Problems solved by technology

[0005] 3. After the original dedicated hardware-supported business nodes are virtualized, their individual high performance is replaced by virtual machines. The relative performance decline will lead to a decrease in the efficiency of the business nodes, and the burden will also increase with the increase of tenants, which is prone to failure or overload
[0006] To sum up, after network function virtualization, a large number of service nodes need to be managed, and it becomes more complicated to support its reliability, high availability, and scalability. Traditional manual configuration obviously cannot meet the requirements.

Embodiment 1

[0101] Combine below figure 2 Illustrating the preferred embodiment 1 of the present invention, the processing flow of service node registration is as follows:

[0102] The service nodes in this embodiment of the present invention are all service nodes (such as vFW, vLB) that have been successfully created, and their relevant function templates are delivered by the management and configuration device. The next hop of Service Node1 is Service Node2, 1b distributes the LB service template to Tenant A, and 1c delivers the WoC service template without specifying the tenant;

[0103] The service node configures corresponding functions, as shown in step 2a, the service node configures the firewall service, 2b service node configures the LB service, and 2c service node configures the WoC service;

[0104] After the business node is successfully created, it is registered with the business node pool registrar to become a part of the available business node database, as shown in step ...

Embodiment 2

[0105] Combine below image 3 Describe the preferred embodiment 2 of the present invention. After the firewall service node executes the first packet and passes, the logout process is as follows:

[0106] The first packet passing function supported by the firewall mainly refers to: after the first packet is passed, it is confirmed that the packets of this type of forwarding information meet the requirements, so that the forwarding entry is directly issued to the forwarding device, so that the subsequent packets with the same forwarding attribute can pass directly without It needs to be processed by the firewall again, so as to improve the processing efficiency;

[0107] To cancel the business node, it needs to send a cancel message to the business node pool registrar, and at the same time, it needs to attach the identification information of the business node that jumps up and down, so as to update the relevant content in the business node database;

[0108] Finally, the mana...

Embodiment 3

[0119] Combine below Figure 4 Describe the preferred embodiment 3 of the present invention, the processing flow of the replay of the service node is as follows:

[0120] For the replay of service nodes, the most important thing is to query the eligible source service nodes and destination service nodes in the service node database of the service node pool registrar according to the restrictions of replay;

[0121] If two corresponding service nodes can be found, the subsequent operations are the deregistration and release of the source service node, the creation and update of the destination service node, and the update of the service node chain.

[0122] The specific steps are:

[0123] 1. The management and configuration equipment submits the restriction conditions for the relocation of the service node replay (the location of the source node and the destination node of the service relocation, functional specifications, Relocation strategy, etc.);

[0124] 2. The busine...

Abstract

The invention discloses a service node configuration method: receiving a service node query request sent by a management configuration device, the service node query request including service requirements from users or caused by network changes; Node query requests matching service node information, the matching service node information includes matching service node identification, location information, status information, selection strategy for the status information, tenant ID and service chain that meets the business requirements One or several paths; sending the matching service node information to the management configuration device, so that the management configuration device can match the matching service node information according to the obtained network topology information and the matching service node information Nodes perform network and service configuration.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a service node configuration method, a service node pool registrar and a system. Background technique [0002] In traditional data centers, service nodes usually exist in physical form, with a limited number and fixed locations, and can be configured manually. However, network virtualization brings new requirements: [0003] 1. Multi-tenant requirements for virtualization: The business isolation of tenants requires that each tenant network has different types and numbers of business nodes; [0004] 2. Cloud-based interconnection of data centers: The interconnection of multiple data centers into a virtual, cloud-based data center will greatly increase the number of service nodes, and virtual service nodes can be deployed in any location; [0005] 3. After the original service nodes supported by dedicated hardware are virtualized, their independent high performanc...
