Embodiment 1
[0029] The embodiment of this application can run on figure 1 On the network architecture shown, figure 1 is a network architecture diagram of an embodiment of the present invention, such as figure 1 As shown, the network architecture includes: a first routing device 10 and a second routing device 20, wherein the first routing device and the second routing device send and receive messages.
[0030] In this embodiment, a method for determining the priority of a message running on the above-mentioned network architecture is provided, figure 2 is a flow chart of message interaction according to an embodiment of the present invention, such as figure 2 As shown, the process includes the following steps:
[0031] Step S202, receiving an Address Resolution Protocol ARP message;
[0032] Step S204, determine the white list protection entry of the ARP message according to the subscription information of the dynamic routing protocol.
[0033] Through the above steps, since the wh...
Embodiment 2
[0051] In this embodiment, a device for determining and sending message priority is also provided, and the device is used to implement the above embodiments and preferred implementation modes, and those that have been described will not be repeated. As used below, the term "module" may be a combination of software and / or hardware that realizes a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementations in hardware, or a combination of software and hardware are also possible and contemplated.
[0052] image 3 is a structural block diagram of a device for determining message priority according to an embodiment of the present invention, such as image 3 As shown, the device includes:
[0053] A receiving module 30, configured to receive an Address Resolution Protocol ARP message;
[0054] A determining module 32, configured to determine the white list protection entry of the ARP message accordin...
Embodiment 3
[0064] In this embodiment, an ARP identification and protection method and device (system) based on routing protocol subscription are provided, which are applicable in the scenario of an ARP attack. The device can effectively distinguish attack ARP messages from legal ARP messages, and ensure normal processing of legal ARP interaction messages subscribed by routing protocols, thereby ensuring normal interaction of routing protocols.
[0065] This embodiment is based on the ARP identification protection method and device (system) of routing protocol subscription, such as routing equipment, including the following components:
[0066] Component A——routing-related components: responsible for routing link building, keeping alive, and routing notification.
[0067] Component B——ARP-related components: responsible for maintaining and refreshing ARP entries, sending keep-alive packets, etc.; keep-alive packets (Keep Alive Packet) are a form of message interaction in the communication...
