Here we will analyze some specific content of the PPPoE protocol. We have also studied the PPP protocol before, so we can understand PPPoE more easily. This time we will also talk about the PPPoE discovery stage. Data packets of the PPPoE protocol are encapsulated in the data domain of the Ethernet frame. Ethernet frame headers include: 1. Target MAC address (the broadcast address in this phase is ffffffffffff) 2. source MAC address client MAC address) 3. Ethernet protocol type (this stage is 0x

the database.For private sorting, the Database Manager configuration parameter sheapthres Specifies the soft limit of the total amount of memory that a private sort can consume at any point in the instance range . If the total private sort memory consumed by an instance reaches this limit, the memory allocated for additional incoming private sort requests is greatly reduced. This will see the following message in Db2diag.log: "Not enough memory available for a (private) sort heap of size size o

Apic-em hosts a large number of embedded services, including (but not limited to) network PNP, path tracking, PKI certificate infrastructure, and network assets. You can view all of these apps from th

The process is described as follows:(1) host sends a layer-2 broadcast packet and waits for Access Concentrator to respond;(2) Access Concentrator/concentrators (one or more) After receiving the broadcast, If you can provide the services required by (offer), send an off

multiplexed channel is widened. 2, Time Division Multiplexing TDM (Time Division Multiplexing) Time division multiplexing is divided into a section of the length of the interval multiplexing frame (TDM frame), each of the users in the TDM frame in each of the fixed number of time slots. The time slots that each user occupies are periodically present (the length of the TDM frame is the period). Time-division multiplexing users occupy the same band width at different times.

Wireless local Area network (small) in the past, is used to send and receive e-mail and browsing the web, the wireless LAN is usually used by radio frequency experts manual tools to troubleshoot network failures. However, as the data flow size and diversity become more and more significant, coupled with wireless LAN has become one of the main means of network access, wireless LAN fault repair methods have been rapid growth. How WLAN management tools improve the ability of WLAN troubleshooting

Application Analysis of smart street lamp ZigBee technology In the dark night, the street lights light up the way forward for everyone. When the night comes, the street lights are lit up. As there are more pedestrians on the road, the darker the sky, the brighter the street lights. When the night begins, when there are few pedestrians on the road, the street lights become darker, saving energy for urban lighting. Figure 1: adjustable lighting So how does a street lamp control brightness coordi

technologies, their ecology, and their comparisons. LoRa: Low-Power wide-area object-linked technology for easy construction and deployment Lora was born earlier than Nb-iot, in August 2013, Semtech company released a new type of chip based on 1GHz of ultra long distance low-power data transfer technology (long Range, short Lora). Its acceptance sensitivity has reached astonishing -148dbm, and the highest reception sensitivity has improved by more than 20db compared to other advanced level Sub-

Today, most enterprise-class WLAN products and many SMB products offer built-in guest management capabilities. From simple forced network portals and firewalls to traffic shaping and unique guest logins, such products can be automatically generated without it assistance. For example, let's look at the guest management capabilities provided by the enterprise-class WLAN cloud controller in Meraki. In order to create a

PPPoEThe discovery phase of the dialing (Discovery):The discovery phase of PPPoE is divided into 4 steps. respectively: PADI (PPPoE active Discovery Initiation) Pado (PPPoE active Discovery offer) Padr (PPPoE active Discovery Request) PADS (PPPoE Active Discovery session-confirmation). When these four steps are completed, both the user host (PC) and the Access Concentrator (AC) will be able to learn about each other's unique MAC address and unique ses

, statistics and billing, IP Address Allocation (allocated when dialing) ◆ point-to-poi in PPPoE The abbreviation of nt protocol over ethernet allows an ethernet host to connect to a remote access concentrator through a simple bridge device. ◆ Using PPPoE protocol, remote access devices can control and charge each access user ◆ it is widely used in a series of construction projects such as community networking, currently, the popular broadband access

management-basically software-driven-was also involved at Interop. For example, PowerCloud introduced how its technology enables OEM partners to manage cloud-based wireless access points at the venue. As a result, managed service providers can compete positively with companies such as Aerohive and Meraki. By adding a small amount of code to their firmware, the access point can "call" the host service and connect to a specific customer with a unique i

to the central controller through the Cisco hybrid remote edge Access Point H-REAP. The architecture of Aruba is similar to that of Cisco, but it only adjusts the access point so that it can make forwarding decisions in the branch. The Aruba Mobile Virtual Enterprise MOVE architecture allows branches to have up to 16 independent access points, one of which acts as the controller of the Branch's wireless network. "Aerohive has fewer controllers, and Meraki
