Solutions on floor 2 are a critical part of the network virtualization. Here’s a detailed explanation:
What is the layer 2?
In computer networks, layer 2 refers to the model model data layer (L2). It works on a physical layer and does not provide errors, reliable and fast transmission between the network device.
The Stak L2 protocol consists of two floors: Mac (media access control) and CSMA/CD (carrier -sisted multi -approach/circle reduction). Mac Sublayer is responsible for sending and receiving data data frames, while the CSMA/CD -Alblayer offers mechanisms to detect and correct errors.
What are the solutions of layer 2?
Floor 2 solutions are designed to improve network reliability, scalability and performance by providing additional protection, dismissal and tolerance for errors. These solutions usually include adding a new layer between the bundle of L2 protocol and the rest of the model.
There are several floor solutions 2:
- Frame Relay : An owned circle that provides guaranteed permeability and delivery without errors.
- ATM (asynchronous transmission mode) : switching technology that uses multiple frames to provide information at high speeds.
- Bulls/SDH (Sinchron Digital Hierarchy): Digital Signal Processing Protocol used to move the network over a long distance.
Why do we need floor solutions 2?
Networks are prone to failures, errors and losses of packages for many reasons such as:
- Restrictions on Physical Media
- Network congestion
- Invalid or damaged equipment
Solutions on layer 2 help to relieve these questions:
- Redundcy
: Providing multiple data routes by ensuring that the network remains functionally even if it is down.
- Error tolerance
: automatically detecting and correcting errors without the lack of human being.
- Better reliability : Reducing and loss of packaging delay.
Examples in the real world
Some of the usual floor 2 solutions are:
* Frame connections (eg T1, E1) for high speed network connections
* Distributed switch solutions (eg. Cisco Switch Catalyst) Improved scale and performance in data centers
* Network routers with constructed connecting features (eg Juniper Networks SRX Series) Layer 2 for protection and optimization.
In short, layer 2 solutions are designed to improve network reliability, scalability and performance by providing additional protection, redundancy and tolerance for errors. These solutions help to relieve challenges related to online errors, errors, and packages, ensuring that networks remain in operation even in harmful conditions.
