Bridging Your World with L2

Layer-2 bridging works by putting one physical and one virtual Ethernet adapter into a mode where they can receive traffic that is not destined for their address. This traffic is selectively sent onto the other network according to the IEEE 802.1D standard, known as, "bridging" the frames.

A bridge connection is a network connection that allows several devices to communicate with each other as if they were on the same physical network, even if they are connected to separate networks. For example, your laptop may be connected to Wi-Fi while your desktop computer may be connected to a wired network.

Layer 2, also known as the Data Link Layer, is the second level in the seven-layer OSI reference model for network protocol design. Layer 2 is equivalent to the link layer (the lowest layer) in the TCP/IP network model.

A bridge is a network device that connects multiple subnetworks to create a single network. It provides interconnection with other computer networks that use the same protocol. Through a bridge, multiple LANs can be connected to form a larger and extended LAN.

It is a cross-chain bridge that allows users to transfer tokens between supported blockchains. Tokens are deposited on the source chain and “representation tokens” are minted on the destination chain. Deposited tokens are not precisely locked and can be used in DeFi protocols by Orbit Farm.

There are four types of network bridging technologies: simple bridging, multiport bridging, learning or transparent bridging, and source route bridging. A transparent bridge uses a forwarding database to send frames across network segments.

Bridges are used to improve network performance, reduce traffic, and extend the reach of networks. They function by filtering traffic and forwarding data based on MAC addresses.

What is layer 2 in 5G? ›

MAC, RLC, PDCP, SDAP of 5G-NR |Layer 2

Media Access Control (MAC) layer. The 5G Media Access Control (MAC) layer, residing in Layer 2, plays a pivotal role in managing radio resources and ensuring efficient communication.

Complexity: Implementing and maintaining Layer 2 solutions can be complex, requiring additional development and testing efforts. Limited Adoption: Layer 2 solutions are still in the early stages of adoption, and not all applications or users are familiar with their functionality.

LAYER 2 NETWORKS

A switch works with MAC addresses at layer 2 of the OSI 7 layer model. Devices used on a Layer 2 Ethernet network include network interface cards, hubs, bridges and switches. Ethernet devices use 'burned in' MAC addresses to identify each host.

Bridges are used to extend the range of the network by connecting two or more physically separated segments. Bridges provide security as it separates different parts of networks from each other. Bridges provide network redundancy by connecting two or more paths between different network segments.

Routers and bridges differ in several ways. First, routers can connect different networks, while bridges can only connect segments of the same network. Second, routers use logical addresses, while bridges use physical addresses. Third, routers can handle different network protocols, while bridges can only handle one.

Bridges as a function are definitely still around. Simply speaking, as a function of separating the collision domain, a switch is a bridge with lots of ports. For an example of bridging two network media types, access points are bridges that bridge 802.11 traffic to Ethernet.

Layer 2 switches offer limited to no routing capabilities within network segments such as VLANs. Layer 3 switches offer routing between different network segments. Limited scalability. Higher scalability enabled by layer 3 switches' cross network segment routing capabilities.

Layer 2 of the OSI model is known as the data link layer. The Layer 2 protocol you're likely most familiar with is Ethernet. Devices in an Ethernet network are identified by a MAC (media access control) address, which is generally hardcoded to a particular device and doesn't normally change.

Layer 2 scaling solutions play a pivotal role in overcoming the scalability challenges faced by blockchain networks. By offloading transaction processing to offchain networks while maintaining the security guarantees of the main chain, L2 solutions enable faster, cheaper, and more efficient transactions.

Layer 2 of The OSI Model: Data Link Layer provides the functional and procedural means to transfer data between network entities and to detect and possibly correct errors that may occur in the physical layer.
