TCP/IP Protocol Suite
The TCP/IP protocol suite consists of many protocols that operate at one of 4 layers. The protocol suite is named after two of the most common protocols – TCP (Transmission Control Protocol) and IP (Internet Protocol).
Layer 3 vs. Layer 4
In Layer 3 mode, the device tracks sessions based on source and destination IP address and port. In Layer 4 mode, the device tracks IP addresses in addition to source and destination ports. This allows the device to make a granular load balancing decision.
Internet Protocol Stack Layers
There are five layers in the Internet Protocol stack.
Riguardo a questo, what is stack example? A stack is an abstract data type that holds an ordered, linear sequence of items. In contrast to a queue, a stack is a Last In, First Out (LIFO) structure. A real-life example is a stack of plates: you can only take a plate from the top of the stack, and you can only add a plate to the top of the stack.
La gente chiede anche:, why protocol stack is required? The protocol stack is used to allow the combination of different protocols that each set the boundaries for a number of network activities. These functions are all separated into separate ‘layers’ of data that all require a protocol to be transferred. What does a layer 3 address look like? The layer 3 address is a logical address. It will pertain to a single protocol (such as IP, IPX, or Appletalk). A computer can have any number of layer 3 addresses but it will only have 1 layer 2 address per LAN interface. At layer 3, the data is addressed to the host that the data is destined for.
