چکیده

This paper investigates the joint use of push-out mechanisms with RED-like discarding policies to support service differentiation in the Internet. The efficiency and the degree of differentiation of a Complete Sharing with push-out, a RIO and a RIO with push-out queues are assessed. Results indicate that push-out used jointly with RED-like policies does not improve the performance.

M1, M2, ..., Mk/G1, G2,..., Gk/l/N Queue with Buffer Division and Push-Out Schemes for ATM Networks (RESEARCH NOTE)

In this paper, loss probabilities and steady state probabilities of data packets for an asynchronous transfer mode (ATM) network are investigated under the buffer division and push-out schemes. Data packets are classified in classes k which arrive in Poisson fashion to the service facility and are served with general service rate under buffer division scheme, finite buffer space N is divided in...

Effectiveness of rate-limiting in mitigating flooding DOS attacks

This paper investigates the effectiveness of rate-limiting in mitigating TCP-based flooding Denial of Service (DoS) attacks. Rate-limiting is used as a DoS defense mechanism to discard a fraction of incoming attack packets. Part of legitimate traffic is, however, mis-detected as attack traffic. The main contribution of this paper is to find out how much a DoS attack can be rate-limited without ...

Intelligent Packet Discard Policies for Improved Tcp Queue Management

Recent studies have shown that suitably-designed packet discard policies can dramatically improve the performance of fair queueing mechanisms in internet routers. The Queue State Deficit Round Robin algorithm (QSDRR) preferentially discards from long queues, but introduces hysteresis into the discard policy to minimize synchronization among TCP flows. QSDRR provides higher throughput and much b...

New High Secure Network Steganography Method Based on Packet Length

In network steganography methods based on packet length, the length of the packets is used as a carrier for exchanging secret messages. Existing methods in this area are vulnerable against detections due to abnormal network traffic behaviors. The main goal of this paper is to propose a method which has great resistance to network traffic detections. In the first proposed method, the sender embe...
