iREX MPO : A Multi-Path Option for the iREX Inter-Domain QoS Policy Architecture
2008
2008 IEEE International Conference on Communications
Preserved Fulltext
In iREX, each policy reservation is deployed on a single E2E ID path made up of the most "desirable" (i.e. cheapest and least congested) ISP resources. ...
accommodate ISPs that prefer redundancy when deploying ID QoS policy, in this paper we introduce an extension to the iREX architecture that gives an originating ISP a multipath option (MPO) when deploying a reservation ...
We define a link as congested when more than 50% of its bandwith is in use. ...

When an application needs to reconfigure the underlying network, it reserves a point to point link from DRAC using a web service interface. ...
DRAC then computes the availability of the connection, determines the best route for the signal and requests the connection from CPL using the Domain Optical Controller. ...

A WDM-based all-optical network consists of wavelength switching devices interconnected by point-to-point fiber links in an arbitrary mesh topology. ...
Our work focuses on such dynamic online integrated RWA problem, where incoming connection requests are routed on the optical transport network using the current state of the network, such as link load ...
Each new connection request can be routed over a direct lightpath modelled as a single cut-through edge in our multi-graph, or over a sequence of lightpaths (a multi-hop path at the IP level, where each ...

We formally define and address the associated problem, the Bulk Data Routing and Transfer(BDRT) and present a linear programming-based solution to it, optimal in both routing and time domains. ...
Our optimization jointly addresses routing of transfers within the overlay and the time-domain scheduling of transfer bandwidths. ...
BDRT is slower up to the point where K=70 (low connectivity), respectivelly K=50 (full mesh), at which point BDTS/* become comparable or slower. ...

Our work deals with the energy consumption issue in dedicated network with bandwidth provisionning and in-advance reservations of network equipments and bandwidth for Bulk Data transfers. ...
However, with the emergence of the MPLS (Multi-Protocol Label Switching) [54] standard with traffic engineering and explicit routing features, it becomes possible to disconnect the reservation management ...

The cluster incorporates a cubic network topology based on inexpensive commodity 24-port gigabit switches and point to point connections through the second gigabit port on each Linux server. ...
We point out that the same cabling effort is required even for more expensive multi-port switches so there is no significant overhead in manual labour. ...
In the second stage, it was necessary to wire the CDCC network using the point to point connections through the second network port on each node. ...

In such cases reservation signalling would for example occupy more of the available radio resource when utilising D-TDMA. ...
For both approaches instability of the contention mechanism(s) during heavy load requires a form of connection admission control to ensure successful outcome of the process for start-up of new traffic ...
This is quite similar to the OLSR routing protocol where multi relay points (MRPs) are selected. ...
