Problems solved by technology

Therefore, the length of the search key of the binary tree supported by this type of network processor is limited;
[0030] 3. Use software to construct a binary tree in memory, and the length of the search key of the tree is not limited by the hardware; however, there is also the problem that the longer the search key, the longer the search time, and the greater memory consumption
[0035] It is not difficult to see that the above implementation method only avoids the existing problems, adopts the second best implementation method, and does not fundamentally solve the existing problem of too long search keywords
[0036] In addition, because the above implementation method cuts down the keywords of flow statistics, the granularity of flow statistics will inevitably become coarser.
Therefore, using the above implementation method, it is impossible to achieve the same fine statistics of IPv6 service flows as for IPv4 service flows, and it is even more impossible to realize accurate statistics of various traffic between hosts

Embodiment Construction

[0068] The core of the present invention is to provide a means to effectively solve the problem that the length of the cache search keyword is not enough when IPv6 flows are counted, and can simultaneously add other attributes to the destination IPv6 address and source IPv6 address to make statistics. IPv6 flow statistics can reach the granularity of IPv4 flow statistics, that is, fine flow statistics for IPv6 service flows can be realized.

[0069] In order to have a further understanding of the present invention, the flow statistics processing process in the prior art will be described below first.

[0070] In the flow statistics process, it is usually implemented by dynamically creating a cache. First, a part of the cache is allocated for flow statistics in the system to store flow information. When a message needs to be counted, use the seven-tuple (or other information) of the message to search the cache of flow statistics, if the search hits, count the length and number...

Abstract

The invention relates to a method for taking statistics for operation flow based on IPv6 that includes the following steps: building up the corresponding relationship of IPv6 address and the flow statistics mark information less than the IPv6 address length; using the flow statistics mark information taking place of IPv6 address to constructing searching keywords that would be used as the index of flow statistics information to take statistics for the receiving operation flow. The invention could realize statistics for kinds of flow between IPv6 hosts.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for counting IPv6-based service flows. Background technique [0002] At present, most of the networks used on the Internet are IPV4 networks, and data packets are transmitted in the format of IPV4. [0003] The packet format of IPv4 is as follows: [0004] IP header Payload [0005] Wherein, the format of the IP packet header is as follows: [0006] 0 1 2 3 4 5 6 7 0 1 2 3 4 5 6 7 0 1 2 3 4 5 6 7 0 1 2 3 4 5 6 7 Version IHL Type of Service Total Length Identification Flags Fragment Offset Time to Live Protocol Header Checksum Source Address Destination Address Options ...
