Network topology is the physical design of a LAN which resolves the conflict that occurs between computers on the network attempting to transmit at the same time. Whereas protocols are the standards used by networks to permit communication between network-connected devices. -s74
Group of devices connected together forms a Network & structure (design) in which they interconnect is called Topology.
Topology is the actual layout of the network, for instance, where the routers and other devices are located. That would be the networks topology.
Network architecture refers to the design and structure of a network, including components, protocols, and technologies used for communication. Network topology, on the other hand, refers to the physical or logical layout of devices and how they are connected in a network, such as bus, star, ring, or mesh. In essence, network architecture defines how components work together, while network topology defines how components are arranged.
Physical topology are says how the wire are interconnected, while Logical topology is how the network behaves and interoperates.Sk wasim ul HaqueKharagpur, Madpur

A network layer refers to one of the actual 7 layers. The network layer protocol is actually the system it uses, possibly the order that the layers are done by?
protocol, token, proxy or packet
Also called signal topology. Every LAN has a topology, or the way that the devices on a network are arranged and how they communicate with each other. The way that the workstations are connected to the network through the actual cables that transmit data -- the physical structure of the network -- is called the physical topology. The logical topology, in contrast, is the way that the signals act on the network media, or the way that the data passes through the network from one device to the next without regard to the physical interconnection of the devices. Logical topologies are bound to the network protocols that direct how the data moves across a network. The Ethernet protocol is a common logical bus topology protocol. LocalTalk is a common logical bus or star topology protocol. IBM's Token Ring is a common logical ring topology protocol. A network's logical topology is not necessarily the same as its physical topology. For example, twisted pair Ethernet is a logical bus topology in a physical star topology layout. While IBM's Token Ring is a logical ring topology, it is physically set up in a star topology.
Topology
TCP is the protocol of network layer, It is connection oriented protocol. UDP is the protocol of network layer, It is connection less protocol.
For WANs depending on the protocol the packets can be very different. For LANs, the ring topology insists on special packets proceeded by a "token".
