The concurrent-push architecture discussed in the previous two chapters is designed to take advantage of network-level QoS services and is also readily scalable to over ten thousand concurrent streams. In practice, however, not all broadband networks support resource reservation or QoS control. In this chapter we develop an alternative approach to schedule the transmissions of media data from the parallel servers a staggered-push approach. While media servers in the concurrent-push architecture transmit media data simultaneously in proportionally reduced bit-rate, the media servers in staggered push effectively transmit data to the same client in turns, with only one of the servers sending data at any time. As a result, the data traf c will be more bursty and this is also why staggered push cannot easily take advantage of network resource reservation services. In return, the staggered-push architecture can achieve linear scalability, i.e., the perstream server resource requirements (e.g., buffer requirement) are invariant to the scale (number of servers) of the system. This chapter presents this staggered-push architecture, explains its admission, scheduling, and buffer management schemes, and analyzes its performance.

In this chapter we present and analyze quantitatively a staggered-push architecture for scheduling disk retrieval and network transmission in parallel video servers. We prove a remarkable property of the staggered-push architecture the system can be scaled up linearly to an arbitrary number of servers as long as the network has suf cient capacity. We discover that for loosely coupled servers like PC or workstation clusters, server clock asynchrony could lead to inconsistent schedule assignments among different servers. To tackle this problem, we introduce an external admission scheduler to centralize admission control and perform schedule assignments. Apart from inconsistent schedule assignments, we discover that server clock asynchrony could also lead to overlapping between data transmitted from different servers.

This could induce network congestion, leading to video packets being dropped at the network switches and routers. Worse still, the client may not be able to cope with the aggregate data rate even if the network can successfully deliver the data. To tackle this problem, we introduce an over-rate transmission scheme that can effectively prevent traf c overlapping. To evaluate the strengths and weaknesses of the proposed architecture, we use numerical results to compare and contrast staggered-push architecture with the concurrent-push architecture covered in s 10 and 11 using the same system parameters and assumptions.

Figure 12.1 shows the architecture of a parallel video server, comprising multiple autonomous servers connected by an interconnection network. We denote the number of servers in the system by N S and the number of clients by NC . Hence the client server ratio, denoted by , is NC /N S . Each server has separate CPU, memory, disk storage, and network interfaces. A server s storage spaces are divided into xed-size stripe units of Q bytes each. Each video title is then striped into blocks of Q bytes and stored into the servers in a round-robin manner as shown in Figure 12.1. To schedule disk retrievals and network transmissions at the servers, we propose a staggeredpush algorithm where the servers transmit bursts of data to a client in a round-robin manner at the average video bit-rate. Let RV be the average video rate and assume it to be the same for all clients. Then the transmissions from the servers are staggered so that only one of the servers transmits to a receiver at any given time, depicted in Figure 12.2. In this way, there will be at most = NC /N S video blocks being transmitted concurrently at a server. Note that while one can potentially reduce server buffer requirement by transmitting at a rate higher than RV , the client in turn will have to be capable of receiving at such a high data rate. This is less practical as client network connection usually has lower bandwidth and the client device (e.g., set-top box) will likely have limited processing capability. To support staggered push, the server scheduler is divided into two scheduling levels: microround and macro-round as shown in Figure 12.3. Video blocks retrieved in one micro-round will be transmitted in the next micro-round. Let TF be the average time needed to completely transmit a video block of Q bytes. Since a video block is transmitted at a rate equal to the
