will continue to emerge, and the result will be a significant increase in the volume of business. It can be expected that in the next few years, the operator's network will be at least in the following directions. (1) The growth rate of data traffic will not be stopped. In order to adapt to this kind of demand, in the network structure, the IP/DWDM still is the mainstream. Due to the construction of the main cable in the previous few years, there i

From the data, we can see that the bandwidth of the Ethernet switch stack is dozens of times the speed of the switch port, which can effectively improve the network performance, when the number of ports that a single switch can provide is insufficient to meet the requirements of the network computer, more than two switches must provide the corresponding number of ports, which also involves the connection between switches. Basically, there are two ways to connect a vswitch: Ethernet switch stack

There is a binary file of about MB, which stores multiple JPG images. The file format is as follows: Unrelated data ZoneJpg image data ZoneUnrelated data ZoneJpg image data ZoneUnrelated data ZoneJpg image data Zone...... The starting mark of the jpg image is "FF D8 FF E0 00 10 4A", and the ending mark is "FF D9 ". What should I do if I want to read the jpg image data from this file and generate separate image files? I helped you write a program and tested a file containing only one picture.Int

The Fiber jumper (also known as the optical fiber connector), which is the optical connector to access the optical module, also has many kinds, and can not be mutually used. The SFP module is connected to the LC fibre optic connector, while the GBIC is connected to the SC fiber optic connector. The following is a detailed description of several commonly used optical fiber connectors in Network engineering: ①FC Type fiber jumper: The external streng

This has contributed to the dramatic growth of Internet users and the explosion of Internet traffic, and Figure 1 shows how the number of Internet-connected hosts changed in 1995-2000 [1], and the growth trend is more rapid than ever.

With the improvement of social informatization, information demand has been developed from simple data information to interactive multimedia information, from special service to digital, voice, image Unified service and integrated network. The traditional IP network has been unable to meet the needs of new business, the development of new business has created a "bottleneck." In this case, the broadband IP network will emerge. The so-called broadband IP is a real-time operation to ensure the qual

The most basic switching unit in optical burst switching technology is burst data. Meanwhile, BCP and burst data in OBS are separated on the physical channel, and each control group corresponds to a burst data. With the rapid growth of IP services around the world, the demand for transmission network bandwidth and switch system capacity is increasing at an unprecedented rate. Currently, DWDM technology is used in the optical layer. The available bandw

Because Fiber Ethernet has the WAN function, it is bound to promote the sale of LAN Fiber Ethernet devices to operators. Here we analyze how Fiber Ethernet breaks through its Development limitations. The Optical Fiber Ethernet product can use Ethernet devices to implement WAN communication services in the format of Ethernet data packets. This technology can be applied to any optical transmission network-optical fiber direct transmission, SDH and DWDM

connected to the optical network cannot change significantly. Even by 2017, services with 10 Gbit/s or lower end-to-end management will still occupy over 95% of the access ports in the optical transmission network [IV]. The transition to 100 Gbit/s DWDM wavelength causes a large number of rate mismatch/discontinuous problems between Client Services and WDM uplink ports, resulting in a large amount of inefficient use of optical bandwidth.

the cost of Route Search. Therefore, placing some frequently accessed destination ports in the cache can improve the routing search efficiency. Whether it is an input buffer or an output buffer router, there is a bottleneck in route search. In addition to performance bottlenecks, the stability of routers is also a common concern. 4.
