There are several network layer protocols which are listed below. However, here we will discuss the first two protocols which are commonly known as IP address of the device or computer:
Network Layer Protocols list
- IPv4, Internet Protocol version 4
- IPv6, Internet Protocol version 6
- DDP, Datagram Delivery Protocol
- DVMRP, Distance Vector Multicast Routing Protocol
- ICMP, Internet Control Message Protocol
- IGMP, Internet Group Management Protocol
- IPsec, Internet Protocol Security
- IPX, Internetwork Packet Exchange
- PIM-DM, Protocol Independent Multicast Dense Mode
- PIM-SM, Protocol Independent Multicast-Sparse Mode
- RIP, Routing Information Protocol
- RSMLT Routed-SMLT
Characteristics of IP
IP was planned as a protocol with low overhead. It provides only the functions that are required to deliver a packet from a source to a destination over an interconnected network. The protocol doesn’t track and manage the flow of packets. The basic characteristics of IP are following:
There is no connection established with the destination before sending data packets.
IP is inherently unreliable because packet delivery is not guaranteed.
The operation is dependent on the medium (i.e., copper, fiber optic, or wireless) carrying the data.
