Local bypass

What does Local bypass mean?

In computer networking, a local bypass is a Technique that allows a local device to connect to a remote network without going through the default gateway. This can be useful for performance reasons, as it can reduce the latency and improve the overall speed of the connection. It can also be used for security reasons, as it can prevent unauthorized access to the local network.

Local bypass is typically implemented using a layer 2 switch or a router. The switch or router is configured to allow traffic from the local device to bypass the default gateway and go directly to the remote network. This can be done using a variety of different methods, such as VLANs, ACLs, or static routes.

Applications

Local bypass is used in a variety of different applications, including:

• Performance: Local bypass can be used to improve the performance of a local device by reducing the latency and improving the overall speed of the connection. This can be important for applications that require real-Time or near real-time data, such as video conferencing or Online gaming.
• Security: Local bypass can be used to improve the security of a local network by preventing unauthorized access to the network. This can be important for networks that contain sensitive data or that are subject to regulatory compliance Requirements.
• Cost: Local bypass can be used to reduce the cost of a network by eliminating the need for a dedicated gateway. This can be important for small businesses or organizations with limited budgets.

History

The concept of local bypass has been around for many years. However, it was not until the advent of layer 2 switches and routers that it became a practical reality. Layer 2 switches and routers allow for the creation of virtual LANs (VLANs), which can be used to isolate different parts of a network from each other. This makes it possible to create a local bypass that allows devices on one VLAN to connect to a remote network without going through the default gateway on another VLAN.

Local bypass is becoming increasingly popular as a way to improve the performance, security, and cost of networks. As layer 2 switches and routers become More affordable and easier to use, local bypass is likely to become even more widespread in the future.
