Network Basics for CC
Network Architecture for Virtualization
Traffic on virt network
North-South Traffic
East-West Traffic
Basic Net Concept
Route and Default Gateway
VLAN
Broadcast & Unicast
Network Features of Huawei Products
Traffic flow
VM run on the same host and port group
VM run on diff host but same port group
VM run on the same host but diff port group
Multiple DVS run on a physical host
Security Group
A logical group that consists of same security requirements
Deleting a security group does not affect the rule. Deleting a rule will affect the security group.
Virtual Switching Mode
SR-IOV Mode
User Mode
Common Mode
Virtual Networks in Virtualization
Network Bridge Function
MAC Learning
Packet Forwarding
-When the virtual NIC is connected to a port of the switch, the virtual NIC and the network bridge, with the same IP address configuration, communicate with each other in broadcast mode.
-When the virtual NIC is connected to a port of the router, the virtual NIC and the network bridge are configured with IP addresses that belong to different IP address ranges.
virtual switch
is used for VMs to communicate with external networks and acts as an upgraded network bridge
Physical Network in Virtualization
Network devices : Router, Layer-3 switches, Layer-2 switches, server NIC
:check:
Layer-3 Switch
-high speed data exchange
-mainly used in LAN
-better performance (same data flow is forwarded without routing again)
:check:
Router
-connect the intranet to Internet.
-maintain a route table for route addressing.
-used in WAN
-low efficiency (delay)

Storage Traffic
Management Traffic
Service Traffic
LACP
: Increased bandwidth, high reliability, load balancing
