Windows 8 : Installing Networking Components

Automatic Black Hole Router Detection

Prevents TCP connections from terminating due to intermediate routers silently discarding large TCP segments, retransmissions, or error messages.

Automatic Dead Gateway Retry

Ensures that an unreachable gateway is checked periodically to determine whether it has become available.

Compound TCP

Optimizes TCP transfers for the sending host by increasing the amount of data sent in a connection while ensuring that other TCP connections are not affected.

Extended Selective Acknowledgments

Extends the way Selective Acknowledgments (SACKs) are used, enabling a receiver to indicate up to four noncontiguous blocks of received data and to acknowledge duplicate packets. This helps the receiver determine when it has retransmitted a segment unnecessarily and adjust its behavior to prevent future retransmissions.

Modified Fast Recovery Algorithm

Provides faster throughput by altering the way that a sender can increase the sending rate if multiple segments in a window of data are lost and the sender receives an acknowledgment stating that only part of the data has been successfully received.

Neighbor Unreachability Detection for IPv4

Determines when neighboring nodes and routers are no longer reachable and reports the condition.

Network Diagnostics Framework

Provides an extensible framework that helps users recover from and troubleshoot problems with network connections.

Receive Window Auto Tuning

Optimizes TCP transfers for the host receiving data by automatically managing the size of the memory buffer (the receive window) to use for storing incoming data based on the current network conditions.

Routing Compartments

Prevents unwanted forwarding of traffic between interfaces by associating an interface or a set of interfaces with a logon session that has its own routing tables.

SACK-Based Loss Recovery

Makes it possible to use SACK information to perform loss recovery when duplicate acknowledgments have been received and to recover more quickly when multiple segments are not received at the destination.

Spurious Retransmission Timeout Detection

Provides correction for sudden, temporary increases in retransmission timeouts and prevents unnecessary retransmission of segments.

TCP Extended Statistics

Helps determine whether a performance bottleneck for a connection is the sending application, the receiving application, or the network.

Windows Filtering Platform

Provides application programming interfaces (APIs) for extending the TCP/IP filtering architecture so that it can support additional features.

DHCPv6-Capable DHCP Client

Extends the DHCP client to support IPv6, and allows stateful address autoconfiguration with a DHCPv6 server.

IP Security

Allows use of Internet Key Exchange (IKE) and data encryption for IPv6.

IPv6 over Point-to-Point Protocol (PPPv6)

Allows native IPv6 traffic to be sent over PPP-based connections, which in turn allows remote access clients to connect with an IPv6-based Internet service provider (ISP) through dial-up or PPP over Ethernet (PPPoE)–based connections.

Link-Local Multicast Name Resolution (LLMNR)

Allows IPv6 hosts on a single subnet without a DNS server to resolve each other’s names.

Multicast Listener Discovery version 2 (MLDv2)

Provides support for source-specific multicast traffic and is equivalent to Internet Group Management Protocol version 3 (IGMPv3) for IPv4.

Random Interface IDs

Prevents scanning of IPv6 addresses based on the known company IDs of network adapter manufacturers. By default, Windows 8 generates random interface IDs for nontemporary, autoconfigured IPv6 addresses, including public and link-local addresses.

Symmetric Network Address Translators

Maps the internal (private) address and port number to different external (public) addresses and ports, depending on the external destination address.
