What is a Protocol?
| OSI Layer | Name | Common Protocols |
| 4 | Transport | TCP | SPX |
| 3 | Network | IP | IPX |
| 2 | Data Link | Ethernet |
| 1 | Physical |

Keeping this in view, what OSI layer is HTTP?
Some said HTTP is in the session layer in the OSI model. But in Tanenbaum's Computer Network, HTTP is said to be in the application layer in the OSI model.
Subsequently, question is, what layer is TCP and UDP? In terms of the OSI model, IP is a network-layer protocol. It provides a datagram service between applications, supporting both TCP and UDP.
Also know, which layer is OSPF?
Wikipedia says RIP operates on the application layer and OSPF operates on the internet layer of the internet protocol suite.
What are the layer 2 protocols?
Ethernet, Token Ring, and Frame Relay are all examples of Data Link layer or Layer 2 protocols. Traditional Ethernet switches operate at the Data Link layer and are con- cerned with forwarding packets based on the Layer 2 addressing scheme.

What layer is ARP?
ARP is layer 2. The reason being is that a broadcast is sent on layer 2 (data link layer) and ARP will normally not traverse to layer 3 (network layer). However it can provide extra features to the layer 3 protocol. The truth is that not all protocols fit the OSI model exactly, because after all it's just a model.What OSI layer is WIFI?
A wireless engineer lives in layers 1 - 2. Although we are expected and should know all layers! As you know, when wireless doesn't work, its a wireless problem regardless if it's routing or something else! The 802.11 protocol operates in two very specific layers of the OSI model; LAYER 1 and LAYER 2.What layer is pop?

Is OSPF TCP or UDP?
Open Shortest Path First (OSPF) is a link-state routing protocol. OSPF does not use a TCP/IP transport protocol (UDP, TCP), but is encapsulated directly in IP datagrams with protocol number 89.What OSI layer is BGP?
BGP is on top of TCP, so it would be Internet layer 4, OSI layer 7. Usually external BGP is done only between 2 directly connected peers, enforced by setting TTL flag on IP header, which is located at layer 3.Why is OSPF backbone?
OSPF requires all areas to attach directly to the backbone so it limits the topology to a simple hub and spoke topology. This eliminates redundant paths and prevents it from being subjected to 'count to infinity' problems.Why RIP uses UDP?
Explanation: RIP uses distance vector routing (DVR) protocol which employ the hop count as a routing metric. Also, RIP uses the UDP as its transport protocol with port no 520. OSPF encapsulates its data directly into IP Packets and does not use either TCP or UDP.Does Eigrp use TCP or UDP?
EIGRP does not operate using the Transmission Control Protocol (TCP) or the User Datagram Protocol (UDP). This means that EIGRP does not use a port number to identify traffic. EIGRP uses 224.0. 0.10 as its multicast address and protocol number 88.Who created OSPF?
Internet Engineering Task Force (IETF
Is OSPF a layer 3 protocol?
At Layer 3, routers will use dynamic routing protocols (generally Open Shortest Path First or OSPF and BGP in most enterprises) to present a robust network that handles site-to-site link failures and minimizes the burden of IP management.Where is OSPF used?
The OSPF (Open Shortest Path First) protocol is one of a family of IP Routing protocols, and is an Interior Gateway Protocol (IGP) for the Internet, used to distribute IP routing information throughout a single Autonomous System (AS) in an IP network.Is it Layer 2 or 3?
While OSPF was natively built to route IP and is itself a Layer 3 protocol that runs on top of IP, IS-IS is an OSI Layer 2 protocol. It is at the same layer as Connectionless Network Protocol (CLNP). Both OSPF and IS-IS routers build a topological representation of the network.Is IP a TCP or UDP?
Both TCP and UDP are protocols used for sending bits of data — known as packets — over the Internet. They both build on top of the Internet protocol. In other words, whether you are sending a packet via TCP or UDP, that packet is sent to an IP address. The widely used term “TCP/IP” refers to TCP over IP.Is TCP faster than UDP?
15 Answers. UDP is faster than TCP, and the simple reason is because its nonexistent acknowledge packet (ACK) that permits a continuous packet stream, instead of TCP that acknowledges a set of packets, calculated by using the TCP window size and round-trip time (RTT).
