....server. Both the packet redirector in SPIRAL and the network switch filter (call proxy) in Slice manipulate packets at datalink level based on application level information but in the opposite direction. There are many approaches to implement request distribution across a number of servers [6, 13, 7, 26]. Since packet redirection in SPIRAL happens at the datalink layer, SPIRAL can be used in conjunction with these solutions seamlessly. On the other hand, although we focused on third party transfer with NADs in this paper, the packet redirection scheme used in SPIRAL can also be deployed among the ....

....which is not usually a problem as clustered servers are usually interconnected by high speed LANs, and it could be possible to use proprietary solutions like Cisco switch to switch interconnects to propagate MAC address between different switches. Research prototypes of L4 2 clustering are ONE IP [24] from Bell Labs and LSMAC [20] from the University of Nebraska. Most of the commercial load balancing solutions provide this kind of clustering as an option. It is also known as Load Sharing Using Network Address Translation (LSNAT) and it is an Internet standard detailed in RFC 2391[30] ....

....than one request routing mechanism. In the remaining part of this subsection we describe some of research prototypes and commercial products based on a layer 4 Web switch. Specifically, we focus on one way architectures which use packet forwarding (i.e. IBM Network Dispatcher [59, 61] and ONE IP [41]) as it turns out to be a scalable solution. We also consider some two way architectures that use packet double rewriting. This routing mechanism is implemented either by a special purpose hardware (i.e. Cisco s LocalDirector [33] or by a software running on a common operating system (i.e. ....

....are handled as follows. The environment consists of a primary and secondary dispatcher. In the event of a primary dispatcher failure, the secondary dispatcher detects the missing heartbeat message of the primary dispatcher, and employs the IP address of the primary dispatcher to continue operation [7, 17, 15]. The availability of data in the presence of lookup service node failures is realized by maintaining multiple directory servers. The availability of Web Services is supported using a primary and secondary copy of each service that resides on two different nodes. The proxy objects for a Web ....

....A centralized dispatcher is also the performance bottleneck for a cluster. To support the very high hit rates of a cluster, specialized and expensive technologies are used to implement the dispatcher. Current research has addressed clustering without the need for a centralized dispatcher. ONE IP [11] and Distributed Packet Rewriting (DPR) 4] are two such methods. They are described in more detail later in this paper. Building on the previous work of ONE IP, we explore new methods of building a server cluster without requiring a centralized dispatcher and or any configuration changes to ....

In DPR each server machine in a cluster has knowledge of the load of all other server machines. IP addresses of all server machines are published, allowing any of the machines to receive requests. An incoming request to any one server machine can be handed off (using TCP connection splicing) ....

....Caching improves the response time of subsequent requests that can be satisfied directly from the proxy cache. Server clusters A single dispatcher intercepts all Web requests and redirects them to one of the servers in the cluster. The requests are intercepted at the network protocol level [12, 16]. Since a server cluster typically is located within a single LAN, the server selection is mostly based on server load and availability within the cluster. DNS aliasing A single host name is associated with multiple IP addresses. A modified DNS server selects one of the IP addresses based either ....

....Internet services. They introduce a data semantics called BASE (Basically Available, Soft state, Eventual consistency) that offers advantages for web search and document filtering applications. The architecture Fox describes is, in fact, quite popular in today s large scale web servers [23, 43, 119, 123, 144]. Our work shares many of their goals: building scalable Internet services with a semantics weaker than traditional database systems. As in Fox s work, we observe that ACID (Atomic, Consistent, Isolated, and Durable) semantics [13, 68] adopted in traditional database systems may be too strong for ....
.... distribute requests to cluster nodes (e.g. Cisco Local director [36] F5 BigIP [115] Foundrynet ServerIron [58] and Resonate Central Dispatch [130] Some cluster based Internet servers balance the load on the back end storage servers by dispatching requests intelligently at the front end nodes [43, 61, 144]. 29 These systems distribute the workload round robin or by using a simple load measure, such as queue length or average response time. Pai and others describe a LARD (Locality Aware Request Distribution) mechanism for cluster based web services [8, 119] In LARD, the front end nodes analyze the ....

.... that does not require a modification of the packet addresses because packet forwarding to cluster nodes is done at the MAC address level [10] A different forwarding approach to configure a Web system with multiple servers uses the if config alias option, which is available in most UNIX platforms [8].
