Embodiment Construction
[0034] In order to better understand the present invention, the content of the present invention will be further described below in conjunction with the accompanying drawings and examples.
[0035] The present invention provides an OpenFlow protocol asynchronous message mapping method, the method comprising:
[0036] Step 1. Select dc.title as the key retrieval point, dc.identifier as the auxiliary retrieval point, and dc.description as the explanatory information in the Dublin core metadata of the RFC2413 standard. Such as figure 1 shown.
[0037] Among them, it can be seen from the 15 items in Table 1 that the Dublin Core metadata solution defined by RFC2413 comprehensively summarizes the main characteristics of electronic resources, covering important retrieval points (items 1, 2, 3), auxiliary Access points or associated access points (items 5, 6, 10, 11, 13), and valuable descriptive information (items 4, 7, 8, 9, 12, 14, 15); secondly, it is concise and prescriptive. ...

The present invention relates to an OpenFlow protocol asynchronous message mapping method, said method comprising: selecting from RFC2413 standard Dublin core metadata: key retrieval points, auxiliary retrieval points and descriptive information; setting said key retrieval points, auxiliary retrieval points and the character length of the descriptive information; the key retrieval point and the auxiliary retrieval point are respectively mapped with the OpenFlow protocol general message header Type field and the Xid field; the descriptive information is respectively with the Packet_in message and the Flow_Removed message of the OpenFlow protocol asynchronous message , Port Status message and Error message correspondence; The present invention selects three most relevant signs with OpenFlow protocol asynchronous message in 15 Dublin core elements, and corresponds with the asynchronous message data structure, maps out the data structure model of 112bits, and this model It can summarize the main characteristics of asynchronous messages concisely and standardizedly, and is easy to find and manage standardizedly.
Description
technical field [0001] The invention relates to a method for realizing asynchronous message mapping, in particular to an OpenFlow protocol asynchronous message mapping method. Background technique [0002] The Dublin Core Elements Set based on the RFC2413 standard is an international metadata solution dedicated to standardizing the architecture of Web resources. It defines a common core standard that all Web resources should follow. Through 15 core metadata, it solves the Standard issues for electronic resources. [0003] Dublin Core Element Set (hereinafter referred to as DC) is an international metadata solution dedicated to standardizing the architecture of web resources. It defines a common core standard that all web resources should follow. Its content is more It is less common and more general, so it is widely supported by other related standards. [0004] The Dublin core element set logo includes: Title, Creator, Subject, Description, Publisher, Contributor, Date, T...
