This document specifies mechanisms to authenticate the PIM-SM link-local messages using the IP security (IPsec) Encapsulating Security Payload (ESP) or (optionally) the Authentication Header(More)
The efficiency of the external sorting is analyzed in terms of time and I/O complexities. In this paper we have presented a more effective external sorting algorithm, where both the time and output complexities have been reduced significantly and made the sorting faster. Both the time and output complexities of the proposed algorithm are analyzed here and(More)
