IP Network Development

Service oriented, improve quality of service,

strengthen network profitability, migrating into

multi-service IP network

Increasing subscriber and bandwidth

requirement, demand larger IP network

size and traffic Enterprise customer is moving towards IP

network service, require ISP to provide

carrier class quality of service. Network and services continues to

grow;IPv6 technology mature and applied Network equipment must improved to suite

for ever increasing services
