Embodiment 1

[0089] A virtual port management method, such as figure 2 As shown, can include:

[0090] Step 201, establishing a mapping from a physical port to a vPORT;

[0091] Step 202, update the virtual port state according to the state of the physical port, and the virtual port state is synthesized by port management state, operation state and protocol state.

[0092] The management method of the virtual port in this embodiment, by establishing a mapping relationship between the physical port and the virtual port and monitoring and managing the status of the virtual port, facilitates the sharing of network resources of the SDN-based OLT and the unified management of the interface. On the one hand, it can It meets the operation and maintenance management requirements of the new SDN access network in the future. On the other hand, it helps to solve practical problems such as the definition of responsibilities of basic operators and virtual operators, and network operation and maintena...

example 1

[0121] From image 3 It can be seen that the various types of access network interfaces introduced in different eras are not conducive to the sharing of network resources and unified management of interfaces in the subsequent SDN-based OLT. This is a prominent contradiction at present. In addition, SDN-oriented network management tends to adopt the new NETCONF / YANG management tool, which has a big gap with the traditional network management model. So, if image 3 As shown, it is necessary to define a resource management model in which physical ports based on different access hardware platforms are abstracted into virtual ports and service flows.

[0122] The definition of vPORT is as follows: vPORT is designed to provide a virtual interface dedicated to Ethernet services based on link resources for virtual operators. As a port for data forwarding, it represents a business unit and only focuses on the business itself. Its creation, deletion, and state modification are maintai...

example 2

[0143] The state of a virtual port can be synthesized through the following three types of states:

[0144] 1) Port management status: port enabling and closing status from the operator or manager.

[0145] 2) Operating status:

[0146] a) The state of the physical link, the state of the UNI physical port associated with the virtual port.

[0147] After the physical port is closed (DOWN), according to the OMCI definition, a LAN-LOS alarm will be sent to notify the OLT; according to the LAN-LOS signal, the operating state of the virtual interface will be changed to DOWN.

[0148] b) OAM-related status alarms of ports enabled with Ethernet OAM.

[0149] B1. The IEEE 802.3ah EFM function is enabled, and the port supports link monitoring and detection.

[0150] Support general link events: Errored Frame Event (error frame event), Errored Frame PeriodEvent (period error frame event), Errored Frame Seconds Summary Event (error frame second-level summary event), support RDI (send ...

Abstract

The invention discloses a virtual port management method and device. The method comprises the following steps: establishing a mapping between a physical port and a virtual port vPORT; and updating thestate of the virtual port according to the state of the physical port, and synthesizing the state of the virtual port through a port management state, an operation state and a protocol state. The virtual port management method provided by the invention facilitates network resource sharing and unified management of interfaces of an SDN (Software Defined Network) OLT (optical line terminal).

Description

technical field [0001] The invention relates to the communication field, in particular to a virtual port management method and device. Background technique [0002] With the maturity of the access network technology and "optical advance and copper retreat", it has become an unstoppable fact in global broadband network construction. Fiber to the home (FTTH, Fiber to the home) has gradually become the focus of network development and the ultimate goal of network construction. Various traditional digital subscriber lines (xDSL, Any Digital Subscriber Line), Ethernet Passive Optical Network (EPON, Ethernet Passive Optical Network), Gigabit Passive Optical Network (GPON, Gigabit-Capable Passive Optical Network) and future 1OG PON, The next generation of PON (NG-PON2, Next Generation PONVersion2) needs to study the management model for fiber to the home (FTTH, Fiber to the home), so as to simplify the operation and management of the traditional access network, face user services,...
