في هذا البحث تم توصيف الشبكة بواسط الجبر المنطقي و ذلك لكي يتم فرز الرزم إلى
مجموعتين تتضمن الرزم التي ستصل إلى الهدف و الرزم التي سيتم سحبها وفق حالة
الشبكة و جداول التدفق, تم كتاب التوصيف باستخدام لغة TLA+ التي تعتمد على الجبر
المنطقي الأولي و تم فحص النموذج بواسطة أداة TLCحيث تساعد هذه الطريقه على
عملية التحقق المسبق (Proactive verification) لتعريفات الشبكة و التأكد من أنها
تتعارض مع السياسة الأمنيه العامه.
In this paper the network specification by logic algebra is presented then
the packets are classified into reachable packets and dropped packets
according to the current state of the network and flow tables of switches.
The model specification is written by TLA+ language which is built on
First Order Logic (FOL), and the specification is checked by TLC.
This model will help the programmers to detect the network in proactive
verification and prove that this configuration meets the global policy of
the network.

In this paper we introduce a specification model for the host migration
process in Software Defined Network, and for verifying the reachability
property for packets that do not change after the migration, and achieve
the required modifications to
The mapping of Layer 3 (IP) to Layer 2 (MAC) addresses is a key service in IP networks, and is achieved via the Address Resolution Protocol (ARP) protocol in IPv4. Due to its stateless nature and lake of authentication, ARP is an easy goal to spoofin

Current traditional IP networks start to be complex as the demands of the users are ever-growing. Software Defined Network (SDN) is a new paradigm to ease the management of the network and make the network programmable by decoupling the control plane
ASON\GMPLS based optical network technology has shown high reliability recently, but the issue of unified control of optical networks has become an urgent necessity to cover problems caused by separate control between different optical network layers
