In 2020,multimedia services,especially video streaming,have become an important part of
Internet traffic, as well as increasing video service providers, such as Netflix, Amazon, YouTube,
etc, with the explosive growth of multimedia content and users, network resources such as
bandwidth will become increasingly scarce. In users′ usage habits, there will be a large number of
users watching the same video at a certain time, such as sports live events. In the traditional
unicast network video distribution service, there will be too many duplicate content on the link,
which makes the originally strained bandwidth resources worse. Multicast is a method of
communication between one sender and multiple receivers, which can solve this problem well.
However, due to the decentralized design of traditional IP multicast, it is difficult to construct a
multicast distribution tree with full consideration of network bandwidth resources. In addition, in
the face of network bandwidth bottleneck, VSP also uses HTTP adaptive streaming to
dynamically adjust the bit rate of video received by users according to the link bandwidth
condition from server to client, so as to avoid stalling events. However, this is based on the use of
unicast transmission, which is used in combination with H.264 AVC. If H.264 AVC video coding
format is directly used in multicast, it will also cause waste of bandwidth resources.
In the face of the existing IP multicast difficult to construct the multicast distribution tree
according to the whole domain bandwidth of the network topology and how to use adaptive
streaming in the multicast. SDN based multicast video content distribution can be achieved by
using the centralized control of SDN network, global view of network and H.264 SVC video
coding format. In this paper, a new entry configuration method called VLAN based multicast is
proposed. Firstly, a multicast distribution tree is constructed based on prim algorithm to improve
the overall link bandwidth utilization rate to improve the bit rate of video received by users,
Secondly, configure different VLANs for each segment (the path from sender Node to Branch
Node, Branch Node to next level Branch Node, Branch Node to each receiver Node is called
segment), the bit rate of the video received by the user can be adjusted at a lower cost, realize
adaptive streaming, and save TCAM space of intermediate nodes. |
