and if so, blocks the slave port service; if not, the slave port is opened.
  • the slave port is in the forwarding state, and the other party identifier that is received by the master port and smaller than the value of the site identifier is added to the GFP frame extension header, so that when the slave port is disconnected, the slave port can always be enabled. One ring in which the port is located is disconnected.
  • Step S602 The network management system sends a ring network configuration to each site;
  • each site port After receiving the client management frame, each site port deletes the MAC address table of the port, and the slave station also forwards the client management frame to the remaining ports.
  • the final customer management frame is transmitted to each site in the network and terminated at the primary site.

Abstract

L'invention concerne un procédé et un dispositif de protection de réseau en anneau Ethernet, le procédé comprenant les étapes suivantes : une station maîtresse dans le réseau en anneau Ethernet transmet une première trame de données à une station esclave par l'intermédiaire d'un port maître de la station maîtresse, la première trame de données transportant des informations d'identification configurées pour indiquer la station maîtresse ; la station maîtresse reçoit une seconde trame de données à partir d'un port esclave, la seconde trame de données étant transmise par la station esclave en réponse à la première trame de données ; la station maîtresse détecte que la seconde trame de données ne contient pas les informations d'identification. La présente invention traite le problème de la complexité des contenus et des difficultés de la maintenance dans le procédé de protection de réseau en anneau Ethernet suite à la génération d'un protocole d'arbre dans l'art connexe, améliorant ainsi encore le taux de commutation de protection de réseau en anneau.
