Similar to VRF (virtual routing and forwarding instance) maintained in IP/MPLS routers to deliver layer 3 VPNs, IP VPNs, IP/MPLS switches maintain a Virtual Switching Instance (VSI) to deliver layer 2 VPNs, using VPLS.
The present disclosure provides hybrid packet-optical private network systems and methods for a private and dedicated multi-point Ethernet Private Local Area Network (EPLAN). The network systems and methods include a Layer 1 infrastructure service with the inclusion of reserved, dedicated packet switch capacity upon which clients can build their personal, private packet networks. In the systems and methods described herein, packet networking methods are not used to partition the isolated LAN connectivity. Instead, dedicated Ethernet Private LANs (EPLs) are defined between dedicated virtual switching instances (VSIs) that are defined, as necessary, within larger packet-optical switches. Each VSI is partitioned from the remainder of its packet switch fabric as a dedicated, private resource for a specific EPLAN. A packet network is then built by the customer on top of the private EPLAN bandwidth and operated as an isolated, private network with no influence by other carrier's network resources.
The invention provides a message forwarding method and device. The method comprises the following steps: recording a flow switching flow table entry in an effective state written by a controller in a flow table; wherein a matching domain field of the flow switching flow table entry is a DR interface, and an instruction field of the flow switching flow table entry is sent through a VXLAN tunnel connected with neighbor distributed elastic DR equipment; searching an MAC address table item matched with a destination MAC address of the Ethernet data message to be forwarded in an MAC address table of the virtual exchange instance; searching an output port of an access link of the MAC address table entry as a local DR interface; and matching a flow switching flow table item based on the local DR interface in the flow table, packaging the Ethernet data message to be forwarded according to the packaging information of the VXLAN tunnel, and sending the Ethernet data message to the neighbor DR equipment through an output port of the VXLAN tunnel.
