single route broadcast frame and All-route broadcast frame.
Hello Friends, In this blog post(single route broadcast frame and All-route broadcast frame) we are going to share some knowledge about What is a broadcast frame? What separates broadcast domains? Does the router forward the broadcast packet? What is broadcast routing in computer networks?
What is a broadcast frame?
A broadcast frame is a specific frame that is delivered to each device in the LAN.
This broadcast frame has a specific address. The main purpose of the broadcast frame is to find out the service discovery and DHCP.
What separates broadcast domains?
In the computer network, any device or computer can be considered as the broadcast domain which is connected with the same switch and repeater.
The network device router separates the boundaries of this broadcast domain.
Does the router forward the broadcast packet?
No, the Router does not broadcast the packet by default with an IP broadcast address.
Rather protocol used within the broadcast packet is used or operates within the single broadcast.
But some special configuration routers can be configured to do this.
What is broadcast routing in computer networks?
Broadcast routing is concerned with the sending of data packets by the router to each and every host in the network one by one.
The router creates the broadcast domain but in some special cases, it can be configured to forward the broadcast in the network.
Single route broadcast frame:
For determining the path a station sends a frame to another.
An approach to route discovery has the sending station transmit a single-route broadcast frame.
Similar to the all-route broadcast frame, it contains no routing information.
At this time, instead of broadcasting to all LANs, each bridge forwards a frame only through a port that is part of a spanning tree.
In this case, the destination receives only one request.
However, instead of relying on the spanning tree’s route, the destination station sends an all-routes broadcast frame as its response.
Eventually, the source station receives many responses, one for each route, and, as before, can choose the one it wants for subsequent frames.
The advantage of this method is that there are fewer frames traveling from source to destination.
The disadvantage is that the bridges must determine the spanning-tree list.
All-route broadcast frame:
The bridges must help by executing a variation of the flooding algorithm to make sure the request and responses are received.
The determination of the route to the destination is called route discovery.
One method to do this is to send an all-routes broadcast cast frame to the intended destination station.
The frame’s control field specifies the frame type and notifies the bridges that they should forward the frame onto all available LANs.
To avoid propagation, a station sends an all-routes broadcast frame with the route designator fields empty and the control fields routing field length equal to 0.
When a bridge receives the frame, it inserts its own and the incoming LAN’s IDs into the routing field and increments the routing field length.
To avoid forwarding a frame it received previously, the bridge examines the existing route designators.
It will not forward a frame to a LAN whose ID was part of a route designator of the incoming frame.
