Description
Technical field
The present invention relates to access networks.
Background technique
Access network operator is just gradually developing on the direction of virtual residential home network gateway function.Such as Fig. 1 institute
Show, virtual residential gateway vRG is designed to handle both user's control plane and user data plane in a manner of virtualization:
Control plane: the control plane protocol of LAN side and WAN side requires to be handled by vRG, these agreements are for example
It is IP forwarding (Dynamic Host Configuration Protocol server, dhcp client, ARP, ICMP, pppoe client etc.), NAPT (PCP, IGD, DMZ, UPnP
Deng), TR-69, VoIP etc., NAPT agreement mainly meets the needs of IPv4, and can also meet IPv6 and provide simple safety
The needs of property means.
Data plane: the forwarding of IPv4/IPv6 user data packets, for NAPT, QoS, VoIP of IPv4 etc..
VRG needs for all information (intelligence) present in home networking gateway to be moved to the outer of home network
Portion, and in these information of network-side virtualization.This virtualization is mainly driven by following factors:
The saving of-OPEX (operational overhead).Since each residential home gateway is only equipped with the letter of such as Ethernet exchanging
Single function, thus the cost of gateway is very low, to reduce the totle drilling cost of the access network comprising hundreds of gateways.
Dispose the flexibility of new business --- the advantage of the marketization in time.It, should if necessary to dispose new business/strategy
Business/strategy can in vRG rather than realized in residential home gateway.Business/strategy is disposed relatively more in vRG
Fastly, and it is lower than updating all residential home gateway costs, therefore the business/strategy can be within shortest deployment time
It launches.
To the less-restrictive of technological evolvement (for example, agreement etc.) --- it is efficient on the time.VRG usually has very strong meter
Calculation/processing capacity, thus it is easily scalable to support new agreement.Traditional residential home gateway does not simultaneously have this expand
Malleability, therefore be difficult to be upgraded to support new agreement.
Summary of the invention
In existing virtual residential gateway solution, vRG is embodied as the server capability of centralization (in home network
Close device external), manage both user's control and user data packets processing.However, data plane functions but consume greatly
Energy-handling capability.Due to its be it is centralized, this be likely to become user data service processing main bottleneck.For example, in vRG
Execute 3/ layer of 4 packet-processing functions of layers such as network address translation, interblock interference, firewall.Therefore, vRG must have non-
The processing capacity of Chang Qiang great is to support these functions.In the case where the scale for accessing network increases, processing capacity is also needed
It improves.This can be by being distributed on multiple server cards in vRG and adding more services by the processing of data plane
