RSVP is designed to clear a path for audio and video traffic to reduce packet delay and loss. This flow-based communication protocol, which signals a switch or router to reserve bandwidth for a real-time transmission, such as a VoIP (voice over IP) call, allows a node to specify an end-to-end delay, such as 100 ms.
RSVP does not scale well, however, as every device along the path from packet origin to destination needs to maintain the state of the connection. Therefore, small to midsize enterprises can benefit from RSVP; large enterprises must discriminate services without maintaining a per-flow state at every switch. QoS strategies such MPLS and DiffServ will likely be more suitable.
Subsea cable alternatives can provide a level of comfort for those concerned about disruptions. Realistically, they will continue to play a small, but critical role in the short term.
Maintaining existing network infrastructures often incurs huge technical debt before newer technologies are adopted over time.
Amid ongoing regional uncertainties, telecom infrastructure in the Middle East has expand to include terrestrial low-latency network infrastructure, which offers resilience and agility in navigating political complexities without relying solely on undersea networks.
