Problems solved by technology

[0003] When the sum of the link bandwidth of L1 and the link bandwidth of L2 is greater than the link bandwidth of L3, link congestion may occur on the E1 / 3 port of the network device
When the link congestion occurs on the E1 / 3 port of the network device, because the network device does not support the TRILL protocol, when the network device transparently transmits the TRILL protocol packet, it will transparently transmit the TRILL protocol packet together with the data packet. TRILL protocol packets may be discarded due to port congestion, resulting in interruption of TRILL data traffic, failure to establish TRILL neighbors, and confusion of unicast routing entries.
For example, when the TRILLhello packets used to maintain TRILL neighbor information cannot be preferentially scheduled on the E1 / 3 port of the network device, the TRILLhello packets are lost, and the establishment of TRILL neighbors fails.

Embodiment Construction

[0038] Aiming at the problems existing in the prior art, the embodiment of the present invention provides a protocol packet processing method, the application scenarios of the method include but not limited to figure 1As shown in the TRILL network, as long as there is link congestion on the network equipment, the technical solution provided by the embodiment of the present invention can be used; for example, under the Internet packet switching network, since the current available link resources are less than the normal forwarding required link Link congestion scenarios caused by resources; link congestion scenarios caused by abnormal packets exhausting a large amount of link resources when the current network is attacked by a large number of abnormal packets. like figure 2 As shown, the method includes the following steps:

[0039] In step 201, the network device detects that the outbound port of the network device is congested.

[0040] When a network device receives a pro...

Abstract

The invention discloses a method and equipment for processing protocol messages. The method comprises: when a network device detects link congestion at an outgoing port of the network device, extracts the protocol message from the data buffer by using the protocol type feature, and converts the The extracted protocol message is sent to the CPU for processing, and the feature of the extracted protocol message is recorded in the feature library; after the network device receives the protocol message, it uses the feature information in the protocol message to query the feature library; if there is a record corresponding to the feature information in the feature library, the protocol message is sent to the CPU for processing; if there is no record corresponding to the feature information in the feature library, the protocol message is sent to the The message is stored in the data buffer. In the embodiment of the present invention, can TRILL be avoided? Packet loss occurs in hello packets.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a protocol message processing method and equipment. Background technique [0002] In a TRILL (TRansparentInterconnectionofLotsofLinks, transparent interconnection of multiple links) network, a network topology such as figure 1 As shown, it includes RB (RoutingBridge, routing bridge) ingress (entrance) 1, RBingress2, RBegress (exit) and network devices that do not support the TRILL protocol; among them, RBingress1 is RB2 in the figure, RBingress2 is RB1 in the figure, and RBegress In the figure, it is RB3, and the network device is DUT1 in the figure; in addition, the E1 / 1 ports of RB1, RB2, and RB3 are all enabled with TRILL protocol, and the network device needs to transparently transmit TRILL protocol packets. [0003] When the sum of the link bandwidth of L1 and the link bandwidth of L2 is greater than the link bandwidth of L3, link congestion may occur on the E...
