Embodiment Construction

[0026] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0027] A flexible and scalable Ethernet message excitation generator, its detailed description is as follows:

[0028] (1) Inheritance relationship of all classes under ethpkt

[0029] ethpkt_head is basically inherited from ethpkt_head_base, of course, some classes are exceptions, such as ethpkt_head_eth_mpls, which is the base class of mpls and is extended on the basis of Ethernet.

[0030] (2) ethpkt framework and extension

[0031] Such as image 3 The ethpkt framework is shown. There are 6 classes in the root directory, 4 of which are: flag, head, payload, and fcs; these four correspond to the four parts of flag, head, payload, and fcs in the frame format.

[0032] The other two classes are: queue class and item class; the former describes the four-layer head of the L2-L5 layer, including framing and unframing of each layer; the latter is a...

Abstract

The invention discloses a flexible and extensible Ethernet message excitation generator which is an ethpkt framework, a root directory of the ethpkt framework has six classes, and four classes are flag, head, payload and fcs; the four parts respectively correspond to the flag, the head, the payload and the fcs in the frame format; the other two classes are a query class and an item class; four layers of head (L2-L5) are described by a query class, wherein the four layers comprise framing and deframing of each layer; the item class is a complete description of the whole frame structure; when ethpkt needs to be instantiated in other classes, the item is directly instantiated. According to the generator disclosed by the invention, all required messages can be constructed by one case, so that the verification efficiency and the verification completeness can be greatly improved; the invention has expandability, and a user can construct a required message format by himself / herself, even if the format does not conform to the message format specification; and various modes of the packet length of the message can be configured.

Description

technical field [0001] The invention relates to the technical field of Ethernet messages, in particular to a flexible and expandable Ethernet message excitation generator. Background technique [0002] Ethernet is a computer local area network technology. The IEEE802.3 standard of the IEEE organization has established the technical standard of Ethernet, which stipulates the content of the connection, electronic signal and medium access layer protocol including the physical layer. Ethernet is currently the most widely used LAN technology, replacing other LAN technologies such as Token Ring, FDDI, and ARCNET. There are two types of Ethernet: Classic Ethernet and Switched Ethernet. Classical Ethernet is the original form of Ethernet, and its operating speed ranges from 3 to 10 Mbps, while switched Ethernet is a widely used Ethernet, which can run at high rates of 100, 1000 and 10000 Mbps, respectively with Fast Ethernet , in the form of Gigabit Ethernet and 10 Gigabit Ethern...
