When MAC defines Network Topology

100% accurate Network Topological information is the DNA of any big decision making in Telco sector. In many Telcos in the Globe, Fiber concentration is not still upto the benchmark and still can not go for one hop or two hops MW solution. Long MW chains and Mesh MW network carry the 2G/3G/4G services where defining the dynamic E2E service path is a big challenge for the Operators. Operators depend on manual database for the above cases which can not give 100% accurate information and that has impact finally on financial part also. The concept of service MAC and ARP can resolve the problem. This AI based automated database system can maintain and ensure 100% accurate database of network wide E2E sites’ travelling path, number of sites per microwave link, number of sites dependent of node sites, link capacity utilization without any manual intervention. Fully automated ??

How MAC/ARP concept can solve the problem?

The address resolution protocol, or ARP, connects an always-changing IP address to a fixed media access (MAC) address. A directory holds a detailed map of both IP addresses and MAC addresses.

What is ARP?

Every device within a local area network (LAN) has two addresses. One changes (your IP address), and one is fixed (your MAC address). ARP keeps those two systems connected.

The ARP process involves translation. For example, your IP address may be quite a bit shorter than your MAC address. And they're never made up of the same numerals in the same order.

But if a system can't resolve one to the other, data can't flow between devices. Quick translation is critical.

How does ARP work?

A piece of data arrives at a network gateway, and it needs to connect with a machine within the LAN. ARP helps the data arrive at the right place.

The ARP protocol leans on:

• MAC address. Also known as the data link layer, the MAC address connects two devices and allows them to transfer information.
• IP addresses. When a new device joins a LAN, the system assigns an IP address. Periodically, the system randomizes and assigns new IP addresses to protect user privacy. An IP address facilitates packet forwarding through routers.

The following steps take place during the ARP process:

• Arrival. Data is destined for a machine on the LAN, and it lands on a piece of hardware within the network.
• Check. The gateway machine asks the ARP program to find a MAC address that matches the IP address specified in the data packet. ARP uses a simple message format with a size that can vary.
• Specification. When the lookup is complete, the gateway machine releases the information, and the data moves ahead.
