Network Layer: transport layer relies on the network layer (3) to provide host-to-host communication. There’s a piece of network layer in every host and router in the network. Transport segment from sending to receiving host. On sending, Host 1 encapsulates segments into datagrams. On receiving, Host 2 delivers datagrams to transport layer. Protocols in every host, router. Router examines header fields in all IP datagrams passing through it. Moves packets from sending to receiving hosts. Routers:

1 Cisco Notları OSI Referans Modeli Bilgisayar ağları kullanılmaya başlandığı ilk zamanlarda sadece aynı üreticinin ürettiği cihazlar birbirleriyle iletişim kurabiliyordu. Bu da şirketleri tüm cihazlarını sadece bir üreticiden almalarını zorunlu kılıyordu. 1970’lerin sonlarına doğru ISO (International Organization for Standardization) tarafında, OSI (Open System Interconnection) modeli tanımlanarak bu kısıtlamanın önüne geçildi. Böylece farklı üreticilerden alınan cihazlar aynı ağ ortamında birbirleriyle

The Network layer, or OSI Layer 3, provides services to exchange the individual pieces of data over the network between identified end devices. To accomplish this end-to-end transport, Layer 3 uses four basic processes: Addressing Encapsulation Routing Decapsulation Addressing= First, the Network layer must provide a mechanism for addressing these end devices. If individual pieces of data are to be directed to an end device, that device must have a unique address. In an IPv4 network, when
