Using eCDNs in mDNS enabled networks has been a big challenge for a long time. In February 2021, StriveCast developed a solution that solved this problem. By placing the StriveCast Peering Manager in the corporate network, all clients within a subnet could establish peer-to-peer connections and share data with each other. Now we have extended this feature: StriveCast is the only provider that has succeeded subnet matching in mDNS-enabled networks without requiring complex software installations on all end devices.
How does mDNS affect the success of a P2P eCDN?
The first P2P based eCDN that solved the mDNS problem smartly
In February 2021, StriveCast was the first eCDN provider to present a solution for peer-to-peer-based eCDN in networks using mDNS without installing additional software on each end device. StriveCast was now able to solve the problem of IP address obfuscation by mDNS. This is done by placing the StriveCast Peering Manager within the internal network. The local IP addresses can be identified by having all end devices that access a stream automatically connect to the StriveCast Peering Manager. While these cannot be used directly to establish peering connections due to the mDNS feature, they do provide information about which devices are in each subnet and therefore suitable for peering. Accordingly, a peer-to-peer network can be established within subnets, and bandwidth can be reduced. But until now, the full potential of a P2P-based eCDN couldn’t be fully exploited because devices from different subnets weren’t able to connect to each other.
Subnet matching with mDNS
Many companies have a complex subnet structure within their corporate networks. The number of devices that can connect to each other for peering used to depend mainly on the number of users located within the subnet. The fewer devices within each subnet, the more limited was the eCDN’s efficiency regarding traffic savings. StriveCast now solves this problem as the only eCDN provider on the market: The StriveCast Peering Manager is now able to form peer-to-peer connections beyond the boundaries of a subnet and thus connects significantly more end devices. This leads to saving even more bandwidth and reducing traffic, so a network overload can be efficiently prohibited.
Success Story: Subnet Matching with Amprion
During the Covid-19 pandemic, StriveCast and Amprion, one of four transmission system operators in Germany, realized a digital town hall meeting for over 1,000 employees. This project posed several challenges to the IT team: while about 50% of the attendees participated from their home offices, the remaining employees accessed the stream from the corporate network. StriveCast was able to help avoid network congestion and achieve bandwidth savings of up to 87%. A key reason for this success was the establishment of peer-to-peer connections beyond the boundaries of individual subnets.
