Harbin Cable Radio And Television Broadband Integrated Information Network Of The Overall Design And Technology

It is necessity trend for the developing of Broadcasting & TV industry that Broadcasting & TV integrated information network will face more operation , It is not only extend it抯 span of operation , but also make the best of Broadcasting & TV抯 advantage to offering public more information service . Harbin Cable Broadcasting & TV broadband integrated information network should be a telegraphic quality broadband network , that have the capability to transport abundance high speeding information in order to meet the increasing date stream in it. This network adopt DPT (Dynamic Packet Transport) to construct it抯 backbone ring net , In order to provide all multimedia transmission services including video ?voice , data etc at one time And sustain all sorts popular networking protocol , The design adopts many type of accesses to meet different user抯 requirements. MPLS (Multiprotocol Label Switching) is recognized optimal technokgy in backbone IP network at present, It makes layer3 with IP routin~adcfressing combined with layer2 with high speed data switching in a n~work ; It makes IP network without linking realized all sorts of applications with linking.
