With the development of network infrastructure, the network stack needs to be re-invented to meet the highly diversified and ultimate QoS/SLA requirements from the next generation Internet applications. There are some challenges as the following: - Legacy TCP is best effort based, no performance guarantee. - One-size-fits-all protocol or algorithm becomes less feasible. - Complicated and heterogeneous network environments makes common optimization less possible. - Growing concern on security on any given protocol.
Huawei designed a new open source protocol development kit - DMM(Dual-domain,Multi-protocol, Multi-instance), which provides an extendable transport protocol framework and runtime library, accelerate current transportation protocol performance and new protocol adaption. Huawei wants to share DMM with developers, build up an friendly ecosystem for network stack together.
