“…Since TCP is optimized for the general use, it exhibits limitations in scenarios like bulk transfer, multicast, concurrent systems, computational grids, fast networks, etc. [36], [16], [13], [25], [24], [21], [17]. This motivated the design of reliable transport-level alternatives on top of UDP.…”

TCP is typically the default transport protocol of choice for its supposed reliability, even for message-oriented middleware (e.g., ZeroMQ) or inter-actor communication (e.g., distributed Erlang). However, under network issues, TCP connections can fail, which requires ensuring both at-least-once and at-most-one delivery at the upper middleware layer. Moreover, the use of TCP at scale, in highly concurrent systems, can lead to drastic performance loss due to the need for TCP connection multiplexing and the resulting head-of-line blocking. This paper introduces Exon, an oblivious exactly-once messaging protocol, and a corresponding lightweight library implementation. Exon uses a novel strategy of a per-message four-way protocol to ensure oblivious exactly-once messaging, with on-demand protocol-level "soft half-connections" that are established when needed and safely discarded. This achieves correctness, obliviousness, and performance, through merging and pipelining basic protocol messages. The empirical evaluation of Exon demonstrates significant improvements in throughput and latency under packet loss, while maintaining a negligible overhead over TCP in healthy networks.

“…Erlang is a general-purpose functional language initially developed by Ericsson to build high-performance telecom switch systems. These systems are expected to scale horizontally, handle a heavy load with very low latency, and run practically forever without service interruption [2]. These specific requirements guided the design of the language: a) Firstclass processes with strong isolation; b) Integrated support for transparent distribution; c) High-level distributed coordination mechanisms; d) Sophisticated fault tolerance abstractions; e) Automatic memory management; f) Soft real-time support; and g) Hot-loading software updates.…”

Scalability and resiliency are two significant requirements for upcoming beyond 5G networks. As network resource usage is expected to increase, scalability of the control plane handling the required amount of network resources is also necessary. Moreover, resiliency of cloudified control plane software mechanisms is also a requirement. This demonstration presents an Erlang-based Path Computation Element (PCE) able to perform traffic engineering for Segment Routing. Specific scalability and resiliency properties are provided in order to support transport connectivity in beyond 5G networks.
