Benefits of technology

The technical effect that this new technology solves by allowing for better control over how data flows across different networks during communication sessions without interrupting any other connections or disrupts their normal functioning.

Problems solved by technology

This patented describes two technical flipups - Load Balance Protocol Switching (LSP)-based Network Interior Gateway Passage Group (NARG). These techniques involve managing multiple spare paths within a specific area where devices connect directly without being overloaded. However, these methods require complex configurations and may cause delays during packet delivery due to reconfiguration processes.

Embodiment Construction

[0049] In order to make the public understand the present invention better, the following knowledge is firstly introduced.

[0050] (1) VRRP packet format, VRRP packets are encapsulated in IP packets, and the protocol number is 112; the Master router regularly sends VRRP packets in multicast mode to announce its own existence, and VRRP packets can be used to detect the virtual routers. This parameter can also be used for the election of the Master router.

[0051] The current VRRP standard protocol includes VRRPv2 and VRRPv3 versions. VRRPv2 specifies the packet format of IPv4VRRP, and VRRPv3 specifies that IPv4VRRP and IPv6VRRP adopt the same packet format. For example, image 3 The VRRPv2 message format diagram of the VRRP standard protocol and Figure 4 The VRRPv3 packet format diagram of the VRRP standard protocol is shown.

[0052] exist image 3 In , each field is interpreted as: Version, the protocol version number, the version number corresponding to VRRPv2 is 2; Ty...

Abstract

The invention discloses a method and equipment for switching between a standard VRRP (Virtual Router Redundancy Protocol) and a load balancing VRRP. The method comprises the following steps of: when member equipment acquires information for switching from the standard VRRP to the load balancing VRRP, performing the processing flow of the load balancing VRRP under a Master state if the member equipment is Master equipment, and informing a terminal of the corresponding relationship between a virtual IP (Internet Protocol) address and a plurality of virtual MAC (Multi-Access Computer) addresses; and performing the processing flow of the load balancing VRRP under a Backup state if the member equipment is Backup equipment. In the invention, the flow passing through a virtual router cannot be interrupted in the switching process between the standard VRRP and the load balancing VRRP.
