PPT-Coping with Link Failures in Centralized Control Plane Arch

Maulik Desai Thyagarajan Nandagopal Introduction Traditional network Router identifies link failures and establishes alternate route Centralized control plane architectures SoftRouter. Class 2. Types of Networks. ISP Networks. Entity only owns the switches. Throughput: 100GB-10TB. Heterogeneous devices: laptop/desktop. Medium latency: 20-80 milliseconds. Enterprise Networks. One entity owns many of the servers + switches. Network Connectivity. Junda Liu, Scott Shenker, Baohua Yang. and Michael Schapira. junda@google.com. Control Plane. Data Plane. ?. Control Plane.
