RDMA based IP routing protocols and router architecture
MetadataShow full item record
The Ethernet technology has advanced from the era of fast Ethernet to the era of gigabit ethernet. The gigabit routers currently available in the market are employing expensive hardware based implementations for improving the throughput , which makes the overall cost of the device prohibitively high. In this thesis the author reviews the existing router architectures and routing protocols and critiques the shortcomings of the existing implementation. This thesis evaluates the drawbacks in the existing infrastructure and proposes an architecture that provides a solution based on the RDMA protocol. The proposed architecture uses the RDMA protocol for transferring the data payload from the ingress interface to the destination interface. In this research the author also presents an analytical mathematical model that can be used for calculating the delay incurred by a packet, memory utilization and CPU utilization for both architectures. The potential benefits by the use of RDMA protocol are also explained in detail in this thesis. The necessity for modifying the update packet structure in the existing implementation of RIP is discussed in detail. Packet payload handling in both architectures is compared and the advantages in the RDMA protocol based implementation are presented.
