Chap1 Context-

Data center History : data and storage networks-from centralised to cloud networking Virtualisation  principle of containers versus virtual machine-levels of virtual communications-specificities of L 2  virtual communications MAC addressing and extended VLAN segmentation  L3 virtual communications addressing, IP floating .

Chap2 Data Center Architecture

DC Network. Network Element Architecture- Isolated processes: Routing and Switching- Integrated processes: Flow switching- Separated processes Hardware design-Multistage Fabric Software design-SDN concept

 Performance of Communication Architecture-Limitations- Congestion management principles- Traffic management principles

Chap3 Data center Communication

 Topology types big switch, clos network fat tree-main communication protocols- Routing and Topology-Problems and New solutions for DC-Hierarchical L2Routing with Pod and pseudo addresses- L3 routing on pseudo IP addresses

Infrastructure Standardisation TIA942 standard elements-Redundancy and reliability levels-Rated (tiers) DC --Data Center Bridging  standards- Enhanced Ethernet flow control and congestion management. PFC,ETS,CN,DCBX

Chap4 Load sharing

Principles of load sharing: Load sharing objective, levels and processes: discovery, distribution, type of distribution: traffic independent, traffic dependant, load dependant

Chap5 Reliability

Introduction : Failure characteristics, Fault handling strategies, protection and restoration

Failure recovery for routed network: Recovery methods in MPLS-TE, recovery cycles : rerouting and protection switching, local versus global strategies, bandwidth sharing versus protection ; Fast reroute Mechanism – overview , types of protection; detour and bypass illustration,  Signalling

Failure recovery for bridged  networks: EPRS
