data link layer. As an ISO standard, HDLC is based on the ibm sdlc protocol, and SDLC is widely used in IBM mainframe environments. In HDLC, SDLC is called the call response mode (NRM ). In normal response mode, the base station (usually the mainframe) sends data to a local or remote second-level Station. Different types of HDLC are used for networks using the X

bytes, used to indicate the upper layer protocol contained within the Ethernet frame. The protocol identifier for the frame format. For IP messages, the field value is 0x0800. For ARP information, the value of the Ether Type field is 0x0806.Payload: A protocol Data unit PDU consisting of an upper layer protocol. The maximum payload that can be sent is 1500 bytes. The payload is at least 46 bytes due to the collision detection feature of Ethernet. If the upper-layer protocol data unit is less th

CIP technology: CIP is the Channel Interface Processor ). It is a plug-in card device that can be conveniently installed in

completed as early as possible in the Software development Lifecycle (SDLC), a good simulator based development strategy can achieve significant optimization in the development process. This is especially important for deploying new applications and systems to an existing environment, such as in the telecommunications sector, where a large number of independent Software vendor (ISVs) are mixed, and non-functional requirements are important, especial

As a former programmer, Chris said: "I feel like I can't do anything in non-programming software ." This is not true for operators with limited programming skills, but Chris thinks this will limit their ability to work in the future. Looking at automated IT operations from a more developmental perspective is Chris's central idea of the "
