....different levels of survivable services. In this formulation, we also incorporate ideas such as hard or soft survivable capability (discussed in the next section) While, over the years, network survivability has been addressed for circuit switched, ATM and fiber networks (see, for example, [2, 3, 4, 5, 8, 9, 10, 13, 15] for a sampling of work) MPLS allows the capability to address traffic engineering along with survivability for a new class of problems. For example, Wang and Wang [14] have addressed the explicit routing models for MPLS traffic engineering. The work that is closest to ours is by Kodialam and ....

....is not incorporated, a network (where services do backlog traffic after a failure) may be under designed resulting in noticeably longer transient period than any acceptable threshold. 1. INTRODUCTION Designing networks for survivability has received considerable attention in recent years [2, 3, 9, 11, 13, 16, 17, 19, 21, 22, 26, 27]. For ATM based broadband networks, multi layer network survivability and restoration can be possible at the following levels: transmission level, virtual path level, and virtual circuit or connection call level. At transmission level, SONET self healing ring for restoration is a viable ....

....level restoration may not be applicable in certain failure scenarios, such as a line card or a device failure) This, in turn, means that survivability and restoration at VP and or VC level would also be necessary. For call virtual circuit level restoration, the reader is directed to work such as [7, 21, 24, 25]. Our present paper concentrates on virtual path level survivability and restoration. Research supported by the US National Science Foundation under grants NCR 9506652 and CDA 9422092. The virtual path concept for ATM networks design and management have been addressed by numerous researchers ....

....of a link failure in a generic virtual circuit based packet network. While the impact on the traffic performance due to a failure in the presence of routing has received considerable attention in circuit switched networks (that employ dynamic routing) and virtual circuit based packet networks [2, 12, 17, 19, 23, 24, 30, 34, 37], it has received little attention in the case of TCP IP network. In fact, most of the work devoted to TCP performance and its extension consider a single link or a linear network (no routing) in their studies. Another congestion (rather, a perceived congestion) at the TCP level can be due to ....

....from the managers of the physical layer network is useful in initiatingrecovery mechanisms for affected links. 6.1. Illustrative Examples We now discuss two simple illustrative examples to show the need for multi network coordination. More extensive results along this line can be found in [13, 16]. The first example consists of four nodes in the provider network and three nodes in the user network as shown in Figure 3. The links connecting the nodes U0, U1 and U2 in the user network are logical links which are routed through the physical links in the provider network. Each of these ....

....the network to a failure is a critical issue. While there has been considerable work on understanding the impact of a network failure on routing, design and performance for other types of networks such as circuit switched networks, virtual circuit based packet networks including ATMbased networks [2, 3, 8, 11, 12, 19, 21], there has been very limited work in this area for IP datagram networks. In this work, we consider the issue of network performance of a wide area datagram network, such as the Internet, supporting multicast traffic along with unicast traffic, especially when subjected to a link failure. Failure ....

....Additionally, to reduce loss of packets for multicast services or to reduce delay for unicast services under a failure, having priority queueing at the nodes is desirable; but, more importantly, the network has to be dimensioned appropriately. Similar to the work done for other types of networks [5, 11, 12], proper network dimensioning methods need to be developed to address for multicast based services that have quality of service requirements, and, especially, to address for a network outage.

.... types of dynamic call routing for single service (voice) circuit switched networks and their advantages have been quantified [3] 5] 9] 14] 20] 25] 32] and some work on considering (single service) switched and cross connect networks together has also been addressed [4] 15] 22] [29], primarily for single service networks to address network survivability. Broadband networks based on ATM, however, provide flexibility through bandwidth unit granularity and virtual paths. Depending on the type of service, the peak rate for the service need not be allocated at the time of ....

....transmission network. Thus, we are moving to an environment that we have coined the multinetwork environment. In such environment, in each of these networking layers, different types of failures attacks and responses are possible. Some work in recent years has addressed this subject to some extent [7, 8, 21, 24, 25, 26]. It remains to be seen the impact of the failure propagation from one network to another, how the restoration process at each of these layers interacts with one another, whether they can make the best use of the network resources, and what type of network management coordination is needed for ....
