• Optical burst switching
• Joint edge-core node

Optical burst switching (OBS) has been introduced as a short term implementable solution for future all-optical networks. Its performance evaluation received a considerable attention and does not seem to be weaken. In prevalent studies, an OBS network is strictly divided into edge and core domains, while practically for future all-optical mesh network deployments; this is not valid for most of nodes. In these networks, not only a few but probably majority of the nodes will have to combine both functionalities to provide flexible operation. Such nodes are termed herein joint edge-core OBS nodes. In this paper, an architecture of a joint edge-core OBS node is studied and a new scheduling algorithm have been proposed to multiplex the local assembled traffic along with the transit traffic. Thorough simulations have been done on benchmark networks to show the significance of edge scheduling in joint edge-core OBS nodes. [Farrukh Zeeshan Khan.
