Abstract: With the increasing growth and demand for capacity in national, regional, and even metropolitan optical networks, we are increasing the bandwidth of the channel so that more data can be sent in appropriate time duration. So transmission delay is the main problem to send a large amount of data. To overcome this problem data should be routed to the minimum possible route for this there are various routing protocols which can be used to route the data in optical networks. In this paper I am using two routing protocol to send the data and analyzing the performance parameters such as end to end transmission delay and throughput of the network.

Abstract: By using Steganography the existence of a message can be hide so that if it commonly perfomed successfully then found no suspicion at all. Using steganography, information can be hidden in such as images, audio files, text files, videos files and other means of data transmissions. The main idea for this is to use enough number of bits from each pixel in an image to map them to 26 alphabetic English characters (\'a\'…\'z\') and some special characters that are mostly using in writing a secret message. We know that in every image, there are pixels. Each pixel contains three bytes named as Red, Green and Blue(RGB) channel. The algorithm uses mapping method for data hiding and Pixel Indicator Technique for indication that data is hidden here. The basic concept is to convert secret message into ASCII ( American Standered Code of Information Interchange code.
