N-degree ROADM Architecture Comparison: Broadcast-and-Select vs Route-and-SelectADVA
The document compares the Broadcast-and-Select and Route-and-Select architectures for N-degree ROADM nodes in 120 Gb/s DP-QPSK transmission systems. It finds that Broadcast-and-Select has slightly lower penalties than Route-and-Select for N=4 and 9 due to less passband narrowing accumulation, but Route-and-Select has better isolation and fixed insertion loss. For larger N, Route-and-Select is preferable to mitigate higher potential crosstalk. Experimental results validated the predicted penalties from combined passband and isolation degradation analysis.

Hyper-V Replica is an asynchronous virtual machine replication technology included in Windows Server 2012. It is designed for business continuity and disaster recovery. It replicates individual or multiple virtual machines from a primary server to a replica server without requiring shared storage. Network adapter teaming enables multiple network adapters to be placed into a team interface, providing bandwidth aggregation and traffic failover to prevent connectivity loss if an adapter fails. Windows Server 2012 includes quality of service bandwidth management functionality that allows different types of network traffic to converge through a single adapter with predictable service levels.
VT-d and SR-IOV can improve IO virtualization performance. Microbenchmarks showed VT-d achieved near-native network and disk throughput. SR-IOV delivered 19Gbps network throughput across 30 VMs. Enterprise workloads saw VT-d match native database performance and enable higher VM consolidation. Analysis found VT-d introduced 5-12% overhead mainly from interrupt handling, which optimization can reduce.
This document discusses software-defined optical networks (SDON). It summarizes that SDON separates the control and data planes in networks, with a centralized controller taking command. The benefits include more efficient utilization of network resources through identifying packet flows and making smarter decisions. SDON also enables dynamic provisioning of network infrastructure to match daily traffic patterns. While direct control of optical networks offers most benefits, indirect control through an orchestration layer is easier to implement initially.

This thesis examines cross-layer interactions between middleware and routing protocols in mobile ad hoc networks (MANETs). The author developed CrossROAD, a middleware that optimizes the establishment and maintenance of a structured overlay network through interactions with the routing layer. An XL-plugin was also created to extend the proactive routing protocol UniKOLSR to support service discovery and allow information sharing between the middleware and routing layers. Experimental results showed CrossROAD performed well with low delays and supported mobility. Future work could explore using different routing protocols and evaluating applications' quality of service in larger, more mobile MANET environments.

Crossbow is a network virtualization and resource control architecture that aims to address problems with interrupt-driven packet delivery and lack of policy enforcement in traditional networking stacks. It classifies packets as low as possible and assigns unique resources like rings, interrupts, and threads per service, protocol, or virtual machine. This allows for policies to be enforced based on traffic type. The demo shows creating a virtual network interface for a virtual machine, adding a flow policy to limit SSH traffic to 50Mbps on that interface.

30. Applying the Tropos Powered
Solution – Self healing
Backhaul and Intranet Layer:
Provides a wired or wireless dedicated
backhaul connection between gateway mesh
routers and the agencies intranet (These can
be dynamically and incrementally added).
Wireless Mesh Layer:
As described above, the wireless mesh layer
provides multiple paths between routers and
gateways and ensures the best path is taken
(Additional free standing nodes can be added
to increase coverage).
Client Layer:
The link between clients and the mesh network
is provided via Wi-Fi connections depending on
the application (clients can operate anywhere
within the Tropos Mesh RF footprint).
