In this article, we will talk about the much-asked query of what is layer 2 network is and how its works in a typical network. We will also briefly touch on the basic concepts regarding this topic. The data link layer of the OSI model is sometimes called the MAC layer. It's ...
还有其他大家不可能没听过的名字:Starknet,Arbitrum One,Base,Boba Network 状态通道 状态通道是Layer2的入门级方案,状态通道是交易双方在链下构建一个通道,通过私钥签名以后,在链下进行交易。状态通道是一种扩容(scale up)的手段。 状态通道也称为支付通道,支付通道是如今最广泛采用的 Layer 2 方案。例如,闪电网络...
Layer 2 encryption secures information at the data-link level as it is transmitted between two points within a network2 .Challenges with Unencrypted Network DataCybercriminals can “eavesdrop” on unencrypted data traveling over a network. This compromises privacy and makes it possible for these ...
the primary function of the network layer is to move data into and through other networks. Network layer protocols accomplish this goal by packaging data with correct network address information, selecting the appropriate network routes and forwarding the packaged data up the stack to the transport l...
What is a Layer 3 Switch A Layer 3 switch operates at both Layer 2 (data link) and Layer 3 (network) of the OSI model. It combines the MAC address switching of Layer 2 with IP routing capabilities, allowing it to manage traffic between subnets or VLANs without a standalone router. Ho...
L2TP can transfer most L2 data types over anIPor Layer Three (L3) network. The process initiates a tunnel between an L2TP access concentrator (LAC) and an L2TP network server (LNS) on the internet. This facilitates a Point-to-Point Protocol (PPP) link layer that is encapsulated and transfe...
switch is a type of network switch or device that works on the data link layer (OSI Layer 2) and utilizes MAC Address to determine the path through where the frames are to be forwarded. It uses hardware based switching techniques to connect and transmit data in a local area network (LAN...
Layer 2 - Data link layer The data link layer is like the network layer, except that the data link layer facilitates data transfer between two devices using the same network. In the data link layer, packets are broken into pieces referred to as frames. Similar to the network layer, the...
1. Physical Layer The Physical Layer is responsible for the physical connection between devices. It defines the hardware elements involved in the network, including cables, switches, and other physical components. This layer also specifies the electrical, optical, and radio characteristics of the netwo...
Media Access Control (MAC address orLayer 2addresses or physical address or hardware address) addresses are 48 bit (six bytes)binary addressesrepresented inhexadecimals. The purpose of representing thebinary addressinhexadecimal formatis to make it easier for humans to read and understand. MAC addres...
