Virtual network routing in cloud computing environment
2016 International Conference on Computer Communication and Informatics (ICCCI)
Cloud computing offers on demand services, accessing and availability of resources by means of multiple devices by speedy detecting as required. In cloud computing data centers are consider as a virtual servers and organization or single users pay as the capacity they use (eg:Amazon web services).data centers offers an cloud services by use of virtualization techniques. Compute, network, storage are the principle offering of information facilities. . In networks the data lookup may degrade the
... etwork transparency so the importance of the routing is considered as an essential part in the cloud computing since they are based on the on-demand networks. Thus the comprehensive way of different types of routing algorithms in cloud computing environment is surveyed. Here we have compared routing in structured and unstructured overlay network. Increasing Dimensions. Multiple realities. RTT-weighted routing D) Tapestry: Tapestry  is a peer to peer overlay routing infrastructure, helps in offering location-Independent, scalable and efficient routing of messages using only local resources. Each node maintains its routing table which consists of set of neighbouring nodes. When a node routes an incoming message, the node selects the next hop node from the neighbours by matching the level prefix which is similar to the longest prefix routing method. As a result the ID"s of the node on a route vary gradually12]. Unstructured overlay network: Unstructured is a decentralization approach and it"s not distributed system. Some of the protocols used in this network such as free net, Gnutella, Fast Track, Bit Torrent, Over Net/eDonkey.These methods are inefficient between topology and data location lookup  .
