摘要： A method for providing mobility of a mobile node in a packet transport network, and a packet transport network system are provided. The packet transport network system includes a plurality of gateway switches configured in a plurality of packet transport access networks to connect a packet transport core network and transmit/receive a packet to/from a certain terminal via a certain access switch. When the certain terminal moves, each gateway switch updates a tunnel mapping and management table according to the movement of the certain terminal, allocates a pre-set tunnel by using information included in the tunnel mapping and management table, and transmits/receives a packet to/from a counterpart terminal via the allocated tunnel. Thus, a packet loss and delay due to the influence of handover occurring when the mobile node moves between networks can be minimized and the handover procedure can be simplified.

摘要： An Ethernet protection switching method based on a change in link status in a link aggregation sublayer is disclosed. If an Ethernet link aggregation sublayer is present on an Ethernet connection path, a link aggregation sublayer Management Entity Group (MEG) end point is assigned to the Ethernet link aggregation sublayer to generate a link aggregation message for Ethernet connection management and protection switching. When a change in link status is detected in the Ethernet link aggregation sublayer, the link-aggregation-sublayer MEG end point generates and sends the link aggregation message to an MEG end point performing Ethernet connection management and protection switching. Adequate Ethernet protection switching may be performed even in the presence of the link aggregation sublayer.

摘要： Provided is a method of processing a packet for improving performance of an Ethernet switch. According to the present invention, a routine of searching a virtual local area network (VLAN) table by a decapsulation microblock and a bridge microblock may be performed by a core component when a core component generates tables and thus the number of memory accesses may be reduced. Also, VLAN port state information of an input port and VLAN port tagging information of an output port may be stored in metadata and may be transmitted to a next microblock. Accordingly, a duplicate memory access routine of the bridge microblock and an encapsulation microblock may be removed and thus an access time delay may be reduced, thereby improving performance of an Ethernet switch.
