... received in revised form 2 August 2007 Abstract. This paper considers the problem of dynamicsurvivable routing inWDM networks with single link failure model. This work mainly concerns in how to dynamically ... two network nodes. The routing problem that tries to determine a working path and a protection path for a connection request in dynamic WDM networks is referred to dynamicsurvivable routing. ...

IP Addressing An IP address ... 172.16.0.0) uses a network prefix of /16, or 16 bits. However, using CIDR, the administrator can elect to assign 20 bits of the IP address to the network, resulting in a network prefix of /20. ... deficiency, Addressing inIP Networks Without an address, you can put a stamp on an envelope, put it in the mail, and it is not going to go anywhere.
