Network protocols are used to set network rules and principles in network connections and data transfer. Most of them are not needed though for most users and it aids primarily computer security since and intruder can exploit some of them through their corresponding applications and afterwards network speed when disabling them. The most common and present in a Windows 8 system protocols are:
Client for Microsoft Networks: The Client for Microsoft Networks component allows a computer to access resources on a Microsoft network.
For example, a protocol driver can call NdisInitializeEvent to create an event for synchronization purposes and NdisInitializeListHead to create a linked list. Protocol drivers that use the NDIS versions of such functions are more portable across Microsoft operating systems. However, protocol drivers can also call kernel-mode support routines. The protocol driver registered an entry point, if any, for this function in the NDISPROTOCOLDRIVERCHARACTERISTICS structure that it passed to the NdisRegisterProtocolDriver function. In response to a user request to uninstall a protocol driver, NDIS calls a protocol driver's ProtocolUninstall function. Microsoft Lldp Protocol Driver Purpose. The Link Layer Discovery Protocol (LLDP) is a vendor-neutral link layer protocol used by network devices for advertising their identity, capabilities, and neighbors on a local area network based on IEEE 802 technology, principally wired Ethernet.

QoS Packet Scheduler: The Quality of Service Packet Scheduler is a Windows platform component that is enabled by default and is designed to control the IP traffic for various network services, as a method of network bandwidth management that can monitor the importance of data packets and based on the priority of the packet.
File and Printer Sharing for Microsoft Networks: The File and Printer Sharing for Microsoft Networks component allows other computers on a network to access resources on your computer by using a Microsoft network. This component is installed and enabled by default for all VPN connections. However, this component needs to be enabled for PPPoE and dial-up connections. It is enabled per connection and is necessary to share local folders.
Microsoft Network Adapter Multiplexor Protocol: The Microsoft Network Adapter Multiplexor Protocol service is a kernel mode driver. If the Microsoft Network Adapter Multiplexor Protocol fails to start, the error is logged. Windows 8 startup proceeds, but a message box is displayed informing you that the NdisImPlatform service has failed to start. This protocol is used
for Netword Interface Card bonding, which is the combining of two ethernet cards to appear as one physical device in order to increase the available bandwidth.
Microsoft LLDP Protocol Driver: The Link Layer Discovery Protocol (LLDP) is a link layer protocol used by network devices for advertising their identity, capabilities and neighbors on an IEEE 802 local area network.
Link-Layer Topology Discovery: The Link-Layer Topology Discovery service is a kernel mode driver. If the Link-Layer Topology Discovery Mapper I/O Driver fails to start, the error is logged. Windows 8 startup proceeds, but a message box is displayed informing you that the lltdio service has failed to start. The drivers is responsible for displaying and representing computers and devices on a map. It consists of two components, the Mapper I/O Driver and the Responder which work together for the service to exist.
Internet Protocol version 6 (TCP/IPv6): Internet Protocol v6 (IPv6) is the latest revision of the Internet Protocol (IP), the communications protocol that routes traffic across the internet and is intended to replace IPv4. IPv6 is designed to solve many of the problems of IPv4, including mobility, auto-configuration, and overall extensibility. IPv6 expands the address space on the Internet and supports a nearly unlimited number of devices that can be directly connected to the Internet.
Internet Protocol Version 4 (TCP/IPv4): Internet Protocol v4 (IPv4) is the fourth revision of the Internet Protocol and a vastly used protocol in data communication over different kinds of networks. IPv4 is a protocol used in packet-switched layer networks, such as Ethernet. It provides the logical connection between network devices by providing identification for each device.
Most users don’t need most of these protocols except of course for the TCP/IPv4 protocol which is the fundamental protocol for an internet connection. For instance if you don’t have a server and don’t need file and printer sharing you can disable “File and Printer Sharing over Microsoft Networks” which will increase your security dramatically. If you don’t want to access resources in a Microsoft network you can disable the corresponding protocol. It is nearly certain that your computer does not use the TCP/IPv6 so you can disable that protocol as well. In the same manner if you ‘re not interested to see your connected devices as a map you can disable the Link-Layer Topology Discovery components as well. You can also increase your network security by disabling the Microsoft Network Adapter Multiplexor Protocol and the LLDP protocol since the former can cause port security issues when the MAC address has been granted the right for a connection and one of the NICs fail and the other one doesn’t and the later because it provides the ability for ethernet cards to be discovered over the network which in some cases can cause a security issue. Finally, QoS Packet Scheduler is not supported in most ethernet cards and one might see a slight network speed increase by disabling it.

The LLTD protocol enables applications to quickly discover devices at the data-link layer, and it enables a central, graphical view of everything that is connected to the network. Any device that implements LLTD appears on the Network Map with a rich icon that represents the device, allowing users one-click access to the device’s Web user interface (UI).
LLTD provides the added benefit of enabling quality media streaming experiences, even on networks with limited bandwidth. Devices that provide audio or video playback or that are bandwidth sensitive can implement the QoS Extension portions of the protocol to ensure that they receive prioritized streams and that changes in available bandwidth have little or no impact on the user experience.
Implement LLTD with a custom icon to ensure that your product’s industrial design or form factor is graphically depicted.

Network Topology and QoS Extensions: LLTD
The specification for Link Layer Topology Discovery describes how the LLTD protocol operates over wired (802.3 Ethernet) and wireless (802.11) media. As the protocol name suggests, LLTD enables device discovery via the data-link layer (Layer 2) and determines the topology of a network. In addition, LLTD provides QoS Extensions that enable stream prioritization and quality media streaming experiences even on networks with limited and changing bandwidth. Applications can dynamically adapt to changing network characteristics if devices support LLTD QoS Extensions.
Exploring the Network: Link Layer Topology Discovery
LLTD is a key Windows Rally technology. In every version of Windows Vista, LLTD is on and enabled by default. Devices can also implement LLTD—and those that do so can report rich configuration information about themselves that appears in the various network map views available in Windows Vista, regardless of any IP configuration issues on the network. When LLTD is invoked, it provides metadata about the device that contains static or state information, such as the MAC address, IPv4/IPv6 address, signal strength, and so on, as well as a scaleable icon that represents the industrial design or form factor of the device.
In addition, the Windows Vista Network Map uses LLTD to determine connectivity information and media type (wired or wireless), so that the map is topologically accurate. The ability to know network topology is important for diagnosing and solving networking problems, and it is especially important for streaming content over a wireless connection. Providing a centralized Network Map ensures that a user-friendly view is easily available to show the overall network state and device health, to either the end user or a support assistant. LLTD is meaningful for device vendors who:
- Want to reduce support costs and product returns due to setup problems.
- Would like their products’ industrial design or form factor to appear to users in Windows Vista.
LLTD enables easy, one-click access to the device’s setup and management Web UI. The Windows Vista Network Map exposes the device UI as a right-click option, thereby providing easy access to the device, regardless of whether the customer installed a custom setup utility.

QoS Extensions: Prioritizing Audio/Video Streams to Devices
QoS refers to the mechanisms used to provide a desired level of network service to an application on IP-based networks. On a home network, A/V streaming traffic competes with other data and best-effort traffic. QoS support for A/V on home IP networks is advanced through new support in Windows Vista: qWAVE and QoS Extensions to LLTD.
qWAVE provides an API that allows applications to dynamically adapt to changing network conditions in real time. This technology enables A/V applications to provide a quality user experience, especially on wireless home networks. qWAVE provides new features that focus on streaming multimedia and real-time content over variable bandwidth networks, including:
Lldp Protocol Cisco
- Auto-discovery of end-to-end QOS compatibility
- End-to-end bandwidth estimation of maximum link capacity (bottleneck bandwidth) and real-time available bandwidth
- Intelligent packet prioritization
- Congestion notification
- Flow shaping (rate throttling)
- Distributed admission control to enable multisource stream coexistence
qWAVE-enabled applications work together with devices that implement the LLTD QoS Extensions to greatly improve an end user’s experience of streaming video by safely and intelligently prioritizing traffic and reducing the impact of network-related transient issues.
