Description
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to a method and a device for acquiring NFV network signaling.
Background
The traditional network equipment is generally directly connected with CE of an IP bearing network, signaling transmission among the equipment is forwarded by the bearing network, and signaling of different protocols is generally accessed to different CEs (such as VOLTE network Session Initiation Protocol (SIP signaling for short) to be accessed to IMS CE and diameter signaling to be accessed to signaling CE), and when the signaling is collected, the signaling interaction among network elements can be converged by splitting and collecting the connection line of the network elements and each CE; because the SIP signaling and the diameter signaling are naturally separated, the shunt is relatively convenient for shunting the converged signaling flow, and the acquisition association of the network signaling can be realized through the processing of the probe.
With the advance of Information Communication Technology (ICT) convergence, many operators have started to try and virtualize Network Functions (NFV) in order to realize more agile networks and create more business opportunities and values. In the NFV network, although the signaling protocol and the interface networking adopted by each virtualized network element (VNF) are not changed, the hardware architecture is changed greatly, and the signaling traffic of the NFV network cannot be converged directly in the acquisition mode of the conventional network.
NFV networks replace those dedicated network element devices of communication networks by x86 server, storage and switching devices based on industry standards. The logic architecture of the NFV network is consistent with that of the traditional physical network, a signaling protocol and an interface networking are not changed, but the hardware architecture is changed greatly. Fig. 1 is a schematic diagram of physical networking of an NFV network provided in the prior art, as shown in fig. 1, a VNF is deployed on a host 101, and virtual machines 102 (VMs) running on one host 101 may belong to different logical network elements, so that there are the following possibilities for signaling flow between network elements:
1. the VMs 102 of different logic network elements are deployed on the same host 101, and signaling is communicated through an OVS (virtual switch);
2. the VMs 102 of different logic network elements are deployed on different blade servers under the same machine frame, or deployed on different frame servers under the same pair of access switches (TOR)103, and are communicated with each other through a machine frame backboard switch or the access switches;
3. the VMs 102 of different logical network elements are deployed in the same pair of core switches (EOR)104, different service access switches, or servers of different subracks, and communicate with each other through the core switches.
When the traditional network collects the signaling, the traffic of each interface of the network element is respectively collected to the probe for collection and association by a mode of splitting the traffic between each network element and the CE. In the above signaling flow direction, each network element is not directly connected to the CE, so that all signaling traffic in the NFV network cannot be acquired by using the signaling acquisition method of the conventional network.

Fig. 2 is a schematic flow chart of a method for acquiring NFV network signaling according to an embodiment of the present invention, where as shown in fig. 2, the method includes:
step 201: acquiring virtual network element information corresponding to all virtual network elements contained in an NFV network, wherein the virtual network element information comprises virtual network element names and virtual private network names corresponding to the virtual network elements;
specifically, the NFV network is composed of a plurality of virtual network elements VNF, each VNF may have signaling interaction, and therefore, it is first required to obtain virtual network element information corresponding to all VNFs included in the NFV network, where the virtual network element information includes a virtual network element name and a Virtual Private Network (VPN) name corresponding to the virtual network element, it should be noted that the virtual private network name corresponding to the virtual network element is related to signaling information transmitted by the virtual network element, for example: the SIP signaling IP transmitted between the two virtual network elements CSCF and ATS belongs to the IMS signaling VPN, and the diameter signaling IP belongs to the signaling VPN. In addition, the virtual network element information may also include other information, which is not specifically limited in this embodiment of the present invention.
Step 202: dividing the corresponding virtual local area networks according to the virtual network element names and the virtual private network names to obtain virtual local area network addresses corresponding to the virtual network elements, and configuring all gateways of the virtual local area networks to a switch;
specifically, signaling monitoring needs to collect signaling traffic (such as traffic from SCSF to ATS) between all virtual network elements, and generally, signaling IPs belonging to the same type of VPN are all divided into the same Virtual Local Area Network (VLAN), and when Virtualization Deployment Units (VDUs) of different network elements are on the same host and chassis, the signaling traffic can be switched in the chassis, and at this time, this part of signaling cannot be collected on the switch (EOR/TOR). Therefore, it is necessary to allocate corresponding virtual local area networks to all service IPs of each virtual network element, obtain a virtual local area network address, and configure a gateway of the virtual local area network to a switch, so that signaling traffic between different virtual network elements needs to pass through the switch.
Step 203: and acquiring the corresponding signaling information between the virtual network elements from the switch.
Specifically, since the gateways of all the virtual local area networks are configured to the switch, signaling information between all the virtual network elements passes through the switch, and therefore, the signaling information corresponding to all the virtual network elements can be acquired from the switch.
The embodiment of the invention divides the virtual local area network according to the virtual network element name and the virtual private network name, and configures the gateway of the virtual local area network to the switch, so that the signaling information of all the virtual network elements passes through the switch, and therefore, the signaling information of all the virtual network elements can be obtained by carrying out mirror image acquisition on the switch.
On the basis of the above embodiment, the method further includes:
and carrying out plane division on the NFV network to obtain a storage data plane, a hardware management control plane, an application plane and an I-layer management plane, and respectively accessing the plane data obtained after division to different switches.
Specifically, signaling in the NFV network can be divided into 4 planes, that is, a storage data plane, a hardware management control plane, an application plane, and an I-layer management plane, according to signaling attributes transmitted between virtual network elements, fig. 3 is a schematic plane diagram of the NFV network division provided in the embodiment of the present invention, as shown in fig. 3, the NFV network includes a plurality of hosts 301, each host 301 may deploy a plurality of virtual network elements, and the virtual network elements deployed on the same host 301 may belong to different logical network elements. In fig. 3, different line types are used to represent different plane configurations, and plane data corresponding to each plane is respectively connected to different switches, virtual network elements forming a storage data plane in all hosts 301 are connected to an optical fiber switch 302, virtual network elements of a hardware management control plane formed in all hosts 301 are connected to a first TOR 303, virtual network elements of an application plane formed in all hosts 301 are connected to a second TOR 304, virtual network elements of an I-layer management plane formed in all hosts 301 are connected to a third TOR 305, the first TOR 303 and the third TOR 305 are both connected to a first EOR 306, the second TOR 304 is connected to a second EOR 307, the first EOR 306 is respectively connected to a DCN CE 308 and a CMNET CE 309, and the second EOR 307 is connected to a bearer network CE 310.
The embodiment of the invention is beneficial to the isolation of various flows in the NFV network by performing plane division on the NFV network and accessing each plane data to different switches, avoids the influence of signaling information of avalanche growth on management data under extreme conditions such as signaling storm and the like, and is also convenient to collect pure service signaling information on a port of a bearing application plane of the switch.

(1) virtual Private Networks (VPN) with the same name can be planned in the same VLAN, and one VLAN ID represents one VLAN;
(2) for VPNs with different virtual network element names and the same VPN, it has to be planned into different VLANs.
For example, IMS is taken as an example, the IP used by the virtual network element may be divided into DCN IP (for operation and maintenance), IMS signaling IP (for communication of SIP signaling), IMS media IP (for MRFP media playback, etc.), charging IP (for communication with the BOSS), and signaling IP (for communication of diameter signaling), and these IP addresses belong to OM VPN, IMS signaling VPN, IMS media VPN, Bill _ Pro VPN, and signaling VPN, respectively.
The following table is an example of dividing a virtual local area network into virtual network elements, and it can be known from the table that, for a virtual network element with a virtual network element name of the CSC3300, when all VPNs to which the virtual network element belongs are IMS signaling, corresponding VLAN IDs thereof are the same, that is, the virtual network element is divided into the same VLAN. In addition, for two different virtual network elements CSC3300 and ATS9900, the VLANs to which they belong are different, even though there is IMS signalling.
