A network of networks (internetwork)
Clients and servers
Individual computers that initiate requests or provide services - Computers - Servers - Printers - etc.
Hosts (clients and servers)
Switches and router
A specialized node that connects between networks. Forwards packets, implements security (firewall and NAT)
Two or more nodes connected by a link
Provide connectivity
A set of rules for how devices communicate and how data is transmitted across a network
- Hosts and applications - Clients and servers
mesh of interconnected routers
1. Transmission rate 2. Shared or dedicated access among users
You usually need to download more than you need to upload
- Wired Access Network - Wireless Access Network (WAN) - Wireless Local Access Network (WLAN) - Wide-Area Cellular Access Network
Wireless Access Network that connects end systems to router.
Wireless Local Area Network. Typically within or around a building
Network Address Translation. Hides all devices in a home network behind a single public IP address.
The transmission rate of a communication link
End-end resources allocated to/reserved for "call" between source and destination. Divides link bandwidth into pieces (FDM and TDM)
Frequency Division Multiplexing. Partitions a resource in frequency.
Time Division Multiplexing. Partition a resource in time.
Data sent through network in discrete chunks (packets). Allows more users to use a network.
Packets are multiplexed based on statistical behavior of the traffic. - Packets are distributed in the network, and are then assembled at the end user.
entire packet must arrive at router before it can be transmitted on next link
1. Processing 2. Queueing 3. Transmission 4. Propagation
Packets are arriving faster than they are being transmitted (queueing for too long)
Bursty data
Reliable data transfer (Congestion and resource contention, packet delay/loss)
Transfer Size / Time to Transfer The bandwidth perceived by the user
Internet Exchange Point. Connects the internet to multiple ISPs around the world. Actual physical buildings.
A link that connects ISPs without going through an IXP directly
Internet Service Provider. Provides and manages a network
- Residential access nets - Institutional access networks - Mobile access networks
1. Tier 1 ISPs and CPNs 2. IXPs 3. Regional ISPs 4. Access ISP
Content Provider Network. Private networks that connect their data centers to the internet, bypassing ISPs
- Google - Facebook
Supports network applications
Process-process data transfer
Routing of datagrams from source to destination
Data transfer between enighboring network elements
bits "on the wire"
