Bridge and Routing Basic training
Dear all hand
Sometime we very confuse with computer network terminology specially for someone that never has ‘academically contact’ with this field. So in this post I intended to give us clear understanding about the difference between bridge and routing.
Bridge Function
Perhaps those of us who are not familiar with computer networks to wonder whether it is bridged?. Bridge used to combine two or more ethernet interface type, or the like, so that seems to be in a same network segment. Activate the bridge on the two interfaces will disable the routing function between the two interface.
Therefore some people prefer to use the system on a wireless network bridge them, because:
More easily made. Moreover, wireless devices generally do not support routing.
Below is sample image of a bridge :
Weaknesses bridge system:
- It is difficult to regulate broadcast traffic (eg due to a virus)
- Problems on one segment will create problems in all segments on the same bridge
- It is difficult to make a fail over system
- It’s hard to see the quality of the links on each segment
- Traffic load on each device through which will be heavy, due to the accumulation of traffic.
Routing definition and function
Routing is actually a point settings on the data packet routed network. Routed Network that is, setting the path between network segments based on the destination IP address (or too long), the OSI network layer. Each network segment typically has a network subnet (IP address) is different.
Routing allows us to monitor and better network management. More secure (firewall filtering easier and complete). Broadcast traffic is concentrated in each subnet. It takes a wireless device that is able to do a full routing, or adding a router in the BTS. For large scale, can be used Dynamic Routing (RIP / OSPF / BGP).
Below is sample image of an Router:
Router type
In general, the routers are divided into two types, namely:
- static routes (static router): the routing information is created manually by the user to set the direction in which certain traffic will be routed. Default route is one example of static routes.
- dynamic routes (dynamic router). that will be created automatically: when adding an IP Address on the interface routing information obtained from dynamic routing protocols like RIP, OSPF, and BGP
