It is a dynamic vector routing algorithm.
consists of data structure called routing tables.
it calculates the best route based on the distance.
Distance vector routing updates full routing table.
The utilization of CPU and memory in distance vector routing is lower than the link state routing.
Bellman -Ford algorithm is used for performing distance vector routing.
LIMITATIONS
It is slower to converge than link state.
it creates more traffic than link state since a hop count change must be propogated to all routers and processed on each route.
The bellman-ford algorithm does not prevent routing loops from happening and suffers from the count-to identify problem.
In such such a scenario 3 hop-counts path will be selected although other path is congestion free. This can be overcome by using LSA .
(Link State Analysis) protocols and Hybrid Protocols. In these not only the hop-count is considered but also link quality is checked at regular interval to ensure the selection of not only shortest path but also the most efficient path for the destination

Distance Vector Routing Definition. Distance vector routing is a simple routing protocol used in packet-switched networks that utilizes distance to decide the best packet forwarding path. ... A hop is the trip that a packet takes from one router to another as it traverses a network on the way to its destination.

Hi , I need help form u. I need information about Cloud storage.As a test engineer how can i test the cloud storage. what i need to learn before going to test the cloud storage application. These are the some of the Questions related to Cloud Storage. 1. What is meant by Cloud Storage? 2. What cloud storage Requires? 3. What factors should you consider before implementing cloud storage? 4. How do Private storage clouds compare with large commercial cloud service offerings? 5. Where to use Public Cloud storage? 6. Where to use Private Cloud storage? 7. Where exactly the cloud storage will be used? 8. Cloud storage means Maintaining the data some ware in server or what? If they Maintain data where it will save? 9. In which Environment the cloud storage can be developed? 10. Is the Cloud storage support XP OS? 11. Up to what extent the tester should know about cloud storage to test the storage part? Mainly send me the details how testers are going to test the Cloud storage application. ASAP.....
