|+------------------+ Memory high end When a function call occurs in a program, the computer does the following: First, the parameters are pressed into the stack;The contents of the Save instruction Register (IP) are returned address (RET); The third is the base address that is sent to the stack(FP), then copy the current stack pointer (SP) to the FP as the new base address, and finally the localAmount of space, the SP minus the appropriate value. Take the following procedure as an example:

Active Queue Management(AQM) scheme is employed. Given an ambiguity in the choice of the AQM parametersAQM is rarely used in practice. On the other hand, in the basic Drop Tail routers, the buffer sizeIs the only one parameter to tune apart of the router capacity.The first proposed rule of thumb for the choice of the router buffer size is to choose the bufferSize equal to the Bandwidth-delay Product (BDP) of the outgoing link.It is observed that the utilization of a link improves very fast with

IEEE and 10GEA (Gigabit Ethernet Alliance) are the two most important organizations in Gigabit Ethernet standardization.Gigabit Ethernet standards and specifications are many, in the standard, the first 2002 years of IEEE 802.3ae, and then continue to have a new Gigabit Ethernet specification, such as the 2006 IEEE 802.3an Standard (10GBASE-T) on the introduction of twisted-pair copper wire-based Gigabit Ethernet specification , the same IEEE 802.3aq standard introduced the 10gbase-lrm;2007-base

Some knowledge about storageAccording to the different transmission protocols, the network card can be divided into three kinds, one is the Ethernet card, the second is the FC network card, the third is the iSCSI network card. Ethernet Card: The Scientific name Ethernet Adapter, the transmission protocol for the IP protocol, generally via fiber optic cable or twisted pair with Ethernet switch connection. The interface types are divided into optical and electrical ports. Optical ports ar

, thus forming a network of hardware devices. So, the fiber-optic network card is the name in the end is the fiber port HBA card? In fact, the fiber-optic network card that you often refer to is the HBA card in the Fibre Channel networks. Because of the different transmission protocol, the network card can be divided into three kinds, one is Ethernet cards, the other is FC network card, the third is iSCSI network card. • Ethernet Card: Scientific name Ethernet Adapter, transport protocol fo

The maximum rate of Ethernet switch stack is faster, Which is multiple times faster than the port rate of the switch. Not all switches support Ethernet switch stack, 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 and cascade.

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

! But that's not the case. This is true for type-c that meet the USB 3.1 standard. USB 3.1 supports USB-PD (powerdelivery) power supply standard, the maximum power supply can reach 100 watts, charging speed will indeed be greatly improved. USB 3.1 differs from type-c USB 3.1 is the latest transmission specification based on USB, the new USB 3.1 interface will double the bandwidth to 10Gbps, and it is worth noting that the coding rate has been upgrad

transmission can result in more expensive and complex end-to-end optical networking. These traditional schemes force service providers to support a wide range of products that are not flexible, while also wasting valuable network bandwidth by using outdated equipment. Cisco's new multi-service delivery platform ONS15454 effectively solves this problem. It integrates data, voice and video services, and can be efficiently assembled on a transmission network for easy transmission. Services, inclu
