According to one embodiment of the invention, AT can be arranged in other fields of IPV6 packets, for example extension header
In.AT can also be arranged in the destination address in IPV6 data packet heads or source address chooses continuous in IPV6 address fields
Bit.
Fig. 3 is the schematic diagram of an application scenarios of the method that data distribution is realized according to the home gateway of the present invention.Such as
Shown in Fig. 3：IPTV set top box 32 can obtain AT for " own business/IPTV " address prefix is in IPTV load planes
Corresponding address prefix establishes backhaul route.Equally, home gateway 31 can also be obtained before the address that AT is " home broadband "
Sew, and be that corresponding address prefix sets up backhaul route in the Internet bearer plane.
Home gateway 31 is integrated service home gateway, can support the access to multiple business, such as broadband access network industry
Business, IPTV service, VOIP business etc..Now, the physical port that IPTV set top box 32 is connected with home gateway 31 had both been included
IPTV video flows, also comprising Internet internet traffics.The flow of different business attribute needs to give into different networks
To ensure respectively.For example, IPTV video flows enter IPTV load planes, i.e. IPTV networks by business router SR, enter
Row transmission, and the internet traffic of IPTV set top box 32 then still enters the Internet bearer plane, i.e. Internet, carries out
Transmission.Accordingly, it would be desirable to carry out shunting transmission to both flows in home gateway 31.
The AT that destination address in the IPV6 data packet heads that the parsing set top box 32 of home gateway 31 is sent is included, when AT marks
Type of service be IPTV service when, this IPV6 packet is sent to IPTV networks by home gateway；The service class identified as AT
When type is broadband services or VOIP business, this IPV6 packet is sent to Internet by home gateway.
According to one embodiment of present invention, home gateway configuration local policy routing table；Wrapped in local policy routing table
Include：IPV6 address prefixs comprising AT and next-hop route, be [ATaddress, next hop].For example,
[*****00001001****,2001:c68:300:102::2]
For the up IPV6 packets of each arrival home gateway, AT fields that can be in searching data bag, and with
Policybased routing table is matched.If finding corresponding route entry, corresponding Service Gateway is routed to.For example, right
It is transmitted in IPTV video flow by IPTV load planes, and passes through Internet service for the flow of broadband access network
Plane is transmitted.
According to one embodiment of present invention, because the IPV6 prefixes that IPTV terminal is obtained are that AT is " IPTV service "
IPV6 prefixes, and it is " home broadband " flag that the route set up in the Internet bearer plane by wideband switch-in business, which is AT,
Prefix.Therefore, should be in family in order to be route in by the internet traffic of set top box according to the Internet bearer plane
Prefix conversion is carried out in gateway.
It is each mapping for needing the STB terminal changed to set up in an address mapping table in home gateway
Relation, the address of cache is the mapping based on address, i.e., only carry out at the address of cache of IP aspects, the conversion that port aspect is not done
Reason.For example：
[IPTV address1,src_address1,lifetime]
[IPTV address2,src_address2,lifetime]
...
[IPTV addressN,src_addressN,lifetime]
Wherein, IPTV address refer to the IPV6 addresses that STB terminal is obtained（AT fields are IPTV identifier words
Section）, src_address is to refer to the set top box broadband services address pool address after conversion, the address prefix and home network
The address prefix of acquisition is consistent（AT fields are wideband switch-in business field）, lifetime is life cycle, is effective
Time.
It is that the packet that IPTV identification services are identified is required to carry out to AT fields in source address for up packet
Prefix maps.Concrete mode uses a not currently used broadband access to search currently available broadband access address pool
Address is mapped as the address after conversion.Address of cache is only done in the mapping, does not do port mapping, therefore will not introduce volume
Outer checksum such as recalculates, is segmented at the operation, it is not required that record session record.
For descending IPV6 packets, it is necessary first to search whether destination address is located in address mapping table.For mesh
Address can then carry out prefix replacement by the packet of address completely in match address mapping table, the route for otherwise carrying out routine is looked into
Look for.
According to one embodiment of present invention, judge for IPTV strategy of the IPTV upstreams based on AT, read AT fields
Configuration implication, and based on the field for uplink traffic destination address carry out policybased routing control.It is for AT fields
The flow of " IPTV service " carries out forwarding operation according to default route, for the flow that AT fields are " Internet service ", then sentences
Whether the disconnected flow has established corresponding mapping item in prefix mapping table.If having established mapping item, execution is looked into
Table handling, find matching list item and conversion after source address；If not yet setting up mapping item, lookup broadband is needed to connect
Enter the currently available address in address pool, selection available address is set up before " IPTV service address " and " internet services address "
Sew mapping item, and corresponding prefix mapping is carried out to packet and handle.
For the descending internet traffic of arrival, first have to search address mapping table, judged based on destination address.
If finding complete matching in the mapping table, prefix conversion process is carried out；Otherwise common routing forwarding operation is carried out.
