Coolstreaming is a mesh based peer-to-peer (P2P)
video streaming system in which a source node divides
a single video stream into multiple sub-streams.
A client-peer node retrieves the sub-streams
from multiple parent-peer nodes, combining them
into the original video stream. The client-peer
node has two buffers, a synchronization buffer and
a cache buffer, and arriving data-blocks are
synchronized at the synchronization buffer and then
forwarded to the cache buffer. In this buffering system,
data-block synchronization is important to guarantee video
quality. In this paper, we consider the effect of churn on the performance of data-block synchronization scheme with
which data-blocks are simultaneously forwarded just after
all the data-blocks composing a macro data-block arrive
at the synchronization buffer. We assume that data-blocks
belonging to a sub-stream arrive at the client-peer node
according to an interrupted Poisson process.
The synchronization buffer is modeled as
a multiple-buffer queueing system with homogeneous
interrupted Poisson processes, and the mean forwarding
interval is derived. Numerical examples show
that the average forwarding interval increases
as parent-peer nodes leave more frequently. |
