Configuring the Jitter Buffer
Jitter, (also known as latency or delay), is the amount of time it takes for a packet of data to get
from one point to another. A jitter buffer is a temporary storage buffer used to capture incoming data
packets. It is used in packet-based networks to ensure the continuity of audio streams by
smoothing out packet arrival times during periods of network congestion. Data packets travel
independently and arrival times can vary greatly depending on network congestion and the type of
network used, i.e. LAN versus wireless networks. The concept of jitter buffering is displayed visually
in the following image.
Jitter-buffer management is encompassed within Tieline's SmartStream IP technology which can:
·
Remove duplicate packets.
·
Re-order packets if they arrive out-of-order.
·
Repair the stream in the event of packet loss (error concealment).
·
Manage delay dynamically based on current network congestion.
·
Manage forward error correction (FEC).
