Three, 100G type of Ethernet
In 802.3ba, the following types are defined for 100GE:
100gbase-cr10
100gbase-cr10 is the 100gb/s signal in the copper cable application of the specification, the 10x10g (based on 10GBASE-KR) of the parallel mode, transmission distance of 7m. It is mainly used in the interconnection between rack/cabinet or rack/cabinet.
100gbase-sr10
100GBASE-SR10 is a specification for 100GB/S signals to be applied on multimode fibers, and
. The DMD mode of the optical fiber must meet one of the six templates listed in the following table.

Cascade GBIC Module
The GBIC modules used for Cascade are divided into four types, one is 1000Base-TGBIC module (1), which is applicable to cat5e or cat6 twisted pair wires and the maximum transmission distance is 100 meters; the second is the 1000Base-SXGBIC module (as shown in figure 2). It is applicable to multimode multi-fiber (MMF) and has a maximum transmission distance of 500 meters.

transmission rate, including 8 gbabit Fiber Channel and 10GbE. Introduced the SFP + module version of optical fiber and copper core,
Compared with the Xenpak, X2, or XFP version of the module, the SFP + module retains some circuits on the main board, rather than in the module.
SFP type
SFP transceiver has a variety of different sending and receiving types. You can select an appropriate transceiver for each link to provide available optical fiber types (such as multimode or single-mode

It calls the kernel layer directly.For malloc and new, these 2 are not operating system APIs, they are language-provided functions. There are different implementations on different systems, on Windows, new calls the Malloc,malloc call heap function (HEAPXXX), and the heap function calls the virtual series function. On Linux,
