4.3 Multi-Service Carrier VLAN Solution
 Note:
Only S3100-EI series Ethernet switches support this multi-service carrier VLAN
solution.
With development of various application technologies, enterprise users are
increasingly relying on network services. They hope the networks can offer secure,
reliable leased lines, VOIP and video conference services, thus reducing their
operating costs. Additionally, apart from simple Internet surfing, individual users expect
more abundant services from the networks, e.g., IPTV, video chatting, real-time gaming,
etc. Meanwhile, construction of the NGN/3G carrier network will draw huge attention of
carriers. If NGN/3G services can be carried on the broadband access network, the
costs of the entire network solution can be lowered dramatically.
To carry such services with different QOS requirements, the broadband access network
needs to have effective service identification and isolation capacity. VLAN is the best
service identification and isolation technology at present, and is the basis for
