ZXR10 5900 5200 Product Description
and copy 802.1p field of inner label to the outer label to keep the continuity of customer
QoS.
SVLAN has enhanced function of network user location, which enables QinQ to better
support PUPV (one VLAN per user) and PSPV (one VLAN per service). It is easy for
carrier's operation and maintenance management. The most typical application is Triple
Play service in broadband to the home.
SVLAN can perfectly solve the problem of user location separation and service
differentiation in broadband network. It can implement operation and maintenance
management for one VLAN per user, which brings great convenience to network
management and maintenance. ZTE is always an advocator of this technology and
takes the leading position in the industry.
ZXR10 59/52 series switch supports SVLAN with the following applications and
functions:
Being able to distinguish different service VLAN at one port and tag different outer

layer label based on different service requirements.
 Being able to implement coexistence of VLAN transparent transmission and QinQ
service at port. Being able to keep user label unchanged without adding new label
to user label when some VLAN packets are going through switch.
 Being able to duplicate 801.1p field in user label to outer layer label to guarantee
that user's service level is kept unchanged in QinQ network so as to keep the
consistency of QoS of user service.
In IEEE802.1ad, S-Tag is for 0x88A8-type Ethernet, and C-Tag is for 0x8100-type

Ethernet. ZTE switch supports any C-Tag and S-Tag Ethernet.
SVALN has two major applications in the network:
SVLAN is applied in user location separation and service differentiation in network and
Triple Play service in family broadband. SVALN QinQ can solve traditional 4096 VLAN
resource shortage problem so as to truly implement PUPV and PSPV.
