Cloud computing and the Big Data Era Network technology Disclosure (11) Data Center Interconnection

Data Center Interconnect-a wider two-tier network

This chapter introduces the multi-tier network interconnection technology across data centers, including requirements and business models, highlighting traditional vpls scenarios and emerging OTV scenarios.

Figure Vpls the Network Diagram

The core device is PE, is responsible for the CE access VPLS network

At the same time, end the Vpls tunnel and enter the MPLS+IP core network

Figure OTV the Network Diagram

Through the Otv Gateway, a multi-tier network with control planes is built across the WAN

Diagram Data Center interconnection of several layers

Lisp+otv is the perfect combination.

Lisp separates the identity and location information at the internal communication level, ensuring that the IP of the communication machine is not changed across the data center VLAN

OTV creates a sophomore network reliable link channel outside the data center

NSX is VMware's network virtualization platform for virtual machine image drift and business recovery under fault
