-Lecture Topic: Delay and Internet Layering
-
-# Single Packet over Same Rate Links
-If each node has the same rate, and you consider only transmission delay, what is the end to end delay to send one packet of length L?
-
-# 4 Packets over 2 Same Rate Links
-$d_{trans} = (L/R) = \tau$
-$d_{e2e} = 5\tau$
-Visual in slides
-
-Two phases:
-- Phase 1 has transmitted P-1 packets out
-- Phase 2 has 1 Packet left
-$$(P + N) \times \tau = d_{e2e}$$
-
-# 4 Packets over 2 Links of different rates
-$$d_{e2e} \approx \frac{\text{Total package size}}{\text{E2E throughput}}$$
-So, estimating
-$d_{e2e} \approx \frac{4 \times L}{R} = 4\tau$
-while the real end to end delay is $5\tau$
-
-# Internet Layering
-Also called TCP/IP model
-## Layers (inverse order due to markdown)
-1. Application
-2. Transport
-3. Network
-4. Link
-5. Physical
-## Applications
-- SMTP 
-- HTTP 
-- DNS
-## Transport
-- UDP
-- TCP
-## Network
-- IP
-- Routing protocols
-## Link
-- Ethernet
-- WiFi
-## Physical
-- Moving individual bits from one node to the next
-
-Terms:
-- Router (Operates on network layer)
-- Switch (Operates on link layer)
-- Modem (Modulation, converting mediums and modes)
-- Access Point (WiFi access)
-
-## Protocols
-Define how peers communicate and exchange information over the network including rules, procedures, and message formats
-
-Application layer protocols:
-- Web server to web client (HTTP)
-
-(More examples for each layer in slides)

+### Encapsulation
 Messages get passed down between each layer, and information gets appended to the header that gets delivered as the payload
