Cloud computing has brought unprecedented challenges to data center networks, which are mainly embodied in network scale, resource virtualization and sharing, and distributed data Center collaboration. First look at the network scale. Cloud Computing Data Center Server size is usually thousands of units, or even tens of thousands of units, and with the development of the business, the scale of the network will continue to expand, with the attendant, cabling network management has become more complex. The traffic flow model is no longer the traditional north-south oriented, high convergence ratio, but with hado ...

The switch occupies an important position in the enterprise network, which is usually the core of the whole network. In this era of hacker intrusion and virus-ridden network, as the core of the switch is also taken for granted a part of the responsibility of network security. Therefore, the switch must have the professional security product performance, the security has become the network construction must consider the heavy middle. As a result of security switches, the integration of security certification in the switch, ACLs (Access control list), firewall, intrusion detection and even anti-virus functions, the security of the network really need ...
Hyper-V is the new concept of a recently virtualized network, with news that many of its most recent features affect network design. In previous articles, we briefly described some improvements in network virtualization and some improvements in virtual machine networks. This article introduces another network improvement: Network card Aggregation (NIC teaming), and a brief introduction to some of the new Hyper-V options for data center design. Network card aggregation is also called load balance failover (load balancing Fail over ...)
