Description

EVPN Overlay topology and real-time alarm display method and device

Technical Field

The invention relates to the field of communication, in particular to an EVPN Overlay topology and real-time alarm display method and device.

Background

The network cloud resources of operators currently lack an EVPN Overlay network fault location tool, which results in a failure that cannot be perceived in time when the network fails.

In the EVPN (Ethernet VPN) Overlay network, the reasons why the fault localization becomes complicated are mainly the following:

complexity of overlay network: an EVPN Overlay network is a virtualized network architecture that creates a logical Overlay network over the underlying physical network. This virtualized network architecture increases the complexity of the network, making fault localization more difficult. Faults may occur at multiple levels of the underlying physical network, the control plane, the data plane, etc. of the Overlay network, and multiple factors need to be comprehensively considered to perform fault location.

2. Multilayer network tunnel: EVPN Overlay networks typically use tunneling (e.g., VXLAN, GRE, etc.) to enable the expansion and isolation of virtual networks. These tunnels create multiple levels of encapsulation in the network, allowing the data flow to traverse multiple network levels, thereby increasing the complexity of fault localization. When a failure occurs, it is necessary to determine whether a problem has occurred with the underlying physical network or a problem has occurred with a tunnel in the Overlay network.

3. Distributed control plane: EVPN Overlay networks typically employ a distributed control plane architecture in which network devices interact and exchange information via control plane protocols (e.g., BGP, MP-BGP, etc.). Such a distributed control plane complicates fault localization because faults may occur at a certain node in the control plane or communication between the control planes is problematic.

4. Multi-vendor environment: in a practical network, there are often cases where equipment and technologies of multiple suppliers are deployed in a mixed manner. Different vendor devices may have different implementations and features, which add to the complexity of fault localization. Compatibility and interoperability of different vendor devices need to be considered when a fault occurs, coordination and troubleshooting with multiple vendors may be required.

In summary, the complexity of the EVPN Overlay network, the multi-layered network tunnel, the distributed control plane, and the multi-provider environment all cause the fault location to become very complex. To effectively solve the failure, the network architecture and technology need to be fully known, comprehensive analysis and troubleshooting are performed, and professional network failure positioning tools and technical support may be needed.

For a clearer explanation of the EVPN Overlay topology and the real-time alert presentation method described above, a specific embodiment will be described below, however, it should be noted that this embodiment is only for better explaining the present invention, and does not constitute an undue limitation of the present invention.

Operator network model simplification as shown in fig. 1, a Spine-Leaf network topology architecture, in which propagation and collection of EVPN Type2 routes is implemented through BGP (Border Gateway Protocol).

Fig. 2 is a flow chart of the EVPN Overlay topology and real-time alert display method of the present invention, as shown in fig. 2:

Type2 routing format, take as an example the Type2 routing sent by Leaf1 to Leaf2, the format is as follows table 1:

wherein

TABLE 1

And analyzing and storing the Type2 routing information, wherein the stored data comprises two parts, one part is real-time latest routing information and the other part is routing change information.

The real-time routing information mainly includes the following content, which can be obtained by analyzing the EVPN Type2 route, as shown in the following table 2:

TABLE 2

The change message for the EVPN Type2 route is typically propagated through BGP UPDATE messages.

When a new MAC address needs to be announced or an existing MAC address needs to be updated or deleted, the Spine switch generates a corresponding EVPN Type2 route change message and sends the message to other devices through a BGP UPDATE message.

And judging the type of the change message by analyzing the value of the BGP general attribute object bgp_attr_type.

If the value is 14, the route is reachable as a new route or an updated route, and whether a corresponding route exists in the real-time route message needs to be judged at the moment;

if the corresponding route exists, updating the existing data, adding a change message in a route change information table, and recording information before and after the change;

if the corresponding route does not exist, a route record is newly added, and a record of the newly added route is added in the route change information table.

If the value is 15, the route is not reachable, and the corresponding route information in the real-time table needs to be deleted, and a deleted route record is added in the route change message table.

The route change information mainly contains the following, table 3 below:

TABLE 3 Table 3

The VTEP device (Leaf device) is denoted as a point and the virtual device (identified by a MAC address, such as the MAC address of Host 1) is also denoted as a point.

By querying the real-time routing information table, the link relationship between the VTEP device and the virtual device can be obtained.

Specifically, the next hop address may be acquired by referring to the real-time routing information table, which is denoted as a VTEP device, such as OVS1, OVS2, or the like; simultaneously acquiring the MAC address of the host, and representing the MAC address as a virtual device, such as VM1, VM2 and the like; in this way, a link relationship between the VTEP device and the virtual device can be obtained.

The following topology data is generated from the device and link information, points are used to identify individual devices, and lines are used to identify links between devices:

s03, refreshing topology in real time;

As shown in fig. 4, the process flow of deleting the route change message includes:

As shown in fig. 5, the visualization interface represents the EVPN Overlay topology by using points and lines, while using different legends to represent different alarm types to help administrators better understand and manage the network.

In the topology, each device is represented in the form of a dot, and the connection relationship between the devices is shown in the form of a line. The device can use different colors and lines to represent different alarm types:

for example, the virtual machine offline alert may be represented using dotted points and lines, such as VM1 in FIG. 5;

Virtual machine on-line may be represented using a line and a + sign, such as VMm in fig. 5;

virtual machine migration may be represented using two lines, such as VMn in fig. 5.

Meanwhile, the interface supports a real-time refreshing function, and when a refreshing message is received, the interface can update the topological graph and the alarm information in time, so that the real-time performance of display is ensured. The administrator can know the topology change and the alarm occurrence at any time through the interface, and timely take measures to process.
