tapping the network layer headers of packets transmitted by its neighbors will potentially learn significantly more topology information if the network employs a source routing protocol than it would if a next-hop routing protocol was employed. Since such passively acquired topology data can be used in the route discovery process,

Abstract. At present, link layer topology discovery methodologies rely on protocols that are not universally available, such as SNMP. Such methodologies can only be applied to a subset of all possible networks. Our goal is to work towards a generic link layer topology discovery method that does not rely on SNMP.

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. Network layer: The functions of the network layer are to 1) provide (IP) addresses to end hosts, and 2) set up routes between sources and destinations, proactively (routes ready-to-use) or reactively (routes on-demand). To set up a route, we need route discovery; to make routes ready to use, we need route maintenance. 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.When Data Link Layer has a Layer 3 packet to transmit, it starts a new session and sends the packet right away using a DATA packet. The algorithm waits for an acknowledgment (ACK) packet. If an ACK is not received before the timeout period, it backs off a random amount of time and sends the DATA packet again. 2. It is unclear whether internet layer addresses would be carried in LLDP. If so, it would constitute a layering violation. 3. The security considerations in G.phnt were lacking. 4. It is unclear whether G.phnt can be extended in future to allow the protocol to act as a topology discovery mechanism across multiple links. As the current G.phnt ...
2 days ago · Their algorithm can handle both Layer-2 switches with VLAN and Layer-3 switches. Analogously, Wang et al. introduced a network topology discovery algorithm based on SNMP, which can discover the target topology completely and accurately through combining the topology discovery of the network layer and link layer. They identify that there are ...

The Link Layer Topology Discovery protocol is a newly developed protocol designed by Microsoft for discovering hosts on the local network. LLTD is a core component in Microsoft’s network diagnostic strategy. By providing high-quality topology information to end users, Microsoft hopes to make it easier for users to manage their home networks. Link Layer Topology Discovery (LLTD) is a proprietary Link Layer protocol for network topology discovery and quality of service diagnostics. Microsoft developed it as part of the Windows Rally set of technologies. The LLTD protocol operates over both wired (IEEE 802.3 Ethernet or power lines [1]) as well as wireless (IEEE 802.11) networks.

An application hands off a chunk of data to the TCP library, which in turn makes calls to the IP library, which in turn calls the LAN layer for actual delivery. An application does not interact directly with the IP and LAN layers at all. The LAN layer is in charge of actual delivery of packets, using LAN-layer-supplied addresses.
