MOAC 70-741 Lesson 12 Implementing High-Performance Network Solutions
Quality of Service (QoS)
A collection of technology that ensures high-quality performance for critical applications. It measures network bandwidth, detects changing network connections, such as congestion or availability of bandwidth, and then prioritizes or throttles network traffic.
Data Center Bridging (DCB)
A suite of Institute of Electrical and Electronics Engineers (IEEE) standards that supports converged networks so network traffic can get sufficient bandwidth allocation, while maintaining reliability.
Switch Independent Mode
All of the network adapters are connected to different switches, providing alternative routes through the network. Static teaming and LACP are switch dependent modes.
Switch Dependent Mode
All of the network adapters are connected to the same switch, providing a single interface with their combined bandwidth.
Single-Root I/O Virtualization (SR-IOV)
Allows a device, such as a network adapter, to distribute access to its resources among PCI Express hardware functions. You can configure a maximum number of offloaded security associations from 1 to 4,096. This feature is supported only on Hyper-V-specific network adapters.
Network Direct (Remote Direct Memory Access [RDMA])
Allows the network adapter to transfer data directly to or from the application memory, without any work being done by the processor, which allows high-throughput, low-latency networking.
Switch Embedded Teaming (SET)
Allows you to use a Hyper-V virtual switch to team up to eight physical Ethernet adapters located on the same Hyper-V host into one or more software-based virtual network adapters. The virtual network adapters provide fast performance and fault tolerance in the event of a network adapter failure.
NIC Teaming
Also called bonding, balancing, and aggregation, NIC Teaming is a Windows feature that enables administrators to join multiple network adapters into a single entity, for performance enhancement or fault-tolerance purposes.
Server Message Block (SMB)
Also known as Common Internet File System (CIFS), SMB is a client/server file-sharing protocol that was created in 1984 by Microsoft.
Common Internet File System (CIFS)
Also known as Server Message Block (SMB), CIFS is a client/server file-sharing protocol that was created in 1984 by Microsoft.
dynamic VMQ
Dynamically distributes incoming network traffic processing to physical host CPU cores based on processor usage and network load.
IPsec task offloading
Enables IPsec task offloading at the machine level, reducing the demands on the virtual machine's CPU by using a dedicated processor on the physical network adaptor. This feature is only supported on Hyper-V-specific network adapters.
SMB Direct
Enables direct memory-to-memory data transfers between servers, with minimal CPU utilization and low latency, using standard RDMA-capable network adapters (iWARP, InfiniBand, and RoCE). It also minimizes the processor utilization when performing large file I/O operations. SMB Direct functionality requires that the SMB client and SMB server support SMB 3.0.
Receive Side Scaling (RSS)
Enables the distribution of incoming network processing across multiple processor cores in multi-core computers, which can help increase performance.
Server Message Block (SMB) 3.0
Introduced with Windows 8 and Windows Server 2012, SMB 3.0 brings significant changes to add functionality and improve performance, particularly in virtualized data centers.
Packet Direct
Replaces the Network Driver Interface Specification (NDIS), which has been the standard network driver interface for the last 20 years, and was not designed for 100-GB network speeds. Packet Direct enables compliant applications to tell the network what they need, thereby increasing the efficiency of the network stack.
converged network
Shares a single network infrastructure that handles storage, data, voice, video, cluster, and management traffic.
Virtual Machine Multi-Queues (VMMQs)
Traffic is spread across multiple queues per virtual machine.
Virtual Machine Queue (VMQ)
Uses hardware packet filtering to deliver data directly to virtual machines from an external network, reducing the overhead of routing packets from the management operating system to the virtual machine. Only Hyper-V-specific network adapters support this feature.
