Problems solved by technology

[0005] However, when the vSwitch is added to the CB device as a PEX device, the CB device cannot effectively manage the user-side port on the vSwitch (also known as the OVS port, which is referred to as the OVS port in this application). The reason is: the OVS port on the vSwitch The port is not pre-fixed like a physical device. The OVS port on the vSwitch will only be created when the connected virtual machine (VM) goes online, and will be deleted when the connected VM is offline or migrated, so dynamic The change caused the CB device to fail to manage the OVS port on the vSwitch

Embodiment 1

[0087] see Figure 7 , Figure 7 A schematic diagram of Embodiment 1 of packet forwarding provided by the present invention. exist Figure 7 in, based on figure 2 or image 3 As shown, the OVS port Port7_1 connected to VM7_1 and the OVS port Port7_2 connected to VM7_2 are created on PEX device 7_1, and the OVS port Port7_3 connected to VM7_3 and OVS port Port7_4 connected to VM7_4 are created on PEX device 7_2.

[0088] The logical port Port0_1 with the E-CID of 0x3000 on the CB device is bound to Port7_1 on the PEX device 1, the logical port Port0_2 with the E-CID of 0x3001 on the CB device is bound to Port7_2 on the PEX device 1, and the E-CID on the CB device is The logical port Port0_3 of 0x4000 is bound to Port7_3 of PEX device 2, and the logical port Port0_4 of E-CID of CB device is 0x4001 is bound to Port7_4 of PEX device 2.

[0089] The network-side port Port1_0 on the PEX device 7_1 establishes an uplink (Uplink) with the CB device, and the network-side port Por...

Embodiment 2

[0113] see Figure 8 , Figure 8 The schematic diagram of embodiment 1 provided for the present invention. exist Figure 8 in, based on figure 2 or image 3 As shown, OVS port Port8_1 on PEX device 8_1 is connected to VM8_1, and OVS port Port8_2 is connected to VM8_2.

[0114] The logical port Port0_8_1 with the E-CID of 0x3000 on the CB device is bound to Port8_1 on the PEX device 8_1, and the logical port Port0_8_2 with the E-CID of 0x3001 on the CB device is bound to Port8_2 on the PEX device 8_1.

[0115] The PEX device 8_1 establishes an uplink connection (Uplink) with the CB device through Port1.

[0116] by Figure 8 The VM8_1 shown in the example sends a packet to access VM8_2. The interface IP address of VM8_1 is 192.168.1.5 and the MAC address is 00-00-00-00-00-05. The IP address of the interface of VM8_2 is 192.168.1.6 and the MAC address is 00-00-00-00-00-06. but,

[0117] VM8_1 sends a packet to access VM8_2. For ease of description, the message is reco...

Abstract

The invention provides a port extension method and apparatus. According to the port extension method and apparatus, an OVS port used for accessing a VM and extended from vSwitch as a PEX device and a logic port, bound with the OVS port, on a CB device can be flexibly and effectively configured and managed along with state changes, such as network connection, network disconnection, migration and the like, of the VM in the field of virtualization, so that the network demands of the VM in various conditions are met.

Description

technical field [0001] The present application relates to network communication technology, in particular to a port expansion method and device. Background technique [0002] Port extension technology is a vertical network integration virtualization technology that can improve network access capabilities and network management efficiency. It is implemented using the IEEE 802.1BR standard protocol. Its core idea is: add port extension (PEX: Bridge PortExtender) equipment to the control bridge The (CB: Controlling Bridge) device serves as the remote service board of the CB device and is managed by the CB device in a unified manner. [0003] If the PEX device is a physical device, the user-side port on the PEX device has been fixed. After the PEX device is added to the CB, the CB can configure the user-side port on the PEX device in the same way as a common switch port. After the host accesses the PEX device through the user-side port on the PEX device, it forwards and process...
