Multi-Path TCP (MPTCP) boosts network performance of applications by aggregating bandwidth over multiple paths using sub-flows of the same TCP connection. However, MPTCP suffers from three limitations: (1) it is an end-to-end protocol with no control over the network routes, and sub-flows might end up traversing the same links, (2) it has no dynamic control over choosing the optimal number of sub-flows...
Software Defined Networking is an emerging technology that permits computer network infrastructure to be scaled dynamically as needed while enhancing the manageability of the various network devices in heterogeneous environment as opposed to classical networking. These capabilities emerge from the separation of the data plane from the control plane; thus, allowing the network devices to be programmatically...
The main design principle of Information-Centric Networking (ICN) is the name based routing, that makes users able to ask for a data object by only using its name, and makes the network deliver data to users from a nearby cache if in-network caching is available. Software-Defined Networking (SDN) decouples the control layer from the data layer, so that the complexity, and network control and management...
The proposition of increased innovation in network applications and reduced cost for network operators has won over the networking world to the vision of software-defined networking (SDN). With the excitement of holistic visibility across the network and the ability to program network devices, developers have rushed to present a range of new SDN-compliant hardware, software, and services. However,...
This Paper presents a telco's perspectives and experiences to design and implement open and flexible architecture for Transport SDN (T-SDN). We believe that this could be realized by adopting open source based SDN controllers because they already have widely accepted and referenced architecture with a rich ecosystem. Moreover, we could have further benefits from open source such as reducing time to...
In traditional campus network, application-layer classification is often achieved by using specific devices that support application-layer classification. Since different vendors have different realizations, even the same flow may have different results with different devices. Thus it's hard to set a global consistent application-layer management policy for the whole network. The idea of separating...
