摘要：The traditional network of TCP or UDP, make use of static switches, i.e. load balancing across paths which is derived by calculation of hash packets. Concerned issues with this approach are that each packet of such a flow goes in a solitary pre - characterized way through the network. In the case of any disparity in the path, either a switch breakdown or physical layer harm, bundles tend to lose or the other switches need to be manually configured for selecting a different path. This becomes a herculean undertaking, as the system develops. Likewise, the disservice of hashing is that all connections get the equal percentage of hash values or to say, all paths own the same capacity (ECMP - Equal Cost Multi - Path). Eve n if the network is coded strongly to work in as multipath networking, because of the identical capacity issue. Therefore, optimal load adjusting won't not be accomplished. An optional answer for this issue is Software Defined Networking (SDN). SDN is an i dea where the central controller takes the choice for parcel traversal and not the switches. Controller automatically distinguishes the topology by listening to the switches and ascertains path with lesser load. Controller then directs the switches with mo ving entries further needed for the paths thus optimally balancing the load with every flow
