We all know that PPPoE is a point-to-point transmission protocol in Ethernet. In this article, we will carefully summarize some of the working principles, characteristics, and application content of this protocol, hoping to help you learn it. I. PPPOE Protocol Introduction PPPOE, short for Point-to-Point Protocol Over Ethernet, works at the OSI data link layer. PPPOE Provides broadcast-type networks such as Ethernet) multiple hosts are connected to the Remote Access

,num_initagents,max_coordagents,max_connections, Maxcagents. Here is a brief introduction to them: MAXAGENTS: This parameter is the total number of agents in the current instance, including the coordination agent, the sum of the idle agent and the sub-agent. However, this parameter is no longer used in DB2 V95. num_poolagents: This parameter is used to control the number of idle agents in the agent pool. When the active agent completes the work Return agent pool becomes an idle agen

Working principle of PPPOE ProtocolThe PPPoE protocol workflow consists of two phases: discovery and session. The discovery phase is stateless to obtain the Ethernet MAC address of the PPPoE end (on the local ADSL device, create a unique PPPoESESSION-ID. After the discovery stage ends, it enters the standard PPP session stage. When a host wants to start a PPPoE session, it must first perform the discovery phase to identify the local Ethernet MAC address and create a PPPoESESSION-ID. In the disco

I have the opportunity to transfer the development of the IOT Group to this master for the first time. The first project gave me access to smart electric meters. I just got in touch with this stuff and it was confused. Writing this article does not provide technical learning, but I think it is fresh to write some processes, because it was previously B/S.The main devices for this project are: one single table, one three tables, one concentrator, two el
