Therefore, optical wireless
mesh is a very scalable technology.
Quality of Service At the physical level, the quality of service (QoS) offered by optical
mesh can come close to the quality of service offered by any other network technology.
The optical wireless links in a mesh network provide reliability comparable to that of
252 Chapter 9
fiber-optic cable, ensuring end-to-end delivery of data traffic. Optical wireless networks
also offer very low latency and jitter, also comparable to that of fiber-optic networks.
And in the unlikely event of link failure, a mesh network??™s resiliency allows the traffic
path to be reestablished, the expediency of which is comparable to that of any other
wired network.
At the network level, each node of a mesh network can offer the full suite of QoS
capabilities, making wireless optical mesh like virtually any other network. Each node
can be a fully MEF-compliant Layer 2 switch, offering MEF-compliant QoS and SLA.
Each node can even be an MPLS switch, enabling the mesh network to offer the type
of traffic engineering required to offer Carrier Ethernet and matched only by wired
networks.
Support for TDM Services An optical wireless mesh network is no different from any
other wired technology in its ability to offer Carrier Ethernet services.
