Assessment

Coursework: 30%

Exam: 70%

Students are no longer allowed to form their own groups for group work related activities.

You will work in a team of 2 for your coursework.

Interesting to know that my RTSP and RTP video is now in Wireshark.org.

RGB to YUV formula

Y = 0.3R + 0.59G + 0.11B

U = 0.49(B-Y)

V = 0.88(R-Y)

I, P and B Frames

Images in a sequence are classified into 3 types:-

• Intraframe (I-frame)
• Predicted Frame (P-frame)
• Bidirected Frame (B-frame)

Here's a POC of the frames

Miscellaneous

MultiProtocol Label Switching (MPLS):

A data-carrying mechanism that emulates some properties of circuit-switched network over a packet-switched network.

A switching mechanism that imposes labels (numbers) to packets and then uses those labels to forward packets.

The labels are assigned on the edge of the MPLS of the network, and forwarding inside the MLPS network is done solely based on labels.

Labels usually correspond to a path to layer 3 destination address.

MPLS was designed to support forwarding of protocols other than TCP/IP.

In larger network, the result of MPLS labeling is that only the edge routers perform a routing lookup.

All the core routers forward packets based on the labels, which makes forwarding the packets through the service provider network faster.
