Chapter 3 Single Path TCP Figure 3.1: TCP protocol is used by applications to communicate with each other over the internet. The TCP protocol is a connection oriented protocol.TCP provides reliable transmission of data in IP environment. .Services TCP pro- vides are stream data transfer,reliability,flow control and multiplexing .With stream data transfer,TCP delivers an unstructured stream of bytes identified 4 by sequence numbers.This service benefits applications because they do not have to chop data into blocks before handing it over to TCP.fig 3.1 shows how a single path TCP connection is established. 3.0.1 Disadvantages of A Single Path TCP 1)Offers less Reliability . 2)Less Load Balancing Capacity 3)Less Fault Tolerant . 3.0.2 Need …show more content…

Even congestion Control is also dependent on the Design .Using an effecient design is the most basic way of congestion control.Better the design lesser will be the chances for congestion. 6.1 Design Goals for Multipath TCP The various Design goals for multipath TCP are listed below Each one will be explained in detail . 1)MultiPath TCP should be fair to regular TCP 2)Be fair to regular TCP 3)Use Efficient Paths 4)Adapt quickly when congestion occurs 5)A Multipath TCP user should get at least as much throughput as a single- path TCP would on the best of the available paths. 6)A Multipath TCP flow should take no more capacity on any link than a single-path TCP would 12 6.1.1 Multipath TCP should be fair to regular TCP Figure 6.2: Design Goal 1 As the design goal suggests that the multipath TCP should be fair to regular TCP which means that it multpath TCP should not take anything on any link more than the capacity of the regular TCP .If it doesnt do so then it is unfair to regular TCP
