Switch Market Opportunities

GE to Desktop: FE port evolved to GE port, good opportunity for
GE and 10GE devices

Layer 3 to Edge: the access device with L3 feature can meet the
requirements of network intelligence and security

Ethernet network position migrated: matured in LAN, rapid
growth in MAN, migrating to WAN gradually

Intelligent network: highly sensitive to services, high security

QinQ

-
Easing the increasing deficiency of
public network VLAN ID resources;

-
Users plan private VLAN IDs and will
not conflict with public network VLAN
IDs;

-
Providing small
-
sized MANs or
enterprise networks with a relatively
simple layer 2 VPN solution.

2. Selective QinQ

-
External VLAN tag can be encapsulated
according to different users, services
and priority levels.

-
Implement different bearer solutions for
various services.
