1. Routing (2) - Distance vector algorithm
2. Intra-AS routing in the Internet: OSPF
3. Routing among the ISPs: BGP
4. The SDN control plane
5. ICMP
6. SNMP

Terms of packet in different layers

• Application layer: message
• Transport layer: segment
• Network layer: datagram
• Link layer: frame

TCP three-way handshake

• A -> B: SYN (seq = x, ack = 0, L = 0)
• B -> A: SYN ACK (seq = y, ack = x+1, L = 0)
• A->B: ACK (seq=x+1,ack=y+1,L=0)

Flow Control vs. Congestion Control

• Host vs. Router

这周还是继续IP的学习

Lecture

记虽然笔记迟了，但是一定会补回来呀！
这周第一部分是TCP congestion control。我有空再写笔记，我们先进入第二环节。也就是网络层 Network layer.

网络层服务

• 在发送主机和接收主机对之间发送段（segment）
• 在发送端把段封装到数据报（datagram）中
• 在接收端，将段上交给传输层实体
• 网络层协议存在于每一个主机和路由器（全部都有）
• 路由器检查每一个经过他的IP数据报头部

This is the note of CAN201 Week5.
We will focus on Transport Layer.
Roadmap

1. Pipelined communication
2. TCP: connection-oriented transport
3. Principles of congestion control

This’s the note of introduction to networking Week4.
This week we will talk about the transport layer in networking system. 传输层

• Roadmap
