Problems solved by technology

[0006] Although the existing processing method has the advantage of being simple and easy to implement, it has the following disadvantages: it cannot distinguish messages, and all broadcast messages will be discarded, which affects some protocol messages and service messages, such as two More important broadcast messages, one is the ARP (Address Resolution Protocol, Address Resolution Protocol) request message in which the DMAC (destination medium access control address) is the broadcast MAC (Medium / Media Access Control, medium access control), which affects the ARP protocol , the second is the broadcast message that needs to be forwarded through the PTN network, which affects some services on the PTN network

Embodiment Construction

[0042]The main idea of ​​the solution in the embodiment of the present invention is: in the chips of most processors in the PTN network, there are access control lists, and the biggest advantage of the access control list is that it can distinguish messages for processing. The advantage of the list is that by setting the three access control list entries to work together, it is possible to discard broadcast packets, layer 2 unknown multicast packets, and layer 2 unknown unicast packets while maintaining ARP request packets and passing through the PTN network The normal forwarding of forwarded broadcast messages effectively suppresses PTN network storms without affecting PTN network services.

[0043] Such as figure 2 As shown, an embodiment of the present invention proposes a method for suppressing a network storm, including:

[0044] Step S101, the processor obtains the message to be forwarded by the PTN network;

[0045] During the process of MPLS forwarding of packets be...

Abstract

The invention relates to a method and a processor for restraining Internet storm. The method comprises that the processor acquires massages to be forwarded by PTN (packet transport network); the massages are resolved, and the massage characteristics of the massages are acquired; and according to the massage characteristics, the massages are forwarded or dropped based on an access control list comprising the preset match forwarding policy. According to the invention, through setting the match forwarding policy of the corresponding massage characteristics in the access control list, ARP (address resolution protocol) request massages, MPLS (multi-protocol label switching) forwarding massages, non MPLS forwarding broadcast massages, two-layer unknown multi-cast massages and two-layer unknown unicast massages in broadcast massages to be forwarded of the PTN network are separated, and the corresponding forwarding or dropping treatment is carried out. Not only is the PTN network storm restricted, but also the drop of the broadcast massages supported by the PTN is avoided, and the service performances of the PTN network are improved.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and processor for suppressing network storms applied to network devices such as switches. Background technique [0002] At present, with the rapid development of communication technology, how to ensure that data services are not impacted by network storms has become an important problem to be solved in the communication field. Among them, the development of the bearer network is advancing by leaps and bounds, and the PTN (Packet Transport Network, Packet Transport Network) network is one of the most important network forms. PTN is an optical transport network. Its specific architecture includes: a layer is set between IP (Internet Protocol, a protocol for interconnection between networks) services and the underlying optical transmission medium. Designed for the requirements of multiplexing transmission, with packet services as the core and supporting multi-servic...
